Rethinking research funding through a sustainability Lens.

Research funders can play a transformative role in reducing the environmental footprint of science without compromising its quality or productivity. Scientific research is among the most energy- and resource-intensive sectors globally, with its carbon footprint estimated to rival that of the aviation industry-contributing approximately 2 % of global greenhouse gas emissions. Yet the organizations that fund scientific research, particularly in the United States, structurally disincentivize sustainability, often rewarding waste rather than resource efficiency. We highlight how this is beginning to change across Europe, where major funding agencies are leading a growing movement to embed sustainability into research operations-from including environmental impact assessments in grant proposals to supporting green lab certification programs. These policies are on track to accelerate operational efficiency, reduce costs, and align research practices with climate action goals. Finally, we outline specific policy reforms and practical steps that researchers, institutions, and funders everywhere can adopt to build a more sustainable future for science-one where environmental stewardship is a core expectation of research.
