The EU’s debate over new sources of budget revenue reveals a significant evolution in the role of environmental policy. Carbon pricing was originally conceived primarily as a mechanism to change behavior by making emissions more expensive and encourage investment in cleaner production. It is increasingly becoming a source of public finance. The European Commission’s proposed “own resources” for the 2028–2034 budget could generate around €66 billion annually. Among the proposals, the most politically viable appear to be a levy on revenues generated through the Carbon Border Adjustment Mechanism (CBAM) and a charge related to non-recycled electronic waste. The Commission estimates annual revenues of approximately €1.4 billion from the CBAM levy and €15 billion from e-waste. ETS revenues could add another €9.6 billion.
Carbon policy is increasingly acquiring a dual economic function. It affects the relative cost of producing and importing goods while simultaneously generating revenues that can be used to finance public expenditure. In effect, the same regulatory architecture that is intended to reshape markets is becoming part of the fiscal architecture that funds governments. As carbon-intensive activities become taxable or subject to emissions pricing, their environmental externalities become incorporated into economic decision-making. But once those mechanisms generate meaningful public revenue, governments also acquire a fiscal interest in their continuation. Environmental policy therefore becomes progressively embedded in the political economy of taxation. This is particularly significant for CBAM. The mechanism was developed to prevent carbon leakage and create a more level competitive environment between European producers and imports. If its revenues become an EU-level “own resource”, however, the border carbon price acquires an additional function: it becomes part of the financing mechanism of the European project itself.
FACS Perspective
A successful carbon policy should ultimately reduce the taxable activity it targets. The cleaner production becomes, the smaller the carbon base should become. Governments therefore face the unusual prospect of building fiscal systems around revenues that, if the policy succeeds, ought eventually to decline.
Environmental externalities are being transformed into measurable economic variables, those variables are being incorporated into trade and production costs, and the resulting revenues are increasingly being incorporated into government finances. Business must navigate an increasingly more complex environment than just a behavioral adjustment.
