Abstract

We present version 2.0 of AD-MERGE, an integrated assessment model that incorporates reactive and proactive adaptation strategies as well as mitigation options. AD-MERGE-2.0 builds on its predecessor by incorporating improved geographic disaggregation, enhanced technology representation, and updated assessments of climate damages and adaptation. In particular, this new version introduces six additional regions and includes new energy technologies, with a focus on variable renewable energy mechanisms.
We examine three main scenarios with AD-MERGE 2.0: Baseline, Reference and Announced Pledges. The first is our calibration scenario (based on SSP2-7.0) and provides a counterfactual baseline for comparison purposes, as it excludes climate damages from decision making. The second scenario represents the evolution of world energy systems under existing policies and measures and is based on the IEA's Stated Policy Scenario (STEPS). The third scenario corresponds to net-zero GHG emissions by 2100, based on the IEA's Announced Pledges Scenario (APS).
The improved regional disaggregation and energy technology representation in AD-MERGE-2.0 allows for a more detailed and accurate assessment of climate policy impacts, particularly in the context of a global transition to low-carbon energy systems.
