The Industrial Transformation Technology and  Investment Model (ITTIM) is a free and open-source tool that maps out transition pathways for regions to achieve non-emitting industrial sectors. It estimates a wide variety of associated outputs, such as industrial energy use, carbon dioxide emissions, energy expenditures, capital investment needs, and more.

The ITTIM currently includes datasets for China, Indonesia, Viet Nam, the Philippines, the United States, and each of the 48 contiguous U.S. states. It divides technologies into six tiers according to their cost and level of technological maturity. It also includes outputs for 15 different subindustries, including iron and steel, chemicals, non-metallic minerals, and non-ferrous metals. The tool is highly customizable, allowing users to explore varying decarbonization timeframes and to include or exclude specific subindustries or technologies.
