India has been contributing to the evaluation, discussion and implementation of solar-geoengineering research for almost a decade, in line with the call by A. Atiq Rahman and colleagues for developing countries to take the lead in this realm (see Nature 556, 22–24; 2018).

The Indian government’s Department of Science and Technology launched a major research initiative in 2017 at the Indian Institute of Science in Bangalore to understand the implications of solar geoengineering on developing countries. The first annual meeting of experts and policymakers to discuss how this research could be done in India was held in 2017.

The department has also funded a geoengineering climate-modelling research programme over the past five years. This has revealed, for example, how solar geoengineering could affect the global water cycle and extreme events and cyclones in the Bay of Bengal (see G. Bala and B. Nag Clim. Dyn. 39, 1527–1542; 2012; and A. Nalam et al. Clim. Dyn. 50, 3375–3395; 2018).

Furthermore, New Delhi’s Council on Energy, Environment and Water has held three international conferences since 2011 to identify India’s role in developing regional and global governance of solar-geoengineering research and technologies.
