ICC has written to European Commission Director-General for Taxation and Customs Union to call attention to the severe compliance challenges faced by companies during the first reporting period of the transitional phase of the Carbon Border Adjustment Mechanism (CBAM). While expressive full support for EU’s ambitious efforts to accelerate climate action globally ICC Secretary General John W.H. Denton AO underscores the imperative to ensure that the CBAM does not create unnecessary barriers to global commerce that in turn risk stoking trade frictions and undermining cooperative action to secure a net-zero future.

Mr Gerassimos Thomas
Director-General for Taxation and Customs Union
European Commission

Paris, 3 April 2024

Dear Mr. Thomas,

I am writing to bring to your attention the severe compliance challenges faced by companies – of all sizes and across a range of sectors – during the first reporting period of the transitional phase of the Carbon Border Adjustment Mechanism (CBAM). 

To be clear: we are fully supportive of the European Union’s ambitious efforts to accelerate climate action globally – and, moreover, recognise the potential challenge posed by carbon leakage given existing asymmetries in domestic policies. However, to be effective, we believe it is imperative to ensure that the CBAM does not create unnecessary barriers to global commerce – which risk stoking severe trade frictions and undermining cooperative action to secure a net-zero future. 

In this context, we are eager to work with you to address prevailing concerns related to the implementation of the CBAM which we believe can be resolved through detailed and constructive dialogue with international business. Of particular note, we wish to highlight the following challenges that have been raised with us by a broad spectrum of companies in recent weeks:

In view of these challenges, we would like to ask you for a dialogue to explore solutions to address these immediate concerns – as well as a range of other compliance issues that have been faced over the first reporting period. 

More broadly, we see a real risk of the CBAM fostering an uneven playing field for international commerce:  not only affecting the competitiveness of European businesses by increasing their administrative burden and resulting compliance costs – but also posing long-term risks to the integrity of the single market. Retaliatory measures by non-EU countries risk precipitating trade barriers that could further distort global markets – with small businesses likely to be most acutely impacted. Other countries are already starting to design their own CBAMs, with a different methodology, serving not only climate objectives but also protectionist interests. 

Given this macro- and micro-context, we see an imperative to ensure the CBAM is aligned with a trade policy that fosters fair competition and sustains the EU’s principles of open and fair trade on a global scale.

We, of course, appreciate the complexities involved with implementing a forward-looking mechanism such as CBAM – and hope you will see ICC as a genuine partner to achieve its effective implementation. 

I look forward to hearing from you. 

Yours sincerely,

John W.H. Denton AO
ICC Secretary General
