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

We are internationally recognized for our leadership in carbon accounting, greenhouse gas mitigation, climate and extreme weather vulnerability assessment, and adaptation planning. In the United States alone, 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.

Our experts literally wrote the book on how to account for carbon, and our team members have trained hundreds of experts in dozens of countries and in all 50 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.

We even developed a set of climate risk screening tools to help the World Bank protect its investments – the largest climate risk screening effort ever undertaken by any organization.

Our clients understand that we are dedicated to finding solutions to address the causes and impacts of climate change, backed by research and supported by objective analysis. We are strategic doers who provide practical advice and implementation, offering our clients a complete solution that works to integrate climate action into the organization’s mission.
