Global net anthropogenic greenhouse gas emissions 1990–2019. Global net anthropogenic greenhouse gas emissions include carbon dioxide from fossil fuel combustion and industrial processes, net carbon dioxide from land use, land use change and forestry, methane, nitrous oxide, and fluorinated gases.

Fossil fuel combustion produces carbon dioxide (CO2), the most abundant global warming pollutant, but also produces local pollutants such as fine particulate matter (PM2.5), nitrogen oxides (NOx), carbon monoxide (CO) and volatile organic compounds (VOCs). which is formed in the atmosphere from precursor gases such as NOx.

Carbon dioxide (CO 2 ) is the most important greenhouse gas that we have added to the atmosphere, however, some of it has been absorbed by land and oceans. In addition, ozone depletion higher up in the stratosphere has caused a cooling high up in the atmosphere. The current estimate is 3°C, with a likely range of 2.5°C

For some parts of the spectrum, the IR can be either absorbed by CO 2 or by water vapour or by clouds, but taking those overlaps into account we find that 50% of the greenhouse effect is from water vapour, 25% from clouds, and about 20% from CO 2 and the rest absorbed by ozone, aerosols, and other trace gases ( Schmidt et al, 2010 ).

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. NO x also contributes to the formation of ozone (or “smog”), another toxic pollutant.

But in reality the proposed emission targets were achieved 11 years early in 2019—without the plan ever even taking effect. Research has shown that the country’s remaining coal plants are responsible for 3,800 premature deaths per year, based on 2019 data.

Transportation generates 47 percent of nitrogen oxide and 21 percent of carbon dioxide emissions in Pennsylvania. “DEP is committed to supporting this choice by increasing public knowledge of electric vehicles, making it easier for consumers to find electric models, and helping to expand charging infrastructure.”
