If your farming practices fall within the required guidelines, you can apply for carbon credits (credits recognized by the Government of Canada for 1 tonne of CO2 equivalent reduced, removed, or sequestrated from the atmosphere and stored). Best farming practices include soil sequestration, manure management and fossil fuel reductions. A good starting point is the Alberta Governments, Agriculture and Forestry, webpage. From there, there are several links to other sites regarding specific queries.
As the trading of carbon credits is in its infancy, we recommend that any contract made with a private aggregator be short term. In time, regulations, verification systems, and fair market prices will prevail, ensuring that fair value is received for carbon credits.
