Welsh wildfires push Torfaen into world’s top carbon emission zones 2026

Key Points

• The Torfaen area of south Wales became the fourth country to emit carbon in the highest intensity per square kilometre on Earth in July 2026 due to wildfires, according to Save the Children, after analyzing data collected by Copernicus Wildfire Emissions Watch.
• Torfaen was only beaten by Annaba in Algeria (first), Ávila in Spain (second) and Malanje in Angola (third) in terms of emissions intensity of wildfires for the mentioned period.
• There was a huge fire outbreak near Blaenavon, which was described by the fire service as one of the biggest and most difficult cases in south Wales in recent times. The fire outbreak started on 19 July and went on for more than a month.
• About 20,952 children and young people aged under 19 reside in Torfaen, and they are just a part of the 15 million children worldwide residing in regions experiencing extremely unusual wildfire carbon emissions between early July and early August.
• Save the Children emphasized potential health threats posed by the smoke inhalation, extremely high temperatures and inability to be outside for children.
• Torfaen Council confirmed that it had no information about the mentioned Copernicus findings but admitted that there were elevated particulate levels at its

Wales (Wales Times ) August 22, 2026 – Torfaen, a county borough in south Wales, became one of the world’s most intense sources of carbon emissions per square kilometre in July 2026 after a series of wildfires, including a prolonged blaze near Blaenavon, burned across the landscape. Data from the European Union’s Copernicus Wildfire Emissions Watch, analysed by the charity Save the Children, placed Torfaen fourth globally for wildfire emissions intensity during the month, behind Annaba in Algeria, Ávila in Spain and Malanje in Angola.

The Blaenavon fire, which started on 19 July and continued for more than a month, was described by the fire service as “one of the largest and most challenging” incidents in south Wales in recent years. At its height, shifting wind conditions carried smoke for miles across the region, with residents reporting the odour as far away as uk/local/cardiff/">Cardiff, 30 miles (48 km) from the blaze. The incident, alongside other fires in the area, contributed to a major incident declaration that ultimately required military support.

How did Copernicus data classify Torfaen’s wildfire emissions?

The Copernicus Atmosphere Monitoring Service (CAMS), part of the EU’s Space programme, classifies wildfire carbon emissions by comparing them to historical averages for the same period between 2003 and 2025. For Torfaen, emissions during the assessment window were categorised as “extremely unusual”, the highest level on the scale. Save the Children’s analysis of the Copernicus data showed that between early July and early August, about 15 million children worldwide lived in areas with “extremely unusual” wildfire carbon emissions, with a further 11 million in areas where levels were “much higher than normal”.

In Torfaen alone, 20,952 children and young people under 19 were living in the area during this period, according to census-based population data cited by the charity. The charity said hot, dry weather, “supercharged by climate change”, fuelled hundreds of fires near densely populated cities and towns globally during the same timeframe.

What health risks do children face from wildfire smoke and heat?

Save the Children warned that children are among the most vulnerable to air pollution because their bodies, organs and immune systems are still developing. Children absorb more pollutants than adults as they tend to breathe faster, and fine particulate matter known as PM2.5 is associated with premature deaths in the general population. According to the World Health Organization, PM2.5 can cause and worsen diseases of the lungs, brain and skin, and has also been linked to cognitive impairment and memory loss.

Melanie Simmonds, head of Save the Children Wales, said:

“In Wales and across the world, children are breathing in smoke from wildfires, coping with extreme heat and losing the freedom to play outdoors because the air is no longer safe.”

She added:

“These conditions are not only frightening – they carry serious health consequences for children whose bodies and lungs are still developing.”

Lily, a 15-year-old Save the Children Youth Advisor from Wales, said:

“The extreme heat has made it so that I am too uncomfortable to sleep and my appetite has worsened greatly.”

Data published last month showed that 84% of children in Wales experienced extreme heatwaves in the first half of 2026, with more than 10 million children across the UK affected.

What did local authorities say about air quality and the Copernicus findings?

Torfaen council said it was not aware of the Copernicus findings and expressed uncertainty about the data or evidence used in the assessment leading to the reported rankings. The council acknowledged that prolonged wildfire events could negatively impact local air quality, particularly through heightened levels of smoke and particulate matter.

The council noted it operates ongoing air quality monitoring via a station in Croesyceiliog, Cwmbran. “While elevated particulate concentrations were recorded during the wildfire period, the monitoring station aims to provide insights into general background air quality rather than conditions at locations directly adjacent to the fires,” the council said.

Blaenavon councillor Janet Jones said smoke was “particularly severe” on 13 August, roughly three weeks after the initial outbreak. “There were significant worries about air quality and its effects on the elderly and those with respiratory conditions like emphysema and COPD,” Jones said. She noted that two weeks prior she had consulted with GP practice nurses who indicated no noticeable increase in patients with respiratory complaints, but cautioned that the situation “might change in the coming months”.

What actions are being called for by Save the Children?

Save the Children Cymru is calling on the Welsh Government to strengthen the resilience of essential services critical for children’s development and wellbeing in the face of the climate emergency, and to ensure that the voice and needs of children are at the heart of climate adaptation and resilience strategies in Wales. The charity said it is working with partners and communities in Wales to help prepare children and families for extreme weather, with a particular focus on low-income families who are being hit hardest by climate change.

At a UK level, Save the Children is calling on the government to protect children’s rights by showing credible climate leadership at home and abroad. The charity said policies such as fossil fuel expansion are incompatible with the UK’s international commitment to the temperature goal of 1.5°C and pose significant risks to children’s health and wellbeing. A report by Save the Children and the Vrije Universiteit Brussel last year found that 1.5 million children could be spared the consequences of experiencing unprecedented lifetime exposure to wildfires if warming is limited to 1.5°C.

Background to the Torfaen wildfire and emissions development

The Blaenavon wildfire ignited on Mynydd Garncchdy, situated between Abersychan and Blaenavon, and burned an area approximately the size of 300 football fields. The UK Government issued a national alert last week warning the public of a very high risk of wildfires nationally, amid hot, dry conditions that have characterised much of the summer. Data from the National Fire Chiefs Council shows that England and Wales recorded 1,132 wildfires between 1 January and 16 August 2026, with Natural England’s records showing over 240 reported wildfires across Sites of Special Scientific Interest in England alone.

Copernicus Wildfire Emissions Watch has been tracking global wildfire emissions since 2003, providing near-real-time data on the intensity of carbon emissions relative to historical baselines. The service’s classification of Torfaen’s emissions as “extremely unusual” reflects the scale and persistence of the fires in the county during July, a period when wildfire activity in parts of Africa and Asia was lower than in previous years, according to Copernicus’ global dataset.

Prediction: How could this development affect children, residents and policy in Wales?

The designation of Torfaen as a global hotspot for wildfire carbon emissions is likely to intensify scrutiny on local air quality management, public health preparedness and climate adaptation planning in Wales. For children and families in Torfaen and neighbouring areas, repeated exposure to wildfire smoke and extreme heat could increase the burden of respiratory conditions, particularly among those with pre-existing vulnerabilities such as asthma, emphysema and COPD. If future summers bring similar or more frequent fire events, schools and outdoor activity providers may need to adjust schedules and guidance to limit exposure during high-smoke periods.

At a policy level, the findings may strengthen calls for more robust integration of children’s health considerations into Welsh climate resilience strategies, including enhanced air quality monitoring near fire-prone uplands and clearer public health messaging during major incidents. The UK Government’s national wildfire risk alert and the deployment of military support in south Wales indicate that wildfire response is already being treated as a strategic issue; sustained pressure from charities and local representatives could push for longer-term investment in prevention, land management and community preparedness. If warming trends continue, the risk of “extremely unusual” emission events in Welsh counties could rise, with implications not only for local health but also for Wales’ contribution to national and international carbon accounts.
