Have you contacted Hetzner? They claim 0% emission impact https://www.hetzner.com/unternehmen/umweltschutz/

Except their Hardware needs to be manifactured aswell and that's a significant part of the CO2 "cost" of a datacenter. Though Hetzner does do a lot to in that regard with their reuse of older hardware and very energy efficient data centers.

Where's it say that?

The linked web page has a logo with title "0% CO2 emissions | 100% green electricity"

We had a hard time finding this data when experimenting with carbon aware scheduling in Nomad. There seem to be a lot of orgs working on this, but it’s all third party as far as I know. I couldn’t find a first party (eg Amazon, Microsoft, Google, etc) that provided this data via an API. Very frustrating. There are a couple resources linked here: https://github.com/hashicorp/nomad/blob/h-carbon-meta/CARBON... The silv…

GCP has https://cloud.google.com/carbon-footprint

With AWS last I checked (which might have been 2 years ago) they advertised regions powered by renewable energy sources. You can see it better here: https://sustainability.aboutamazon.com/around-the-globe?ener... But as to calculate exactly the amount of carbon footprint for your VPS, I think you are out of luck, because exact numbers are either opaque or required you take AWS at their word.

They also announced this in March: https://aws.amazon.com/about-aws/whats-new/2022/03/aws-launc...

Because your server is not emitting CO2, whatever you make up, is just something you made up (best industry practices, conversely, are fictions you choose to believe). If you really care, put a watt meter on it and try to reduce its power consumption. Because you don't have control of the data center's grid connections. Good luck.

I agree with this.

You also don't know the exact mix of sources generating the particular amount of power consumed by your data centers instantaneously. Since each generation source has it's own (complicated) emissions profile, the amount generated by different sources is necessary to compute your CO(2) impact.

A power grid can calculate it's CO2 impact of generation more easily because they only need to use emissions measurements or emissions models for the total generation plant. Most places serious about air quality opt for sensors, but CO2 isn't their most pressing measurement. Typically NO2, NO3, CO, and unburned hydrocarbons are more regulated.

If you want to make an impact to GHG, setting aside quantifying the impact, switch to a renewables-backed power supply and increase your efficiency.
