Cooler Together

America and the world need to take urgent action to reduce the dangers posed by global warming. As the Trump administration steps back from global leadership, states are picking up the torch of climate action. Nine Northeastern and Mid-Atlantic states have pioneered an effective, bipartisan model for cutting carbon pollution from power plants - one that can serve as a model for other states and regions to follow.

Since it began in 2008, the Regional Greenhouse Gas Initiative (RGGI), the nation’s first regional program for limiting carbon dioxide emissions from power plants, has been wildly successful. The program, in place in nine northeastern and mid-Atlantic states, caps power plant emissions, puts a price on carbon pollution, and reinvests much of the revenue into programs that advance the region’s transition from fossil fuels to clean energy.

Now more than ever, state leadership is critical for America to make progress in the fight against global warming. The Regional Greenhouse Gas Initiative shows the way forward – bringing together political leaders of both parties around effective policies to curb carbon pollution and accelerate the transition to clean energy. Leaders in the Northeast and Mid-Atlantic states should continue to support RGGI and other policies to cut carbon pollution, leaders in nearby states should consider joining the program, and leaders from around the country should follow the example of the program when taking their own steps to address global warming.

Regional efforts to cut pollution from power plants have helped move the Northeast and Mid-Atlantic toward a healthier future built on clean energy. Benefits of the Regional Greenhouse Gas Initiative include:

  • Contributing to halving the region’s CO2 ­emissions from electric power plants since 2005, with plans to cut emissions to one-third of 2005 levels by 2030;[i]
  • Providing more than $5.7 billion in health benefits to the region, including averting hundreds of premature deaths;[ii]
  • Raising more than $2.78 billion for member states, including more than $1 billion in investments in energy efficiency improvements and $270 million for clean and renewable energy investments, with the potential to raise more than $7 billion more by 2030;[iii]
  • Saving consumers more than $773 million on their energy bills;[iv]
  • $3 billion in net economic benefits, including the creation of more than 30,000 jobs in the region.[v]

The success of the Regional Greenhouse Gas Initiative shows that aggressive, bipartisan action on climate change is possible, and that it can lead to dramatic progress and broad-based benefits for the region.

Northeastern and Mid-Atlantic states should build on the success of the Regional Greenhouse Gas Initiative by:

  • Continuing to invest in clean energy and adopt complementary policies that make it as easy as possible for individuals, businesses and institutions to reduce energy consumption and switch to clean, renewable sources of energy.
  • Extending the approach used to successfully reduce emissions from power plants to other sectors of the economy, such as transportation.

Other states should consider putting a price on carbon pollution and reinvesting the proceeds in the transition to clean, renewable energy.

  • New Jersey and Virginia will benefit greatly from joining RGGI. Between the two states, joining RGGI could generate as much as $4.2 billion in revenue by 2030 that could speed their transition to clean energy, while reducing as much as 88 million tons of carbon dioxide emissions cumulatively.
  • Other states around the United States should consider adopting similar approaches to reducing greenhouse gas emissions.
