Maryland Officially Joins Regional Greenhouse Gas Initiative, Establishes Climate Commission

Promoted in Energy Efficiency section: 

On April 20, 2007, Governor Martin O’Malley of Maryland signed the Memorandum of Understanding for the Northeast Regional Greenhouse Gas Initiative (RGGI), officially joining his state to the first multi-state greenhouse gas emissions cap-and-trade program in the U.S. Other participants include Connecticut, Delaware, Maine, Massachusetts, New Jersey, New Hampshire, New York, Rhode Island, and Vermont. As members of RGGI, states agree to a regional cap-and-trade program covering power plant carbon dioxide emissions. RGGI aims to cap these emissions at approximately current levels between 2009 and 2015, and then reduce this level 10% by 2019.

On the same day, Governor O’Malley signed an executive order establishing a Maryland Climate Change Commission that will create a state action plan to address climate change. The Commission will assess the possible impacts of climate change; calculate Maryland’s contribution to the climate change problem; work together with various state agencies, energy providers, business leaders, and other groups to develop a greenhouse gas reduction strategy; and develop a plan for reducing the state’s vulnerability to sea level rise and other effects of climate change.

State Legislation from Around the Country

The following are examples of both enacted and introduced climate change legislation from around the country.

Economy-Wide Greenhouse Gas Reductions

This type of legislation establishes an economy-wide emissions target for the entire state.

State Climate Change Commissions

Executive or legislative commissions examine the possible consequences of climate change for a state and the costs and benefits associated with addressing them, and develop recommendations for appropriate policies.

Climate Action Plans

Often building on the work of their commissions, states design climate action plans tailored to their specific circumstances, seeking the most effective way to address climate change.

Greenhouse Gas Reporting

Several states have begun implementing either mandatory or voluntary reporting of greenhouse gas emissions from major sources. The Climate Registry is a non-profit organization that aims to measure and publicly report greenhouse gas emissions in a common, accurate, and transparent manner consistent across industry sectors and borders.

Greenhouse Gas Performance Standards for Electric Power

These requirements ensure that all electricity used in a state is produced with certain greenhouse gas emissions standards.

Greenhouse Gas Performance Standards for Vehicles

By law states have the option of either following federal emissions standards for cars and light trucks or following California's standards. Other states that have already adopted or are in the process of adopting the California standard include Arizona, Connecticut, Maine, Maryland, Massachusetts, New Jersey, New York, Oregon, Pennsylvania, Rhode Island, Vermont, and Washington.

Emissions Reductions in the Transportation Sector

In many states, transportation is a major contributor to greenhouse gas emissions. Some states have enacted laws that aim to reduce vehicle miles traveled (VMT) in the future.

Capturing the Emerging Market for Climate-Friendly Technologies: Opportunities for Ohio

Capturing the Emerging Market for Climate-Friendly Technologies: Opportunities for Ohio

Prepared by the Pew Center on Global Climate Change
November 2006

Executive Summary

Increasing certainty that humans are changing the earth’s climate through emissions of greenhouse gases is creating a new market for climate-friendly products and services. As states and nations begin to address climate change by regulating greenhouse gas emissions and encouraging the use of clean energy, demand is growing for technologies such as wind power, biofuels, and cleaner coal power plants. Ohio’s manufacturing and agriculture sectors are already providing some of these solutions, and the state’s economy stands to benefit as a supplier of the technologies and strategies to tackle climate change. This paper briefly describes the factors driving the growing demand for climate-friendly technologies, some of the key existing companies, organizations, and resources in Ohio, and the potential for Ohio to become a leading supplier of climate solutions. These solutions include a new generation of lower-emitting coal technologies, components for wind turbines, and the feedstocks and facilities to produce biofuels. The paper concludes with recommendations for how Ohio can capitalize on these emerging opportunities. These recommendations include focusing and coordinating state funding of climate technology programs, promoting the development of climate-related industry clusters, and exploring export opportunities to states and countries with existing carbon constraints.

Boulder Passes Tax on Greenhouse Gas Emissions from Electricity Generation

Promoted in Energy Efficiency section: 

On November 8, 2006, voters in Boulder, Colorado, passed the first energy tax in the nation designed to fund efforts to fight global warming. This Climate Action Plan Tax on greenhouse gas emissions-generating electricity is collected by the local electric utility based on the amount of electricity used by customers. The tax only applies to electricity generated from the combustion of carbon-emitting fossil fuels such as coal and natural gas; customers signed up through a voluntary program to receive some or all of their electricity from wind power will be exempt from the tax for the carbon-free share of their electricity use. On average, the tax will add about $1.33 per month to household electricity bills, and $3.80 per month for businesses. The collected revenue, estimated to be about $1 million a year through 2012, will be used by Boulder’s Office of Environmental Affairs to help the city meet the goals set under its 2006 Climate Action Plan, which include investment in renewable energy sources, energy efficiency for buildings, and transportation initiatives. The city’s plan aims to reduce greenhouse gas emissions seven percent below 1990 levels by 2012.
