The Frankfurt Faculty Blockchain Middle (FSBC) and INTAS.tech printed a research outlining a brand new method on the way to offset the CO2 emissions attributable to the Bitcoin community. The research outlines a two-pronged versatile carbon compensation mannequin, in keeping with Greenhouse Gasoline Protocol Scope 3 emissions, for buyers, asset managers, crypto exchanges, and custodians. With this method, events can modify their carbon offset technique over time in accordance with their corresponding enterprise mannequin specializing in both the variety of Bitcoins held or on the proportional community utilization in relation to the Bitcoin blockchain development throughout a selected time period.

Carbon Emissions of Bitcoin from an Investor Perspective
INTAS.tech, FSBC
Though it has solely existed for lower than 13 years, Bitcoin has had an eventful historical past. On the identical time, nonetheless, local weather change continues to grow to be an ever-increasingly pressing situation. The CO2eq emissions related to Bitcoin’s consensus mechanism, specifically proof-of-work (PoW), have been probably the most important criticisms of Bitcoin in recent times. Reconciling Bitcoin’s shortcomings and strengthening its function presents a major alternative to make Bitcoin a extra sustainable funding.
Exemplary outcomes check with the analyzed interval from September 1, 2020, to August 31, 2021. For an correct calculation of the carbon footprint of an investor, the scenario have to be thought of individually relying on the enterprise method of the corporate (i.e., easy investing, asset administration, crypto exchanges, or custodians).
Key outcomes of our research
- Bitcoin community electrical energy consumption: The upkeep of the worldwide Bitcoin community required 90.86 TWh and 37.97 MtCO2eq throughout the specified interval. Electrical energy consumption needs to be considered from a impartial perspective. What issues is the supply of the electrical energy that’s consumed. It’s key to differentiate between renewable sources of electrical energy and fossil fuels. We do that by considering the whole electrical energy combine of every nation to transform Bitcoin’s electrical energy consumption into its carbon footprint.
- For comparability, the latest estimate of the whole yearly carbon footprint of the world is 45,873.85 MtCO2eq. This leaves Bitcoin with a complete footprint of 0.08% of worldwide CO2eq.
- For the calculation of the carbon footprint from an investor perspective, we suggest a two-pronged mannequin. Relying on the enterprise mannequin or knowledge availability, firms can both give attention to the proportional community utilization in bytes in relation to the Bitcoin blockchain development throughout a selected timeframe (transaction-based community utilization) or on the variety of Bitcoins held for a selected interval (ownership-based community utilization).
- A median Bitcoin transaction has a dimension of 670 bytes on the Bitcoin blockchain, representing an estimated carbon footprint of 369.49 kgCO2eq. Given a value of USD 50 per metric tonne of CO2eq, the compensation of 1 common Bitcoin transaction prices USD 18.47. We are not looking for this determine to be misinterpreted: One transaction can switch single US {dollars} or lots of of hundreds of thousands of US {dollars}. Additionally, firms reminiscent of crypto exchanges mixture tens of hundreds of customers on a number of Bitcoin wallets and solely a small subset of transactions to the community could also be performed (e.g., each day web inflows or outflows). Evaluating the carbon footprint of Bitcoin transactions must be executed in a really cautious approach.
- Holding 1 Bitcoin over the analyzed interval of 1 12 months equals a carbon footprint of two.04 tCO2eq. Given a value of USD 50 per metric tonne of CO2eq, the compensation of holding 1 Bitcoin over one 12 months prices USD 102.20.
- Corporations may apply the above-mentioned approaches for transactions and proudly owning Bitcoins to compute their carbon footprint they then ought to offset. As talked about above, the precise enterprise mannequin must be thought of for such computations. Sooner or later, it may be anticipated that the outcomes of such computations will have to be verified and audited by specialised service suppliers.
Whereas Bitcoin itself may hypothetically be mined with 100% renewable, carbon-neutral power, this isn’t the case as we speak as miners are incentivized purely to optimize their profitability by protecting their price as little as doable. In accordance with the “polluter-pays” precept, it might appear pure for CO2eq to be offset by mining firms or mining swimming pools as they buy generated electrical energy for his or her operations (Greenhouse Gasoline Protocol Scope 2 emissions). Nonetheless, this assumption could be infeasible to implement and likewise falls brief in truth. Since all events that put money into Bitcoin, whether or not immediately by way of crypto exchanges or not directly via monetary merchandise reminiscent of Alternate Traded Notes (ETNs) or crypto funds, profit from mining operations and, thus, finally from their energy consumption.
Transaction-based method
Subsequently an method is required which determines the proportional accountability for Bitcoin’s CO2eq footprint primarily based on the utility stakeholders get pleasure from. Since Bitcoin mining has the operate of including new transactions to the blockchain, a quantifiable technique is required to calculate the CO2eq emissions of transactions. Subsequently, essentially the most correct method is figuring out the share of blockchain area used relative to the whole Bitcoin blockchain development (transaction-based community utilization). Determine 1 under illustrates the methodology used within the transaction-based in addition to ownership-based method.

Possession-based method
Nonetheless, this method would usually exclude many events who don’t have entry to their transaction-related knowledge. Moreover, as proven above, a good portion of Bitcoin’s utility is derived from its long-term macroeconomic mannequin; the shop of worth. For this example, we advise a calculation mannequin which focuses on the portion of Bitcoins held relative to Bitcoins in circulation for a selected interval (ownership-based community utilization).
On this vein, we see a chance for all buyers, asset managers, crypto exchanges, and custodians to step in, and take accountability for his or her related carbon footprint within the Bitcoin community. Right here, the target shouldn’t be restricted to demonstrating company social accountability (CSR) but additionally in creating added worth in making Bitcoin a extra sustainable funding concerning its carbon footprint.
Carbon Footprint Evaluation

Carbon Footprint Evaluation for the Iconic Funds Bodily Bitcoin ETP (ISIN: DE000A3GK2N1)
INTAS.tech in collaboration with the Frankfurt Faculty Blockchain Middle is making use of the Bitcoin Carbon Neutrality Funding Normal (BCNISTM) as introduced above to evaluate the proportional carbon footprint for Iconic Funds Bodily Bitcoin ETP (ISIN: DE000A3GK2N1) for Q2/2021.
Making use of the transaction-based carbon footprint calculation mannequin of the BCNISTM, the carbon emission was decided: Calculated carbon emissions equal: 37.60 tCO2 (Statement interval: April 15, 2021 — June 30, 2021)
BCNISTM: Calculation mannequin for figuring out the carbon footprint of monetary merchandise that embrace Bitcoin in keeping with Greenhouse Gasoline Protocol Scope 3 emissions. Extra data on the methodology is offered as a part of this research. This method permits buyers, asset managers, crypto exchanges, and custodians to anticipate and adjust to regulatory necessities regarding ESG standards just like the European Union’s Sustainable Finance Disclosure Regulation (SFDR) at an early stage.
Conclusion
Corporations may apply the above-mentioned approaches for transactions and proudly owning Bitcoins to compute their carbon footprint they then ought to offset. As talked about above, the precise enterprise mannequin must be thought of for such computations. Sooner or later, it may be anticipated that the outcomes of such computations will have to be verified and audited by specialised service suppliers.
