methods for reducing greenhouse gas emissions, and removing
greenhouse gases from the atmosphere.

SEVENTH ASSESSMENT CYCLE

Context for the AR7 WGIII Report• “Policies and laws addressing mitigation have consistently expanded
since AR5.” {SYR SPM A.4}
• “Several mitigation options, notably solar energy, wind energy,
electrification of urban systems, urban green infrastructure, energy
efficiency, demand-side management, improved forest and crop/grassland
management, and reduced food waste and loss, are technically viable, arebecoming increasingly cost effective and are generally supported by thepublic.” {SYR SPM A.4.2}

SEVENTH ASSESSMENT CYCLE

Context for the AR7 WGIII Report• “Global GHG emissions in 2030 implied by nationally determined
contributions (NDCs) announced by October 2021 make it likely thatwarming will exceed 1.5°C during the 21st century and make it harder tolimit warming below 2°C. There are gaps between projected emissions
from implemented policies and those from NDCs and finance flows fallshort of the levels needed to meet climate goals across all sectors andregions.” {SYR SPM A.4}
• “Continued greenhouse gas emissions will lead to increasing globalwarming, with the best estimate of reaching 1.5°C in the near term inconsidered scenarios and modelled pathways.” {SYR SPM B.1}

SEVENTH ASSESSMENT CYCLE

Context for the AR7 WGIII Report• Limiting human-caused global warming requires net zero CO2 emissions.
Cumulative carbon emissions until the time of reaching net zero CO2emissions and the level of greenhouse gas emission reductions thisdecade largely determine whether warming can be limited to 1.5°C or 2°C(high confidence).
• Projected CO2 emissions from existing fossil fuel infrastructure without
additional abatement would exceed the remaining carbon budget for 1.5°C(50%) (high confidence). {2.3, 3.1, 3.3, Table 3.1} {SYR SPM B.5}

SEVENTH ASSESSMENT CYCLE

Context for the AR7 WGIII Report• All global modelled pathways that limit warming to 1.5°C (>50%) with noor limited overshoot, and those that limit warming to 2°C (>67%), involve
rapid and deep and, in most cases, immediate greenhouse gas emissions
reductions in all sectors this decade. Global net zero CO2 emissions arereached for these pathway categories, in the early 2050s and around theearly 2070s, respectively. (high confidence) {3.3, 3.4, 4.1, 4.5, Table 3.1}
(Figure SPM.5, Box SPM.1) {SYR SPM B.6}

SEVENTH ASSESSMENT CYCLE

Vision from WGIII• More cross Working Group integration, including integration with the Task
Force on National Greenhouse Gas Inventories• More integration within WGIII• Increased inclusivity
