Milford Haven tops list of UK’s most polluted ports
NEW analysis by Transport & Environment UK (T&E UK) has revealed alarming levels of air pollution from ships at UK ports, with Milford Haven, Southampton, and Immingham emerging as the top three for harmful sulphur oxides (SOx) emissions. The study highlights the urgent need for regulatory action to address the severe environmental and health impacts associated with shipping emissions.
The findings show that in 2022, just 472 ships visiting Milford Haven produced nearly 100 times more SOx emissions than all of Pembrokeshire’s 67,000 cars. This disparity is stark, given that Milford Haven had only half the ship traffic of Immingham, which ranked second, yet still managed to emit 50% more SOx. Southampton, ranking third, saw 46 cruise ships – representing a mere 6% of its total vessels – contributing more SOx than 200 container ships.
The top ten ports for SOx pollution, according to T&E UK, collectively saw 3,700 ships emitting 30 times more SOx than the one million cars registered in their respective local authority areas. This paints a troubling picture of the pollution burden borne by port communities.
In terms of nitrogen oxides (NOx), ships in the top ten polluted ports produced nearly 1.75 times as much NOx as the 970,000 cars registered in those areas. Southampton again topped this list, with its ships producing four times more NOx than all the city’s cars, half of which came from cruise ships. The scenario was similar for fine particulate matter (PM2.5), where Southampton also led, with ships producing half as much PM2.5 as a million cars, with cruise ships contributing significantly.
Ships not only release poisonous exhaust fumes but also discharge pollutant-laden wash water from exhaust gas cleaning systems, commonly known as “scrubbers.” This wash water, dumped directly into the sea, adversely affects marine life and exacerbates ocean pollution, a growing concern in the UK. Despite this, only a few UK ports prohibit such discharges.
T&E UK’s rankings were derived from an analysis of SOx, NOx, and PM2.5 emissions from commercial passenger and cargo ships docked at UK ports in 2022. The study included vessels mooring within a 1.5 nautical mile radius of a port’s main coordinates, with emissions compared to pollution from cars registered in the same local authority areas, based on data from the Department for Transport and Driver and Vehicle Licensing Agency.
T&E UK has called for the government to enact comprehensive policy and regulations to address air pollution and greenhouse gas emissions from UK shipping. The forthcoming refreshed Clean Maritime Plan is seen as a critical opportunity for action. Key recommendations include mandating zero-emission berths, implementing a shore-side electricity plan, charging ships for emissions while moored, and designating all UK territorial waters as Emission Control Areas. Additionally, a prohibition on scrubber wash water discharge is urged.
Jonathan Hood, UK Sustainable Shipping Manager at T&E, stated: “The awful levels of pollution revealed in this analysis demonstrate how the UK’s port cities are being choked by the harmful fumes caused by a shipping industry that, thanks to years of government inaction, has no impetus to change. The government has its last chance to chart a better course for the industry with the updated Clean Maritime Plan and it must not waste this opportunity. We need to see a rapid switch away from filthy fossil fuels, and ports must set binding targets to implement zero-emission technologies. These must include shore-side electricity, which would ensure ships can plug in at port and switch off their polluting engines.”
The Rt Hon. the Lord Deben, former Chairman of the UK Government’s Climate Change Committee, added: “It is disheartening to see the staggering levels of emissions from ships around UK ports, as revealed by T&E’s new analysis. There is an urgent need for stringent action from the government by prioritising stricter emissions control measures around UK territorial waters, increasing the use of shore-side electricity across ports, and prohibiting the discharge of dirty scrubber water into waterways. Without decisive action, the health impacts for residents and workers in port towns, not to mention economic costs, will continue to soar, leaving communities to suffer the dire consequences of inaction.”
The Port of Milford Haven said it was “working incredibly hard, inside our own business and with our customers, to reduce emissions and deliver an accelerated transition to a Net Zero future”.
A Port of Milford spokesperson said: “The Port of Milford Haven is the busiest energy port in the UK supporting Britain and Europe with vital energy and fuel. As custodians of the Milford Haven Waterway, our environment is very important to us. Sustainability is one of our core values and we are working incredibly hard, inside our own business and with our customers, to reduce emissions and deliver an accelerated transition to a Net Zero future.
“This year, the Port implemented a ‘Green Ship Incentive Program’ to provide discounted rates for ships that perform better in reducing air emissions. Milford Haven is one of the first UK ports – and the only one in Wales – to financially incentivise environmental improvements to ships.
“In addition, the Port is one of only a handful of UK ports to prohibit ships that use open loop scrubbers to clean exhaust emissions from discharging their wash water within the Milford Haven Waterway.
“The Port of Milford Haven supports the British Port Association’s rebuttal of the report produced by Transport and Energy (T&E) UK and question the methodology they have used to reach their conclusions. We are also disappointed they did not engage with us ahead of the report’s launch.
“The Port of Milford Haven has a pivotal role to play in delivering the UK’s Net Zero ambitions offering a whole energy cycle solution that will unlock accelerated transition while stimulating economic growth. Together with our customers, we are committed to a resilient, low carbon future and as a lead partner in the Milford Haven Energy Cluster we have documented a pathway to achieve this here: Milford Haven Waterway Future Energy Cluster – Delivering an accelerated transition to a Net Zero future – 2023 on Vimeo.”
The British Ports Association, which represents UK operators, said the report lacked critical context and industry research showed emissions from ports were a fraction of wider background emissions in most cities.
Mark Simmonds, the association’s policy director, said most of the industry had “ambitious” net-zero targets, which would have “a positive impact on air quality”.

Everyday spaces key to future of Welsh language
EVERYDAY use of the Welsh language must extend beyond classrooms into workplaces, communities and online spaces if it is to thrive, according to a new report.
The study, published by the Commission for Welsh-speaking Communities, highlights the need for greater investment in the social, cultural and digital environments where people live their daily lives.
The report, Cymraeg in every community: strengthening the Welsh language, focuses on areas where fewer than 40% of people speak Welsh. It examines how the language can become a more natural part of everyday life in these communities.
The Commission says that while education remains vital, it cannot carry the responsibility alone. Young people must have opportunities to use Welsh outside school, particularly in activities they enjoy such as sport, youth groups and cultural events.
Among its recommendations is the creation of a dedicated fund to boost Welsh-language content online, including support for young people producing digital media in Welsh.
The report builds on earlier work published in August 2024, which focused on areas with higher numbers of Welsh speakers.
Commission co-chair Dr Simon Brooks said: “To ensure Welsh is a national language that belongs to us all, its future as a community language must be secured in every part of Wales. We urge the next Welsh Government to act on these recommendations with ambition.”
Co-chair Professor Elin Haf Gruffydd Jones added that there is strong appetite to use Welsh, but a lack of spaces to do so.
She said: “More than half of Welsh speakers live in areas where fewer than 40% of people speak the language. Public policy must create the right conditions for Welsh to flourish in everyday settings, with real investment in the spaces where people spend their time.”
She also pointed to international examples, including the Basque Country, where communities have actively created environments for their language to be used naturally.
Cabinet Secretary for Finance and the Welsh Language, Mark Drakeford, said the Welsh Government remained committed to its target of one million Welsh speakers by 2050.
He said: “Significant progress has already been made, with 17 recommendations from the Commission’s first report implemented during this Senedd term. This latest report provides a strong foundation to build on that momentum.”
Entertainment
Huw Edwards criticises TV drama about his downfall
FORMER BBC news presenter Huw Edwards has issued a strongly worded statement criticising an upcoming television drama based on his fall from grace.
Edwards, who received a suspended prison sentence after admitting offences relating to indecent images of children, said the programme was produced without properly checking its claims with him.

The two-part drama, Power: The Downfall of Huw Edwards, features actor Martin Clunes portraying the former newsreader.
In a statement published in the national press, Edwards claimed those behind the programme failed to verify key elements of the story before filming began. He said producers only approached him for comment after production had already been completed, and even then retained editorial control over any response.
He also questioned whether contributors to the programme had been paid, suggesting the drama may not accurately reflect events.
Edwards said he had already expressed “deep regret and remorse” for his crimes during court proceedings, having pleaded guilty at the earliest opportunity.
He added that he found the offences deeply disturbing and offered a further apology, acknowledging that each image involved a real victim.
The former presenter said he is now working on his own account of the events, although progress has been slow due to ongoing health issues. He has previously spoken about long-term mental illness, which he said had worsened in the period leading up to his offences.
However, he stressed that mental health difficulties should not be used to excuse criminal behaviour.
Edwards rose to prominence as one of the UK’s most recognisable news anchors before his career collapsed following allegations of misconduct and subsequent criminal charges.
In September 2024, he was handed a six-month suspended sentence and placed on the sex offenders register for seven years. He was also ordered to complete a rehabilitation programme.
Responding to his criticism, a spokesperson for Channel 5 said the drama was based on interviews with those involved, including the complainant and journalists who broke the story, as well as court reporting and message evidence.
They added that the programme was produced in line with broadcasting regulations and that allegations featured in the film had been put to Edwards through his legal representatives in advance.

Benefits of breeding for wool quality explained as global demand rises
AS GLOBAL demand for sustainable textiles continues to grow, wool is presenting farmers with a renewed opportunity to increase revenue by improving flock quality.
Competition shearer and sheep farmer Matt Smith has been working for several years to enhance the value of wool from his Romney flock. However, he believes it could take another decade before he achieves the level of fleece quality needed to deliver a significant uplift in returns.

“We have invested heavily in genetics, particularly to improve micron density within the flock,” he said. “High-quality wool is in demand for premium, sustainable clothing, and better micron density combined with a higher comfort factor will always attract stronger prices.”
While his flock already produces wool that commands a good return, Smith believes there is further potential—particularly with the introduction of new technology that allows more precise measurement of wool quality.
“I have been fortunate to trial a new handheld device from Woven Optics, which measures micron and comfort factor in real time,” he explained. “It has allowed me to clearly see how breeding decisions are influencing wool quality.”
Developed in Australia, the Woven Optics device is designed for use in a range of conditions and has proven to be an accurate on-farm testing tool. In the UK, the company has partnered with Heiniger to bring the technology to farmers.
“I have been working with Hefin Rowlands from Heiniger to monitor our Romneys using the device,” Smith added. “While it represents a significant investment, it is small compared to what we already spend on genetics.”
He believes the technology offers farmers a practical way to track improvements and better understand how breeding choices impact wool value.
“It is an enabler,” he said. “Having the ability to test wool on farm in seconds could help shift the industry back towards prioritising wool as a key genetic trait.”
Smith argues that this shift is not just about profitability, but also about animal health and long-term sustainability.
“In recent years, breeding has focused heavily on carcass weight to meet market demand for larger cuts of meat, and wool quality has been overlooked,” he said. “That has had unintended consequences.”
Drawing on his experience as a contract shearer across the UK, Smith has observed a decline in fleece quality in many flocks.
“I am seeing more yellowing in fleeces and a stronger odour, which can increase susceptibility to fly problems,” he said.
He warns that neglecting wool quality may also be contributing to a growing reliance on chemicals, antibiotics and anthelmintics—raising concerns about resistance and animal welfare.
“As a sheep breeding nation, we risk forgetting how important wool quality is to overall sheep health,” he added. “Changes in fleece condition, combined with warmer temperatures, can increase flystrike risk. By breeding for better wool, we can reduce these issues and cut reliance on pharmaceuticals.”
Smith believes that embracing technology such as the Woven Optics device could help reverse current trends.
“Breeding in the wrong direction is not sustainable,” he said. “By improving wool quality, farmers can produce healthier, more valuable sheep. The tools are now available, and the opportunity is there to restore wool as a priority within UK sheep farming.”
