Environmental Sustainability, Climate Charter, August 2025

As climate and environmental crises intensify, the humanitarian sector must take urgent action to reduce its environmental footprint while continuing to deliver timely, effective, and principled assistance. Commitment 2 of the Climate and Environment Charter calls on organizations to minimize the environmental and climate impact of humanitarian activities, and this guidance page supports that commitment with practical tools and resources. Further, these resources aim to support the implementation of the “Common Donor Priority Actions for Greening Humanitarian Assistance.” Find the recording and presentations of the online launch event held with the Donor Greening Group.

The Climater Charter developed a curated collection of resources to help humanitarian organizations strengthen environmental sustainability across their operations and programs. From environmental screening tools and carbon calculators to guidance on sustainable procurement, clean energy transitions, and waste reduction, this guidance is designed to help organizations avoid, minimize, and manage environmental harm.
