ICF is trusted by public- and private-sector clients worldwide to address the complex, interconnected causes and effects of climate variability and change.

We are internationally recognized for our leadership in carbon accounting, greenhouse gas mitigation, climate and extreme weather vulnerability assessment, and resilience planning.

Our experts literally wrote the book on how to account for carbon. Our team members have trained hundreds of experts in dozens of countries and in all 50 U.S. states to measure and manage carbon emissions. We’ve worked with scores of city, state, and commercial clients to inventory and take actions to reduce their emissions and build their resilience to climate impacts.

In the United States, ICF supported the first greenhouse gas inventory, the first mandatory greenhouse gas reporting program, the first federal agency climate adaptation program, and the first federal agency infrastructure resilience framework.  ICF is a leading provider of policy support to the European Union on climate change, and has supported the development of China’s emissions trading scheme.

Our clients understand that we are dedicated to finding solutions that support their organization’s mission into the future, backed by research and supported by objective analysis. We are strategic doers who provide practical advice and implementation, offering our clients complete solutions to their climate-related challenges.
