NegaWatt Consulting has partnered with BEF to balance the environmental footprint we cannot avoid.

Through the purchase of Green-e Energy Certified Renewable Energy Certificates (RECs) purchased from BEF, we ensure that all our electricity use is offset by U.S.-based renewable resources.

Verified Carbon Offsets purchased from BEF balance the greenhouse gas emissions associated with our operations, including business travel.

Water Restoration Certificates purchased from BEF have restored water to critically dewatered rivers and streams equivalent to our day-to-day water use.
