Achieving a genuinely sustainable transport future for the UK


WE ARE VERY PLEASED to record our holding of the first successful TAPAS Round Table event in association with the ‘Transport Thinking Forum’ , which addressed the theme of achieving a sustainable future for UK transport.

We were delighted with the response from our invited participants drawn from the TAPAS contributors and other professional colleagues who comprised 30 people bringing a range of perspectives and experience on this important subject. This lead to an excellent discussion and kick off what we hope to be a valuable ongoing professional exchange in events of this kind.

We are indebted to Professor Greg Marsden who provided a comprehensive introductory presentation in the first session, setting the scene with background information on the issues and challenges as addressed in a range of Government policy papers over the last few years. Greg gave these a forensic examination for inconsistencies and direct contradictions leading to the conclusion that there was not a genuine pathway to sustainability, and in particular net zero, in place.

He apologised for giving his talk the sombre title ’The death of sustainable transport?’, but said what he had been uncovering over the past year had lead him to the conclusion that we were in the last chance saloon for a truly sustainable transport system in the UK. There were still some great schemes, urban realm improvements and bike lanes for example, which were going to continue to help. But, Greg felt that structurally the country was now at the point of committing to a pathway of accelerated traffic growth and a focus on technology shift which would widen equity gaps, reduce the viability of public transport, and mean that it was set to continue a journey of managed decline.

‘More than this, in the thirty years I have been involved in transport planning we have dabbled with tackling congestion and decided not to’, Marsden said. ‘We have promised to resolve air quality and yet still not done so (and beware the as yet poorly understood problem of tyre and brake particulates)’. And now the Government was effectively committing to a policy under which transport would not be pulling its weight on climate change emissions, Marsden concluded.

His analysis of the recently published updated national Carbon Budget Delivery Plan pointed to the Government’s conclusion that “As outlined, our quantified proposals and policies give us over 100% of savings required to meet Carbon Budget 4 and 5 and 97% of the savings required to meet Carbon Budget 6… We are taking a market-led approach to developing and deploying the technological shifts required to meet net zero.”

Looking forward, Professor Marsden said a key next step would be to see the Committee on Climate Change’s response in its July Progress Review.

Whilst there was pretty much a committed pathway to electrification, without a credible timetable for an alternative pricing regime we would be planning for inequitable growth in travel demand.

If the Local Transport Plan funding envelope was essentially a flat line, it would mean being effectively consigned to no net reduction in CO2 emissions at the local level, if the past three decades were to be our guide. ‘Why would we expect more people to own cars, have lower motoring costs and decide not to use them?’ he observed.

Meanwhile, he worried how stable the public transport industry now was, with demand still 10-15% back in terms of the pre-Covid position. Previous ambitions now seemed unrealistic and the profession should not be deluding itself in imagining futures for which there is no real prospect of delivering, and perhaps acting as a cover for business as usual.

He challenged those transport professionals who didn’t think those outcomes were desirable to consider not going along with the narrative, but questioned if anyone with power was in a position to rock the boat — and wondered if the next Labour government would be any more amenable to a change of course.

As things stood, Marsden thought we were at the point of reading the final rights for sustainable transport.

Professor Greg Marsden was followed by four shorter contributions on various dimensions of the relationship of transport theory/policy and the practical issues of implementation. These were made by Nicola Kane, Director at Steer, on practical transport strategy delivery at local level, David Metz, honorary professor in the Centre for Transport Studies at University College London, on public attitudes to car ownership and expectations and prospects of behavioural change, Keith Mitchell, Director at Stantec, on the interface with the private sector, and Ben Plowden, the newly-elected Chair of the Transport Planning Society on the political dimension of policy-making.


Then after the break, there was a facilitated discussion under the ‘Chatham House Rule’ seeking to map out what those present considered to be the key determinants for effectively addressing the situation and achieving appropriate outcomes. Professor Peter Jones very capably drew the various threads together and challenged everyone present to contribute their thoughts. Whilst the relatively gloomy prognosis at the national policy level identified by Professor Marsden was widely recognised, some individual avenues for development were suggested, and some mechanisms discussed to challenge the Government and provide local exemplars of doing things differently — especially by the devolved UK administrations and regional/metropolitan transport authorities.

All in all, it was generally regarded as a very stimulating and productive event.

After the formal discussions, most of those present enjoyed an hour or so’s socialising in a nearby hotel bar.

No Safe Space for Decarbonisation: why we all need to know the tough changes transport must make
A significant decision just made by the Information Commissioner requires the Department for Transport to publish the assumptions behind the trajectories towards Net Zero that appeared in its Transport Decarbonisation Plan. The Freedom of Information request that led to the decision was made by Professor Greg Marsden. LTT invited him to explain his concerns, and the importance of the data now going to be released.
Reverse gear: The reality and implications of national transport emission reduction policies
Following his successful Freedom of Information application to obtain details of the Department for Transport’s assumptions about achieving Net Zero for UK Transport, Professor Greg Marsden has led a detailed analysis of that data, and other recent government policy documents. The results have just been published, revealing what the report sees as significant back-tracking on the original commitments. We invited Professor Marsden to summarise those conclusions, and add some further observations about what it all means for local transport
The route to Net Zero: DfT assumptions look well off course
Last month a Freedom of Information release was finally made by the Department for Transport with details of the calculations underpinning the Government’s transport decarbonisation plan. It followed Professor Greg Marsden having fought long and hard to get the information. From an initial look at the material, we asked him : what does it tell us?

Transport – not just carbon hungry
IT IS GENERALLY ACCEPTED that transport-related activity accounts for between 25-30 percent of global CO2 emissions, and the sector is not yet significantly reducing that very material effect on global warming. There is considerable data and research knowledge about the sector’s carbon footprint and contribution to climate change. This is normally related directly to its fossil fuel consumption. Alongside this, transport is also indisputably a very significant consumer of other finite material resources on the planet, yet very few figures are available for this part of its impacts.
A Year of Upheaval – but not much Progress
THE YEAR END is generally seen to be a good time to take stock. And for those interested in transport in the UK, perhaps this year, to draw breath and clear their heads too. Certainly 2023 has had more than its fair share of major twists and turns which leave us in a significantly different – and largely unexpected – place to where we were just 12 months ago.
Pandemic responses to travel-to-work seem here to stay - and have highlighted levels of car dependency
Changing journey to work patterns, and particularly the growth of working-from-home are an important issue for transport planners. New ONS survey results seem to confirm post-pandemic patterns are here to stay. John Siraut examines the new data, and continues his look at the 2021 England and Wales Census data related to patterns of car ownership and travel to work at the most fine-grained local level. He finds an underlying high level of car-dependency in most areas.
