What is the carbon emission reduction potential of active travel?

5 November 2018 ,

This blog was co-written by Dr Andre Neves, Delivery Planner - Active Travel, Transport for London, Dr Christian Brand, Associate Professor and Acting Director, Transport Studies Unit, University of Oxford and Dr Andy Cope, Director of Insight, Sustrans.

New research shows that, taking into account individual travel patterns and constraints, walking or cycling can realistically substitute for 41% of short car trips, saving nearly 5% of CO2e emissions from car travel. This is on top of 5% of ‘avoided’ emissions from cars due to existing walking and cycling.

We are all aware of the need to reduce carbon emissions. The transport sector is a particularly challenging area for carbon emissions. Transport is the only sector in the UK where carbon emissions continue to increase.

The most obvious solution to reducing carbon emissions is to encourage people to replace the trips that they currently make by car with walking and cycling trips. New research from the University of Oxford presents realistic, empirically derived evidence on the potential of walking and cycling to displace motorized travel and thus reduce GHG emissions.

Conducted by the iConnect research group, the study estimates the potential impact on carbon emissions of a shift from driving to walking and cycling in Cardiff.

Sustrans, supported by a grant from the Big Lottery Fund, completed more than 80 new, high-quality walking and cycling routes between 2009 and 2013. These schemes were part of the Connect2 programme. 

The routes were delivered with a range of partners and extended the National Cycle Network in communities UK-wide. Working closely with Sustrans, the iConnect study group used the Connect2 scheme in Cardiff as a case study area for their research.

We selected Cardiff as the natural experimental setting for this in-depth study, as the site was one of the larger Connect2 projects set in an urban area.

The Cardiff Connect2 Scheme consisted of five elements, including a new traffic-free bridge over the river Ely, opened in 2010, and improved link routes for pedestrians and cyclists (completed between 2011 and 2013) that increased connectivity between Penarth, Cardiff Bay Area facilities and Cardiff City Centre.

The aim of the scheme was to enable commuters to walk or cycle from Penarth into Cardiff (or the opposite way) and local residents to access the leisure and commercial facilities in the Bay and in Penarth without the need to travel by car.

The new paper reflects the lack of evidence at the micro level on the realistic, empirically derived potential of walking and cycling to displace motorized travel and thus reduce greenhouse gas emissions. The aim of this study was to investigate the potential for carbon emissions savings from replacing short car trips with walking and cycling and the extent to which high-quality infrastructure for walking and cycling may influence day-to-day travel decisions, change the spatial and temporal nature of local journeys and impact on overall carbon emissions from motorised travel.

In principle, short car trips are amenable to walking or cycling for most people. However, it is acknowledged that trip characteristics (mainly trip purpose and the complexities of daily travel) influence mode choice to a great extent (alongside built environment, personal and household characteristics). The study assessed the mode shift potential of short car trips by taking into account trip purpose and their complexity; for example, whether a short car trip was part of a tour/home-based trip chain, where a study participant was not the driver, trips that involved escorting to and from a place or shopping trips to large retail areas. Car trips exhibiting these characteristics are not considered to be easily switchable to walking or cycling.

In sum, 59% of journeys recorded by the study were less than 3 miles, and 49% of all car trips were less than 3 miles. The main reasons to drive a car over short distances included time constraints, convenience, need to carry heavy goods, giving a lift to passengers, escorting children or lack of feasible alternatives. Taking into account constraints around trip chains and trip purpose, the study found that walking or cycling could realistically substitute for 41% of short car trips, which is equivalent to 4.5% of all car trips.

How realistic are these figures?

Firstly, the 41% potential for mode shift can be considered a realistic, if conservative, estimate for typical car drivers. Different assumptions about what trips could be moved from cars to active modes lead to different outcomes. The study excludes the possibility of shifting any trips that are escorting (i.e. taking people to places they need to go to), being a passenger in a car and shopping to large retail outlets. If those were not excluded, the mode shift potential would increase to 69% of short car trips.

Furthermore, by taking a relatively conservative approach to the definition of short car trips (under 3 miles) the study may underestimate both potential and avoided CO2e emissions. For instance, if the analysis increased the threshold to 5 miles (which was well within the range of the study participants who cycled) the share of short car trips that could potentially be replaced would increase by 11.2%. So, on both counts, the estimates are conservative, and much greater savings are possible.

Is this enough to make a difference?

Climate change is a global problem. A change in travel patterns in Cardiff alone is not going to impact much in a global sense. But the research from Cardiff reflects changes that are possible in cities and towns throughout the UK, and in many cities and towns globally. As the only sector where emissions are increasing, if we could achieve a 5% reduction in levels of carbon emissions from transport, and achieve that fairly quickly, this would be a very positive step forward.

And as well as the considerable potential carbon emission reduction from these trips, when the wider environmental impacts of active travel, including ‘co-benefits’ of improved air quality, increased levels of physical activity, reduced noise and reduced fossil fuel use, the case for supporting walking and cycling is very compelling.

This exceptional trace fossil comes from the Westbury Formation, part of the Penarth Group, and dates to the Upper Triassic Period, approximately 208–201 million years ago.

Discovered by our team members Alister and Alison on 07 April 2025, this coprolite has been carefully cleaned, prepped, and treated by Alison, ensuring both scientific integrity and display quality.

Geological Context:

Fossil Type: Coprolite (fossilised faeces)

Likely Producer: Small Triassic reptile, possibly a fish-eating sphenodontian or early crocodylomorph

Inclusions: Clearly visible fish bones and scales preserved in matrix

Location: Aust Cliff, Bristol, UK

Formation: Westbury Formation

Group: Penarth Group

Geological Period: Upper Triassic

Depositional Environment: Shallow marine to marginal lagoonal setting with periodic terrestrial input – conducive to fossil preservation of organic-rich material like excrement

Notable Features & Scientific Importance:

This coprolite exhibits remarkable preservation, including bone fragments and fish scale inclusions, providing insight into the diet and ecosystem interactions of Triassic reptiles.

Trace fossils such as this are invaluable for reconstructing palaeoecological dynamics and food webs.

The Aust Cliff site is internationally recognised for its Triassic-Jurassic boundary exposures, yielding important fossils including marine reptiles, invertebrates, and trace fossils.

Palaeontological Classification (trace fossils): While coprolites are classified as ichnofossils (trace fossils) rather than body fossils, their morphological analysis and inclusions allow identification of likely producers and depositional context.

Ceratodus Fossil Coprolites – Upper Triassic – Aust Cliff, Westbury Formation, UK – Authentic Specimen

Ceratodus Coprolite Fossils in Matrix – Upper Triassic – Aust Cliff, Westbury Formation, Penarth Group, Bristol, UK

This listing features a genuine fossil coprolite specimen, attributed to the prehistoric lungfish Ceratodus, embedded in original matrix from the famous fish, reptile, and coprolite bed at Aust Cliff, near Bristol. This site is part of the Westbury Formation, a classic Upper Triassic locality in the UK known for its rich vertebrate fossil content.

Scientific & Geological Details:

Location: Aust Cliff, Bristol, England, UK

Formation: Westbury Formation

Group: Penarth Group

Age: Upper Triassic (~205–210 million years ago)

Depositional Environment: Lagoonal to marginal marine with periodic anoxic conditions—ideal for preservation of vertebrate remains and trace fossils

Fossil Zone: Part of the Rhaetian Stage, marking the transition to the Jurassic

Notable Species: Ceratodus was a genus of lungfish, a group that still survives today in limited forms. These fish were adapted to low-oxygen waters and left behind spiral or pellet-like faecal fossils.

Morphological Features of the Coprolite:

Typically cylindrical or spiral in form

Surface texture may show subtle spiral markings (if not abraded)

Matrix may contain associated microvertebrate remains including fish scales or bone fragments

Represents trace fossil evidence (not the animal itself but its biological activity)
