Climate policy assessment and Mitigation Modelling to Integrate national and global Transition pathways (COMMIT)

The Paris Agreement's central aim is to strengthen the global response to the threat of climate change by keeping global temperature increase well below 2 degrees Celsius above pre-industrial levels and to pursue efforts to limit it even further to 1.5 degrees Celsius. In order to develop these strategies, scientific input on emission reduction potentials is needed not only at the country level but also at the global level to put national emissions pathways into the context of the global climate goal. A key contribution is model-based scenarios for low-carbon economies developed using national and global integrated assessment models, macro-economic models, and energy-economic systems models. This project aims to contribute to both (1) supporting the analytical capacity for national teams to provide analyses of long-term mitigation pathways and (2) creating a robust scientific understanding of the possibilities of different countries to mitigate greenhouse gas emissions in the context of the mid-century strategies and the overall objectives of the Paris Agreement. The project has two major objectives (1) to improve modelling of national low-carbon emission pathways; and (2) to improve analysis of contributions to the global ambition of the Paris Agreement.
