Carbon Fasting: A Glance at The Exact Potential Savings

Today, the focus is on savings potential in figures. To be more precise: What are the benefits of not drinking coffee and eating a vegan diet for my personal carbon balance? And: Do I even need a goal to save carbon?

Almost two weeks ago we started our Codyo internal carbon fasting challenge: While Kim saves carbon by cycling to work instead of driving, I reduce my consumption of coffee and animal products. So far so good. The carbon saving potential behind Kim’s “partial” car driving diet was quickly overlooked.

To be honest, I have not had an urgent need to know exacly how much carbon I could save through my project. For thr moment, the thoguht that it would have a positive effect was enough for me. Actually, that is enough for me now – at least to be motivated enough to pay attention to my daily consumption of the products I mentioned above. From the moent I made my decision, it (almost) works by itself.

However, I cannot escape from the numbers and I simply am too curious. I have to find out for myself what is behind the numbers. But how?

Carbon savings through vegan nutrition: How do I tackle the issue?

How do I approach the topic of vegan nutrition? I will click through a series of climate apps that I installed in the course of our market research to see what clues I can find there. The Klima Kompass seems to help. If I enter “low meat consumption” in the diet there, I end up with 1.33 t carbon equivalent per year.

Note: Further details for determining the value for eating habits are age, sex, fitness and regional/seasonal.

If I change to a vegan diet (all other information remains the same) the app spits out a value of 0.9 t carbon equivalent per year. Broken down to seven weeks this means a saving potential of 430 kg by 52 weeks times seven weeks – that’s almost 58 kg carbon saving. Not bad at all. In comparison: Kim could save about 25.2 kg carbon through his cycling to work everyday. So even if I’m not consistent… 😉

Carbon savings by reducing coffee consumption

Now on to the second project: Coffee. Another climate app, Carbon Trim, has, after some searching, a carbon value for coffee on offer. According to this, a cup of coffee without milk produces a carbon equivalent of 26 g carbon. What savings potential do I get for seven weeks if I reduce the number of cups to 3 out of 6 per day?

Six cups of coffee per day gives a good 1 kg per week, i.e. 7 kg in the planned seven weeks. I simply reduce the amount in half to get to three cups per day. Meaning I am pursuing a savings potential of 3.5 kg. Together with my vegan diet I could – if I am consistent – save 61.5 kg carbon in seven weeks. Again based on the average person who consumes about 1.5 t carbon in seven weeks, that would be a 4.1 percent savings potential. Also just a start!

But: That was not that easy. For me personally, it was also enough to know that I could make such a positive contribution – without being able to express it in numbers. What do you think? Could I have found that out more easily? What about you, do you need the exact values?
