- Combined heat and power (CHP), which produces both heat and electricity at the same time, is so efficient that it can reduce energy use and emit less carbon dioxide (CO₂) than conventional fossil fuel use. This article attempts to look empirically into the impact of CHP share in total electricity generation on CO₂ emissions in a cross-country context. Data from 35 countries during the period 2009–2015 are used. For this purpose, the variable of CO₂ emissions is regressed on three variables of constant, gross domestic product, and CHP share using two robust estimators. The results show that the level of CHP share of a country affects the level of its CO₂ emissions negatively. That is, CHP leads to less CO₂ emissions.
