# Carbon Footprint The carbon footprint is the measure of the damage caused by human activities to the environment in terms of the amount of greenhouse gases produced, measured in units of carbon dioxide, and consists of two main parts: a direct (primary) footprint and an indirect (secondary) footprint. The primary footprint is a measure of direct CO2 emissions from the combustion of fossil fuels, including domestic energy consumption and transportation (for example, cars and airplanes), while the secondary footprint is a measure of indirect CO2 emissions from the entire life cycle of the products we use, related to their manufacture and eventual degradation. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question. Perform an HTTP GET request on the current page URL with the `ask` query parameter: ``` GET https://en.wp.mfet.earth/whitepaper/carbon-footprint.md?ask= ``` The question should be specific, self-contained, and written in natural language. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.
