Emissions of carbon dioxide resulting from human activity are a major cause of global warming. A significant portion of these emissions come from energy consumption for transportation, home heating and home electricity production. Forests absorb and store carbon dioxide efficiently and provide an opportunity for homeowners and businesses to voluntarily offset the environmental damage caused by energy consumption. Through photosynthesis, trees take CO₂ out of the air, replacing it with life-giving oxygen.

ProjectGreenGift.com carbon dioxide offsets are being achieved through a tree-planting program undertaken by the Confederated Salish and Kootenai (CSK) Tribes in the State of Montana. The CSK Tribes are comprised of the Bitterroot Salish, the Pend d'Oreille and the Kootenai tribes. They currently reside in the Flathead Reservation which is made up of 1.3 million acres in northwest Montana but their ancestors lived in the territory now known as western Montana, parts of Idaho, British Columbia and Wyoming.

Each recipient will receive an Environmental Remediation Certificate from Sustainable Forestry Management Ltd. (SFM) certifying that trees planted will offset your CO₂ emissions for one year.

In 2001, SFM purchased the carbon rights to an area within the CSK Tribal lands that had been destroyed by fire. The CSK Tribe has used the proceeds for the reforestation of the area (seedlings and cost of planting). Furthermore, contractual arrangements call for the CSK Tribes to maintain the carbon stock in the land and deliver a report attesting to the carbon sequestration and projections thereof every five years.
