Detailed explanation-1: -A carbon footprint is the total amount of greenhouse gases (including carbon dioxide and methane) that are generated by our actions. The average carbon footprint for a person in the United States is 16 tons, one of the highest rates in the world. Globally, the average carbon footprint is closer to 4 tons.
Detailed explanation-2: -The carbon footprint of a product is the total amount of carbon dioxide (and other greenhouse gases) which are emitted over the full life cycle of a product, service or event.
Detailed explanation-3: -Notes. CO2 accounts for about 76 percent of total greenhouse gas emissions. Methane, primarily from agriculture, contributes 16 percent of greenhouse gas emissions and nitrous oxide, mostly from industry and agriculture, contributes 6 percent to global emissions. All figures here are expressed in CO2-equivalents.
Detailed explanation-4: -Greenhouse gases are measured in ‘carbon dioxide-equivalents’ (CO2e). Today, we collectively emit around 50 billion tonnes of CO2e each year.
Detailed explanation-5: -When talking about climate change, footprint is a metaphor for the total impact that something has. And carbon is a shorthand for all the different greenhouse gases that contribue to global warming.
