Concentrations of methane are increasing over the UAE, a new study has revealed.
Levels are high in coastal areas, where there are landfill sites and sabkha habitats – mud flat or salt flat areas – both of which are key sources of the gas.
Inland, concentrations are high around the Hajar Mountains, where methane is thought to be emitted by farms and microorganisms that live in wadis.
The researchers at Khalifa University in Abu Dhabi behind the new study in Frontiers in Environmental Science used satellite data to calculate concentrations of the gas – which has the chemical formula CH4 – over the past few years.
They found that “column values” of methane, known as XCH4, were increasing by around nine parts per billion per year.
This was double the increase recorded over two other locations – the Arctic and Argentina – for which similar work has been carried out using satellite data.
Increasing population
Dr Diana Francis, an assistant professor in the earth sciences department at Khalifa University and the first author of the study, said that the increases in concentration were probably mostly the result of human activity “related to population growth and economic development in the region and globally”.
“Landfill sites and industrial sites in general are the most significant contributors to anthropogenic emissions and, therefore, they are the key sources to focus on when it comes to strategies towards net-zero targets,” she said.
A large proportion of the methane over the UAE may come, she said, from countries to the north, given that the prevailing winds are north-westerlies.
Methane is described as being 86 times more potent than CO2 at warming the Earth’s atmosphere over a two-decade period.
While CO2 retains its warming capacity for about 200 years, methane only remains for around nine to 12 years. As a result, measures to cut methane emissions can have a major effect on limiting temperature rises in a relatively short period.
Contributing to global warming
Scientists estimate that methane is responsible for around 0.5°C of the increase in temperatures experienced since pre-industrial times. This is just over one-third of total warming.
The UAE is among 150 nations to have signed the Global Methane Pledge – a commitment to ensure that methane emissions in 2030 are 30 per cent lower than in 2020.
Pledge organisers say that cutting methane emissions by 30 per cent by 2030 “could eliminate over 0.2˚C warming by 2050” .
Dr Francis said that cutting methane emissions required the implementation of regulations, the introduction of new technology and, across various sectors, efforts to minimise leaks, losses and emissions.
Methane-absorbing vegetation
Even in natural habitats that give off significant amounts of methane, such as the sabkha habitats, efforts can be made to reduce emissions.
These include helping to promote the growth of native vegetation, including plants adapted to high salinity, such as Salicornia.
“Vegetation acts as a sink for methane and can help reduce emissions by absorbing the gas,” said Dr Francis, who heads Khalifa University’s environmental and geophysical sciences laboratory.
Another way to reduce methane emissions is to avoid soil disturbance, as this can release stored carbon and trigger the production and release of methane, she added.
“By reducing methane emissions, we can help mitigate significantly the rate of global warming in the coming decades and its associated impacts, such as rising temperatures, extreme weather events and sea-level rise,” said Dr Francis.
The researchers behind the latest study are keen to see more measurements of CH4 levels taking place in the UAE.
This would help, for example, to distinguish between methane that originates locally and regionally, and between that caused by human activity and nature.
“This is very critical if we want to put in place effective measures and strategies for emission reduction,” Dr Francis added.
Other authors of the new study are based at Dubai Electricity and Water Authority and the Stevens Institute of Technology in the US.

Ten tax points to be aware of in 2026
1. Domestic VAT refund amendments: request your refund within five years
If a business does not apply for the refund on time, they lose their credit.
2. E-invoicing in the UAE
Businesses should continue preparing for the implementation of e-invoicing in the UAE, with 2026 a preparation and transition period ahead of phased mandatory adoption.
3. More tax audits
Tax authorities are increasingly using data already available across multiple filings to identify audit risks.
4. More beneficial VAT and excise tax penalty regime
Tax disputes are expected to become more frequent and more structured, with clearer administrative objection and appeal processes. The UAE has adopted a new penalty regime for VAT and excise disputes, which now mirrors the penalty regime for corporate tax.
5. Greater emphasis on statutory audit
There is a greater need for the accuracy of financial statements. The International Financial Reporting Standards standards need to be strictly adhered to and, as a result, the quality of the audits will need to increase.
6. Further transfer pricing enforcement
Transfer pricing enforcement, which refers to the practice of establishing prices for internal transactions between related entities, is expected to broaden in scope. The UAE will shortly open the possibility to negotiate advance pricing agreements, or essentially rulings for transfer pricing purposes.
7. Limited time periods for audits
Recent amendments also introduce a default five-year limitation period for tax audits and assessments, subject to specific statutory exceptions. While the standard audit and assessment period is five years, this may be extended to up to 15 years in cases involving fraud or tax evasion.
8. Pillar 2 implementation
Many multinational groups will begin to feel the practical effect of the Domestic Minimum Top-Up Tax (DMTT), the UAE's implementation of the OECD’s global minimum tax under Pillar 2. While the rules apply for financial years starting on or after January 1, 2025, it is 2026 that marks the transition to an operational phase.
9. Reduced compliance obligations for imported goods and services
Businesses that apply the reverse-charge mechanism for VAT purposes in the UAE may benefit from reduced compliance obligations.
10. Substance and CbC reporting focus
Tax authorities are expected to continue strengthening the enforcement of economic substance and Country-by-Country (CbC) reporting frameworks. In the UAE, these regimes are increasingly being used as risk-assessment tools, providing tax authorities with a comprehensive view of multinational groups’ global footprints and enabling them to assess whether profits are aligned with real economic activity.

Three tips from La Perle's performers
1 The kind of water athletes drink is important. Gwilym Hooson, a 28-year-old British performer who is currently recovering from knee surgery, found that out when the company was still in Studio City, training for 12 hours a day. “The physio team was like: ‘Why is everyone getting cramps?’ And then they realised we had to add salt and sugar to the water,” he says.
2 A little chocolate is a good thing. “It’s emergency energy,” says Craig Paul Smith, La Perle’s head coach and former Cirque du Soleil performer, gesturing to an almost-empty open box of mini chocolate bars on his desk backstage.
3 Take chances, says Young, who has worked all over the world, including most recently at Dragone’s show in China. “Every time we go out of our comfort zone, we learn a lot about ourselves,” she says.
