• Portfolios / Cross-Cutting Strategies

    Promoting the fundamental social and economic conditions necessary for change requires strategies that work effectively across sectors.

  • Portfolios / Cross-Cutting Strategies

    Building a safe climate and prosperous future depends on shifting investment away from fossil fuels and mobilizing financing for clean energy and infrastructure.

    When constituencies and policymakers are well-informed about climate science, impacts, and solutions, it creates public pressure and political space for ambitious climate policy.

The Cross-Cutting Strategies Portfolio

To support the social and economic conditions necessary for climate action, ClimateWorks collaborates on multiple strategies that cut across economic and emission sectors to accelerate the global low-carbon transition.

Communications & Public Engagement

Climate action is more likely to succeed when policymakers and constituencies are well informed about both the damaging effects and costs of climate change and the possible solutions. Grantees in the Cross-Cutting Strategies portfolio are making this possible by helping shape the political and media narrative, increasing public awareness, and helping create political space for ambitious new policies. The portfolio’s main priorities are to promote clear and accurate communication of climate science, and to shift the public’s focus on climate change impacts, drivers, and solutions.

Climate Policy

Significant reductions in greenhouse gas emissions can be achieved through strong, climate-focused policies, such as carbon pricing, state- and national-level emissions reductions targets, and multilateral climate agreements. Efforts such as these are already helping to shift major economies away from carbon-intensive practices — but the scale and scope of global climate policy needs to expand quickly. Through cross-cutting strategies in the policy arena, ClimateWorks and its partners proactively encourage the adoption and implementation of ambitious climate policies in high-priority regions.

Sustainable Finance

The world is more likely to avoid the damaging effects of climate change if we decrease investment in fossil fuels that are responsible for greenhouse gas emissions and increase investment in sustainable, clean energy sources and infrastructure. Through the Cross-Cutting Strategies portfolio, ClimateWorks and its partners target creating an ecosystem of accessible capital, investable projects and companies, clear standards, transparent information, and supportive policy with accurate price signals — all vital to a sustainable finance environment.


Cross-Cutting Strategies Program Team
