Propose the idea to build new, or transform the existing quality testing to reduce the climate impact. Running computing tasks that consume a high level of resources and that have already been planned, not last minute, when the electricity is as clean as possible because it comes from renewable sources. I want to explain how this is actually possible based on the projects from two organizations: Electricity Maps and WattTime, they provide APIs that can be used to obtain real CO2 emissions forecasts in order to make carbon efficient decisions.
