The Italian Minister said the Emissions Trading System (ETS) has a "perverse effect" and is condemning European companies from being competitive with other countries, urging other member states to back the suspension.

Italy's Industry minister Adolfo Urso urged the European Union to suspend its carbon market until the bloc presents a revised proposal due this summer, citing the hardship faced by European businesses because of high power and carbon costs.

The Emissions Trading System (ETS) is the bloc’s mechanism for making companies pay for their pollution, with the dual aim of reducing emissions and encouraging industry to invest in more sustainable alternatives.

In Europe, the ETS currently covers heavy industries, power plants as well as airlines and shipping. Additional sectors such as international aviation, landfills and incinerators will be included in the upcoming review by the European Commission.

But Urso said the ETS is to blame for Europe's competitiveness problems because the bloc's climate policy tool has a "perverse effect" and is preventing European companies from competing with China and the United States.

"We are all aware that the mechanism of the ETS, as it is currently drafted, is only a tax, a tariff on the energy-intensive companies that struggle to remain competitive," Urso told reporters on the sidelines of a gathering of industry ministers in Brussels on Thursday. “It is necessary - we are all aware - to review it in a substantive way."

"To do this properly, it is necessary to suspend the ETS mechanism while awaiting a reform that must necessarily be comprehensive," Urso added.

Urso added: "If we are in the face of the collapse of the European chemical industry and the crisis of European ideology, we cannot wait for the time of negotiations within the European Union to find a solution."

The Italian minister said that in the meantime, "we are looking for an effective organic solution," adding that he will ask the European Commission to suspend the ETS.

Italy's plea joins that of industry leaders who have recently asked the EU to urgently act to reduce energy and carbon costs. German Chancellor Friedrich Merz has recently touted the same idea, driving down carbon market prices, only to backtrack on it a few days later.

Nordic business leaders back ETS

In a letter sent to Commission President Ursula von der Leyen and EU Climate Commissioner Wopke Hoekstra, a group of Nordic industry associations representing Finland, Sweden, Denmark and Norway urged the EU to maintain the ETS, highlighting its role as a key European advantage and as a source of certainty for investments in clean technologies.

They backed the ETS as a "market-based and technology-neutral policy instrument" that helps reduce carbon dioxide emissions.

"Reforming the system must be done carefully, because it has such a significant impact on the economy and competitiveness, in addition to the climate," the Nordic leaders suggested.

The four industry associations argued that future prosperity in the EU is linked to the ETS since its revenues can bring about decisive investments in clean energy production, critical infrastructure, electrification, and ultimately the decarbonisation of industry.

"Efficient use of the EU's own resources is central to achieving almost all the Union's major strategic aims, and these efforts require reliable access to both public and private financing," reads the letter dated 23 February and seen by Euronews.

Since its inception in 2005, the ETS has slashed emissions by 39%, with revenues exceeding €260 billion, according to the EU data.

Hindering technological innovation

Carlo Carraro, President Emeritus and Professor of Economics at Ca' Foscari University of Venice, criticised the Italian government’s stance on the ETS, saying the attack risks weakening a policy that has proven effective in reducing emissions in regulated sectors.

"Innovation and competitiveness are now inextricably linked to decarbonisation," Carraro said. "Hindering the transition exposes businesses to increasing technological and financial risks and makes the country less competitive".

Similar thoughts were voiced by Chiara di Mambro, Director of Strategy Italy and Europe at the environmental think tank ECCO.

"Suspending the ETS as proposed today or subsidising gas, as envisaged in the Government’s recent decree, would move Italy in the opposite direction (higher energy prices): weakening the price signal, increasing market uncertainty, and ultimately delaying the transition away from expensive fossil fuels," di Mambro said.

Italy is already on track to overhaul its electricity market, which would strip carbon costs from power bills. Instead, Di Mambro suggests using fiscal revenues or dividends from energy companies to reduce the burden of levies on electricity bills.

 

‘This reform is a disaster’: Climate groups slam Germany for scrapping renewable heating law

A revision of an existing law will now allow homeowners to use oil and gas as heating fuel instead.

Germany’s government has drawn heavy criticism from environmental groups after it agreed to remove parts of a controversial law on heating homes.

The legislation previously stated that newly installed heating systems were required to use at least 65 per cent renewable energy - such as a heat pump.

The reform will now allow homeowners to use oil and gas instead.

One critic has called the move "an unconditional fulfilment of all the wishes of the fossil fuel lobby".

Germany scraps renewable heating mandate

The law on renewable heating sources was passed in 2023, and hailed by climate experts as one of the most ambitious goals of the centre-left-led government in power at the time.

But critics pointed to the challenges presented by rising inflation, with one newspaper calling the bill “Habeck’s heating hammer”, referring to the legislation’s author, Robert Habeck of the Green Party.

The right-wing, climate-denying Alternative für Deutschland slammed the law’s promotion of heat pumps, accusing the Green Party of “forcing” households to make costly interventions and removing their freedom of choice.

Germany’s government has now agreed to scrap the renewable heating mandate, as well as the requirement for expert consultation when installing a new system.

‘This reform is a disaster’

The centre-right Christian Democratic Union (CDU) maintains that the modifications to the legislation will still align with the target to cut CO2 emissions from buildings, among the major sources of planet-warming pollution, while giving households greater choice as to which technology to use.

Proponents say the legislation plans for a greater use of ‘green’ fossil fuels.

Economy Minister Katherina Reiche said homeowners would be able to choose sources including “hybrid models, biomass; yes, even gas and oil heating, but with an increasing proportion of biogas or bio-oil”.

The ‘green’ credentials of biomass and biogas are highly debated as their production and combustion can lead to significant carbon emissions and ecosystem damage.

Campaigners have accused the government of abandoning its climate goals - which include hitting net zero emissions by 2045.

"This reform is a disaster," Green Party parliamentary group co-leader Katharina Dröge told the German Press Agency (dpa).

"The CDU and SPD [Social Democratic Party] have today made it abundantly clear: climate protection is completely irrelevant to this coalition,” she added. “The federal government has abandoned the achievement of the climate targets."

The managing director of the German Environmental Aid Association (DUH), Barbara Metz, described the revised law as "an unconditional fulfilment of all the wishes of the fossil fuel lobby".

‘An enormously expensive gas cost trap’

Germany is the biggest greenhouse gas emitter in the EU, with the nation still relying on oil and gas for nearly 80 per cent of its heating.

Despite the promise to switch to ‘climate-friendly’ fossil fuels, critics have pointed to the scarcity and rising cost of sources like biomethane on global markets.

Dröge criticised the government of “driving people into an enormously expensive gas cost trap" with the legislation reform.

Heat pumps cost more than gas boilers to buy and install, but they are more economical to run.

Germany subsidises 30-70 per cent of the cost of a new heat pump, funding that will continue to be offered until at least 2029 under the revised law.

“Especially in light of Trump, global crises and fossil fuel dependencies, this [legislation change] is short-sighted and dangerous," Julian Joswig, a Green Party politician, wrote on X.


 

‘It’s a real New Zealand duty to save these birds’: Berry harvest brings hope for beloved kakapo

'We don’t have the Eiffel Tower or the pyramids, but we do have kakapo," says New Zealand Department of Conservation’s Deidre Vercoe.

The world’s only flightless parrot species was once thought to be doomed by design. The kakapo is too heavy, too slow and, frankly, too delicious to survive around predators, and takes a shamelessly relaxed approach to reproduction.

But the nocturnal and reclusive native New Zealand bird's fate is teetering toward survival after an unlikely conservation effort that has coaxed the population from 50 to more than 200 over three decades.

This year, with a bumper crop of the strange parrot’s favourite berries prompting a rare enthusiasm for mating, those working to save the birds hope for a record number of chicks in February, which would move the kakapo closer to defying what was not long ago believed to be certain extinction.

Kakapo live on three tiny, remote islands off New Zealand’s southern coast and chances to see them in the wild are scarce. This breeding season has launched one of the birds to internet fame through a livestreamed video of her underground nest, where her chick hatched on Tuesday.

Smelly parrots the size of small cats

The kakapo is a majestic creature that can live for 60 to 80 years. But they’re undoubtedly weird to look at.

The birds can weigh over 3 kilograms. They have owllike faces, whiskers, and mottled green, yellow and black plumage that mimics dappled light on the forest floor.

That’s where the flightless parrot lives, which has made its survival complicated.

“Kakapo also have a really strong scent,” says Deidre Vercoe, the operations manager for the Department of Conservation’s kakapo program. “They smell really musky and fruity – gorgeous smell.”

The pungent aroma was bad news for the parrots when humans arrived in New Zealand hundreds of years ago. The introduction of rats, dogs, cats and stoats, as well as hunting by people and destruction of native forest habitats, drove species of the country’s flourishing flightless birds – the kakapo among them – to near or complete extinction.

By 1974, no kakapo were known to exist. Conservationists kept looking, however, and in the late 1970s, a new population of the birds was discovered.

Reversing their fortunes hasn’t been simple.

Birds wait years or decades to breed

One reason the kakapo population has grown slowly is that its breeding is, like everything about the birds, peculiar. Years or even decades can pass between successful clutches of eggs.

A breeding season only happens every two to four years, in response to bumper crops of fruit from the native rimu trees the parrots favour, which last happened in 2022. A huge food source is needed for chicks to survive but it’s not known exactly how adult birds become aware of an abundant harvest.

“They’re probably up there in the canopy assessing the fruiting,” said Vercoe. “When there’s a large crop developing, they somehow tune into that.”

That’s when things get really strange. Male kakapo position themselves in dug-out bowls in the ground and emit sonorous booming sounds followed by noises known as 'chings', which sound like the movement of rusty bedsprings.

The deep booms, which on clear nights can be heard across the forest, attract female kakapo to the bowls. Females can lay up to four eggs before raising their chicks alone.

Since January, admirers of the birds have had a rare glimpse into the process through a livestream showing the underground nest of 23-year-old kakapo Rakiura on the island of Whenua Hou, where she has laid three eggs, two of them fertile. So precarious is the species’ survival that the eggs were exchanged for fake replacements while the real ones were incubated indoors.

A technician on 24 February replaced the fake eggs with the first near-hatching egg. The kakapo kept her distance while the switch was made but quickly returned to the nest, seemingly unperturbed. The chick hatched just over an hour later. The second real egg was expected to be added within days.

Native birds are beloved in New Zealand

Perhaps the only thing stranger than the kakapo is the lengths to which New Zealanders have gone to save it. Quadrupling the population over the past three decades has required their relocation to three remote, predator-free offshore islands and the micromanaging of the parrots’ every romantic entanglement.

“We do what we can to make sure we don’t lose any further genetic diversity,” Vercoe says. “We manage that carefully through having the best matches possible on each island.”

Each bird has a name and is monitored by a small backpack tracker; if a bird vanishes, they’re nearly impossible to find. With the kakapo still critically endangered, there’s little prospect of conservation efforts ending anytime soon, although those working with the birds are easing their hands-on management each breeding season.

The painstaking work to preserve the species might seem odd to outsiders, but the parrot is just one of many spirited and strange avians in a country where birds reign supreme. The only native land mammals are two types of bat, so New Zealand’s birds, which evolved eccentrically before human and predator arrival, have become beloved national symbols.

“We don’t have the Eiffel Tower or the pyramids, but we do have kakapo and kiwi,” Vercoe says. “It’s a real New Zealand duty to save these birds.”

What's the real environmental and financial impact of artificial snow?

Published on 

By the end of the century, all ski resorts across the Alps may be forced to use snow cannons, with dire consequences for local nature.

Could the 2026 Milano-Cortina Winter Olympics be the last held on natural snow?

The Games were widely hailed as a success, but also drew criticism for their heavy reliance on artificial snow: around 1.6 million cubic meters, according to the organisers.

That's roughly equivalent to around 640 Olympic-sized swimming pools.

Like it or not, rising winter temperatures could make artificial snow a non-negotiable necessity for future Winter Games — at least on the Alps.

Artificial snow keeps winter sports industry afloat

By the end of the century, snowfall across the mountain range, which spans eight countries, is predicted to decline by between 25% and 45%.

This is based on a joint study by King's College, the University of Oxford, and the University of Trento called "The snow must go on: Theorising the climate innovation conundrum in expiring industries".

Globally, the industry is projected to grow at an annual rate of 4.4% between 2025 and 2032. But researchers warn that by 2050, ski resorts below 1,200 metres may have to endure snow-free winters.

So far, the winter sports sector has seen off the threat and managed to stay in good health, also thanks to the use of artificial snow, much like the recent Winter Olympics.

According to the study, some 90% of Italy's ski resorts already rely on artificial snow, compared to 70% in Austria and 54% in Switzerland.

"Once seen as a temporary fix, technical snowmaking is now a structural necessity, enabling resorts to remain operational even in low-snow years," the study says. "The widespread adoption of snowmaking reflects the growing consensus that natural snowfall alone cannot sustain snow tourism."

One of the few exceptions in Italy is the ski resorts near the highest glaciers. For example, the Marmolada — at 3,343 metres — which is nonetheless projected to vanish by 2040.

What's the financial, energy and environmental cost of artificial snow?

The use of artificial snow may save winter holidays, but for the environment, it's a problem, scientists say.

Snow cannons need a massive amount of water to blanket the slopes with snow.

Covering just one hectare (or 0.01km²) with 30 centimetres of artificial snow requires around 1,000 cubic metres of water — roughly 20 backyard swimming pools.

The water is pumped from nearby rivers and lakes — draining local resources — or drawn from artificial basins, which is no less impactful, as it requires extensive land work.

By 2023, the industry created "142 such basins" in Italy alone, covering more than one million square metres.

On top of that, fake snow is also denser and harder. It melts more slowly, leading to soil compaction and delayed plant growth.

'Delaying a local problem while intensifying it globally'

Its carbon footprint is significant too: in Italy, for example, "electricity-related emissions from snow production alone amount to 24 kt CO₂ eq, projected to rise by 24% and 30% with +2°C and +4°C warming, respectively", according to the King's College, Oxford and Trento study.

Ultimately, the cost is not to be overlooked, ranging from €3.50 to €5 per cubic metre.

"Artificial snow making exemplifies the tension between short-term economic resilience and long-term environmental sustainability", tells Europe in Motion Juliane Reinecke, one of the study's authors.

"For resort managers, snowmaking is about survival. It is a rational and necessary adaptation to climate risk. But snowmaking raises long-term sustainability concerns: it is water- and energy-intensive and requires intensive snowmaking infrastructure".

"As temperatures rise, even more snow must be produced until even that may no longer be sufficient to guarantee season-long snow cover."

"Firms are incentivised to prioritise operational continuity and short-term resilience. Societies, by contrast, have to worry about long-term decarbonization and ecological limits. When adaptation technologies are energy- and resource-intensive, they may solve (or delay) one problem locally while intensifying it globally. That is the paradox we are trying to highlight".

In the past, forests around the world were cut down on a massive scale. We lost some of the world’s richest ecosystems, Our World in Data  (OWID) reports.

In recent decades, the picture has become more complex. Deforestation has not ended, but it is no longer happening everywhere. Since 1990, some regions have continued to lose large areas of forest, while others have slowed this long-run trend — and even reversed it.

The map shows regional changes in forest area based on the latest data from the Food and Agriculture Organization of the United Nations.

Deforestation has been particularly large in South America and Africa. At the same time, the forested area has expanded in Europe, North and Central America, and large parts of Asia.

These gains show that deforestation is not inevitable. When pressure on land falls, forests can return.

I previously wrote about why deforestation is happening, and what we can do to bring the long history of deforestation to an end.

Panama seizes control of strategic ports from Hong Kong’s Hutchison

Panama’s decision to assume control of the Balboa and Cristóbal container terminals marks a structural rupture in the governance of infrastructure that underpins roughly 5% of global maritime trade and about 40% of US container traffic.

The measure, executed following a Supreme Court ruling that declared unconstitutional the concession held by a subsidiary of Hong Kong-based CK Hutchison Holdings, has triggered legal threats, diplomatic protests and operational disruption, while opening a broader debate over legal certainty in one of the world’s most strategic logistics corridors.

The legal trigger was a January ruling by Panama’s Supreme Court annulling the concession contract under which Panama Ports Company had operated the Pacific terminal at Balboa and the Atlantic terminal at Cristóbal since 1997. Publication of the ruling in the official gazette on February 23 rendered the decision final. 

Within hours, the Panama Maritime Authority occupied the facilities under Executive Decree No. 23 of February 23 2026, invoking “urgent social interest” grounds to ensure continuity of service. The decree authorised temporary occupation of movable assets, including cranes, vehicles, software and information systems, while explicitly stating that no transfer of ownership was implied.

President José Raúl Mulino framed the measure as an administrative tool rather than expropriation. In a televised address cited by multiple outlets, he insisted that the state was merely using assets to guarantee uninterrupted operations until their value could be determined for subsequent actions. The distinction is constitutionally relevant: expropriation entails permanent transfer of title and compensation; temporary occupation maintains ownership while the state assumes operational control.

Despite official assurances, the transition exposed immediate operational fragilities. The Panama Maritime Authority disabled internet systems at both ports to allow incoming operators to install their own software platforms and to mitigate cyber risks. As a consequence, the terminals were unable to operate at full capacity on February 24. 

At Balboa, export and empty containers resumed reception between 07:00 and 22:00, but import containers were not being delivered. Refrigerated cargo remained connected to power supplies under monitoring to protect perishable goods. At Cristóbal, gates were temporarily closed, halting container ingress and egress.

Government officials, including Canal Affairs Minister José Ramón Icaza, argued that vessel movements had not been materially affected. He noted that two ships had departed Balboa prior to publication of the ruling and that Cristóbal faced an eleven-day window without scheduled container berthing. 

Nonetheless, exporters reported difficulty retrieving empty containers, and industry representatives warned that even short-term frictions could affect routes dedicated exclusively to Balboa, particularly for perishables.

To prevent paralysis, the Cabinet authorised transitional concessions worth $41.9mn. The Comptroller General endorsed Contract No. A-2002-26 with APMT Panamá, S.A. for $26.1mn to operate Balboa, and Contract No. A-2003-26 with TIL Panamá, S.A. for $15.8mn to manage Cristóbal, both for up to eighteen months. 

APMT Panamá is affiliated with A.P. Moller - Maersk, while TIL Panamá is linked to Mediterranean Shipping Company. Under the published terms, operators will pay a fixed annual canon of $7.5mn plus variable payments after deducting recoverable costs, alongside fees of 13.20 dollars per container movement and 6.60 dollars per vehicle discharged outside containers.

The Ministry of Economy and Finance projects that, over eighteen months, state revenues could reach up to $100mn, several times higher than returns generated under the annulled concession. Officials cite a Comptroller’s audit indicating that over 29 years the state received $483mn, allegedly resulting in foregone revenues of $853mn. 

Conversely, the company has initiated arbitration exceeding $1.5bn, a figure the minister characterised as detached from financial reality. Legal representation is being assembled, with notification deadlines in early March and proceedings potentially lasting years.

From the corporate perspective, the events constitute unlawful termination. Panama Ports Company stated that authorities entered the terminals and assumed administrative and operational control without coordination. CK Hutchison Holdings described the takeover as illegal and warned of risks to operational safety. 

Reuters reported that employees were threatened with criminal prosecution should they refuse to vacate facilities and were instructed not to contact the parent company. The conglomerate signalled possible recourse under investment protection treaties and before the International Chamber of Commerce, and it has not excluded action against third parties, including APM Terminals.

The dispute has acquired overt geopolitical dimensions. US President Donald Trump has repeatedly alleged Chinese influence over canal-adjacent infrastructure and threatened to “take back” the canal upon returning to office. Panama has consistently denied any Chinese control. Following the court ruling, Hong Kong authorities lodged a “stern protest”, while China’s Foreign Ministry spokesperson Mao Ning declared that Beijing would firmly defend the legitimate rights and interests of its enterprises. 

Bloomberg reported earlier this month that Chinese authorities had asked state-owned firms to suspend new project talks with Panama and consider alternative shipping routes, as well as intensifying customs inspections on certain Panamanian goods. 

Finance Minister Felipe Chapman stated on February 25 that Panama had received no official Chinese reaction and that Chinese participation in foreign direct investment and banking deposits remained relatively low compared with investors from the Americas and Europe.

Domestic political scrutiny has paralleled international reaction. Former president Martín Torrijos criticised what he termed an “unnecessary geopolitical dispute” and questioned the transparency of the transition, even while acknowledging that the outgoing concessionaire had not been an effective partner. He warned that terminating concessions without clear explanation could set precedents affecting institutional credibility. 

Labour considerations are similarly central: more than 1,200 workers are directly employed at the two terminals. Authorities reported over 526 employer substitutions at Balboa and more than 326 at Cristóbal within 24 hours, with agreements reached with two of four unions. Legislator Eduardo Gaitán argued that if transitional operators do not assume accrued benefits, the state must compel the former concessionaire to settle outstanding entitlements.

Sectoral analysts emphasise reputational risk. Jorge Barnett of Georgia Tech Panamá underlined that the country’s logistics brand rests on uninterrupted service, while business leaders stressed that a port operating below 100% capacity erodes confidence irrespective of legal justifications. Angel Sánchez Chiapeto of the National Logistics Business Council warned that “a ship at berth generates no freight”, highlighting the cost of even temporary inefficiencies.

In aggregate, the episode intertwines constitutional adjudication, emergency administrative action, commercial renegotiation and great-power rivalry. Panama seeks to demonstrate that judicial independence and executive enforcement can coexist with operational continuity. Whether the combination of temporary occupation, enhanced fiscal returns and international arbitration will consolidate or weaken legal certainty depends on the state’s ability to sustain uninterrupted service while defending its position in protracted legal forums.

 

Trains, trams and buses face disruption across Germany as 48-hour strikes begin on Friday

The two-day walkout is expected to plunge travel into chaos, affecting millions of passengers.

The two-day walkout is expected to plunge travel into chaos, affecting millions of passengers.

Travellers should prepare for severe disruption to public transport services across Germany starting on Friday.

Workers in the sector have announced a 48-hour strike as discussions over salaries and conditions stall, a union said.

The two-day walkout is expected to plunge travel into chaos, affecting millions of passengers.

Trains, trams and buses face disruption

The industrial action will affect local buses, trams and trains (U-Bahn) in towns and cities across Germany – including major centres like Berlin and Hamburg.

The disruption will begin early in the morning on Friday 27 February and is expected to continue into Saturday 28 February in several places, too.

Nationwide railway – S-Bahn, regional trains, and long-distance DB trains (ICE, IC) – air and road services are set to operate as normal, although travellers should prepare for potential ripple-effect disruption.

The strike was called by the Verdi union, which represents about 100,000 workers employed across 150 transport companies, to help push through annual negotiations.

In early February, a similar walkout crippled public transport across the country.

"Our colleagues urgently need relief – and employers need a clear signal that we are determined to fight for our demands," Verdi Deputy Chair Christine Behle said in a statement.

"Employers still don't seem to understand that public transport services cannot continue to function in the long term if we don't make decisive improvements to working conditions now."
