In a world where climate change is forcing us to review our industrial and commercial practices, the European Union is taking proactive steps to align international trade and environmental protection. The Carbon Border Adjustment Mechanism (CBAM), an ambitious and innovative initiative, embodies this approach.
However, faced with the protectionist measures of Donald Trump, re-elected in 2025, and his calls for reciprocity on environmental standards, the EU is considering changes to the MACF. Relaxations for SMEs, tighter controls for large companies, and other measures are being discussed as part of theOmnibus Simplification Package.
This article explores the foundations of the MACF, revealing the context, objectives and spirit behind this regulation. By demystifying this mechanism, we aim to shed light on its essential stakes, both for the European economy and for the global effort to combat climate change.
The concept of the Border Carbon Adjustment Mechanism (BCAM) emerged as part of Europe's ambitious Green Deal, aimed at making Europe carbon neutral by 2050. Recognizing the need to regulate not only domestic production but also imports, the EU conceived the MACF as a means of ensuring that domestic emissions reduction efforts were not undermined by products manufactured under less regulated conditions. Since July 2024, the MACF has entered a transitional phase, requiring accurate accurate reporting of actual emissions for importerswhile preparing for a definitive phase initially scheduled for 2026.
Faced with competitive pressures, particularly after Trump's election in 2025, the EU is proposing to postpone the purchase of certificates until 2027, simplify obligations for occasional importers, and tighten controls for large companies, as part of the Omnibus Simplification Package expected in late February/early March 2025.
Faced with the urgent challenge of climate change, the European Union has adopted proactive policies to limit greenhouse gas emissions. The MACF is integrated into the broader "Fit for 55" legislative framework, a set of proposals aimed at reducing greenhouse gas emissions by 55% below 1990 levels by 2030. This ambitious framework demonstrates the EU's commitment to achieving carbon neutrality, while underlining the crucial role of the MACF in regulating the environmental impacts of international trade. The "Fit for 55" must now adapt to potential deregulation in the USA, balancing emissions reduction and competitiveness through these envisaged flexibilities, which remain to be validated by the European Parliament and the Council of Europe.
Greenhouse gases, the main contributors to global warming, pose an existential threat to our planet. Increasing emissions are leading to global environmental catastrophes, such as extreme weather events, rising sea levels and loss of biodiversity. In the face of this urgency, it is imperative to rapidly and significantly reduce these emissions before it's too late. The MACF is part of the EU's response to this urgency, aiming to drive rapid global emissions reductions through innovative regulatory measures.
The Border Carbon Adjustment Mechanism (BCAM) is fundamentally designed to counter carbon leakage, a phenomenon in which CO2 emissions are shifted to countries with less stringent environmental regulations. By imposing a tax on the carbon emitted during the production of imported goods, the EU aims to balance the cost of carbon between products manufactured within the Union and those sourced from outside.
Þ This principle ensures that emission reduction efforts within the EU are not cancelled out by cheaper but more polluting imports, thus encouraging fair competition and supporting global decarbonization.
However, in response to international pressure, notably from Donald Trump, and the needs of European SMEs, the EU is proposing to reduce the scope of the MACF, excluding 90% of companies while maintaining 99% of emissions covered, according to
recent proposals of February 2025, which have yet to be validated by the European Parliament and the Council of Europe. This simplification includes a strengthening of control and supervision arrangements for the remaining companies.
MACF's objectives reflect an ambitious strategy to stimulate a global ecological transformation:
- Trade fairness: Guarantee fair competition by harmonizing carbon-related costs, while protecting European competitiveness in the face of protectionist measures by the USA, by postponing the introduction of certificates until 2027 and making it easier for SMEs.
- Reducing global emissions: Motivating global producers to adopt cleaner production methods, while keeping 99% of emissions from imports covered, according to current proposals, yet to be validated.
- Stimulating innovation: Encouraging the development and adoption of green technologies, despite the adjustments envisaged to reduce administrative burdens.
- Climate leadership: consolidate the EU's role as a leader, while adapting its standards to geopolitical challenges, such as those posed by Trump in 2025.
The implementation of the MACF aims to reduce global emissions by incentivizing producers to reduce their carbon footprint, even with planned relaxations. The tax is intended to bring about a widespread shift towards more sustainable practices, thereby increasing the chances of achieving the Paris Agreement targets. However, criticism is emerging over a possible dilution of these benefits, even though the EU maintains 99% of emissions covered, according to the February 2025 proposals, which have yet to be validated by the European Parliament and the Council of Europe.
The MACF is a key element in the European Union's strategy to combat climate change on a global scale. By taxing the carbon emitted in the production of imported goods, this mechanism aims to encourage industries outside the EU to adopt less polluting production methods. The initiative aims not only to reduce global carbon emissions, but also to encourage non-EU countries to strengthen their own environmental regulations.
In February 2025, the EU adjusts the MACF in the face of Trump, as set out above. These adjustments are designed to protect European competitiveness, but they are generating debate about their overall climate impact.
The MACF is profoundly changing the economic and commercial landscape, by equalizing the costs of carbon emissions between products manufactured in the EU and those imported. This policy favors companies that invest in reducing their carbon footprint, and could lead to a reconfiguration of global supply chains, with a preference for nearby or environmentally-friendly suppliers. However, recent relaxations could ease costs for European SMEs, but raise concerns for developing countries, whose exporters could be penalized by tighter controls, requiring greater EU support for a fair and equitable transition.
Despite its laudable aims, the MACF is not without its critics. Some analysts fear that the mechanism could be used as a protectionist tool that could distort world trade rather than serve climate objectives.
Others point to the risk of repercussions for developing countries, which may find it difficult to finance the transition to cleaner technologies.
The February 2025 proposals, including the postponement to 2027 and the exclusion of 90% of companies while maintaining 99% of emissions covered, are criticized as a step backwards for climate change, although the EU insists on its effectiveness.
These adjustments, still to be validated by the European Parliament and the Council of Europe, are sparking debate on protectionism and environmental efficiency.
The Border Carbon Adjustment Mechanism (BCAM) is a key initiative of the European Union to align trade practices with its climate ambitions. By taxing imports according to their carbon footprint, the EU encourages a global reduction in emissions and pushes global producers towards more sustainable practices.
Although promising, the MACF is giving rise to debate, particularly concerning its impact on developing countries, the risks of protectionism and, more recently, the risk of competitiveness for the EU in 2025, in the face of pressure from Donald Trump. Thus, the EU is adjusting its strategy in response to American pressure, raising questions about the true climate impact of these regulations.
It is crucial that the EU continues to engage in dialogue with all stakeholders to refine the mechanism, ensuring that it achieves its environmental objectives without imposing undue economic burdens.
