This guide, commissioned by the Estonian Ministry of the Environment and prepared by the Stockholm Environment Institute Tallinn Centre, provides a methodological framework for organisations in Estonia to calculate their corporate greenhouse gas (GHG) footprint. It is based on international standards, primarily the GHG Protocol and ISO 14064, and includes a specific database of emission factors developed for the Estonian context.

This guide describes the Stock Turnover Analysis methodology within the LEAP software, detailing how to model energy consumption and emissions for both the transport sector and other energy-using technologies based on device lifetimes and vintage-based averages.

The Technology and Environmental Database (TED), integrated within LEAP, provides comprehensive quantitative data on the technical characteristics, costs, and environmental impacts of approximately one thousand energy technologies to support analysts, particularly those in developing countries.

This guide details the greenhouse gas (GHG) inventory methodology used by the World Resources Institute (WRI), covering the reporting period from Fiscal Year 2010 to 2021. It outlines the organizational boundaries, operational scopes, and specific calculation methods for direct and indirect emissions in accordance with the GHG Protocol Corporate Accounting and Reporting Standards.

This working paper addresses widespread errors in the emission factors used for accounting for indirect greenhouse gas emissions from purchased electricity in China. It notes that incorrect factors used in 2010 could lead to a 49 percent over-estimation of emissions and warns that such inaccuracies distort signals for GHG mitigation decisions. Drawing on the GHG Protocol and ISO 14064-1:2006, the paper provides detailed calculation processes and default emission factors for China's regional grids to guide policy makers and corporate users.
