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.
