We purchase our carbon offsets from the Bonneville Environmental Foundation (BEF). BEF is a non-profit organization based in Portland, OR, whose mission is to support the development of renewable energy and watershed restoration while empowering people to shrink their carbon footprint. The price we charge to you is the same price as if you were to buy the offset directly from BEF. Currently, the pricing for carbon offsets is $26.65 per ton of carbon that is offset. Because we buy in bulk, we obtain discounts that allow us to cover our expenses and to grow Green Shipping.
