GREENER principles for environmentally sustainable computational science

The carbon footprint of scientific computing is substantial, but environmentally sustainable computational science (ESCS) a nascent field with many opportunities to thrive. To realize the immense green and continued, yet sustainable, growth computer science, we must take coordinated approach our current challenges, including greater awareness transparency, improved estimation wider reporting environmental impacts. Here, present snapshot where ESCS stands today introduce GREENER set principles, as well guidance for best practices moving forward. sciences there an opportunity lead way towards research. In this Perspective authors lay some fundamental principles transform into exemplar broad societal impact sustainability.
