Greenhouse gas emissions are often classified in 3 scopes, which roughly correspond to how “direct” the emission is, or how close is the actual source emitting the gas.
- Scope 1 are the direct emissions from combustion of fuel and direct use of
- Scope 2 corresponds to indirect emission from energy usage. This includes any
electricity that was produced from a fossil fuel source.
- Scope 3 is all the other indirect emissions anywhere in the value chain. Those
are often the hardest to count
