Climate Justice
The 1.5°Climate Strategies Group acknowledges the disproportionate, negative impacts of fossil fuel extraction and dependence on marginalized communities in the United States and globally. These communities face systemic barriers to accessing crucial resources for a smooth transition to clean energy. As a donor collaborative, we are deeply committed to addressing climate injustices, recognizing institutional racism’s role in sustaining and exacerbating disparities. The 1.5°Climate Strategies Group emphasizes the urgent need to allocate additional financial resources and build capacity for the clean energy transition in disadvantaged communities, striving for a more equitable and sustainable future for all.
