Greenhouse Gas Emission Inventory

The Alaska Department of Environmental Conservation, Division of Air Quality, periodically updates the sources and amounts of "greenhouse gas" (GHG) emissions for Alaska as time and resources allow. The information and methodologies used in preparing the updates are described in the various reports. The inventory is not intended to be a policy statement but to simply help inform discussions about GHG emissions. 

We thank you for your interest and any suggestions you have.

Alaska Community Criteria Pollutant and Greenhouse Gas Emission Inventory Tool Development

  • Summary: This project aimed to improve the accuracy of previously generated community-level emissions estimates by combining modeled inventory data with directly surveyed local activity data. This report documents the objectives, methods, quality assurance measures, and data management practices used to develop a robust emissions inventory under the State of Alaska’s IRACAA103 grant. The project targeted multiple sectors (residential, commercial, industrial, power generation, transportation, etc.) and fuel types (wood, oil, diesel, gasoline, etc.), with the goal of informing air quality planning and regulatory compliance efforts through more accurate, community-specific data. Tailored survey questionnaires were developed to capture local data on fuel consumption, heating devices, commercial operations, industrial activity, and other relevant practices, aligning with the categories used in the existing emissions models. By ensuring that the survey covered the same sectors and fuel types as the modeled inventory, the project enabled one-to-one comparisons between modeled estimates and actual reported activities across different source categories.

EPA's Climate Pollution Reduction Grants

  • Summary: Alaska received a CPRG planning grant in 2023, to make Alaskan entities eligible to compete for CPRG Implementation Grants. EPA intended for these grants to be used to design climate action plans that incorporate a variety of measures to reduce GHG emissions from across their economies in six key sectors (electricity generation, industry, transportation, buildings, agriculture/natural and working lands, and waste management). These plans contain a list of quantified GHG reduction measures that could be implemented by state agencies, municipalities, tribal consortia, and councils of government. Measures for this plan were required to be “near-term, high-priority, implementation ready measures.”  In pursuit of this goal, Alaska’s measures are focused on energy sustainability and energy sovereignty, based on community input and guidance. Nationwide, planning grantees received their awards in the of fall 2023 and must generate three deliverables: a Priority Climate Action Plan, a Comprehensive Climate Action Plan, and a final Report. Alaska has submitted the following deliverables:
