MiCA Recital (7) — preamble

(7) The consensus mechanisms used for the validation of transactions in crypto-assets might have principal adverse impacts on the climate and other environment-related adverse impacts. Such consensus mechanisms should therefore deploy more environmentally-friendly solutions and ensure that any principal adverse impact that they might have on the climate, and any other environment-related adverse impact, are adequately identified and disclosed by issuers of crypto-assets and crypto-asset service providers. When determining whether adverse impacts are principal, account should be taken of the principle of proportionality and the size and volume of the crypto-asset issued. The European Supervisory Authority (European Securities and Markets Authority) (ESMA) established by Regulation (EU) No 1095/2010 of the European Parliament and of the Council (5), in cooperation with the European Supervisory Authority (European Banking Authority) (EBA) established by Regulation (EU) No 1093/2010 of the European Parliament and of the Council (6), should therefore be mandated to develop draft regulatory technical standards to further specify the content, methodologies and presentation of information in relation to sustainability indicators with regard to adverse impacts on climate and other environment‐related adverse impacts, and to outline key energy indicators. The draft regulatory technical standards should also ensure coherence of disclosures by issuers of crypto-assets and by cryptoasset service providers. When developing the draft regulatory technical standards, ESMA should take into account the various types of consensus mechanisms used for the validation of transactions in crypto-assets, their characteristics and the differences between them. ESMA should also take into account existing disclosure requirements, ensure complementarity and consistency, and avoid increasing the burden on companies.
