It focuses on upstream ingredients and energy inputs, excluding brewing operations, packaging, and distribution, to create a modular toolkit (i.e., individual emission factors adaptable to brewery-specific inputs) for breweries in Northern Colorado aiming to reduce environmental impacts. Greenhouse gas emissions and eutrophication are analyzed. While not a full life cycle assessment, this study promotes more equitable access to sustainability metrics and provides a foundation for future carbon footprints, hotspot analyses, and brewery-level emissions inventories.born digitalStudent worksengCopyright and other restrictions may apply.
