Cardano’s Sustainability Report: Meeting MiCA Standards

Energy Consumption and Carbon Emissions

Cardano’s Proof of Stake (PoS) network uses significantly less energy than traditional Proof of Work (PoW) networks. Its annual energy consumption is 704.91 MWh, much lower than Bitcoin’s energy consumption, which is equivalent to that of small countries.

Cardano’s annual carbon emissions are estimated at 250.73 tonnes of CO2 equivalent. Its carbon intensity, or emissions per unit of electricity consumed, is 356 grams of CO2 per kWh. This suggests a mix of renewable and non-renewable energy sources.

Waste Production

Cardano’s network generates 8.26 tonnes of electronic waste (WEEE) annually, of which 51.93% is not recycled. This highlights the need for improved waste management practices.

Natural Resource Impacts

Cardano’s operations require critical raw materials and water. Its energy consumption indirectly affects water usage, especially in regions where non-renewable energy sources are used.

MiCA Compliance

The CCRI’s report aligns with the MiCA regulations, which require crypto-asset service providers to disclose their environmental impacts. Cardano’s transparency in sustainability reporting sets an industry precedent.

Network Statistics

At the time of the report, Cardano operated 3,147 nodes, processed 19,530,055 transactions annually, and consumed 80.47 kW of power. Its power demand per transaction per second is 0.192 W.


The CCRI’s report provides valuable insights into Cardano’s environmental profile and its compliance with MiCA standards. As the crypto industry faces scrutiny over its sustainability, such assessments are essential for informed decision-making.
