On EPA dropping sponsorship of Climate Leadership Awards, Conference

We were disappointed to learn today that EPA will no longer co-sponsor the annual Climate Leadership Awards and Climate Leadership Conference. We thank EPA for the unique and vital role it has played over the past seven years in supporting the awards and conference.

In light of EPA’s decision, the awards and conference co-sponsors -- the Center for Climate and Energy Solutions (C2ES) and The Climate Registry (TCR) – will be stepping up to ensure both events continue to thrive.

Since 2012, more than 115 recipients have been recognized for leadership in addressing climate change by reducing carbon emissions in their internal operations and supply chains, and planning for climate impacts.

The Climate Leadership Conference and awards, drawing hundreds of sustainability professionals from across the country, will go forward in Denver, Colorado, on February 28-March 2, 2018.

We believe it’s more important than ever to encourage and recognize climate action by businesses, organizations, local governments, and individuals to reduce the man-made emissions that are causing our climate to change. We’re eager for opportunities to build new partnerships to ensure the 2018 Climate Leadership Conference and Awards are better than ever.

On July 26, 2017, California Governor Jerry Brown signed into law a bipartisan bill that extends the state’s cap-and-trade program to 2030. Cap and trade is a key part of California’s plan to reduce greenhouse gas emissions 40 percent below 1990 levels by 2030. The enacted bill makes design changes to the post-2020 carbon market, such as including a price ceiling, price containment points, additional limits to the number and location of offset credits, limits on who can set greenhouse gas emission requirements, and specifics on industry assistance factors. This document summarizes these program changes.

New research highlights flood risks from sea-level rise

Recent scientific studies on the impacts of sea-level rise can help cities and businesses in coastal areas strengthen their climate resilience planning.  

Coastal flooding is expected to be a particularly costly climate impact. As the seas rise, U.S. cities from Miami to Atlantic City, New Jersey, now routinely deal with tidal flooding, also called nuisance flooding or sunny day flooding. But higher sea levels can also magnify flooding from more rare major storms like hurricanes.

Researchers at Princeton and Rutgers recently took into account the fact that coastal cities face this combination of small (high-probability) and large (low-probability) flooding events. They took observations from the National Oceanic and Atmospheric Administration’s (NOAA) tide gauges and used statistical techniques to measure the occurrence of historically low- and high-probability events across coastal locations. They then used sea-level rise projections to understand how the frequency of low- and high-probability events would change at each location.

The key insight from this study is that sea-level rise will have a different impact on flooding patterns in different regions of the country. Charleston, South Carolina, will see a larger increase in moderate floods than in severe floods (though both types of floods will increase), while Seattle will see the opposite pattern.

The study also demonstrates that flood frequencies will increase dramatically in many coastal areas by 2050. The blue and green dots in the maps below show the places where flood frequencies will increase by hundreds or even thousands of times from today (Alaska and Hawaii were also modeled in the study, but not shown in this map. The full dataset is here).

It’s no wonder, then, that cities and businesses across the country are taking steps to prepare for flooding and other climate change risks. We continue to urge them to work together to find the options that work best for the community overall. 

A year after a devastating flood, lessons in building resilience

Nearly one year after a devastating flood in Ellicott City, Maryland, shoppers pass by reopened businesses and shuttered ones in the same block of historic Main Street.

Nearly a year after a devastating flood, business is bustling again along Main Street in Ellicott City, Maryland, but signs of the disaster remain. Just steps away from shops with flags flying and doors open are others with “space available” signs and boarded-up windows. Construction equipment sits at the corner.

Climate change is increasing the odds that communities across the United States will face similar risks. To withstand these disasters, communities must become more resilient, and a C2ES report offers ways for state and local governments to help.

On July 30, 2016, more than six inches of rain fell in two hours in a low-lying area in central Maryland bounded by two rivers. Water gushed down a historic Ellicott City street lined with antique shops, art galleries, boutiques, and restaurants. The flood damaged 90 businesses and caused more than $22 million in damages to infrastructure.

The economic damage didn’t stop there. The county where Ellicott City is located lost between $42 million and $67 million in economic activity and as much as $1.3 million in tax revenues because of the flood.

With the help of loans from the state and private donations, more than 90 percent of the damaged businesses have reopened, and some new ones are moving in.

The National Weather Service classified the storm as a thousand-year rainfall event – meaning that scientists using historic data calculate a one-in-a-thousand chance of an event like this occurring each year. But as the climate keeps changing, the odds of seeing extreme weather go up, increasing the risks to communities and businesses throughout the country.

Almost 40 percent of small businesses nationwide never reopen their doors following a disaster event. Those closings can have an especially big impact; small businesses account for more than half of U.S. sales and jobs.

Small business owners often are unaware of their climate risks and lack the time and resources to prepare for the impacts. Fewer than half of Maryland small businesses that replied to a C2ES survey said they knew about climate risks. Most said they lacked resources to learn about them, and that available resources do not directly address local risks most relevant to them.

But state and local governments in Maryland and elsewhere can help their small businesses become more climate-resilient by following the recommendations in C2ES’s framework for engagement.

When engaging with small businesses on weather and climate resilience, the C2ES framework recommends state and local officials:

1.    Use trusted messengers to convey climate information. These include organizations that small businesses frequently interact with, like city or county chambers of commerce, trade associations, and other business organizations.

2.    Leverage existing channels of communication. State agencies and local agencies often already interact with businesses on preparedness, emergency planning, flood management, long-term planning, and economic development. Climate resilience information can be incorporated into these interactions. Likewise, existing resilience efforts can be broadened to include the business community.

3.    Identify new opportunities. New programs and information can be developed on small business resilience, such as public-private partnerships and business resilience networks. Training materials and other resources can be distributed via trusted messengers.

4.    Distribute targeted information. Businesses need more information on what they can realistically do to become more resilient to extreme weather and climate change. Sector- and location-specific information can help businesses better understand their risks and opportunities for enhancing resilience. 

The extreme weather risk to communities like Ellicott City will only increase as the Earth’s atmosphere continues to warm from rising greenhouse gas emissions. But state and local governments have opportunities to open new channels of communication to help small businesses become more climate resilient and able to survive disasters.

Bob Perciasepe on the extension of California's cap and trade program

Statement of Bob Perciasepe
President, Center for Climate and Energy Solutions

July 18, 2017

On California’s vote to extend its cap-and-trade program:

California is showing the nation and the world how diverse interests can come together to promote cost-effective climate action.

Cap and trade gives businesses the flexibility to find the least-cost path to reduce emissions. This flexibility promotes innovation that creates new industries and jobs.

California has put hundreds of thousands of people to work in clean energy, while also cutting greenhouse gas emissions 10 percent from their peak in 2004. 

California's program is also specifically designed so that a significant portion of the revenue helps disadvantaged communities. A companion bill addresses community air quality concerns by increasing monitoring and imposing more stringent penalties on polluters. A guarantee that prices stay below a certain level ensures that Californians don’t pay more than their share for a safer climate while waiting for the rest of the country to catch up on policy action.

Particularly at a time of diminished federal leadership, California's program is a model for the rest of the country and the world. We applaud the governor and state lawmakers for their leadership.

RE: C2ES supports extending CA's cap-and-trade program and AB-398

Dear Governor Brown, President Pro Tempore de León, and Speaker Rendon:

As a climate focused think-tank, C2ES has a long history supporting market-based policies to address climate change. We congratulate you on the introduction of AB-398, which extends California’s precedent-setting cap-and-trade program. We believe this bill, along with the companion bill AB-617, demonstrate  how to address both the climate challenge beyond 2020 and local air quality concerns.

California's steadfast determination to address climate change is a model for the country, as is its well-designed cap-and-trade program. Cap and trade ensures that the state's aggressive goals are met cost effectively. Failure to extend the program would send a signal across the U.S. and globally that this type of program does not work, which would be false.

Cap and trade ensures that the state’s aggressive reduction target will be met. It also provides an incentive to invest in low-carbon technology, drives innovation, creates jobs and generates revenue. How to use any revenue is always contentious, but AB-398 lays out options that will help reduce greenhouse gas emissions and other types of pollution and ensure that vulnerable populations are protected.  

California has demonstrated that an economy-wide cap-and-trade program can work. You are once again showing the world how progress toward a low-carbon future is possible. We strongly support a yes vote on this bill.

Strengthening Energy Efficiency Programs for Low-Income Communities

Strengthening Energy Efficiency Programs for Low-Income Communities

July 2017

Download (PDF)

Energy efficiency programs offer an effective way to reduce energy consumption and address energy burden. These programs are particularly beneficial to low-income households, which spend a higher percentage of their income on energy bills. There are many energy efficiency programs offered by states, cities, and utility companies, but often only a subset of these programs is specifically designed for and directly benefits low-income communities. This fact sheet provides an overview of how energy efficiency programs could benefit low-income communities, and how to design efficiency programs to better serve low-income communities.

America’s Pledge can drive and tally U.S. climate action

Today, Gov. Jerry Brown and Michael Bloomberg are launching America’s Pledge—an initiative to compile and quantify the actions of U.S. states, cities and businesses to drive down their greenhouse gas emissions consistent with the goals of the Paris Agreement.

America’s Pledge will for the first time aggregate and quantify the commitments of these “non-state actors,” demonstrating to the international community that U.S. climate resolve remains strong despite President Trump’s decision to withdraw from Paris.

The ambitious initiative also will provide a roadmap for increased ambition, outlining steps these groups can take to further reduce their emissions.

Since the president’s announcement, an unprecedented number of U.S. states, cities, and businesses have affirmed their support for the landmark climate deal, including through the “We Are Still In” declaration signed by more than 1,500 businesses, nearly 200 cities and counties, nine states, and over 300 universities. 

This enthusiasm for climate action is as yet unquantified, but it’s vast and varied and growing every day:

  • Just this week, California Gov. Jerry Brown and legislative leaders released a plan to extend through 2030 California’s cap-and-trade program. The program marshals market forces to motivate investment in low-carbon solutions, drive innovation, create jobs, and cut emissions cost-effectively.
  • Also this week, Colorado announced it will be the 14th state in the newly formed U.S. Climate Alliance, whose members together represent over a third of the U.S. population and GDP. The states are committed to the U.S. meeting its Paris target of reducing emissions 26 to 28 percent from 2005 levels by 2025.
  • More than 350 Climate Mayors have adopted the Paris Agreement goals for their cities. And more than 100 U.S. cities both large and small have pledged to transition their communities to 100% clean energy.
  • About two-thirds or more of mayors who responded to a recent survey by C2ES and The U.S. Conference of Mayors said they generate or buy renewable electricity to power city buildings or operations, buy green vehicles for municipal fleets, and have energy efficiency policies for municipal buildings. And they want to partner with the private sector do more.
