Projects we support:

In accordance with industry standards, we measure greenhouse gas emissions and offsets in "tCO2e". That stands for tonnes of carbon dioxide (CO2) equivalent. Although there are many gases identified as greenhouse gases, each gas has a different global warming potential (GWP), meaning each gas affects the climate at a different intensity. Carbon dioxide is used as the baseline quantity therefore 1 tonne of CO2 is 1 tonne of 1 tCO2e. The GWP of methane though is 23 therefore 1 tonne of methane gas is 23 tCO2e. When we calculate quantities of greenhouse gas emissions to measure and offset, we add the tonnes according to their GWP to get a total of tonnes of carbon dioxide equivalent or tCO2e.

Project Type Project Brief
agricultural methane
Vander Haak Dairy Project
tCO2e sourced: 2,200
Washington, USA
offset quality
Vander Haak Dairy in Washington State was one of the first dairy farms in the U.S. to register carbon credits with the Chicago Climate Exchange. This project began in 2004 and has the capacity to treat and capture methane, a potent greenhouse gas, from about 1,500 milk cows using a GHD plug-flow anaerobic digester. The emission reductions from this process amounts to 560 tonnes of methane per year which is about 10,000 tonnes of CO2 equivalents.
landfill methane
Ferti-Val and Agrior
tCO2e sourced: 2,500
Quebec, Canada
offset quality
These emission reductions are generated by recycling residual waste. With well established infrastructures to deal with both organic and inorganic waste products, they operate and maintain a compost site and a dry sorting centre. They primarily treat bio-solids, which are wastes derived from the treatment of used water. Usually these bio-solids are left to decompose in landfill sites, which cause the material to decay anaerobically emitting methane gas into the atmosphere. The project activity is the implementation of an efficient forced-air platform, which shortens the composting time by 3 or 4 fold and most importantly decreases the generation of methane gas.
tire recycling
Royal Mat Waste Diversion
tCO2e sourced: 2,500
Quebec, Canada
offset quality
This activity reduces greenhouse gas emissions through the transformation of used tires from cars and trucks instead of using newly sourced rubber. The company works hard to preserve the original characteristics of the rubber that it recycles. The company produces rubber carpets and other products from second-hand tires. The company developed an intricate process to shred and granulate old tires, which also includes a heat recovery system that further reduces emissions. The recovered heat is used to dry the granules and is also redistributed in various parts of the manufacturing process.
tree planting
tree canada foundation
tCO2e sourced: 275
across Canada
offset quality
Tree Canada Foundation (TCF) is a charitable organization which partners with local volunteers to improve our quality of life by planting and caring for trees. In your neighborhoods, schoolyards, parks and in the countryside, TCF leaves a living, breathing legacy for generations to come. In 1992 Tree Canada Foundation was originally founded to "encourage tree planting to help reduce the harmful effects of carbon dioxide emissions that contribute to climate change." In 2005, the partnership between cleanairpass and TCF was created to ensure that cleanairpass subscribers are offsetting greenhouse gas emissions right here in Canada while supporting one of Canada's largest tree planting organizations. This is an opt-in choice beyond choosing to offset with cleanairpass. Only members who subscribe through the TCF website are offset by tree planting efforts of TCF.
