California passes guidelines for $1 billion of cap-and-trade revenue

Promoted in Energy Efficiency section: 
0

 

On September 30, California Governor Jerry Brown signed two bills into law, establishing guidelines on how an expected $1 billion-plus of annual revenue from the state’s cap-and–trade program will be disbursed. The two laws do not identify specific projects that will benefit from the revenue, but they provide a framework for how the state will invest cap-and-trade program revenue into local projects. California’s first quarterly cap-and-trade GHG allowance auction is set for November 14, 2012. At least 21,804,529 greenhouse gas (GHG) allowances, in this first auction, each representing one ton of carbon dioxide, will be auctioned off to over 600 approved industrial facilities and utilities.

The first law, AB 1532, requires that the revenue from allowance auctions be spent for environmental purposes, with an emphasis on improving air quality. The second, SB 535, requires that at least 25 percent of the revenue be spent on programs that benefit disadvantaged communities, which tend to suffer to a disproportionate extent from air pollution. The California Environmental Protection Agency will identify disadvantaged communities for investment opportunities, while the Department of Finance will develop a 3-year investment plan and oversee the expenditures of this revenue to mitigate direct health impacts of climate change.

These two new laws follow final regulations, adopted by the California Air Resources Board (ARB) on October 20, 2011 for a cap-and-trade program that will help the state reduce greenhouse gas emissions to 1990 levels by the year 2020. The development of California’s cap-and-trade system is authorized by the California Global Warming Solutions Act (AB 32), which was signed into law by Governor Schwarzenegger in 2006.

Beginning in 2013, cap-and-trade regulations will apply to all major industrial sources and electric utilities, and will expand in 2015 to cover the distributors of transportation fuels, natural gas, and other fuels. The amount of allowances available to these sources is set to decline by about 3 percent each year as the cap is lowered and emissions are reduced.

Massachusetts ranked number one in energy efficiency by ACEEE

Promoted in Energy Efficiency section: 
0

Massachusetts topped energy efficiency rankings produced by the American Council for an Energy Efficient Economy (ACEEE) for the second year in a row. Massachusetts has been a consistent high performer according to ACEEE’s methodology; in the six years the organization has published its state energy efficiency scorecard, Massachusetts has scored among the top ten each year.

ACEEE attributes Massachusetts’s success to its continued implementation of the Green Communities Act of 2008 (GCA). Further, Massachusetts Governor Deval Patrick recently signed into law Senate Bill 2395, a piece of legislation expanding upon GCA. The law extends contracts between utilities and renewable energy firms and increases the cap on net metering.

In constructing scores, ACEEE considers a variety of state energy efficiency policies and weights them according to their potential energy savings. ACEEE updated its methodology this year, changing how some policies were scored to “better reflect potential energy savings, economic realities and changing policy landscapes.” Despite changes that increased the stringency of scoring, Massachusetts remained highly competitive along with California, Oregon, New York, and Vermont.

Jump to Workshop Presentations
 

Background

In major OECD countries, direct and indirect emissions of GHG from industry account for up to one-third of total end-use greenhouse gas (GHG) emissions. Policymakers at a variety of government levels are considering policies to address these emissions. Benchmarking, which assesses GHG emissions performance across facilities or against a common standard, can be used in various policy approaches, including:

·      Regulation of GHG emissions through a cap-and-trade program, along with free allocation of emissions allowances to industry sectors in proportion to output based on an emissions performance benchmark;

·      Regulatory GHG performance standards, where individual facilities are required to meet an emissions performance standard;

·      Energy efficiency targets, either regulatory or voluntary; and

·      Voluntary performance goals, in which participating companies commit to achieving a particular emissions benchmark by a particular year.

Against this background, the North American greenhouse gas (GHG) regulatory landscape has recently been evolving at both federal and sub-national levels, putting GHG emissions benchmarks up on the agenda of U.S. states and Canadian provinces committed to reducing their emissions. Beyond North America, other jurisdictions are also developing benchmarks as a means to reduce GHG emissions, particularly in the European Union as part of the revision of its emissions trading system (ETS) in preparation of Phase III.

Workshop Objectives

·      Explore approaches to developing industrial greenhouse gas emissions benchmarks that could inform either allowances allocation under a GHG cap and trade program or performance-based GHG (i.e. performance standards) regulations;

·      Gain understanding of current approaches to industry benchmarking, including those being implemented in the EU, California and elsewhere;

·      Examine international best practices to identify appropriate sectors with which to begin benchmarking and how to design benchmarks;

·      Identify benefits of coordinating benchmarking approaches, inter alia with regard to competitiveness and leakage issues;

·      Generally foster broader communication and collaboration on climate policy by the example of benchmarking; and

·      Identify possible next steps for continued collaboration between NA2050 and ICAP.

Format

1 day public workshop in New York City with presentations and participation from ICAP and NA2050 representatives and from selected experts from various backgrounds (academia, non-profit, industry). Presentations will be followed by open discussions amongst the participants. About 60 attendees are expected.

Participants

·      Representatives from ICAP members and observers engaged in and/or interested in developing benchmarks for allocation in an emissions trading system;

·      Government officials from U.S. States and Canadian provinces, e.g. from RGGI, WCI and NA2050 jurisdictions, as well as from the U.S. and Canadian federal governments;

·      Industry representatives e.g. from the refinery, steel, cement, pulp and paper sectors;

·      Representatives from the non-governmental sector and from academia.

Co-hosts:  International Carbon Action Partnership (ICAP) and the North America 2050 Initiative (NA2050)

New York develops tax incentives to increase solar energy capacity

Promoted in Energy Efficiency section: 
0

On August 17, three new pieces of legislation establishing and expanding financial incentives for solar energy projects were signed into law in New York by Governor Andrew Cuomo. Such incentives are necessary to ensure the competitiveness of solar energy production given its current high price relative to conventional sources of electrical generation. 

Bill A34B provides for a 25 percent tax credit to homeowners, up to $5000, of the cost of installation of certain solar energy equipment. The law also extends this tax credit to homeowners either leasing solar equipment or purchasing power produced by solar equipment in agreements lasting at least ten years. This law takes effect immediately and lasts 14 years. 

Bill A10620 extends a maximum $62,500 real property tax abatement of 2.5 percent between January 2013 and January 2015 for homeowners installing solar energy equipment through 2014. Bill A05522B provides for exemptions to sales taxes imposed by the state on commercial solar energy equipment and also allows for localities to provide the same exemption. These laws will take effect in January 2013. 

Governor Cuomo enumerated benefits of these incentives, stating that the laws “demonstrate the state’s commitment to reducing energy costs, growing our green energy sector, creating jobs, and protecting the environment.” The New York legislature cited the importance of these initiatives in achieving the ambitious goal set by New York’s renewable portfolio standard of generating 30 percent of the state’s electricity using renewable sources by 2015. In 2011, 24 percent of electricity consumed in New York was produced by renewable sources. 

This legislation furthers the goals of the Governor’s NY-SUN Initiative, which aims to rapidly increase solar energy generation in the state, doubling the level of photovoltaic capacity installed in 2012 and to quadruple the amount of installation in 2013 compared with 2011. These three laws represent the latest legislative tools in a larger set of policies to increase solar generating capacity including competitive grants financing large-scale commercial solar projects and noncompetitive grants funding smaller scale residential projects

California holds trial allowance auction in preparation for cap-and-trade implementation

Promoted in Energy Efficiency section: 
0

On August 30, 2012 the California Air Resources Board (CARB) conducted a test run of the online allowance auction system for the state’s greenhouse gas emissions trading program. The trial auction, which involved no exchange of money or allowances, was conducted to enable market participants to gain firsthand experience with the auction user interface and to allow CARB to discover and correct problems before the first real auction, scheduled to take place on November 14, 2012. The real event will involve the auctioning of 60 million allowances, each representing the right to emit one metric ton of carbon dioxide equivalent.

Auction participants were able to practice completing the online auction application, opening accounts with the financial services administrator, and having bid guarantees processed in the days before the practice auction was held. CARB further provided online training before the event. On the day of the trial run, participants had a three-hour window to submit bids. More recently, CARB surveyed participants for feedback to improve the system. CARB will not release the auction settlement price or the number of allowances sold to avoid creating improper price signals in the allowance market.

The development of a cap-and-trade system for greenhouse gases was required by the California Global Warming Solutions Act, otherwise known as AB 32, which was signed into law by former Governor Schwarzenegger in 2006. The aim of this legislation is to reduce greenhouse gas emissions in California to 1990 levels by 2020. To that end, the law also requires mandatory GHG emissions reporting, determination of baselines emissions, and establishment of early actions.

Enforcement of the cap-and-trade program begins on January 1, 2013 when electric utilities and large industrial emitters will be covered. The program will expand to include fuel distributors in 2015, eventually covering 85 percent of California’s GHG emissions. The cap is set to decline initially at a rate of two percent annually until 2014 and three percent annually thereafter until 2020. Compliance costs are minimized through trading of allowances and maintaining four percent of allowances in a reserve that will become available if the price exceeds a specified threshold. Allowances may be banked by emitters to be used in the future and compliance periods are three years long to smooth variations in allowance price and product output, respectively. To further increase flexibility, the program allows emitters to purchase a limited number of offset credits, which represent emission-reduction projects taking place outside of the cap-and-trade program. Regulated entities must report emissions annually and face penalties for exceeding allowances or missing compliance deadlines.

In developing and implementing the cap-and-trade system, California has been working closely with the Western Climate Initiative, which is providing administrative and technical support. Such state and regional climate programs capping GHG emissions are important in the absence of national cap-and-trade legislation.

Overview

The transportation sector is one of the largest sources of U.S. carbon dioxide emissions, second only to the power sector. Cars and light-duty trucks are responsible for 60 percent of transportation emissions. Medium- and heavy-duty vehicles, which include tractor-trailers, large pickups and vans, delivery trucks, buses, and garbage trucks, produce 23 percent of transportation emissions.

The federal government has regulated the fuel economy of cars and light-duty trucks for decades, with the latest rules in 2012 dramatically increasing fuel economy and decreasing greenhouse gas emissions. A 2010 rule raised the average fuel economy of new passenger vehicles to 34.1 miles per gallon (mpg) for model year 2016, a nearly 15 percent increase from 2011. A second rule, finalized in 2012, will raise average fuel economy to up to 54.5 mpg for model year 2025, for a combined increase of more than 90 percent over 2011 levels. The standards also will reduce the carbon intensity of these vehicles by 40 percent from 2012 to 2025.

The standards were adopted by the Environmental Protection Agency (EPA) and the National Highway Traffic Safety Administration (NHTSA) with the cooperation of major automakers and the state of California. Together, the standards represent the largest step taken by the federal government directed at climate change.

Other benefits include improving U.S. energy security and saving drivers money. The car rule for model years 2017 to 2025 is projected to cut annual U.S. oil imports by an additional 6 percent by 2025 from what would happen otherwise, or 400,000 barrels per day. When combined with the rule for model years 2012 to 2016, U.S. oil imports are expected to decline by more than 2 million barrels per day by 2025, equivalent to one-half of the oil the U.S. imports from OPEC countries each day, according to EPA. 

Higher vehicle costs for fuel efficiency improvements will be far outweighed by fuel savings, with the average driver saving about $8,000 net over the lifetime of a model year 2025 car compared to a model year 2010 car.

Fuel economy and greenhouse gas standards were first established for medium- and heavy-duty vehicles in 2011. These standards are projected to save a combined $50 billion in fuel costs, 530 million barrels of oil, and 270 million metric tons of carbon emissions over the lifetime of vehicles for model years 2014 to 2018. EPA and the Department of Transportation proposed new rules in June 2015 for model years after 2018. 

Figure 1: 2013 U.S. carbon dioxide emission, by sector and transportation source

The transportation sector is responsible for more than one-third of U.S. carbon dioxide emissions. Light-duty vehicles account for almost two-thirds of transportation sector emissions; medium- and heavy-duty vehicles account for almost a quarter.

Light-Duty Vehicle Standards Timeline (1975-2012)

The federal government has regulated fuel economy through standards for cars and light-duty trucks for decades. The 1973 Arab oil embargo prompted Congress to pass legislation in 1975 that introduced Corporate Average Fuel Economy (CAFE) standards for new passenger vehicles only. The purpose was to improve the fuel economy of the passenger vehicle fleet to reduce oil imports.

NHTSA, an agency within the U.S. Department of Transportation (DOT), administered the original CAFE program while EPA was responsible for establishing the testing and evaluation protocol for assessing compliance and calculating the fuel economy for each manufacturer. These responsibilities are the same today.

CAFE is the sales-weighted average fuel economy (in mpg) of the passenger cars or light-duty trucks for a manufacturer's fleet. See Calculating Light-Duty Vehicle CAFE Then and Now below for details of how EPA determines compliance. NHTSA fines manufacturers that are out of compliance. NHTSA has so far collected almost $819 million in fines over the life of the CAFE program.

Since 1975, a number of changes have been made to the standards. Figure 1 provides an annotated history of the U.S. CAFE standards. A number of other countries have also instituted fuel economy standards, with most establishing more aggressive targets than the United States. See here for more details.

Recent Legal History

Under the federal Clean Air Act, California is the only state with the ability to set air emission standards for motor vehicles, as long as these standards are as stringent as the federal standards and the state receives a waiver from EPA. Once California receives an EPA waiver, other states can adopt California's standards.

In 2002, California enacted the Clean Cars Law (AB 1493) to set vehicle emissions standards for greenhouse gases. In April 2007, the Supreme Court ruled that EPA has the authority to regulate greenhouse gas emissions from the transportation sector under the Clean Air Act. In December 2007, a judge threw out a lawsuit by automakers attempting to block California from implementing AB 1493. The intersection of fuel economy standards and greenhouse gas emission standards was beginning to become clear (see here for more on California vehicle standards).

Back in December 2005, California had applied for an EPA waiver to implement its greenhouse gas standards. In March 2008, EPA denied California's waiver request. Upon taking office in January 2009, President Barack Obama ordered EPA to reconsider that denial.

In June 2009, EPA granted a waiver allowing California to regulate greenhouse gas emissions from vehicles within the state beginning with model year 2009. On September 15, 2009, EPA and NHTSA issued a joint proposal to establish new vehicle standards for fuel economy and greenhouse gas emissions for model years 2012 to 2016, which were finalized on April 1, 2010. The joint proposal reflected an agreement among EPA, NHTSA, California, and most major automakers. California promptly agreed to adopt the federal standards in lieu of its own separate standard; and did so again with the latest standards covering model years 2017 to 2025.

Light-Duty Vehicle Standards (Model Years 2012 to 2025)

The latest passenger vehicle standards, finalized in August 2012, cover passenger cars, light-duty trucks, and medium-duty passenger vehicles, from model year 2017 to 2025. The standards build off those set in April 2010 for model years 2012 to 2016. The standards are based on the vehicle's footprint, which is a measure of vehicle size (see Calculating Light-Duty Vehicle CAFE Then and Now). 

Because NHTSA cannot set standards beyond model year 2021 due to statutory obligations and because of the rules' long time frame, a mid-term evaluation is included in the rule. Thus, standards for model years 2022 through 2025 are considered "augural" by NHTSA. The comprehensive evaluation by both EPA and NHTSA will allow for any compliance changes if necessary for the later years covered by the rule.

As seen in Table 1, the greenhouse gas standard from EPA requires vehicles to meet a target of 163 grams of carbon dioxide equivalent (CO2e) per mile in model year 2025, equivalent to 54.5 mpg if the automotive industry meets the target through only fuel economy improvements.

As seen in Table 2, the fuel economy standard from NHTSA requires vehicles to meet an estimated combined average of up to 48.7 mpg in 2025. This estimate is lower than the mpg-equivalent of the EPA target for 2025 mentioned above (54.5 mpg) , because it assumes that manufacturers will take advantage of flexibility available under the law designed to reduce the cost of compliance. See Light-Duty Vehicle Program Flexibilities for more information.

This table is based on CAFE certification data from model year 2010, a car-truck sales split from the Energy Information Administration's Annual Energy Outlook for 2012, and future sales forecasts by JD Powers.

Medium- and Heavy-Duty Vehicle Standards

Medium- and heavy-duty trucks make up only 5 percent of vehicles on the road but account for about a fifth of U.S transportation emissions. This category includes tractor-trailers, large pickups and vans, delivery trucks, buses, and garbage trucks.

In June 2015, EPA and NHTSA proposed new fuel economy standards for model years 2021-2027, building on earlier standards put in place in 2011 that were the first of their kind in the world.

The earlier standards, for model years 2014 to 2018, are cumulatively projected to save a combined $50 billion in fuel costs, 530 million barrels of oil, and 270 million metric tons of carbon emissions over the lifetime of the heavy-duty vehicles.

EPA estimates the new phase 2 standards for model years 2021-2027 will cut greenhouse gas emissions by more than 33 million metric tons annually by 2025 – the equivalent of the annual emissions from 7 million light-duty vehicles. EPA estimates the rules will also reduce oil consumption by 1.8 billion barrels, and lower fuel expenditures by $710 billion over the life of vehicles sold under this standard. 

In model year 2027, the buyer of a new vehicle would recoup the extra cost of technology used to achieve the standard within:

  • 2 years for tractor/trailer combos
  • 3 years for pick-ups and vans
  • 6 years for vocational vehicles

EPA’s proposed Phase 2 standards would be phased in from model years 2021 to 2027, though proposed standards for some categories of box trailers begin in model year 2018. All proposed CO2 and petroleum use reductions are relative to the final Phase 1 standards, which are being implemented through 2017, with the exception of trailers, which had not previously been regulated. Notably, Phase 2 standards use different methodologies and test procedures, and should not be construed as directly comparable to Phase 1 standards.

The proposed standards described below represent Alternative 3 of the proposed standards, which would take effect in 2021 and would provide a full 10 years of lead time. Standards are divided into four segments.

  1. Combination Tractors, which are responsible for almost two-thirds of fuel consumption from medium- and heavy-duty trucks, would achieve a 24 percent reduction in fuel consumption by model year 2027.
  2. Trailers Pulled by Combination Tractors, which were not included under Phase 1 standards, would achieve an 8 percent reduction in fuel consumption by model year 2027.
  3. Heavy-Duty Pickup Trucks and Vans would have to improve fuel economy by 16 percent by model year 2027. The standards rely on a "work" factor, which considers the vehicle's cargo capacity, towing capabilities, and whether it has 4-wheel drive. Similar to the light-duty standards, the standards are based on the manufacturer's sales mix.
  4. Vocational Vehicles (delivery trucks, buses, garbage trucks) would achieve a 16 percent reduction in fuel consumption by model year 2027.

NHTSA and EPA designed the standards based on the kind of work the vehicles undertake. Heavy-duty pickup trucks and vans must meet a standard specified similarly to passenger vehicles, gallons of fuel per mile and grams of CO2e per mile. The other two categories must meet a standard based on the amount of weight being hauled (fuel consumed or grams of CO2e emitted per ton of freight hauled a defined distance).

Why Consumers Undervalue Fuel Economy

U.S. fuel economy and greenhouse gas standards exist because individual drivers tend to value savings from fuel economy much less than society as a whole, which leads to more oil consumption than would occur if societal benefits were taken into account. The benefits to society of higher fuel economy include, but are not limited to, reduced impacts on global climate, improved energy security, and overall consumer savings. But those benefits are not top of mind when a consumer buys a car.

In addition, when making purchasing decisions, most people assume a dollar today is worth more than a dollar in the future since the dollar today can be invested and grow in value over time. The value people assign to a dollar in the future compared to a dollar today is known as the discount rate, or the interest rate they would expect on a dollar invested today. For example, a discount rate of 20 percent means consumers assume they will make 20 percent interest annually on money invested today, which is unlikely. Thus, the higher the discount rate a consumer uses, the more likely a consumer is to invest that money instead of spending it on a product. 

David Greene from Oak Ridge National Laboratory found that the value consumers place on fuel economy savings for cars varies widely, but empirical research reveals a discount rate between 4 and 40 percent. The discount rate that society puts on fuel savings is much closer to 4 percent, meaning consumers often substantially undervalue fuel economy.

Calculating Light-Duty Vehicle CAFE Then and Now

Each automaker's fleet-wide average fuel economy consists of three potential fleets: domestic passenger cars, imported passenger cars, and light-duty trucks. (The split between domestic and imported cars exists to support domestic automobile production.) With its focus on fuel efficiency, the standard must capture the fuel economy of each vehicle traveling the same number of miles. The harmonic mean of the fleet accomplishes this task (versus the simpler arithmetic mean). That is, instead of dividing the sum of the fuel economy rates in mpg for each vehicle by the total number of vehicles (the arithmetic mean), the reciprocal of the arithmetic mean is used as follows:

 

Where Production is the number of vehicles produced for sale for each model and TARGET is the fuel economy target for the vehicle.

Before 2008, the target fuel economy was the same for all vehicles. In 2008, NHTSA changed the target to a bottom-up one based on attributes of each vehicle instead of a top-down uniform target across an entire automaker's fleet. The vehicle footprint target for light-duty trucks through model year 2016 and for automobiles through model year 2025 is determined as follows:

 

where FOOTPRINT is the product of the vehicle's wheelbase and average track width in square feet, a and b are high and low fuel economy targets that increase from 2012 to 2025 and are constant for all vehicles, and c and d are adjustment factors. Parameter c is measured in gallons per mile per foot-squared, and parameter d is measured in gallons per mile.

For light-duty trucks beginning in model year 2017, an additional variation of the TARGET calculation is considered. This additional variation establishes a "floor" term, which prevents any footprint target from declining between model years. The definitions of parameters a, b, c, and d correspond to e, f, g, h, accordingly. However, the values of these parameters are different.

 

The idea behind an attribute-based standard is that the level of difficulty of meeting the standards is the same for smaller and larger vehicles. A uniform standard, on the other hand, is easier to meet for smaller vehicles (i.e., those with a smaller footprint) than for larger vehicles.

Light-Duty Vehicle Program Flexibilities

The EPA and NHTSA programs have a number of features to make compliance for manufacturers more cost-effective, while also encouraging technological innovation like plug-in electric vehicles. Since there are two programs to comply with, the details of both programs are stipulated below.

  • Credit Trading System: Both programs include a credit system allowing manufacturers to carry efficiency and greenhouse gas credits forward by up to five years and backward up to three years to achieve compliance and avoid fines. Manufacturers can also transfer credits between cars and trucks of their fleet and trade credits with other manufacturers. Additionally, CO2 credits generated for EPA compliance from model year 2010 to 2016 can be carried forward as far as model year 2021.
  • Air Conditioning Improvements: Both programs allow manufacturers to use air conditioning (A/C) system efficiency improvements toward compliance. For the NHTSA program, credits will depend on fuel consumption reductions. The EPA program allows credits for reductions in fuel use and refrigerant leakage, as well as the use of alternative refrigerants with lower global warming potential.
  • Off-Cycle Credits: Current test procedures do not capture all fuel efficiency and greenhouse gas improvements available. Technologies that qualify for additional credit might include solar panels on hybrid vehicles, active aerodynamics, or adaptive cruise control. In addition, manufacturers can apply for credit for newer technologies not yet considered if they can provide sufficient data to EPA.
  • Zero Emission, Plug-in Hybrid, and Compressed Natural Gas Vehicle Incentives: To encourage plug-in electric vehicles, fuel cell vehicles, and compressed natural gas (CNG) vehicles, EPA has included a credit multiplier in the rule for model years 2017 to 2021. In the compliance calculation for GHG Emissions, all-electric and fuel cell vehicles count as two vehicles beginning with model year 2017 and phasing down to 1.7 by model year 2021. Plug-in hybrid electric vehicles begin with a multiplier of 1.6 in model year 2017 and phase down to a value of 1.3 by model year 2021. Electric and fuel cell vehicles sold during this period will count as emitting 0 grams of CO2e per mile. There is no multiplier for model years 2021 to 2025 and EPA limits the zero-grams credit based on vehicle sales during this period. The cap for model years 2021 to 2025 is 600,000 for companies that sell 300,000 of these vehicles from model year 2019 to 2021 and at 200,000 otherwise. Beyond that number, manufacturers of electric and fuel cell vehicles will need to account for their upstream emissions (i.e., electricity generation or hydrogen production) using accounting methodologies defined in the rule.

    EPA has also included credit multipliers for CNG equivalent to plug-in hybrid electric vehicles: 1.6 in model year 2017 and a phase down to 1.3 by model year 2021. Unlike electric and fuel cell vehicles, GHG emissions from CNG vehicles will be measured by EPA.

    In contrast, NHTSA does not believe it has the legal authority to offer credit multipliers. Existing legal authority does allow NHTSA to incentivize alternative fuels, like natural gas, however, by dividing vehicle fuel economy by 0.15; in other words, an electric, fuel cell, or CNG vehicle that has a fuel economy of 15 mpg-equivalent will be treated as a 100 mpg-equivalent vehicle.

  • Truck Hybridization: Both programs offer incentives to add battery-electric hybrid support to full-size trucks. Mild hybrid pickup trucks (15-65 percent of braking energy is recaptured) would be eligible for a per vehicle credit of 10 grams of CO2e per mile during model years 2017 to 2025 so long as the technology is incorporated into 20 percent or more of the company's model year 2017 full-size pickup production, ramping up to at least 80 percent by model year 2021. Strong hybrid pickup trucks (at least 65 percent of braking energy is recaptured) would be eligible for a credit of 20 grams of CO2e per mile per vehicle during model years 2017 to 2025 as long as the technology is used in at least 10 percent of the company's full-size pickup trucks.

Innovative financing program helps South Carolina homeowners save money through energy efficiency retrofits

Promoted in Energy Efficiency section:

An innovative energy-financing program has helped customers of South Carolina rural electric cooperatives to undertake energy efficiency retrofits for their homes, substantially reducing their energy use and saving money. 

Through on-bill financing (OBF), customers pay back the cost of the retrofit through monthly installments on their electricity bill. This strategy helps to expand access to costly energy retrofits to low-income residents and makes the financial benefits immediately apparent. If monthly energy savings are greater than or equal to the loan repayment, then OBF will be “bill neutral” and result in the same or lower monthly electricity bills . In addition, the financial obligation of OBF is tied to the electricity meter of each house and can be passed on to subsequent owners and residents; thus, customers only pay for the energy retrofits for as long as they live there. 

A preliminary review of South Carolina’s pilot program, called “Help my House,” found that the 125 participating households are projected to save an average of $400 each year after loan repayments. Energy use could be reduced by thirty-five percent, or approximately 11,000 kilowatt-hours each year. The retrofits, which included improvements to insulation, sealing, and heating, ventilation, and air-conditioning (HVAC) systems, cost an average of $7,200, with projected simple payback periods of 5.86 years. In addition, ninety-six percent of participants reported satisfaction with the efficiency installations and rated their homes as more comfortable after the retrofit.

The program was launched in 2011 by the Central Electric Power Cooperative, which supplies wholesale electricity to 20 rural South Carolina electric cooperatives, and the Electric Cooperatives of South Carolina, the co-ops’ marketing and policy partner, with support from the Environmental and Energy Study Institute. A full-scale OBF energy-efficiency program implemented by South Carolina cooperatives could save an estimated $270 million per year in electricity costs and create more than 7,000 jobs after 20 years, according to an analysis by Coastal Carolina University.

South Carolina utilities were authorized to offer OBF through the passage of Senate Bill 1096 in 2010. The bill eliminated the need for credit checks by tying the financial obligation to the meter rather than to the individual borrower, and allowed utilities to disconnect power if loan repayments are not made. Utilities in 22 other states offer OBF, with supporting state legislation in Illinois, Hawaii, Oregon, California, Kentucky, Georgia, Michigan, and New York.

In addition, “Help my House” was funded by a $740,000 loan from the U.S. Department of Agriculture’s (USDA) Rural Utility Service (RUS), which supports the development of electric, water, and telecommunications services in rural regions. This was the first time RUS funded an energy efficiency initiative, but more cooperatives around the country may follow South Carolina’s example. On July 17 USDA proposed a rule that would create a new RUS program to provide up to $250 million in loans for energy efficiency improvements. The proposed Energy Efficiency and Conservation Loan Program would allow rural electric cooperatives to provide energy efficiency retrofits, including those funded by OBF programs, audits, renewable energy systems, and more.

Business and government start preparing for climate impacts

Today’s Senate hearing isn’t just about the science of climate change. It’s also about the actions that need to be taken now to adapt to the reality of a changing climate. Businesses and governments each have a critical role to play in building resilient communities and economies.

Business-as-usual is already being interrupted by extreme heat, historic drought, record-setting wildfires, and flooding. Events from water shortages to floods are disrupting the supply chains for such companies as Honda, Toyota, Kraft, Nestle and MillerCoors. By the end of 2011, the United States had recorded more billion-dollar disasters than it did during all of the 1980s, totaling about $55 billion in losses.

New York adopts regulations limiting power plant carbon emissions

Promoted in Energy Efficiency section:

On June 28, 2012, New York State finalized its rule limiting carbon dioxide emissions from new power plants, and capacity additions to existing plants, within the state. The rule, 6 NYCRR Part 251, would effectively prevent the construction of new coal-fired power plants unless they are combined with carbon capture and sequestration technology. The new state standard is stricter than the federal rule proposed by the U.S. Environmental Protection Agency in April 2012. The regulation takes effect July 12, 2012.

Please see our original news story for the details of the regulatory standard.
