New report identifies ‘gap’ in Britain’s transport decarbonisation journey

A new report has been published suggesting there needs to be a systemic shift in the way we travel if the UK is to achieve its net zero mobility targets. 

The study, Bridging the Gap, has been created by design and engineering company Stantec and research network DecarboN8. 

The research was carried out in collaboration with Transport for the North (TfN), Transport for Greater Manchester and Bury Council, as well as Leeds, Newcastle and Lancaster universities.

The report outlines a carbon ‘gap’ between what can be achieved by following current government transport decarbonisation policy and the meeting of these targets in a local planning context. 

It concludes that relying on a switch to electric vehicles alone will not be enough to meet transport decarbonisation targets and that people and place need to play a much bigger role.

Bridging the Gap suggests car use in the UK needs to be reduced by at least 20% by 2030.

There also needs to be more emphasis on creating places in which active travel, public transport or shared mobility systems are more attractive than cars, particularly for journeys between 5-30km.

The report demonstrates moves towards net zero mobility will require a move away from investing in ever greater capacity for car use. 

Instead, there needs to be a focus on creating more attractive places to live, work and play  where there is less need to travel, with convenient alternatives made available. 

Not only will this support the changes in travel behaviour we need to meet net zero mobility targets but it will also create healthier places to live. 

The study develops alternative, hypothetical ‘futures’ as a basis for the research based on TfN’s Future Travel Scenarios. 

Elton Reservoir and Northern Gateway in Bury, Greater Manchester provides a real-world geography for the study.

These futures assume major land use and transport transformation, each taking a different view about how the UK could meet its surface transport carbon outcomes. 

The study concludes that higher density, mixed use development, focused on improved public transport and active travel-friendly environments provides the most likely pathway to net zero transport outcomes.

A technology-led and mobility services-led future also has potential but would require even more ambitious reductions in car use.

Radical change and innovation would be needed to deliver either of these futures.

The report piloted Societal Readiness Assessments as a new approach to preparing the ground for the transition by examining how solutions and might need to adapt to align with societal needs.

This project was co-funded by Stantec, the Engineering & Physical Sciences Research Council, the Economic and Social Research Council and the University of Leeds. 

“What this research clearly shows is that we need radical change in our approach to development and infrastructure planning if we are to meet our net zero obligations for surface transport and create places where people want to live and work,” said Keith Mitchell, director of transport and place at Stantec and author of the report. 

“Vision-led planning is now part of our professional language and policy framework, but we are yet to develop the tools and techniques we need to deliver the shared, objectives-led visions that can begin to consistently deliver the changes that society needs.  

“We also need to offer alternatives that are truly easier than driving to help get children to school, to get people to work, to shops, leisure activities, and to hospital appointments.

"And, most importantly, we need to ask whether our alternative vision really meets the needs of society and be open to the changes this requires of us and our projects.”

Greg Marsden, professor of transport governance at the University of Leeds, added: “There is so much that needs to be done to change the practice of transport planning to really confront the challenge of keeping to 1.5C and to facing the increasingly evident tragic consequences of the changes that this level of ambition implies.

“And 1.5C seems increasingly difficult to achieve in the face of populist culture wars and a wavering commitment to the tough decisions that the Climate Change Committee state will define our progress.
