Jack Wilson to Speak at ACLCA Conference

Jack Wilson will present “Operating on the Margins: Making Sense of Marginal Electricity Emission Factors” at the American Center for Life Cycle Assessment (ACLCA) Conference in San Diego, California. He will speak on September 16 at 11:00 a.m. PT.

Geosyntec’s Eric Amundsen coauthored the presentation.

Jack is an Engineer based in Colorado who focuses on carbon management and advisory services, including greenhouse gas emissions reporting and decarbonization strategy. He brings expertise in energy efficiency, renewable energy technologies and procurement, low-carbon fuels, energy storage, life cycle assessment (LCA), and sustainability.

ACLCA 2026 brings together LCA professionals, including experts from industry, consulting, government, and academia to share insights, advance best practices, and explore innovative approaches to sustainability and environmental decision-making.

Abstract: “Operating on the Margins: Making Sense of Marginal Electricity Emission Factors”

Electricity consumption from the grid often represents a significant share of life cycle inventories and broader environmental assessments, making the selection of electricity emission factors an important methodological choice. Attributional assessments typically rely on average electricity emission factors that reflect the average emissions intensity of the existing generation mix. In contrast, consequential assessments often apply marginal emission factors to estimate the emission changes associated with changes in electricity demand.

Multiple formulations of marginal emission factors exist, each reflecting different temporal and structural aspects of electricity grid response. This presentation provides a conceptual overview of three types of marginal emission factors: operating margin emission factors, which capture short-run dispatch responses of existing generation assets; build margin emission factors, which reflect longer-term capacity expansion decisions; and combined margin emission factors, which integrate both short-run and long-run system dynamics.
