CO2 production of starfrosch

kusBlog, News

I want to reduce my CO2 footprint. It’s pretty good so far and I reach my climate goals for 2019 according to several footprint calculators. This and the following calculations are not very scientific, but I’m happy with approximate calculations.

One thing I almost failed to calculate is the CO2 production of our server at our provider and sponsor DigitalOcean. So I asked on Twitter.

They don’t offer green energy, but I’m not the only one who demands it.

They asked me to open a ticket. I did. The answer was 100% (/&%รง*: “We don’t really have a way to do that at this time, I’m afraid.”

Energy has a huge impact on cost of running a datacenter, so I’m 100% sure they know how much they spend, but they don’t want or can’t to share it.

So I started to research. vCPU is the main factor for energy consumption of a droplet.

A vCPU consumes between 0.069 and 0.075 kWh. Thats 604.44 to 657 kW/year.

Coal energy produces 1001g CO2/kWh

Hydroelectric produces 4g CO2/kWh

Our DigitalOcean droplet has 2 vCPUs. That means CO2 production of our 2vCPU droplet per year with coal energy is max:

2 vCPU x 0.075 kWh * 1001 g * 24 hours * 365 days = 1’315’315g CO2/year

Our @digitalocean droplet produces approximatly 1.3 tons of CO2 per year. I compensated this with a 44$/year donation with @myclimate. I know this is not perfect, but I currently don’t know a better approach.

Now we only need to know how many vCPU DigitalOcean runs to approximaly calculate their CO2 emissions, but that’s not my problem, I’m fixing things that I can influence.

Update: Gray energy and external services are not included in this calculations, it’s just vCPUs energy consumption operated with coal energy.

Update2: I got a little bit better answer from DigitalOcean support.

Thanks for getting back to us.

“We apologize that this answer didn’t meet your needs. As Mike mentioned we don’t have the tools to calculate your CO2 foot print. The reason for this is that in many of our datacenters are collocated and as such aren’t able to calculate the energy costs. From your blog it looks like you were able to do a estimation based upon vCPU which can be a good estimation to go by.

We are aware of the need to have green energy and are always looking for ways we can improve that. “
