GHG Protocol
About GHG Protocol
The GHG Protocol is the de-facto standard-setting organisation for greenhouse-gas accounting. As well as producing guidance on estimating and categorising emissions, it also provides a set of the most commonly-used emission factors including energy consumption, transportation, waste management, and industrial processes.
