Nicolas Endress is the chief executive and founder of ClimEase, a Swiss-based software company providing a platform designed to help businesses comply with the EU’s Carbon Border Adjustment Mechanism.
From the start of this year, the EU’s Carbon Border Adjustment Mechanism (CBAM) started to impose additional tariffs on imports of carbon-intensive products – from aluminium and steel to cement and fertilisers.
Large industrial producers based in the European Union have been paying a carbon price under the EU Emissions Trading System (EU ETS), Europe’s carbon market, for nearly two decades. The CBAM – the world’s first carbon border tariff – extends that carbon cost to goods entering the bloc from abroad.
The logic behind the mechanism is that since EU-based manufacturers have paid for the carbon emissions created during their production of goods using the EU ETS, so too should all the other nations that make the same goods.
However, as companies begin to prepare for the cost side of the CBAM, many are finding that the biggest savings today do not necessarily come from switching to cleaner production. Instead, they come from replacing default emissions values with verified emissions data using EU-approved methodologies and independent verification.
Moving from the default values can significantly reduce their exposure to carbon tariffs even when verified emissions are not especially low.
That could potentially disadvantage relatively efficient producers that do not have access to accredited auditors. If exporters’ capacity to secure verified data is distributed unevenly, the system risks perpetuating inequalities.
Default values inflate exposure
The CBAM requires all EU importers to report the “embedded” carbon dioxide equivalent (CO2e) emissions – that is, the total amount of greenhouse gas emissions – associated with the imported goods.
They must then compute the actual carbon cost based on the supplier’s reported product-specific emissions data. If no such product-specific emissions data is available, importers must instead apply the default emissions values stipulated by the European Commission.

To evaluate emissions, manufacturers determine the total amount of fuel and other direct inputs used during the manufacturing process, such as the fuel burned during production at a steel mill.
These inputs are then converted into tonnes of CO2 using EU-approved methodologies. The results are subsequently verified by an independent expert who is accredited under EU rules. This verification process can be expensive and may be difficult to obtain in many developing countries.


CBAM also requires emissions from key precursor materials to be included. This means upstream suppliers’ emissions must also be calculated and verified. If they are not, importers must apply default values for those inputs.
Since these upstream processes can account for up to 80% of a product’s footprint, companies may still face significant exposure to default values even when their direct supplier’s emissions are verified.
EU’s new climate target lines up multibillion-dollar boost for carbon markets
These default values are in general very high and often represent the maximum possible emissions of the most polluting facility within a specific country or region. A highly efficient steel plant in, for example, India, Brazil or Türkiye, would be evaluated as if it was the least efficient plant in that region due to the lack of formally verified emission data which meet EU standards.
Equity at stake
Equity issues exist here as well. Developing-economy suppliers that have actually decreased their emissions will likely see no decrease in their CBAM costs if they have not had their improvements officially recognised by the EU.
However, obtaining third-party verification requires time, expertise and financial resources, which can present practical challenges for some suppliers – especially those with complex supply chains that require multi-stage verification.
EU importers will have to apply the default values when no verified data is available, leading to significantly higher carbon costs even when the manufacturing process is relatively efficient.

To address this imbalance, the EU could focus on expanding access to accredited verification, particularly in developing markets, while providing clearer guidance and standardised frameworks for emissions reporting across supply chains.
Improving recognition of credible local verification schemes and investing in digital reporting infrastructure would also help reduce reliance on conservative default values.
Without these adjustments, there is a risk that the CBAM rewards those best-equipped to navigate verification requirements, rather than those achieving the lowest emissions in practice.
In this new trade environment, data that proves efficiency – rather than low emissions alone – will determine which producers gain an advantage.

US pressure puts World Bank’s climate plan at risk
The World Bank’s work to tackle climate change is under threat as the Trump administration pushes the lender to ditch its green targets and step up support for fossil fuel infrastructure in the developing world.
With the World Bank’s key climate policy framework set to expire in June, closed-door negotiations between shareholders and the bank’s management over its successor have stalled, sources familiar with the discussions told Climate Home News.
This throws into doubt the future direction of the world’s largest provider of international climate funding to developing countries. Rajneesh Bhuee, just transition lead at campaigning group Recourse, said that scrapping the bank’s climate targets and markers would be “worrying”.
First introduced in 2021, the Climate Change Action Plan (CCAP) has driven an expansion in the World Bank’s funding for emission-cutting projects and support for vulnerable communities dealing with the growing impacts of climate change.
The plan embedded climate considerations across the bank’s lending practices and committed it to directing a defined share of its annual budget – now 45% – to projects with climate benefits.
Since the plan was introduced, the World Bank’s climate funding nearly doubled from $21 billion in 2021 to $39 billion in 2025.
Bessent attack on climate
That trajectory is now under threat. Since Donald Trump’s return to the White House, the US – the bank’s largest shareholder – has waged an aggressive campaign against its climate commitments.
US Treasury Secretary Scott Bessent said on Wednesday that the World Bank should abandon its “distortionary” climate finance target, claiming without evidence that it “undermines efforts to reduce poverty and spur economic growth”.
“We welcome the coming expiration of the Climate Change Action Plan, and upon its long-overdue expiration, expect the bank to immediately shift its myopic focus on climate,” he added in the statement issued during the World Bank’s Spring Meeting in Washington DC this week.
Earlier in the week, Bessent pushed back against the scientific consensus that human activities, and the burning of fossil fuels in particular, are the dominant drivers of global warming.
Progress called into question
With negotiations heading for a crunch, battle lines are hardening. Sources familiar with discussions told Climate Home News that European countries, backed by some Latin American nations and small island states, are holding firm in their push to see a version of the climate plan extended.
But nations reliant on the production of fossil fuels, like Russia and the Gulf States, have sided with the US, they said. The decision will ultimately be taken by the bank’s management, led by Biden appointee Ajay Banga, but with powerful advice from the governments that make up the bank’s shareholders.
Jon Sward, environment project manager at the Bretton Woods Project, said that any watering down of the World Bank’s climate agenda would be damaging.
“Over the past decade until last year, the scope and depth of the bank’s climate work, though still imperfect, had been expanding. That feeling of progress is being called into question,” he told Climate Home News.
IEA slashes pre-war oil demand forecast by nearly a million barrels per day
Multilateral development banks (MDBs) led by the World Bank have been handed an increasingly central role in providing funding for climate action to developing nations, as many rich governments channel a large share of their climate finance through the MDBs.
MDBs accounted for over 40% of public international climate finance in 2022, the latest year for which data is available. Growing support from MDBs and shrinking overseas aid budgets in developed countries suggest their role is likely to have grown even bigger since then.
‘Imperfect’ plan better than no plan
The World Bank’s climate approach has faced repeated criticism. Activists accused the lender of relying heavily on loans and adding to the debt piles of vulnerable countries, and of inflating its climate finance numbers by overstating the real climate benefit of its projects.
But Recourse’s Bhuee, said that, despite its flaws, a weak climate action plan is still better than no climate action plan. “Imperfect as the current plan is, it provides a basis for accountability,” she added.
While experts do not expect an immediate drop in climate funding, the removal of formal targets could weaken internal incentives to prioritise climate projects and reduce transparency over how funds are allocated.
In the short term, it would give the US administration a big symbolic win in its wide-ranging quest to hollow out international financing for climate action and boost support for planet-warming fossil fuels.
Gas compromise
“The US strategy is to run out the clock,” an expert with knowledge of the discussions told Climate Home News. “It is using the June deadline to either get rid of the plan altogether or as leverage to extract concessions on a weakened climate plan in exchange for something else like funding upstream gas”.
The World Bank committed to stopping support for gas extraction projects in 2019, but that ban has been reconsidered since Trump’s return to office. Bessent said on Wednesday that the World Bank should support an “all-of-the-above” approach to energy, including gas, oil and coal.
“The US has outsized importance over the World Bank’s policy,” the expert said, “but it is incumbent on the European shareholders to show some spine here”.

Rising Gas Prices Make the Market Ripe for Electric Vehicles, but US Automakers Can’t Seize the Moment
If consumers want to switch to an EV, they’ll need to do it without federal incentives and with scant selection of affordable models.
Over the weekend, on a family trip in central Kentucky, I paid more than $4 per gallon for gasoline for the first time during our current price spike.

The Cherokee Rose, Georgia’s State Flower, Actually Has Nothing to Do With the Cherokee People—or the State
The flower comes from East Asia and symbolizes a story of memory, myth and displacement. Now, there’s a movement afoot to choose a new, native state symbol.
As Tony Harris walks through his garden, he stops beside a young sapling, its thin branches stretching upward into the early spring air. In a few years, he says, it will bloom with fragrant white flowers the size of a fist.
