1. INTRODUCTION
BURVIX Sp. z o.o., company incorporated under number 0001131882, having its registered address at ul. Żurawia 43, lok. 8a, 00-680 Warszawa, Republic of Poland (hereinafter – “Company”, “We”, “Our”, “Us”) issues this Environmental Impact Policy (hereinafter – “Policy”).
Currently, the Company is registered as a virtual asset service provider (VASP) under Polish law and is preparing for transition to authorisation as a crypto-asset service provider (CASP) under Regulation (EU) 2023/1114 of the European Parliament and of the Council of 31 May 2023 on markets in crypto-assets (hereinafter – “MiCA”). Therefore, references to MiCA obligations in this Policy describe the Company’s alignment and readiness efforts, rather than current legal status.
This Policy establishes the Company’s internal framework for meeting these obligations. It sets out the methodologies, data sources, and sustainability indicators used for measuring and disclosing the environmental footprint of supported virtual currencies.
The Policy is designed in alignment with the following EU legal instruments, which together define the emerging framework for sustainability-related disclosures, in particular:
- MiCA – Article 66(5), which obliges crypto-asset service providers (CASPs) to make publicly available, in a prominent place on their website, information on the principal adverse impacts on the climate and other environment-related adverse impacts of the consensus mechanisms used by the crypto-assets in relation to which they provide services;
- Commission Delegated Regulation (EU) 2025/422 of 17 December 2024, supplementing Regulation (EU) 2023/1114 of the European Parliament and of the Council with regard to regulatory technical standards specifying the content, methodologies and presentation of information in respect of sustainability indicators in relation to adverse impacts on the climate and other environment-related adverse impacts (hereinafter – “Commission Delegated Regulation (EU) 2025/422”).
The Policy is reviewed and updated at least annually or upon any material change in network consensus mechanisms, the availability of sustainability data, or applicable EU regulatory requirements.
2. METHODOLOGY AND DATA SOURCES
The Company discloses sustainability indicators in accordance with Table 2 of the Annex to Commission Delegated Regulation (EU) 2025/422, which specifies the content, methodologies, and presentation of information on principal adverse impacts related to the climate and environment.
For each supported virtual currency, data is derived from publicly available, verifiable, and blockchain-specific sources, including but not limited to:
- Cambridge Centre for Alternative Finance (CCAF) – Bitcoin and comparable Proof-of-Work (PoW) network electricity models;
- Digiconomist Energy Consumption Index – benchmark data for PoW networks;
- Crypto Carbon Ratings Institute (CCRI) – electricity and emission benchmarks for Proof-of-Stake (PoS) networks;
- official network sustainability reports and foundation disclosures;
- technical documentation and white papers of the respective protocols; and
- empirical estimations using recognised methodologies:
- top-down economic modelling (for PoW chains, based on hashrate, hardware efficiency, and miner economics);
- bottom-up node-based modelling (for PoS and DPoS networks, based on validator counts and measured power demand).
Where multiple data sources exist, the Company applies a precautionary principle, adopting the most conservative (higher-impact) estimate to avoid underreporting.
Where precise figures are unavailable, the Company provides a best-effort estimate using transparent assumptions and clearly indicates such estimates in the respective disclosure tables.
