Before revision: Theoretical underpinnings In order for an “emission free” power plant to have a net negative impact on greenhouse gas emissions of the energy supply it must do two things: produce enough emission-less electricity to offset the greenhouse gas emissions that it is responsible for continue to produce electricity to offset emissions from existing or potential fossil fuel plants directly responsible for (e.g.
