Don’t Believe the Lies: Five Facts to Consider as the UN’s COP27 Comes to a Close

Union of Concerned Scientists

Their study examined the carbon dioxide and methane emissions from these companies’ products, as well as from the extraction and production processes of the largest gas, oil and coal producers and cement manufacturers. Data on the major carbon producers’ emissions have been published since 2014.

Inside the IPCC 61st Plenary Meeting: Debates and Decisions Shaping Climate Policy

Union of Concerned Scientists

Outline of a Methodology Report on Short-Lived Climate Forcers Since 2006, the IPCC has provided methodologies that governments around the world use to estimate their greenhouse gas emissions. The days were long, and results were mixed, but at the end of the week, key decisions were made to move the IPCC process forward.

A 100% Renewable Energy Future is Possible, and We Need It

Union of Concerned Scientists

Sulfur dioxide (SO 2 ) and nitrogen oxides (NO x ) emissions from power plants in USCA states fall 88 and 77 percent respectively by 2040, compared with 27 and 18 percent under current policies and plans. Just as important, cleaning up the power grid can also decrease carbon dioxide (CO 2 ) emissions.

Too Many Gas Power Plants are the Problem Not the Solution

Union of Concerned Scientists

Over the year, those plants emitted 661 million metric tons of carbon dioxide, more than 13% of the US’s energy-related carbon dioxide emissions. But gas plants also release emissions of nitrogen oxides, more commonly referred to as NOx emissions, that contribute to smog and other pollutants.

Fossil Fuels Must Go: Re-inventing US Transportation

Union of Concerned Scientists

Carbon dioxide and methane (a short-lived but extremely powerful global warming gas) are emitted during the extraction, processing, storage, transportation and combustion of gasoline, diesel and other petroleum fuels used by our vehicles. We have over 284 million gasoline- and diesel-burning cars, trucks and buses on our roads.

Good News—and Bad—about Fossil Fuel Power Plants in 2023 

Union of Concerned Scientists

In 2021 alone, the plants slated for retirement emitted more than 28,000 tonnes of nitrogen oxides (NO x ), 32,000 tonnes of sulfur dioxide (SO 2 ), and 51 million tonnes of carbon dioxide (CO 2 ), according to EIA data. What can be done?
