The rise of cryptocurrencies has coincided with the era where ESG movement has gained significant support. This has put cryptocurrencies, particularly Bitcoin and Ether, in the limelight due to concerns around carbon emissions resulting from high energy consumption. While the debate continues, we have partnered with Patch to measure and offset the carbon footprint of our portfolio so you can invest in Bitcoin or Ether without worrying about the environmental impact. Here is how we do it:
This number represents the amount of energy mining equipment use to generate a given amount of output (hash rate).
E.g. 0.1 Joules per Gigahash
We use the efficiency value from Step 1 and multiply with daily hash rate of the network to calculate total energy usage.
For this calculation, we answer two questions:
1) What is the distribution of mining activity?
- Country A: 40%
- Country B: 60%
2) What is the carbon footprint of each country?
- Country A: 10 tonnes of CO2 per MWh
- Country B: 5 tonnes of CO2 per MWh
Then we take the weighted average.
Once we know the energy usage of the network and how much carbon is emitted for that usage, we multiply them.
We allocate carbon emissions to our portfolio based on our daily holdings as a percentage of total supply.
- E.g. Holding 1% of total supply means we are responsible for 1% of the carbon emissions of the network.
We buy and expire carbon offsets for our share of emissions.
