GEOLOGY

Detailed explanation-1: -In his book, Berners-Lee writes that the average global citizen has a carbon footprint that is equivalent to the emission of seven tons of carbon dioxide per year.

Detailed explanation-2: -Everyone’s carbon footprint is different depending on their location, habits, and personal choices. For an explanation of the calculator’s assumptions and sources, see the Assumptions and References page.

Detailed explanation-3: -Credit: NASA/JPL-Caltech. All living things on Earth contain carbon. Even you contain carbon.

Detailed explanation-4: -Because it would be prohibitively expensive or disruptive to eliminate some sources of emissions entirely, achieving net-zero emissions is considered more feasible than achieving zero emissions at a nationwide scale. Many governments and businesses have set a goal of achieving net-zero emissions by 2050.

Detailed explanation-5: -Unfortunately, most things leave a carbon footprint. Activities such as production, transportation, and decomposition can emit carbon into the atmosphere. In total, all carbon emissions make up 76% of all greenhouse gases globally.
