A 2022 report by InfluenceMap examines how aviation industry interests shape climate policy at the UN's International Civil Aviation Organization (ICAO), finding that 31% of delegates at recent climate negotiations represented industry. The report highlights that ICAO's limited transparency practices—including non-disclosure agreements, restricted media access, and undisclosed delegate affiliations—allow corporate influence to steer global aviation emissions policy. As a result, ICAO has prioritized carbon offsetting over direct emissions reductions, with global aviation CO2 emissions projected to grow by 190–277% between 2015 and 2050.

Aviation's climate impact is roughly three times greater than its CO2 emissions alone, because burning jet fuel at altitude also produces contrails, induced cloudiness, and NOx byproducts that add significant additional warming. A 2020 study by 21 leading scientists found that in 2018, aviation accounted for approximately 5.9% of all human-caused global heating when these non-CO2 effects are included. The fact sheet calls for immediate action including contrail-avoidance flight routing, cleaner fuels, stricter emissions regulations, and reduced air traffic overall.

This 2022 report by EcoDataLab and Stockholm Environment Institute provides a consumption-based greenhouse gas emissions inventory for King County and the broader Puget Sound region, tracking emissions tied to residents' purchases and behaviors across categories such as transportation, food, housing, goods, and services. It analyzes historical emissions trends, neighborhood-level variations, and supply chain stages, then outlines potential strategies for reducing those emissions through policy changes and shifts in household consumption patterns.

This document is a technical annex to the U.S. Greenhouse Gas Emissions and Sinks Inventory, outlining the methodologies used to measure and categorize national greenhouse gas emissions from 1990 to 2015. It identifies 'key categories' — the emission sources with the greatest impact on total national greenhouse gas levels, trends, and uncertainty — using standardized IPCC guidelines. The largest emission sources identified include road transportation, coal-fired electricity generation, and natural gas combustion across industrial, residential, and commercial sectors.

This August 2022 report by Cascadia Consulting Group analyzes greenhouse gas emissions across King County, Washington, examining where emissions come from, what is driving trends over time, and how the county can meet its climate goals. The report covers sectors including transportation, electricity, natural gas, solid waste, and land use, tracking data from multiple inventory years and comparing per-capita emissions across jurisdictions. It also models future emissions scenarios to assess the impact of federal, state, and regional policies on reaching reduction targets through 2050.

This July 2022 report from the Mission Possible Partnership outlines a global strategy for reducing aviation's greenhouse gas emissions to net zero by 2050, in line with the 1.5°C climate target. It identifies key milestones, technologies, and investments needed across the aviation value chain, including sustainable aviation fuels and new propulsion systems. The strategy is intended to guide airlines, policymakers, and financial institutions in taking coordinated action this decade.

King County's 2020 Strategic Climate Action Plan (SCAP) is a five-year blueprint outlining the county's priorities for reducing greenhouse gas emissions and preparing for climate change impacts, with a strong emphasis on racial equity and frontline communities. The plan builds on accomplishments since the 2015 SCAP, including an 11 percent reduction in per-person emissions, expanded transit ridership, and increased green building certifications. It is updated every five years and guides collaboration across county departments, cities, community partners, and residents.
