This Greenhouse Gas Emissions (GHG) Quantification Guide (PDF, 3,1 MB) provides an update to a guide of the same name published by the MELCCFP in November 2019.
Its purpose is to present the methodologies used to quantify greenhouse gas (GHG) emissions in sectors affected by climate change. This guide also includes a section about measures for mitigating and tracking GHG emissions. It is based on extensive research into the methodologies developed by recognized organizations in the field, including the Intergovernmental Panel on Climate Change (IPCC)1. This guide is therefore a valuable tool, since it brings together in a single document the methods and references to support clients in their quantification work.
Many clients, including businesses, consultants, government and municipal stakeholders, as well as professionals, may need to quantify GHG emissions from a given activity. This guide is aimed at the transportation, industry, building, waste management, and agriculture sectors. The purpose of this guide is to provide a methodology for:
Due to the evolving understanding of the subject, several new sections have been included in this update regarding loss of carbon sequestration capacity due to deforestation, the role of forests in climate change mitigation, the impacts of GHG emissions on wetland loss, and avoided emissions. Also, several updates have been made to address issues such as emissions from landfills.
Note to the reader:
In the application of 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), (RCATS), the regulated methods take precedence.
