The cost of travelling by train around Europe is four times more expensive on average than flying, according to Greenpeace.
The price differences stem from an uneven regulatory playing field at the expense of the climate and workers’ rights, the environmental group said.
Greenpeace compared ticket prices on more than 100 routes between major cities in European countries including the UK.
Many rail journeys on the continent were found to be twice as expensive as flying, despite there being direct routes between cities.
Flying was cheaper on all of the 12 routes from the UK that the team looked at, including between London and Edinburgh.
Travelling to Barcelona from London by train was found to be 10 times more expensive on average than flying, and up to 30 times more expensive if booked at the last minute – the biggest price difference in the analysis.
Greenpeace said travelling by train creates five times less pollution than flying, but on 79 of the 112 routes they looked at between 27 European countries, flying was cheaper.
“As millions of Brits head off on their European breaks – many to areas that are being scorched by this historic heatwave – the twisted economics of the transport industry means they are being encouraged to keep throwing fuel on the climate inferno," Dr Doug Parr, Greenpeace UK’s director of policy, said.
“Flying only looks like a bargain because the cost of pollution is so cheap. Low-cost airlines are paying negligible tax while imposing low wages and poor conditions on staff.”

Greenpeace called the UK’s 12 routes the “dirty dozen” and said train journeys cannot compete when a ticket to Barcelona from London costs as little as €12.99 ($14.53).
Swapping the 3.36 million annual flights on this route for train journeys would save approximately 461,000 tons (about 418,000 tonnes) of greenhouse gases, the group said.
They also said 3.4 million passengers fly between London and Edinburgh every year despite there being dozens of train connections every day.
Greenpeace wants the government to ban short-haul flights where there are viable rail alternatives, end subsidies for airlines and airports, phase out tax exemptions for kerosene and introduce a frequent flyer levy.
It is also calling for the introduction of “climate tickets”, which would allow travel on low-carbon forms of public transport in a country or region.
A separate analysis by the clean transport campaign group Transport and Environment recently found that the UK was missing out on £4.7 billion ($6.06 billion) in tax that it could be taking from the aviation sector.
“We’re committed to decarbonising air travel without the need to limit demand," a government spokesperson said.
“Our Jet Zero Strategy sets out our approach for net zero aviation by 2050, and recent reforms to air passenger tax means those who fly furthest, and have the greatest impact on emissions, incur a greater cost.”

Create and maintain a strong bond between yourself and your child, through sensitivity, responsiveness, touch, talk and play. “The bond you have with your kids is the blueprint for the relationships they will have later on in life,” says Dr Sarah Rasmi, a psychologist.
Set a good example. Practise what you preach, so if you want to raise kind children, they need to see you being kind and hear you explaining to them what kindness is. So, “narrate your behaviour”.
Praise the positive rather than focusing on the negative. Catch them when they’re being good and acknowledge it.
Show empathy towards your child’s needs as well as your own. Take care of yourself so that you can be calm, loving and respectful, rather than angry and frustrated.
Be open to communication, goal-setting and problem-solving, says Dr Thoraiya Kanafani. “It is important to recognise that there is a fine line between positive parenting and becoming parents who overanalyse their children and provide more emotional context than what is in the child’s emotional development to understand.”
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.
