- Emission factors: where they come from and how to choose oneWhat an emission factor is, where the values come from (IPCC, national sources, suppliers) and how to choose the right one for gas, electricity and heat. With a worked example.Basic
- Greenhouse gases and CO₂ equivalent: how GWP worksWhat CO₂ equivalent and global warming potential (GWP) are, which values AR5 and AR6 give for methane and nitrous oxide, and how to convert emissions into t CO₂e.Basic
- Scope 1, 2 and 3: how an organization's emissions are dividedHow Scope 1, 2 and 3 differ under the GHG Protocol: direct emissions, purchased energy and the value chain. Example sources and an emissions calculation for each scope.Basic
