What does it all mean?!
The climate space is full of jargon, acronyms, and buzzwords.
Here’s your friendly, no-nonsense guide to what it all means.
-
Carbon Footprint: The total amount of greenhouse gases (GHGs), especially carbon dioxide (CO₂), emitted directly or indirectly by an individual, organization, event, or product.
-
Carbon Offset: A reduction in emissions of carbon dioxide or other GHGs made in order to compensate for emissions made elsewhere.
-
Greenhouse Gases (GHGs): Gases that trap heat in the atmosphere. Common GHGs include carbon dioxide (CO₂), methane (CH₄), nitrous oxide (N₂O), and fluorinated gases.
-
Net Zero: Achieving a balance between the amount of GHGs emitted and the amount removed from the atmosphere. Often a target for companies or nations by a specific year.
-
Carbon Neutral: Having a net zero carbon footprint by offsetting emissions with an equivalent amount of carbon removal or offset projects.
-
Sequestration: The process of capturing and storing atmospheric carbon dioxide, either naturally (e.g., in forests or soil) or through technologies like carbon capture and storage (CCS).
-
Baseline Emissions: The projected or historical level of emissions without intervention, used as a reference point for measuring reduction.
-
Additionality: A key principle in carbon offsets requiring that the carbon savings would not have occurred without the offset project.
-
Leakage: When emission reductions in one area result in increased emissions elsewhere.
-
Permanence: The longevity of a carbon offset’s impact; whether the emissions reductions will remain over time without reversal.
