Carbon Free Cities & States

In the US, cities and states are at the forefront of climate change risk and opportunity. And while many are making climate commitments, they need strategic, cost-effective solutions and the technical assistance to bring those intentions to reality. Internationally, regions and countries are looking for a credible, economically viable path to full climate-neutrality.
RMI is working on all levels – domestically, internationally, and with subnational actors – to tackle climate change and deliver economic, health, and resiliency opportunities to all global citizens.

The RMI Difference

For more than 35 years, RMI has focused on practical climate change solutions that can stimulate growth, rather than be at odds with it. Because we work across multiple energy sectors we can deliver a holistic suite of services to cities, including cross-cutting research and analysis, facilitation of diverse stakeholders, and access to industry experts throughout our vast network. Our strategy is to work with cohorts of cities and focus on a limited number of near-term, high impact activities that can be launched quickly with concrete results.
