This Unit models national and regional energy systems using system dynamics, optimization, statistical methods and machine learning to simulate energy supply and demand, sectoral GHG emissions, and decarbonization pathways. It maps energy production by source (e.g. coal, natural gas, renewables, nuclear, bioenergy, etc.) and records sectoral energy use (transport, buildings, industry, agriculture, etc.), linking these to emissions, within physical modelling, and advanced AI applications for real-time monitoring of carbon fluxes.
Climate mitigation strategies such as consumption efficiency, transitions to cleaner fuels, electrification, carbon pricing, and credits are tested through scenario simulations to assess impacts on emissions and energy uses. Among the models used are LEAP, BALMOREL, En-ROADS and MaritimeGCH. Tailor-made models incorporate regional specifics, spatiotemporal and uncertainty aspects, supporting the development of climate-neutral, efficient, and technologically feasible energy transition pathways.
Under the auspices of the United Nations Secretary-General, the Council of Engineers for the Energy Transition (CEET) is a global, high-level body of engineers and energy systems experts to contribute to the UN Secretary-General’s goal to build a coalition to achieve net zero emissions by 2050, and to the UN generally on engineering pathways to achieve comprehensive decarbonization by mid-century. The work of the CEET is undertaken by an independent and impartial council of recognized global experts, serving in their personal capacity and responding to requests for information by the UN System.

Climate Interactive creates and shares tools that drive effective and equitable climate action.
Their work: Critically, the Paris Agreement asks all countries to prepare by 2020 low-emission development strategies that chart out how emissions will fall through to 2050. SDSN has played an instrumental role in developing and popularizing the concept of long-term pathways through the Deep Decarbonization Pathways Project (DDPP). The Paris Agreement also emphasizes the central role of advances in low-emission technologies and their diffusion. The annual Zero Emissions Solutions Conference (formerly the Low-Emissions Solutions Conference) spearheaded by SDSN, the World Business Council for Sustainable Development (WBCSD) and ICLEI – Local Governments for Sustainability was launched at COP22 in Morocco and aims to advance the pace of development for key technologies. As scientist and engineers have demonstrated, we have the technologies and means to decarbonize our economy, it’s up to nations, businesses, and cities to set on a course today for a carbon neutral tomorrow.
