May 1st, 2018 The Climate Registry (TCR) is pleased to present its default emission factors for reporting in 2018. Each year, we update the default emission factors associated with our program because (1) the components of energy (electricity, fuel, etc.) change overtime, and (2) emission factor quantification methods are often refined. The 2018 default emission factors are incorporated into the Climate Registry Information System (CRIS) for use in emissions calculations to ensure that our members are measuring the most accurate greenhouse gas (GHG) data possible.1 We publish these default factors to our website to advance best practices in corporate GHG accounting, and to promote transparency and consistency in that accounting. Our default emission factors are compiled from publicly availlable data sources, which are cited at the bottom of each table. TCR is not responsible for the underlying data or methodology used to calculate these default emission factors, or for communicating any changes to the data sources that occur between our annual updates. As detailed in TCR’s General Reporting Protocol Version 2.1 (GRP v. 2.1), you should apply the mostt up‐ to‐date emission factor available in CRIS (or otherwise) when calculating emissions. Too calculate location‐based or market‐based Scope 2 emissions, you shouuld apply the emission factor most appropriate to the emissions year being reported that does not post‐date that emissions year. TCR members are encouraged to contact
[email protected] with questions or feedback on these default emission factors or citation information. Sincerely, The Climate Registry 1 All new inventories created in CRIS, regardless of emissions year, wwill rely on these emission factors.
