Environment and Climate Change Canada

The Government of Canada's Fuel Life Cycle Assessment Model (the Model) is a tool to calculate the life cycle carbon intensity (CI) of fuels and energy sources used and produced in Canada. The Model is used to determine the CI of hydrogen for the purpose of creating tax credits under the Clean...

We publish Canada’s greenhouse gas (GHG) and air pollutant emissions projections each year. The GHG emissions projections help us measure progress in reducing greenhouse gas emissions and combating climate change. GHG emissions projections are presented for a few scenarios. The air pollutant...

The Canadian Environmental Sustainability Indicators (CESI) program provides data and information to track Canada's performance on key environmental sustainability issues. The Ability of the agricultural landscape to support wildlife indicator maps the relative value of Canada's agricultural...

The purpose of this page is to describe the organization of the greenhouse gas inventory report and to indicate where to find the online material. To learn more about Canada’s official greenhouse gas inventory, visit the Main page: https://www.canada.ca/ghg-inventory Contact us:...

This project examined the effects of pesticides and agricultural practices on parasites of juvenile leopard frogs, Lithobates pipiens (formerly known as Rana pipiens) in southwestern Quebec, Canada. Nine wetlands and two reference sites were sampled in 2004 and 2005, all of which were in various...

Numerous actions have been undertaken by farmers to attenuate the impact of agricultural activities on aquatic ecosystems. The identification of biomarkers that respond quickly to water quality improvement could facilitate the assessment of adopted alternative practices and help maintain...

The Government of Canada’s Fuel Life Cycle Assessment (LCA) Model is a tool to calculate the life cycle carbon intensity (CI) of fuels and energy sources used and produced in Canada.
