The Energy Modeling Program works to improve the quality and accessibility of quantitative modeling of energy systems, climate change mitigation, environmental contamination, and sustainable development. We build widely-used modeling tools, including LEAP and NEMO; conduct innovative modeling projects; and provide training and technical support to practitioners around the world.
Our mission emphasizes connecting modeling to sustainable development in low- and middle-income countries, and democratizing the use of models through transparency and capacity-building. We routinely create, apply and support models to inform national energy strategies, nationally determined contributions (NDCs) to the Paris Agreement, air pollution policies, power development plans, and long-term low emission development strategies (LT-LEDS). We engage in a range of interdisciplinary modeling work, including analyses of the water-energy-food nexus, energy-economy interactions, and health impacts of air and water pollution.
