The European Parliament’s Committee on Economic and Monetary Affairs (ECON) has voted against a controversial amendment that would have imposed a de facto ban on proof-of-work (PoW)-based crypto assets for companies operating in the European Union. Instead, lawmakers backed an alternative amendment tied to the broader regulatory framework for crypto assets under Markets in Crypto-Assets, or MiCA.
The decision is being seen as an important, if temporary, relief for the Bitcoin and broader crypto industry in Europe. While it does not end the debate around the environmental impact of mining, it signals that EU lawmakers are not prepared—at least at this stage—to pursue an outright restrictive approach toward PoW networks through MiCA.
Committee Votes Down the PoW Ban Amendment
The vote took place as ECON considered the MiCA framework, a major legislative effort designed to establish harmonized crypto regulation across the European Union. According to public reporting cited in the source material, a last-minute addition to the bill would have effectively prohibited PoW-based assets by introducing sustainability-related conditions that critics interpreted as unworkable for networks such as Bitcoin.
The amendment failed, with 23 votes in favor, 30 against, and 6 abstentions. For market participants and policy observers, that outcome was significant because it showed a clear majority in the committee was unwilling to endorse what many described as a backdoor ban on PoW.
At the same time, the broader MiCA draft advanced with 31 votes in favor, 4 against, and 23 abstentions. That distinction matters. The committee did not reject regulation of crypto assets; rather, it rejected one specific attempt to place strong restrictions on PoW within the wider MiCA package.
Patrick Hansen, head of strategy at Unstoppable Finance, described the result as a major relief and a political success for the Bitcoin and crypto community in the EU. His remarks reflected the mood among many industry participants who had viewed the amendment as one of the most consequential regulatory threats facing the European digital asset sector at the time.
Why the Amendment Drew Strong Opposition
Critics argued that the proposed language was not simply an environmental measure but an indirect attempt to make PoW-based crypto assets impractical or legally vulnerable within the EU. Because Bitcoin is the most prominent PoW network, opponents said the amendment could have had outsized consequences for the entire market, from service providers and custodians to investors and listed companies with digital asset exposure.
Before the vote, lawyer Jake Chervinsky warned that the MiCA PoW provision looked like a “pretext for a bitcoin ban.” He also argued that if regulators succeeded in targeting PoW first, the logic of the crackdown could later extend to proof-of-stake and other network security mechanisms. His comments captured a broader concern within the industry: that technical consensus design might become a moving target in future regulation.
For crypto advocates, the issue was therefore larger than mining alone. It touched on whether policymakers should regulate outcomes such as disclosures, market conduct, and consumer protection—or whether they should attempt to shape which blockchain architectures are acceptable in the first place.
Alternative Amendment Focuses on Sustainable Finance
Rather than adopting the contested PoW restriction, the committee supported an alternative amendment from European Parliament member Stefan Berger. The text does not impose an immediate ban. Instead, it directs attention toward the EU’s sustainable finance framework and future legislative evaluation.
Specifically, the amendment states that by January 1, 2025, the European Commission should present, where appropriate, a legislative proposal to amend Regulation (EU) 2020/852 in line with Article 10 of that regulation. The aim would be to consider including within the EU sustainable finance taxonomy those crypto-asset mining activities that contribute substantially to climate change mitigation and adaptation.
This approach represents a materially different policy direction. Instead of excluding PoW activities upfront, it leaves room for a future classification exercise tied to environmental performance and sustainability criteria. In practice, this means the EU is signaling a preference for further assessment and standards-based policymaking rather than immediate prohibition.
Berger described the result as a first-stage win for MiCA and suggested that acceptance of his proposal helps create a path for future crypto regulation. From a legislative perspective, the compromise may also help preserve momentum for MiCA itself by avoiding one of the most divisive issues in the package.
A Political Win, Not the End of the Debate
Despite the failed amendment, the discussion around PoW regulation in Europe is far from over. Hansen noted that the groups that lost the committee vote still had a procedural option available. They could attempt to block a fast-track MiCA process through the trilogue stage and push the matter to a plenary debate in the full European Parliament.
According to the source material, such a move would require support from one-tenth of the votes of the European Parliament, and that threshold was viewed as attainable by the groups seeking to continue the fight. In other words, the committee vote reduced the immediate threat of a PoW ban, but it did not eliminate the possibility of further institutional conflict over the issue.
That procedural backdrop matters for companies, investors, and policy teams monitoring EU digital asset rules. A committee-level defeat can be highly influential, but it is not always the final word in the legislative process, especially on politically sensitive topics such as energy consumption, climate targets, and financial innovation.
What This Means for the EU Crypto Market
For now, the most direct implication is that the EU did not move forward with a de facto committee-backed ban on PoW-based crypto assets. That will likely be welcomed by Bitcoin-focused businesses, miners, infrastructure providers, and firms with exposure to PoW networks. It also reduces the near-term risk that MiCA would become synonymous with a hard anti-Bitcoin stance.
At the same time, the vote underscores that environmental scrutiny remains central to Europe’s digital asset policy agenda. The supported amendment points to a future in which crypto mining may increasingly be assessed through the lens of sustainability reporting, taxonomy alignment, and climate policy integration. That could still produce meaningful compliance obligations or market distinctions over time, even without an explicit ban.
In that sense, the committee’s decision was both a victory and a warning for the industry. It was a victory because lawmakers rejected an immediate and highly controversial attempt to restrict PoW through MiCA. It was a warning because the broader policy conversation is shifting toward how crypto mining fits into Europe’s long-term environmental and financial governance systems.
As MiCA continues through the legislative process, the balance between innovation, market access, and sustainability will remain one of the most closely watched issues in EU crypto regulation. The ECON vote may have removed the most immediate threat, but it also made clear that the future of PoW in Europe will continue to be debated well beyond this stage.
