The IPCC-aligned 8-sector taxonomy used across PlainEmissions. Sector shares vary by country; the global averages below give the rough structural shape of the planetary emissions pie.
-
Energy
Global share: ~45%
Power generation, fossil-fuel extraction, refining — the largest single sector globally.
-
Transport
Global share: ~15%
Road, rail, aviation, shipping — fuel combustion in mobility, the most policy-active sector.
-
Buildings
Global share: ~10%
Residential and commercial heating, cooling, and appliance use — significant share.
-
Industry
Global share: ~14%
Manufacturing, cement, steel, chemicals — both energy and process emissions; hard to abate.
-
Agriculture
Global share: ~11%
Livestock, rice, fertilizer — methane and N2O dominate; long abatement timelines.
-
Land use & forestry (LULUCF)
Global share: variable
Forest growth/loss, soil carbon — net source or sink depending on country; most-disputed sector.
-
Waste
Global share: ~3%
Landfill methane, wastewater treatment — small but actionable via methane capture.
-
Fugitive emissions
Global share: ~3%
Methane leaks from oil & gas, coal mining — likely under-reported; satellite verification growing.
