A former Welsh commissioner has defended her role in cancelling the controversial M4 relief road near Newport, arguing that environmental protection must take precedence over short-term economic gains. Speaking on BBC Radio 4’s Radical podcast, Sophie Howe – who served as Wales’ first Future Generations Commissioner from 2016 to 2023 – stated that “there are no jobs on a dead planet” when questioned about the decision to abandon the 14-mile (22km) motorway project.
Environmental Priorities vs Economic Arguments
Howe, a former Labour councillor and police and crime commissioner, explained that her role required her to scrutinise government decisions through the lens of long-term consequences. She argued that the proposed six-lane relief road conflicted with Wales’ seven core “wellbeing goals,” particularly those relating to prosperity and environmental sustainability.
“The questions I pose to the government are: can you explain how this decision aligns with the goal of a prosperous Wales, which emphasises a productive, innovative, low-carbon society?” Howe asked. “Because we’d be increasing carbon emissions.”
When challenged that reducing commute times could benefit economic productivity, Howe acknowledged the tension but maintained that environmental considerations ultimately outweigh immediate economic advantages. “Exactly that, and that is usually exactly what happens,” she said. “Which is why, in these situations, economy always wins and environment always loses. But in the long term, there are no jobs on a dead planet.”
Broader Impact on Road Projects
The M4 relief road cancellation was not an isolated case. Howe revealed that she had examined numerous pre-approved road-building schemes across Wales, applying similar wellbeing assessments that led to the cancellation of dozens of projects, including a proposed third Menai crossing.
In 2023, the Welsh government ultimately scrapped all major road-building projects after reviewing 59 schemes, approving only 15 smaller-scale developments. The government stated at the time that new projects would only proceed if they reduced carbon emissions, supported public transport, walking, or cycling, and helped adapt to climate change.
Howe noted that funds originally allocated to the £1.6 billion M4 project have since been redirected toward public transport initiatives, including the South Wales Metro system, which is nearing completion. Rail passenger numbers have reportedly increased by 19.1% for 2024-25, with an additional 9.9% projected for 2025-26.
Political and Legal Context
The decision to cancel the M4 relief road was made by the Welsh government in 2019 under First Minister Mark Drakeford. However, an inquiry commissioned by the government criticised Howe’s approach, with a planning inspector concluding that the economic need for the road outweighed environmental concerns.
The inspector’s report specifically criticised Howe, stating that her suggestion that the inquiry had not properly considered future generations legislation was “wholly unwarranted.” The report described the M4 scheme as “anything but short term,” calling it a “long-term solution to long-term needs.”
Howe acknowledged that she was “generally not popular” with drivers experiencing delays on the congested M4 corridor but defended her stance by highlighting social equity concerns. “25% of the lowest income families in this region don’t own a car,” she pointed out. “So are you saying you’re spending the entire government’s borrowing capacity building something that benefits only the already better off?”
International Influence and Ongoing Debates
Since leaving her role in 2023, Howe has observed growing international interest in the concept of future generations commissioners. She noted that the United Nations has passed a declaration on future generations, Gibraltar has established a similar commissioner position, and legislation focusing on intergenerational fairness has emerged in various countries.
While bills ensuring governments account for future generations’ interests are under development in UK and Irish parliaments, a proposal for a future generations commissioner was rejected by the Scottish Parliament in January. Meanwhile, some previously cancelled projects are being reconsidered – the Flintshire “red route” was revived in a proposed transport plan in 2025, and discussions continue about the third Menai bridge.
The Welsh government recently confirmed that a “focused review of options which could improve conditions on the M4 around Newport is progressing,” with the deputy minister for transport scheduled to update the Senedd on the matter next week.
Why it Matters
This ongoing debate over the M4 relief road represents a fundamental shift in how governments balance economic development against environmental sustainability. As climate change becomes increasingly urgent, Howe’s advocacy for considering long-term consequences – even when they conflict with popular infrastructure projects – reflects a growing global recognition that short-term economic gains cannot come at the expense of planetary health. The decisions made in Wales may well influence similar debates worldwide, as nations grapple with reconciling immediate transportation needs with the imperative to reduce carbon emissions and protect future generations’ prospects.
