Decarbonisation
The process of reducing greenhouse gas emissions from operations toward zero — through energy efficiency, fuel switching, electrification, and renewable energy adoption.
Decarbonisation refers to the systematic reduction of greenhouse gas emissions from business operations — through a combination of energy efficiency improvements, fuel switching from fossil fuels to lower-carbon alternatives, electrification of thermal processes, and procurement of renewable electricity. The goal is to reduce absolute emissions toward zero, not simply improve emission intensity.
Decarbonisation vs net zero
Decarbonisation is the operational reduction of emissions. Net zero is the target state where remaining emissions are balanced by removals (carbon capture, reforestation). Reaching net zero without genuine decarbonisation — by relying entirely on offsets — is not credible under science-based target frameworks.
Priority decarbonisation levers for manufacturers
- Energy efficiency — reduce energy consumption per unit output
- Fuel switching — replace coal and furnace oil with natural gas or biomass
- Electrification — convert thermal processes to electric where feasible
- Renewable electricity — switch Scope 2 to zero-emission sources via PPAs or rooftop solar
Measuring baseline Scope 1 and Scope 2 accurately is the prerequisite for any decarbonisation programme — you cannot track reduction without a reliable starting point.
