The Saskatchewan provincial government is planning to implement a carbon credit program that rewards projects for removing greenhouse gases from the atmosphere. Gases will be measured in carbon dioxide equivalent units. The program provides 1 credit for every tonne of carbon dioxide equivalent removed from the atmosphere. Credits can be used to increase emission caps set by the government or sold for money. How the market for credits will be regulated has not been announced.
In Saskatchewan, research has found that a 1 kilometer row of shelterbelt trees can sequester anywhere from 1.7 to 6.5 tonnes of carbon per year. 1 gram of sequestered carbon requires 3.66 grams of CO2. If a tree sequesters the maximum of 6.5 tonnes of carbon it will have used approximately 24 tonnes of carbon dioxide.
According to US EPA a typical passenger vehicle emits approximately 4.6 tonnes of carbon dioxide gas every year. Each kilometer of shelterbelt trees has the potential to remove approximately the same mass of carbon dioxide from the atmosphere that 6 passenger cars emit every year while also earning up to 24 carbon credits.
