The group has now applauded Bezos for his philanthropic fund but maintains its criticism of Amazon's support of traditional energy producers.
"As history has taught us, true visionaries stand up against entrenched systems, often at great cost to themselves. We applaud Jeff Bezos' philanthropy, but one hand cannot give what the other is taking away," the group said via its Twitter account.
"The people of Earth need to know: When is Amazon going to stop helping oil and gas companies ravage Earth with still more oil and gas wells? When is Amazon going to stop funding climate-denying think tanks like the Competitive Enterprise Institute and climate-delaying policy? When will Amazon take responsibility for the lungs of children near its warehouses by moving from diesel to all-electric trucking?"
The group in April last year gained over 8,700 signatures from Amazon employees for a petition demanding that Bezos and Amazon's board implement a better climate plan. Amazon's policy on the issue of supplying computing infrastructure to the energy industry is that it "should have access to the same technologies as other industries".
