Opening up the Guardian last week, I was presented with the lead story on the IPCC report on Climate Change. The full report is not for the faint hearted at 1,300+ pages, but they do have a lightweight summary (more my style😉), which at 39 pages, is a bit more palatable. What struck me was the clarity of the data and the message it sends i.e. we all need to get off our rear ends to contribute to fixing this. It’s not someone else's problem, it’s everyone's.
So where to start? Let's first review my personal lifestyle, habits and patterns. The WWF Footprint calculator (a CTS customer!) suggests my family caused c14 tonnes in 2020 (no flights) and 29.2 tonnes in 2019 (12 flights) of CO2. When you think about that it’s crazy. There is a very large, scary and real physical aspect to this. Equivalence to elephants seems like a good metric, which I can just about visualise in my head.
2019 (29.2 tonnes)
2020 (13.8 tonnes)
Equiv 5 elephants!
Equiv 2.3 elephants!
However, to consider impact in a broader sense, thinking about my role and the type of company I work in, I wanted to understand how big the problem is and what CTS could do to contribute meaningfully to the resolution. That is beyond just making changes as a private citizen (which I firmly believe in, millions of people saving 14 tonnes each per annum is a very big number!).
A quick google search shows that globally we emitted 33 Gigatonnes of CO2 (I’m focusing on CO2, but acknowledge methane and nitrogen oxide are both factors here) in 2019, which is 33,000,000,000 tonnes. Yes it’s that big, too many elephants to consider big, but with all large problems, I find it easiest to break things down into smaller chunks which are easier to digest.
I started by thinking about a recent customer, they have circa 900 servers which we’re about to migrate to Google Cloud. The 900 virtual servers are in a colo facility, so this is impacting somewhere around 320kg * 900 = 288 tonnes to 916kg * 900 = 824 tonnes per annum. The range is due to the complexity of calculating the numbers e.g. how efficient was/is their current data centre, does it use ‘green’ electricity, what is the density of virtual to physical servers etc. The point is, it gives us some directional numbers to help frame the conversation. Fancy reducing your impact by 824 tonnes per annum - yes please!
If you then expand/extrapolate this across our customers, you can sketch out the type of impact CTS could have on this problem if we could persuade more of our customers to think big and accelerate their residual servers/applications to Google Cloud via our High Velocity concept. Now the numbers are approx, but I think directionally correct.

(this could be much higher, but decided it was a good conservative number)
# servers to be tackled

So what would the net impact be? Well using goclimate.com metrics again, we can safely assume using Google Cloud today as net neutral (i.e. they purchase 100% renewable energy + use of offsets) would be 50% improvement i.e. removing between 19,200 to 54,960 tonnes of CO2, as they move to net zero a full 100% improvement, which is remarkable + tangible.
In conclusion, I’ve enjoyed researching for this blog post and being able to put some directional targets on the potential impact we at CTS can make. We’ll see if the elephant equivalent metric gains international acceptance, who knows, but what I do hope is that it helps you to start thinking about you and your potential impact to start solving this problem of our generation.
