Environmental issues such as climate change, air and water pollution, and non-renewable energy, to name a few, continue to threaten a sustainable future. This Focus highlights the potential for computational tools to help address those challenges, as well as includes experts’ opinions on how these tools themselves can be improved to ensure a greener and more sustainable future.
This month’s Focus issue highlights ongoing work by computational scientists to help address the Sustainable Development Goals, as well as discusses how the sustainability of computational science itself can be improved.
Proponents often tout quantum computing as a more energy efficient alternative to classical computing methods. However, the extent to which it can reduce energy usage remains unclear, as experts have not yet agreed on metrics to determine its energy consumption.

Dr Carla Gomes, Ronald C. and Antonia V. Nielsen Professor of Computing and Information Science, director of the Institute for Computational Sustainability, and co-director of the newly established AI for Science Institute at Cornell University, discusses with Nature Computational Science her research on sustainability and how we can address the world’s most pressing issues little by little.
