The combustion of coal, oil, and natural gas releases large amounts of carbon dioxide (CO2) and other greenhouse gases.
Cutting down forests reduces the number of trees that can absorb CO2, increasing atmospheric carbon levels.
Manufacturing and industrial processes emit various greenhouse gases, including CO2, methane (CH4), and nitrous oxide (N2O).
Agricultural practices, especially livestock farming, produce methane and nitrous oxide, potent greenhouse gases.
Landfills and waste treatment plants emit methane and other greenhouse gases as organic waste decomposes.
Cars, trucks, airplanes, and ships burn fossil fuels, producing CO2 and other greenhouse gases.
The development of urban areas increases energy consumption and alters land use, contributing to greenhouse gas emissions.
Burning fossil fuels for electricity and heat is a major source of CO2 emissions.
The production of chemicals, including refrigerants and solvents, releases greenhouse gases and other pollutants.
Cement manufacturing emits large amounts of CO2, both from the combustion of fossil fuels and the chemical process itself.
