Instead of trying to make the station sites themselves greener, EVgo purchases renewable energy certificates, which it claims are “different than buying offsets of carbon because we can actually match the kWh used with the kWh we purchase, which provides financing for renewable energy projects such as wind and solar.” Like carbon offset markets, these projects require third party verification by self-certifying firms. Still, Das insisted “By purchasing RECs, we have a much bigger impact than installing distributed energy on site in each parking lot.”
