The total greenhouse gas emissions associated with a person, activity or product, usually expressed as carbon dioxide equivalent.

The total greenhouse gas emissions associated with a product, activity or person. For food, this includes production, packaging and transport.

However, transport is only one part of a food’s carbon footprint. Emissions also arise during production: livestock, especially cattle, release methane. Packaging machinery uses energy, which may come from burning fossil fuels.

The total greenhouse gas emissions associated with a person, activity or product, including indirect emissions from producing goods and services, usually expressed as carbon dioxide equivalent.

Food miles measure distance, not the whole carbon footprint. Growing, packaging and transporting food all contribute emissions.

Check what a footprint includes before comparing results: household energy emissions alone are not a complete household carbon footprint.

The total greenhouse-gas emissions associated with a person, population, organisation or activity, expressed as carbon dioxide equivalent.

A carbon footprint measures greenhouse-gas emissions. It is usually expressed in kilograms or tonnes of carbon dioxide equivalent, written kg CO₂e or t CO₂e. Carbon dioxide equivalent combines different greenhouse gases into a common measure of their warming effect.

A carbon footprint includes greenhouse gas emissions associated with an activity or product. Equipment manufacture and fuel production can create emissions even where electricity generation itself involves no fossil fuel burning.

The total greenhouse-gas emissions associated with a person, population, organisation, activity or product, expressed as a mass of carbon dioxide equivalent, usually kilograms or tonnes of CO₂e.
