SRM & Brazil

As global temperatures approach 1.5°C of warming, Brazil is already experiencing the worsening impacts of climate change, including the degradation of the Amazon and reduced agricultural productivity. With risks mounting, there is growing interest in a set of ideas to cool the planet. What are these ideas, and what could they mean for Brazil?

SRM360 worked in collaboration with the Brazilian Ministry of Science, Technology and Innovation (MCTI) and the Climate and Society Institute (iCS) to co-create a primer explaining how SRM technologies could influence Brazil’s climate risks, including impacts on heat, water, agriculture, and the Amazon, while highlighting the potential benefits, uncertainties, and governance considerations.

The primer was developed to inform discussion at a national seminar hosted by MCTI and supported by iCS on 24 September 2025. The event brought together national and international experts – including researchers, policymakers, and civil society leaders – to share insights on SRM science, review potential regional and global effects, and discuss ethical, governance, and policy challenges, with the seminar streamed online and translated into English to ensure broad public access.

A recording of the seminar is available here.

This primer is also available in Portuguese.
