Limiting global temperature increase to two degrees Celsius above pre-industrial levels, a target agreed to by more than 100 countries, requires dramatic cuts in carbon dioxide and other greenhouse gas emissions. Such a transformation necessitates a fundamental restructuring of the way energy and land are managed, driven by unparalleled policy commitment and coordination from all of the world’s major economies.
The LIMITS project assesses a series of questions that are critical for developing climate policies that can achieve the stringent two-degree goal. The focus of the project is on technological challenges, economics, required policy regimes, implementation obstacles, and local and national air quality and energy security impacts.
Researchers from IIASA’s Energy Program are using the MESSAGE-MACRO integrated assessment model to analyze the benefits of climate mitigation and the implications for strategies intended to achieve the two-degree goal. Program scientists will also examine historical trends in the diffusion of technology in order to inform future technological feasibility. IIASA’s Ecosystems Services and Management Program will use the GLOBIOM model to assess the environmental and economic implications of land use changes under the two-degree scenarios.
