Actually Microsoft has promised to go further, namely being carbon negative by 2030 and removing even historical carbon emissions by 2050: https://blogs.micros

  Nice, I had missed that! I'm actually super impressed with Walmart's commitment too: https://www.axios.com/walmart-climate-plan-zero-carbon-emissions-3ffb8fcc-cc39-41a7-a989-1d2ac48d8193.html https://www.axios.com/walmart-climate-plan-zero-carbon-emiss... They have huge amounts of refrigeration, and will act a a buyer that forces refrigeration supply chains to start using refrigerants with less global warming potential, which can often reach into 1000x or more of CO2. (CO2 can be used as a refrigerant, but requires instead conditions that pit a lot demand onto materials...). And Walmart is going to require these to be super cost effective. MS and Google have lots of slack in their budgets, so if DC energy costs go up by 30%, no big deal. Walmart will be forcing the tech to be cheap, meaning that everybody can adopt it once Walmart does. When Walmart it more ambitious than an entire political party in the US, our politics are completely messed up. Walmart should not have to pull along the word, we should be pushing Walmart. It's ridiculous.
