What is a Carbon Footprint?
Definition of carbon footprint
A carbon footprint is the total amount of greenhouse gases, primarily carbon dioxide (CO2), released into the atmosphere as a result of human activities. It represents the impact an individual, organization, or industry has on the climate and the environment. Carbon footprints are often measured in units of carbon dioxide equivalent (CO2e) and can be used to assess and compare the environmental impact of different activities.
Explanation of greenhouse gases
Greenhouse gases (GHGs) are gases that trap heat in the Earth’s atmosphere, leading to the greenhouse effect and resulting in global warming. These gases contribute to the warming of the planet by absorbing and emitting thermal radiation. The primary greenhouse gases include carbon dioxide (CO2), methane (CH4), nitrous oxide (N2O), and fluorinated gases. CO2 is the most prevalent greenhouse gas released through human activities, while methane and nitrous oxide have higher global warming potential.
Different types of carbon footprints
Carbon footprints can be categorized into three main types: primary, secondary, and tertiary. Primary footprints refer to the direct emissions produced by an individual, organization, or industry. These emissions result from activities such as burning fossil fuels for heating or transportation. Secondary footprints include indirect emissions that are generated throughout the supply chain of products and services. Tertiary footprints are associated with carbon emissions from land-use changes and deforestation.
Calculating Carbon Footprints
