Fugitive Emissions
Unintended releases of greenhouse gases during extraction, processing, and distribution of fossil fuels. Methane leaks from natural gas systems are a major source of fugitive emissions.
Why It Matters
Methane is 80x more potent than CO2 over 20 years. Fugitive emissions mean natural gas is not as clean as its combustion chemistry suggests, strengthening the case for electrification.

Emissions Factor
The amount of CO₂ (or CO₂ equivalent) emitted per unit of electricity generated, typically in lbs CO₂/kWh or kg CO₂/MWh. It varies by region based on the generation mix.
Carbon Intensity
The amount of CO2 emissions per unit of electricity generated. Varies by grid mix (coal, gas, renewables).
