According to the IPCC, the anthropogenic greenhouse gas (GHG) emissions contributing most evidently to Global Warming in terms of relative radiative forcing are CO2 , CH4 , halocarbons and N2O. CO2 emissions originate mainly from combustion of fossil fuels, and are quite well-known. However, ...
Food systems contribute one-third of global anthropogenic greenhouse gas (GHG) emissions, roughly 16.5 GtCO2e year−1from a total 54 GtCO2e year−11,2, with both pre- and post-production phases representing a high and increasing share of total emissions3. The Food and Agriculture Organizati...
Since the industrial revolution began, the atmospheric abundance of key greenhouse gases have increased substantially.
A Global Breakdown of Greenhouse Gas Emissions by Sector In a few decades, greenhouse gases (GHGs)—chiefly in the form of CO₂ emissions—have risen at unprecedented rates as a result of global growth and resource consumption. To uncover the major sectors where these emissions originate, this...
According to the United Nations, 60 percent of global greenhouse gas emissions come directly from the way that we currently produce our electricity.71 percent of the earth is covered in water yet only around 1.5 percent of the global energy is produced through wave power. That’s what inspired...
Agriculture and land use are major sources of greenhouse gas (GHG) emissions but previous estimates were either highly aggregate or provided spatial details for subsectors obtained via different methodologies. Using a model–data integration approach that ensures full consistency between subsectors, we ...

The world's population is now over 50% urban, and cities make an important contribution to national greenhouse gas (GHG) emissions. Many cities are developing strategies to reduce their emissions. Here we ask how and why emissions differ between cities. Our study of ten global cities shows how...
The future of our carbon dioxide and greenhouse gas emissions will decide how many degrees will planet Earth be warmer by 2100 (relative to pre-industrial
ByAngie Bergenson Following a sharp decline due to lockdowns to reduce COVID-19 spread, air pollution is rising. Throughout the spring, greenhouse gas emissions plummeted around the world as factories, air traffic, and other forms of transportation ground to a halt due to the pandemic ...
