Correct Answer: The total amount of carbon dioxide emitted by a person, organization, or activity

Solution : The correct answer is (A) The total amount of carbon dioxide emitted by a person, organization, or activity

The concept of "carbon footprint" refers to the total amount of greenhouse gases, primarily carbon dioxide (CO2), emitted directly or indirectly as a result of human activities. It is a measure of the impact of these activities on the climate and is usually expressed in terms of CO2 equivalent.

Carbon footprints are calculated by considering the emissions from various sources such as burning fossil fuels for electricity, transportation, industrial processes, and the consumption of goods and services. It takes into account both direct emissions (such as burning fuel in a vehicle) and indirect emissions (such as the emissions generated in the production and transportation of goods).

The concept of carbon footprint is important in understanding and addressing climate change. By measuring and reducing carbon footprints, individuals, organizations, and governments can take steps to mitigate their impact on the environment and work towards a more sustainable and low-carbon future.
