AWS isn't alone in having work to do to become more environmentally-friendly. Competitor Google received higher grades from Greenpeace the report gives Google a grade of B, while AWS got a D. Google has also committed to using 100% renewable energy too, although with no specific timeline. Google says about 35% of its operations are currently powered from green sources.
Microsoft, meanwhile stands somewhere in the middle between AWS and Google, receiving a C grade from Greenpeace. The company has committed to being 100% carbon-neutral.
"We know that 100% renewable energy is an ambitious goal that won't be possible overnight," the group of Amazon customers wrote. "While you pursue this journey, we would suggest some steps that will give us full confidence in AWS' commitment to renewable energy." Now there is more pressure than ever for the cloud to be green.
