We care about both. All the major cloud platforms are putting a lot of work into powering their data centers with as much renewable energy as possible, and surfacing carbon information to engineers using the platforms. See the feature Google just released, for example: https://cloud.google.com/carbon-footprint. It's even a somewhat mainstream topic - I'm pretty sure I've seen NYT articles about the carbon footprint of Zoom calls and Netflix streaming.

It's something I personally think about a lot, and I know many others do. Here's a community of people that discuss this topic a lot if you're interested: https://climateaction.tech/
