Our expertise spans key environmental sectors and emerging solutions. We work across disciplines and geographies to help clients navigate complex systems and drive meaningful environmental progress.

  • Ocean

    The ocean is the foundation of life on Earth, regulating our climate, sustaining biodiversity, and supporting the livelihoods of billions. Yet it faces escalating threats from climate change, habitat destruction, and unsustainable resource management. Protecting and restoring ocean ecosystems requires bold, science-driven strategies that balance conservation with the needs of coastal communities. We work with clients to advance sustainable fisheries and aquaculture, strengthen marine biodiversity protection, scale ocean-climate solutions, and promote a just and resilient blue economy.

  • Climate Change Mitigation

    The transition to a low-carbon future is underway, but the pace must accelerate to meet global climate goals. We work with philanthropists, policymakers, industry leaders, and nonprofits to advance high-impact solutions—from modernizing electricity grids to scaling clean transportation and tackling super-pollutants. Our expertise spans grid modernization, methane and short-lived climate pollutant reduction, cooling efficiency, transportation decarbonization, building electrification, and offshore wind, helping to cut emissions and support a just transition to a net-zero economy.

  • Climate Adaptation and Resilience

    Even with current mitigation efforts, the world is on track to exceed the critical 2°C threshold and is already experiencing severe climate impacts. These impacts, which fall hardest on the most vulnerable, underscore the urgent need to prioritize adaptation. CEA increasingly integrates resilience into our work with philanthropic and NGO clients, focusing on nature-based solutions, built environment adaptation, watershed management, finance and insurance mechanisms, disaster preparedness, climate justice, and gender intersections to strengthen climate resilience globally.

  • Sustainable Agriculture, Land Use, and Forestry

    Sustainable agriculture and healthy forests and grasslands are essential for climate stability, biodiversity, human well-being, and food and water security. Our food systems must become more resilient, lower emissions, and stay within planetary boundaries while feeding a growing population. We work with clients to cut agricultural methane and nitrous oxide emissions, protect forests and soil carbon, uphold the land rights and food sovereignty of Indigenous Peoples and local communities, and promote climate- and water-smart agricultural practices.

  • Freshwater Systems

    Water scarcity, pollution, and ecosystem degradation are intensifying under climate change and increasing demand. Clean, reliable freshwater is essential for human and ecological health, yet billions still lack access. We work with clients to protect and restore freshwater ecosystems, advance sustainable water management, address pollution, and expand safe water access. Our services include designing national and global water strategies, conducting funding analyses, and managing grantmaking programs that build more resilient and equitable freshwater systems.

  • Conservation

    The health of the planet and human well-being depend on thriving biodiversity, yet ecosystems and species are declining rapidly due to habitat loss, climate change, and unsustainable resource use. Reversing this trend requires bold, inclusive conservation strategies. CEA supports conservation strategies for individual species, ecosystems, and landscapes through work on protected areas, conservation finance, supply-chain commitments, and community-based solutions. We also bring expertise in key policy mechanisms—such as the Global Biodiversity Framework—and other effective area-based conservation measures.

  • Equity and Human Dimensions

    The burdens of climate change and biodiversity loss fall most heavily on those least responsible, deepening existing inequalities and threatening livelihoods, cultures, and ways of life. Advancing a just and climate-stable future requires centering the voices, leadership, and rights of frontline communities. We work with clients to embed justice, equity, diversity, and inclusion principles across conservation and climate strategies—ensuring that solutions are not only effective but also equitable, inclusive, and rooted in the priorities of those most impacted.
