Compared to command-and-control regulations, carbon pricing is a market-based mechanism that creates financial incentives to reduce greenhouse gas (GHG) emissions. Thirteen states that are home to over a 30 percent of the U.S. population and account for more than 36 percent of U.S. gross domestic product have active carbon-pricing programs and are successfully reducing emissions. […]

Twenty-five states and the District of Columbia require electric utilities to deliver a certain amount of electricity from renewable or other clean electricity sources. Eleven states have requirements or goals that have expired, have not been re-upped, or have been repealed. Most of these requirements take the form of either: a renewable portfolio standard (RPS) […]
A greenhouse gas (GHG) emissions target is a state-level goal to reduce emissions by a specific amount by a pre-determined date. The targets can cover all greenhouse gas emissions or specific gases (e.g., carbon dioxide only). The targets can be economy-wide or sector-specific, and they can also differ based on the baseline year that the […]
Forty-eight states and the District of Columbia have developed either a state climate action plan, a Priority Climate Action Plan (under the EPA’s Climate Pollution Reduction Grants program), or both. 32 states and the District of Columbia have released a state climate action plan, while 16 states have released only a Priority Climate Action Plan. […]

With more than 40 percent of the global capacity of carbon management projects (13 in operation and more than 60 in different stages of development), the United States is expected to play a major role in the deployment of carbon capture, removal, and storage (CCUS) technologies. Carbon capture technologies can be retrofitted to existing industrial […]
The transportation sector became the largest source of U.S. greenhouse gas (GHG) emissions in 2016. Driven by increased travel demand, low fuel prices, and urban sprawl, transportation emissions grew about 23 percent between 1990 to 2019. To change this trajectory, states have utilized several types of alternative vehicle policies including vehicle GHG emissions standards, zero-emission […]
The transportation sector is the largest source of U.S. greenhouse gas emissions. While transportation sector emissions have fallen by 6.1% from their 2005 peak, transportation sector emissions grew about 21.5% from 1990 to 2016, largely driven by increased demand for travel based on economic and population growth, low fuel prices, and urban sprawl. To change […]
