2020-12-012018 Community greenhouse gas emissions inventory
★ 34Seattle's 2018 Community Greenhouse Gas Emissions Inventory, prepared by the Seattle Office of Sustainability & Environment, tracks and analyzes the city's greenhouse gas emissions across sectors including transportation, buildings, industry, and waste. The report compares 2018 emissions data against previous years, examines per capita trends, and outlines Seattle's climate reduction goals and strategies. Note: This document focuses on citywide carbon emissions and climate policy, and does not address Sea-Tac Airport noise issues. -
2017-12-01King County Greenhouse Gas Emissions Inventory: A 2015 Update
★ 32This December 2017 report inventories greenhouse gas emissions across King County, Washington, providing a comprehensive 2015 update that examines emissions by sector using geographic-based and consumption-based methodologies. It was prepared by Cascadia Consulting Group and Hammerschlag & Co. LLC, covering sources such as transportation, buildings, waste, and energy use. The report tracks changes in emissions over time and analyzes key data sources to help inform county-level climate and environmental policy decisions. -
Trump and Lee Zeldin EPA Greenhouse Gas Deregulation Announcement

The setting appears to be the Roosevelt Room or a similar formal White House venue, with an American flag and painted portrait visible in the background. -
2025-04-09U.S. Withdraws from Critical IMO Climate Meeting, Threatens Retaliation Over Emissions Pricing
Mike Schuler In a dramatic development at the International Maritime Organization’s (IMO) Marine Environment Protection Committee meeting in London, the Trump administration has announced the United States’ withdrawal from crucial maritime decarbonization negotiations taking place this week. The US government delivered a strongly worded message to IMO delegations, explicitly rejecting any measures that would impose -
2024-03-01Air Quality and Greenhouse Gas Technical Report: Sustainable Airport Master Plan Near-Term Projects
This technical report, prepared by Landrum & Brown for the Port of Seattle in March 2024, analyzes air quality and greenhouse gas emissions associated with near-term projects in the Sustainable Airport Master Plan for Sea-Tac Airport. It covers emission sources including aircraft, ground support equipment, stationary and mobile sources, and construction activities. Note that following changes to federal executive orders and a 2025 Supreme Court ruling, references to climate change preparedness and cumulative impact analysis were removed from the final version, leaving only the quantified GHG emissions disclosures. -
2024-03-01Appendix C: Air Quality and Greenhouse Gas Technical Report: Sustainable Airport Master Plan Near-Term Projects
Appendix C of the Sea-Tac Sustainable Airport Master Plan covers air quality and greenhouse gas emissions analyses prepared for the Port of Seattle by Landrum & Brown. It includes technical reports on emissions from aircraft, ground support equipment, construction, and other airport sources, as well as a human health risk assessment focused on ultrafine particles. Note that some climate-related sections originally included in the Draft Environmental Assessment were later removed following changes to federal executive orders and a 2025 Supreme Court ruling. -

WA’s largest oil refinery ramps up cleaner fuels as climate laws take hold
By Isabella Breda Seattle Times staff reporter CHERRY POINT, Whatcom County — Thick steam billowed from a series of towers and pipes, intricately woven together to form a powerhouse of the region’s energy production and Washington’s largest oil refinery. BP’s Cherry Point facility, which belched more than 2 million metric tons of climate-warming gases into -
2022-09-01King County Communitywide Consumption-Based GHG Emissions Inventory: Puget Sound Regional Emissions Analysis
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. -
2022-08-21Annexes to the inventory of U.S. GHG emissions and sinks
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.
