The frequency of days with “nuisance flooding,” or flooding that causes road closures, overwhelmed storm drains and other public inconveniences, has increased dramatically in many U.S. coastal cities since the mid-1960s—and the threats are worsening.
HFCs are as much as 12,000 times more potent than carbon dioxide. New HFC-reduction initiatives, combined with existing actions, are expected to cut global greenhouse gases by the equivalent of more than 1 billion metric tons of CO2 by 2025, as much as would be achieved by taking 210 million cars off the road for one year.
Today, the U.S. Environmental Protection Agency proposed its first-ever rules targeting methane emissions from the oil and gas sectors.
WASHINGTON (August 3, 2015)— The Obama administration is expected to announce today historic plans to regulate carbon emissions from existing power plants for the first time. The Clean Power Plan would reduce emissions by an average of 32 percent from 2005 levels by 2030.
A new data visualization reveals that only 10 states are responsible for nearly 50 percent of U.S. greenhouse gas emissions.
The EPA will soon release emissions standards for existing power plants, the single-largest source of U.S. greenhouse gas emissions.
Action from the world's two largest emitters, which together account for 38 percent of global greenhouse gas emissions, should inspire greater climate commitments from other nations.
As Karl Hausker noted in a Congressional testimony, the United States can not only achieve its goal of reducing emissions 26-28 percent by 2025—doing so will actually create economic and quality-of-life benefits.
Large trucks and airplanes account for about one-third of total U.S. transportation emissions. WRI analysis shows that setting strong efficiency standards for these sectors could deliver at least 6 percent of the total reductions the United States needs to meet its goal of reducing total emissions by 26-28 percent below 2005 levels by 2025.
The Obama administration committed to reduce U.S. emissions 26-28 percent below 2005 levels by 2025. A new WRI study reveals how to achieve that target—and go even further—through existing federal policies and state action.
WRI Board member and former Assistant Secretary for Policy at the U.S. Department of Energy Sue Tierney explains why April 16th was a remarkable (and remarkably dull) milestone in electric-industry history.
Putting a price on carbon can be an effective policy to spur innovation, create lasting economic growth, and help the United States achieve its carbon reduction goals.
Handbook offers U.S. policymakers comprehensive guidance on options and key elements of carbon pricing
When the price of carbon-intensive fuels and goods increases, the government takes in new revenues. These funds can lower taxes, reduce the federal deficit and more while curbing climate change.
Today, on Earth Day, President Obama delivered remarks from the Florida Everglades on the impacts of climate change and how the administration is responding.
A bipartisan group of county governments are taking action to protect Florida's coastal communities from sea level rise. Will they inspire greater momentum at the state and federal levels?
米国人が使う「now you’re talking（そうだね）」というあいづちの裏には、「ようやく本気を出したね」という意味が込められている。気候変動対策に本腰を入れるとは、言葉による約束を実行に移すということであり、それも思い切った策でなければならない。
Snow-capped mountain ranges no longer have snow. Citizens fear they'll lose access to water. And farmers continue to draw scarce groundwater.
So what can California do to shore up its dwindling water supply?
Climate change is an area where the United States needs to lead, says former Governor of New Mexico and WRI Board member Bill Richardson. Doing so will create a better planet for our children and a more prosperous future for our country.
The new US commitment to tackling climate change is a serious and achievable plan. The country will double its rate of emissions cuts between 2020 and 2025, reducing emissions 26 to 28 percent below 2005 levels by 2025.
