Regulatory delay for ships, Swiss suppliers under pressure

Context

In brief

• More than 170 states approved the draft Framework.
• The decision was postponed again: attention is now focused on December.
• Accelleron and Burckhardt Compression are feeling the pressure.
• ABB reports that customer activity is normal.

Key facts

• Objective → net-zero emissions by 2050
• First approval → April 2025
• Expected rules → large ships from 2027
• First postponement → October 2025
• New postponement → December
• Estimated emissions → approximately 2-3% of global CO2 emissions

The international decision

In April 2025, the more than 170 member states of the International Maritime Organization, including Switzerland, had approved the draft of a «Net-Zero Framework». The project aims to reduce the international maritime transport sector's net greenhouse gas emissions to zero by 2050. It also provides for a kind of CO2 tax on vessels and rules intended to apply to large ships from 2027.

Global shipping remains largely dependent on heavy fuel oil and marine diesel. According to the estimates cited in the source, it generates approximately 2-3% of global CO2 emissions. The development of the rules is therefore being monitored by Swiss suppliers that work with the sector.

The process was slowed by opposition from, among others, Saudi Arabia, Russia and the United States. After an initial postponement in October 2025, the decision was postponed again in early September 2026, this time until December.

Signals from Swiss companies

At the end of August, Accelleron, an Aargau-based turbocharger manufacturer, reported a setback in its annual outlook. The company explained that the postponement of the IMO net-zero regulatory framework had reduced short-term demand. CEO Daniel Bischofberger told the AWP news agency that he did not expect any changes in the short term.

According to Accelleron, operators of smaller and more economical ships invest little in sustainable propulsion without stronger regulatory pressure. Investments are continuing, however, for large container ships and gas carriers, which are also subject to regional rules and companies' climate targets.

Burckhardt Compression reports a similar effect: after the postponement of the Framework, investment decisions are being influenced more strongly by short-term profitability. The spokesperson for the Winterthur-based manufacturer explained the situation, while the group nevertheless considers the long-term trend toward efficient, low-emission marine propulsion systems to be confirmed. For ABB, customer activities are following the normal course of business, while the discussion is broadening from decarbonization to energy efficiency. The three groups agree on the need for greater predictability, stability and clarity regarding future rules; attention is now focused on the decision expected in December.

Operational details

What it means for Switzerland

The source focuses on Swiss suppliers and does not describe procedures for families or workers. The impact described is indirect but concrete: greater regulatory uncertainty changes when shipping operators decide to invest and is reflected in Swiss suppliers. The difference between segments and groups is the point to follow.

A market divided by type of ship

The table shows why a postponement does not amount to a uniform stop. For smaller and more economical ships, the absence of greater regulatory pressure translates into reduced investment in sustainable propulsion systems. For large container ships and LNG carriers, however, investments continue partly as a result of regional rules and companies' climate targets. The same regulatory phase can therefore create different pressures within the Swiss supply chain.

The case of Burckhardt Compression adds a second criterion: immediate profitability carries more weight in investment decisions. This is a different reading from ABB's, which describes customer activity as normal and notes that the discussion is expanding to energy efficiency. Accelleron, on the other hand, reports an impact already visible in short-term demand. The comparison does not make it possible to determine which company will achieve the best result: the source provides no data on orders, revenue, employment, wages or investments in francs.

The useful point of comparison for a reader is not to ask whether the transition has been abandoned. For Burckhardt Compression, the source says the opposite in the long term: the trend toward efficient, low-emission systems remains confirmed. The issue is the investment timetable and the different responses of customers to regulatory pressure. The December decision will therefore be the next reference point for the sector.

Key points

How to follow the December decision

For a Swiss reader, the most solid approach is to turn the postponement into a sequence of checks. The following procedure uses the elements that emerged in the dossier and helps avoid confusing the long-term objective with the immediate question.

1. Set the deadline

Consider December the next checkpoint. The timeline to note is: draft approved in April 2025; first postponement in October 2025; new delay announced at the beginning of September 2026. This reference serves to distinguish what has already been approved in draft form from what remains pending.

2. Identify the segment

When a new update comes out, ask yourself whether it concerns operators of smaller, more economical ships or large container ships and LNG carriers. In the first case, the source describes limited investment in the absence of regulatory pressure; in the second, it reports that investment is continuing because of regional regulations and companies' climate objectives. This distinction avoids applying the same assessment to the entire maritime transport sector.

3. Separate the short and long term

For Accelleron, the postponement reduced short-term demand; for Burckhardt Compression, decisions are more closely tied to immediate profitability. In the long term, however, Burckhardt considers the trend toward efficient, low-emission propulsion to be confirmed. ABB, for its part, reports normal customer activity and growing attention to energy efficiency. The comparison must therefore be updated without seeking a single label for everyone.

4. Assess what is missing

Do not attribute effects to the postponement that the text does not measure. The source does not indicate changes in wages, jobs, prices, taxes or the costs faced by Swiss households. If the next update does not add these data, the national impact will remain legible mainly through Swiss suppliers and their industrial prospects, not through a figure applicable to every resident.
