Please describe your proposed solution
The world is facing the huge challenge of climate change.
- The global cost of climate change damage is estimated to be between $1.7 trillion and $3.1 trillion per year by 2050.
- This includes the cost of damage to infrastructure, property, agriculture, and human health.
- This cost is expected to increase over time as the impacts of climate change become more severe.
- The poorest countries in the world are at greatest risk from the economic impacts of climate change.

There is an increasing call from investors and consumers for brands to demonstrate that they are part of the solution and not part of the problem. Cardano is already a comparatively green blockchain and massively more green than any proof of work system.
There is a potential to extend Cardano’s lead and create clear and simple market differentiation by making it ‘The greenest blockchain in the world’. To do this Cardano could programmatically ensure that any greenhouse gas cost that was incurred would be offset by purchased carbon offset investment. This would be a simple, on chain promise that Cardano runs at net zero.
Understanding the stepping stones and cost to deliver that vision is the problem we are trying to solve. The fully costed approach could then be presented to the community. DReps, representing the community, could choose whether to support the proposal or not.
The potential payoff is
- a healthier planet
- attracts a new set of investors, DApps and community members
- a showcase for Cardano’s unique approach to liquid democracy
- simple differentiation for Cardano versus other blockchains
- growth of loyalty and sense of belonging to Cardano from the community
- a surge in positive publicity and attention for Cardano
- A showcase for the power of programmatic on chain promises with smart contracts that has the potential to carry across from the web3 to the web2 world. This is supportive of the message of ‘Blockchain done right’ and how Cardano is the next generation blockchain of choice.
It is anticipated that the benefits of running an ongoing on chain carbon offset scheme would significantly outweigh the costs.
According to the Crypto Carbon Ratings Institute
- Cardano is already energy efficient with its proof of stake model
- It has a total annualised electricity consumption of 704.91 MWh for the Cardano Network
- Total annualised carbon footprint of the Cardano network is 250.73 tonnes of CO2. The carbon intensity of the consumed electricity is 356g CO2 per KwH
- The marginal power demand per Transaction Per Second is 0.192 Watts
There are a range of Carbon offset providers. A UK based sample can be seen from MyCarbonPlan and Professional Energy They offer a range of approaches and price ranges from £6.50 to £20 and potentially even more. There is also potential for these figures to change over time.
Given this range the total cost to offset all of Cardano’s carbon footprint in 2023 would be
Low: 250.7 tonnes x £6.50 = £1629.55
High: 250.7 tonnes x £20 = £5014
To deliver on the solution there are a number of challenges that need to be overcome:
1. Evaluate the different potential providers of carbon offsets globally, and make a recommendation of which to use. This should balance considerations such as cost, reputation of the provider, and carbon capture efficacy.
2. Review pre-existing efforts in the space including relevant catalyst proposals e.g.Carbon offset DApp proposal and related work in the Cardano ecosystem
3. Propose a mechanism to take a validated measure of electricity consumption from the Crypto Carbon Ratings Institute. Ideally this could be done using an Oracle, though if this is not possible or presents too great a risk to Cardano, another mechanism could be proposed. Create the code that would enable this deliverable. Ensure fall backs are in place.
4. Propose a mechanism for making a payment to the selected carbon offset provider based on the electricity consumption indicated by the Crypto Carbon Ratings Institute and create the code that enables that vision. Ensure suitable fall backs are in place if there is a need to change offset provider.
5. Propose governance around the periodicity of review for payments. Should this be annual, every 5 years, or a promise forever for Cardano? The proposal should explore the benefits and risks with each approach and make a recommendation. A ‘forever’ promise is far stronger as a commitment and a way of securing hearts and minds than a promise for a year, that might be viewed as more transactional.
6. Conduct a detailed security audit of the code used to programmatically access the treasury to ensure any risks are managed.
7. Create a model of how future costs for carbon capture might grow with Cardano to allow better scenario planning.
8. Navigate the appropriate Intersect committees, working groups and interfaces so that the proposal can either be adopted or be put forward for a vote by the community so it can be adopted.
