This report explores Big Tech’s actions that feed the climate crisis. Big Tech’s actions include: allowing disinformation to flourish online; providing cloud services to help oil and gas companies pump more fossil fuels; participating in trade organizations that lobby against policies that would help the US shrink emissions; producing ever-growing emissions of their own; and funding and promoting false solutions. This report ends with demands for Big Tech to stop these actions that fund the worsening of the climate crisis. To fight the climate crisis, Google, Meta, Microsoft, Apple, and Amazon need to: support policies that help the U.S. end its reliance on fossil fuels; withdraw from trade groups that lobby against climate mitigation; support climate mitigation efforts that have grassroots support, like shrinking fossil fuel and other polluting industries to cut greenhouse gas emissions at their source; stop providing cloud services to oil and gas companies; eliminate climate disinformation on your platforms; and create and follow measurable plans to get to carbon-zero, not ones based on speculative tech and wishful thinking.
