Loughlin, D. AND C. Nolte. Annual release of updated GLIMPSE/GCAM-USA tool. U.S. Environmental Protection Agency, Washington, DC, 2023.
Impact/Purpose:
GLIMPSE is a decision support tool being developed at the U.S. EPA to assist the EPA, states, and others with long-term environmental and energy planning. GLIMPSE is an acronym for the “GCAM Long-Term Interactive Multi-Pollutant Scenario Evaluator”, where GCAM is the “Global Change Analysis Model.” GCAM is a human-Earth systems model, developed by Pacific Northwest National Laboratory, which simulates the co-evolution of the economy, energy system, land use, and climate systems, including how this co-evolution is shaped by policy and other external factors. GLIMPSE acts as a graphical user interface for GCAM. Using GLIMPSE, decisionmakers and analysts at the national, regional, and state levels can examine potential policies, investigate the impacts of emerging technologies, develop cost-effective strategies for meeting air pollutant and greenhouse gas (GHG) mitigation targets, and explore the tradeoffs at the nexus of energy, water, and land use.
Description:
Annual updates will be made to GLIMPSE/GCAM-USA and shared with users and partners. Updates are expected to include integration of new versions of GCAM, addition of policy levers, and enhancements to usability.
