Greenhouse Gas Emissions Quantification Guide

The Greenhouse Gas (GHG) Emissions Quantification Guide (PDF, 4,2 MB) presents the methodologies for measuring greenhouse gas (GHG) emissions in sectors affected by climate change. It also includes a section on GHG emission mitigation measures and their monitoring.

The guide is designed for businesses, consultants, government and municipal stakeholders, as well as professionals responsible for quantifying GHG emissions attributable to a given activity. It covers multiple sectors, including transportation, industry, buildings, waste, and agriculture.

Based on a comprehensive review of methodologies developed by recognized organizations in the field, including the Intergovernmental Panel on Climate Change (IPCC)1, this guide consolidates, in a single document, the methods and references that assist users in their quantification work. Additionally, it provides methodologies applicable in various contexts, such as:

  • The development of programs and measures for reducing GHG emissions;
  • Grant applications (e.g., municipal or provincial programs, federal agreements);
  • The reporting, validation, and verification of GHG emissions for projects.

Note to the reader:

In the context of applying the Regulation respecting mandatory reporting of certain emissions of contaminants into the atmosphere (RMRCECA) and the Regulation respecting a cap-and-trade system for greenhouse gas emission allowances (RSPEDE), regulated methodologies take precedence.
