GEOLOGY

Detailed explanation-1: -And if food goes to the landfill and rots, it produces methane-a greenhouse gas even more potent than carbon dioxide. About 6%-8% of all human-caused greenhouse gas emissions could be reduced if we stop wasting food.

Detailed explanation-2: -Production, transportation, and handling of food generate significant Carbon Dioxide (CO2) emissions and when food ends up in landfills, it generates methane, an even more potent greenhouse gas.

Detailed explanation-3: -Greenhouse gas emissions can be reduced by making power on-site with renewables and other climate-friendly energy resources. Examples include rooftop solar panels, solar water heating, small-scale wind generation, fuel cells powered by natural gas or renewable hydrogen, and geothermal energy.

Detailed explanation-4: -Emissions of carbon dioxide, the primary greenhouse gas emitted by human activities, decreased by 8 percent. Methane emissions decreased by 17 percent, as reduced emissions from landfills, coal mines, and natural gas systems more than offset increases in emissions from activities such as livestock production.

Detailed explanation-5: -Solid waste contributes directly to greenhouse gas emissions through the generation of methane from the anaerobic decay of waste in landfills, and the emission of nitrous oxide from our solid waste combustion facilities.
