Climate and Environmental Impact Statement – OP Digital
Purpose and Regulatory Context
OP Digital is committed to transparency regarding the climate and environmental impacts associated with crypto-assets supported through its services.
This Statement outlines the principal adverse impacts on the climate and other environment-related factors associated with the crypto-assets supported by OP Digital.
Scope of This Statement
The statement focuses on environmental impacts that are directly associated with the consensus mechanisms used to issue the relevant crypto-assets. OP Digital does not operate or control the underlying blockchain networks.
Methodology and Assessment Approach
OP Digital relies on assessments of climate and environmental impacts which use a qualitative and quantitative approach based on:
- The type of consensus mechanism (Proof-of-Work vs Proof-of-Stake);
- Estimated energy consumption per transaction;
- Estimated greenhouse gas (GHG) emissions per transaction; and
- Other relevant environmental factors, including electronic waste, land use, and water consumption.
Assessments taken from relevant published white papers rely on publicly available data, including academic research, blockchain analytics, sustainability reports, and independent studies relating to the energy use and emissions profiles of major blockchain networks.
Information on Principal Adverse Impacts on the Climate and Other Environment-Related Adverse Impacts
(by consensus mechanism)
| Consensus mechanism | Energy consumption | Greenhouse gas (GHG) emissions | Other environment-related adverse impacts |
| Proof-of-Work (PoW) | High energy consumption due to computationally intensive validation processes | High GHG emissions, dependent on the energy mix used by network participants | Generation of electronic waste linked to specialised mining hardware |
| Proof-of-Stake (PoS) | Low energy consumption, as transaction validation does not rely on energy-intensive mining | Low GHG emissions compared to proof-of-work mechanisms | No material adverse impacts identified |
| Proof-of-Stake networks supporting stablecoins | Low energy consumption, dependent on the characteristics of the underlying distributed ledger | Low GHG emissions, dependent on the underlying distributed ledger | No material adverse impacts identified |
The information above relates to the consensus mechanisms used to issue and validate transactions on the relevant distributed ledger technologies. The figures and qualitative assessments are based on publicly available information and represent indicative estimates. Actual impacts may vary depending on network usage, technological developments, and the geographic distribution and energy sources of network participants. The crypto-asset service provider does not operate or control the underlying networks.
Mitigation Measures
While OP Digital does not control the operation of blockchain networks, it seeks to mitigate environmental impacts through the following measures:
- Preference for lower-impact networks: prioritising support for crypto-assets issued on proof-of-stake networks (such as Ethereum, Solana, and stablecoins) compared to higher-impact proof-of-work networks.
- Environmentally responsible operations: utilising energy-efficient IT infrastructure and data centres with sustainability commitments where possible.
- Client engagement: supporting corporate clients with ESG-aligned approaches to crypto-asset usage.
- Ongoing monitoring: regularly reviewing environmental impact data and updating disclosures as blockchain technologies and regulatory standards evolve.
Limitations and Disclaimers
- Environmental impacts associated with crypto-assets may fluctuate over time due to changes in network activity, technological upgrades, or energy sourcing.
- Energy consumption and GHG emissions data are based on estimates from third-party public sources and may not reflect real-time conditions.
- The environmental impact of stablecoins depends on the consensus mechanism of the blockchain on which they are issued.
- This Statement reflects information available as of February 2026 and may be updated periodically to reflect regulatory, technological, or market developments.
