Initial release of the COMMIT data set.
This scenario explorer presents a set of scenarios developed in the COMMIT project. COMMIT stands for Climate pOlicy assessment and Mitigation Modeling to Integrate national and global Transition pathways. The COMMIT project’s main aim has been to improve modelling of national low-carbon emission pathways and analysis of country contributions to the global ambition of the Paris Agreement. The main motivation for this aim was that a common understanding and coherent message from the research community in different parts of the world is crucial to support the international negotiation process on climate policy. COMMIT consisted of a consortium of a large number of national teams, who regularly support domestic climate policy-making in their respective countries (Australia, Brazil, Canada, China, EU, India, Indonesia, Japan, Russia, South Korea, USA) and leading global integrated assessment modelling teams (PBL, PIK, IIASA, RFFCMCC EIEE). The consortium was led by Detlef van Vuuren and Heleen van Soest (PBL Netherlands Environmental Assessment Agency).

The set of scenarios presented here revolves around the Bridge scenario, which was developed to study how the emissions gap between Nationally Determined Contributions (NDCs) and the global emissions levels needed to achieve the Paris Agreement's climate goals can be closed based on good practice policies (GPP). Next to these GPP and Bridge scenarios, the set contains different reference scenarios (a no new policies baseline, a current policies scenario, and an NDC scenario), as well as different scenarios limiting global warming to 2 degrees Celsius. The Bridge scenario builds upon the current policies scenario and assumes that specific good practice policies, which have shown to be effective in some countries, will be implemented globally from 2020 until 2030. After 2030, the bridge scenario transitions to a 2 °C scenario following a cost-effective pathway. A distinction is made between low/medium and high-income countries in terms of timing and stringency of good practice policy targets. The set of policies was defined in dialogue with national model teams, granting a more realistic scenario narrative.

Another set of scenarios included here consists of the Reference (here: Baseline) and Low-carbon scenarios as presented by Fragkos et al. in Energy.

The data is also available for download and interactive viewing at the COMMIT Scenario Explorer hosted by IIASA. The advantage of getting the data through the scenario explorer is that by registering with your email you will receive updates anytime there is a new version of this data set.
