The 2020 National Greenhouse Accounts (NGA) Factors publication is now available. These provide methods to help companies and individuals estimate greenhouse gas emissions.
The emission factors in this issue replace those in the NGA Factors we released in August 2019. We’ve updated them to include the latest amendments to method practices for National Greenhouse and Energy Reporting. They also reflect global warming potentials in the Intergovernmental Panel on Climate Change (IPCC) Fifth assessment report. We will use these global warming potentials as the basis for reporting against our Paris Agreement commitments.
