Digital Services Act tops list of most lobbied EU laws with 15,000 amendments

The Digital Services Act attracted more than 15,000 amendments during its passage through the European Parliament, making it the most intensely lobbied piece of EU legislation in the past two decades. The figure comes from a POLITICO analysis of 5,000 legislative files tracked since 2004, using amendment counts as a proxy for lobbying pressure. The Corporate Sustainability Due Diligence Directive followed with just under 13,000 amendments, while the Artificial Intelligence Act, the Packaging and Packaging Waste Regulation and the Common Agricultural Policy Strategic Plans each drew between 8,000 and 10,000.

Amendments as a window into influence

Lobbying in Brussels is notoriously difficult to measure. The EU Transparency Register lists more than 14,000 organisations and individuals authorised to engage with the institutions, but it does not record which files they target or how successfully. Amendment tables offer a harder, if imperfect, indicator. Every amendment represents a legislative intervention, often drafted by interest groups, tabled by sympathetic MEPs, and negotiated in committee and plenary. The analysis shows a clear upward trend: the average number of amendments per bill has risen from one parliamentary term to the next, suggesting that the lobbying ecosystem has grown both larger and more systematic.

The methodology captures only the parliamentary stage. Influence exerted during Commission drafting, in Council working parties, or through informal channels leaves no comparable paper trail. Still, the volume of amendments correlates with files that involved multiple committees, high financial stakes, and organised campaigns from industry, civil society and national capitals. The top ten files share those characteristics.

Technology laws dominate the top tier

Four of the ten most amended laws belong to the digital package assembled under the first von der Leyen Commission. The General Data Protection Regulation, adopted in 2016 after a four-year fight, sits at number six with a then-record amendment count. It was the first file to draw the full weight of Silicon Valley's lobbying machines into Brussels. Google, Meta, Apple, Microsoft and Amazon built permanent, well-resourced operations in the Belgian capital during that battle, and they deployed them again for the Digital Services Act, the Digital Markets Act and the Artificial Intelligence Act.

The DSA, proposed in 2020 and agreed in 2022, sets obligations for very large online platforms on content moderation, transparency and systemic risk. It is now the legal basis for the Commission's investigation into X, the platform owned by Elon Musk. The Digital Markets Act, agreed the same year, gives the Commission powers to impose behavioural remedies and structural separation on designated gatekeepers. Both laws have drawn sustained criticism from the United States, including from President Donald Trump, who has threatened retaliatory tariffs over what he characterises as discrimination against American firms.

The Artificial Intelligence Act, proposed in 2021 and finalised in 2024, is the world's first comprehensive binding framework for AI. Even before it fully applies, the Commission has signalled it will propose targeted amendments to reduce compliance burdens, responding to industry warnings that the rules could stifle European competitiveness. That a law is being softened before implementation illustrates how the lobbying cycle continues after adoption.

Green deal files trigger corporate mobilisation

The Corporate Sustainability Due Diligence Directive, adopted in 2024, required large companies operating in the EU to identify and address human rights and environmental risks in their value chains. Nordic industry groups secured a delay to the Commission's original proposal in 2021. During the parliamentary phase, business associations argued the rules would create disproportionate administrative costs and legal uncertainty. Financial services lobbied successfully for a partial exemption. Within six months of the directive entering into force, von der Leyen announced a 'simplification' package that would substantially narrow its scope.

The Packaging and Packaging Waste Regulation, which entered into force in 2025, aims to reduce packaging waste per capita by 15 per cent by 2040 compared with 2018. The file generated such intense corporate lobbying that the Parliament's internal audit unit opened an investigation into allegations of abusive behaviour and security breaches linked to lobbyist access. The investigation remains a rare public acknowledgement of the pressure exerted on legislators.

The Just Transition Fund, adopted in 2021 to support regions dependent on carbon-intensive industries, attracted more than 7,900 amendments. The flashpoint was whether the fund could finance natural gas infrastructure. Several member states pushed for eligibility; the final text excluded it, but the amendment count reflects the political sensitivity of directing billions in cohesion spending.

Agriculture: the sector that rewrites its own rules

No sector mobilises more effectively in Brussels than agriculture. The CAP Strategic Plans regulation, the vehicle for implementing the 2021-2027 Common Agricultural Policy, amassed more than 8,700 amendments. MEPs attempted to reconcile the Green Deal's environmental ambitions, conditionality, eco-schemes, space for nature, with the income expectations of farmers and the political weight of rural constituencies. Many of the environmental safeguards negotiated in Parliament were subsequently diluted or removed after mass farmer protests across the EU in early 2024.

The Sustainable Use of Pesticides Regulation, a Green Deal flagship targeting a 50 per cent reduction in chemical pesticide use by 2030, drew nearly 10,000 amendments. Protections for sensitive areas such as schools and hospitals were deleted. Binding reduction targets were replaced with voluntary ones. The file collapsed under the weight of its own compromises; von der Leyen withdrew the proposal in February 2024. For the agri-chemical industry and the major farming organisations, it was a decisive victory. For the Parliament's green coalition, it was a demonstration of how amendment warfare can hollow out a law before it reaches a vote.

Budget files: where the money is

The regulation governing the EU's multiannual financial framework for 2021-2027 also features in the top ten. Budget negotiations are inherently distributional: every region, sector and interest group has a stake in the allocation of more than a trillion euro. The 2019 annual budget, though not in the top ten because it was split across multiple sub-files, also ranked highly. The next MFF, currently under preparation, will be shaped by new pressures: defence spending, the future of CAP conditionality, and the reform of cohesion policy for an enlarged Union. Lobbyists are already positioning for that fight.

What the numbers reveal about Brussels

The concentration of amendments on a handful of files tells a story about where power lies in the EU system. Technology, sustainability and agriculture are the three domains where regulatory choices create or destroy the most economic value. They are also the domains where the Commission has legislated most aggressively, inviting a proportional response from affected interests. The rising trend in amendment counts suggests that the legislative process is becoming more contested, more granular, and more dependent on the capacity to draft, table and negotiate thousands of textual changes.

That capacity is not evenly distributed. Large corporations, well-funded trade associations and law firms can generate amendments at scale. Smaller NGOs, consumer groups and academic experts often cannot. The result is a legislative record that bears the fingerprints of the best-resourced actors. The GDPR battle proved that civil society can win, privacy activists secured strong rights against a better-funded opposition, but the subsequent files show that industry has adapted, deploying larger teams earlier in the cycle.
