Emissions may be tracked over long time periods, known as historical or cumulative emissions measurements. Cumulative emissions provide some indicators of what is responsible for greenhouse gas atmospheric concentration build-up. See more Greenhouse gas emissions from human activities strengthen the greenhouse effect, contributing to climate change. Most is carbon dioxide from burning fossil fuels: coal, oil, and natural gas. The largest emitters See more Since about 1750, human activity has increased the concentration of carbon dioxide and other greenhouse gases. As of 2024, measured … See more Carbon dioxide (CO2) is the dominant emitted greenhouse gas, while methane (CH4) emissions almost have the same short-term impact. See more The responsibility for anthropogenic climate change differs substantially among individuals, e.g. between groups or cohorts. Generational See more Global greenhouse gas emissions are about 50 Gt per year (6.6t per person ) and for 2024 have been estimated at 57 Gt CO2 eq … See more Relative CO2 emission from various fuels One liter of gasoline, when used as a fuel, produces 2.32 kg (about 1300 liters or 1.3 cubic meters) of carbon dioxide, a greenhouse gas. … See more Global greenhouse gas emissions can be attributed to different sectors of the economy. This provides a picture of the varying contributions of different types of economic activity to climate change, and helps in understanding the changes required to See more WebCombustion, or burning, is a high-temperature exothermic redox chemical reaction between a fuel (the reductant) and an oxidant, usually atmospheric oxygen, that produces …
