BEF Solar Energy Offsets from the Bonneville Environmental Foundation (BEF) are a greenhouse gas offset product based upon renewable energy resources. For every unit of electricity generated from approved renewable sources, a specified amount of BEF Solar Energy Offsets is produced. A purchase of BEF Solar Energy Offsets supports new¹ renewable electricity generation, which displaces the burning of coal, gas, and other fossil fuels across the US.

Each BEF Solar Energy Offsets represents a reduction of a minimum of 1,295 pounds of CO2-equivalent (2,204.6 pounds = 1 metric ton). The product will be generated between 2009 and 2011 and will be made up of the following new renewable resources:

BEF uses the greenhouse gas offset methodology established in the Green-e® Climate Protocol for Renewable Energy for Solar Energy Offsets.

This is representative of the content of BEF carbon offsets at the time this label was created. BEF is both developing and purchasing new resources to add to its mix. As the product mix changes, BEF will disclose the changes on our web site. You may also call 503-248-1905 for information on our product mix.

Green-e® Climate is an independent certification program for greenhouse gas emission reductions (offsets) sold in the voluntary market.

That depends on whether you choose to keep the rights to the emissions reductions, or have BEF retire them for you. If you keep them, BEF will send you a confirmation that the emissions reductions now belong to you, for use in offsetting your own emissions (they are not, however, resellable since you have used them up by claiming them against your own emissions).

If you choose to make a contribution to BEF, and direct us to use it to retire a designated amount of BEF Offsets, we will do so. Your contribution has the same environmental effect as a purchase.

When comparing green power products, it is essential to check and ensure that the product you are buying contains all of its emissions reductions (e.g., that the CO2 emissions reductions haven't been sold already to someone else). If it does not, you may be paying a premium for an environmental benefit that has been double-sold, to you and someone else.
