Marginal carbon intensity differs from average carbon intensity: average carbon intensity is total emissions divided by total generation, while marginal carbon intensity is the additional emissions triggered by one additional watt of load.

VerifiedMarginal carbon intensity reflects the additional emissions triggered by the generating units activated by incremental electricity consumption, and is more instructive for users who wish to reduce emissions by shifting loads.79% similarUnverifiedThe degree of carbon neutrality of synthetic fuels depends on the energy sources and carbon sources of the entire production system; only by using low-carbon electricity and carbon already in the cycle can the carbon loop be more thoroughly closed.75% similarUnverifiedElectricity Maps focuses on average carbon intensity, while WattTime emphasizes marginal carbon intensity.74% similarUnverified根据IPCC评估，核电全生命周期碳排放强度约为12克二氧化碳当量/千瓦时，远低于天然气发电（约490克）和煤电（约820克）74% similarUnverifiedThe carbon emission intensity of coal-fired power generation is approximately 800–1000 gCO₂/kWh, combined-cycle gas is approximately 350–450 gCO₂/kWh, and wind and solar are nearly zero during the operational phase.72% similar
