8. Measure and collaborate
- Carbon Crunch 11
“We have made huge strides in reducing embodied carbon since Carbon Crunch was launched 10 years ago and we are making progress every day,” said Mott MacDonald group managing director Cathy Travers. “However, measuring the effectiveness of our work is critical."
“We need to measure where we are at the moment and establish a baseline for us then to be able to identify where we’re going to get the greatest impact from the things we do and the greatest potential to reduce carbon.
“It is for that reason I was delighted to see the launch of the Built Environment Carbon Database – BECD for short – this autumn.”
BECD is a free to access carbon database for buildings and infrastructure, which is owned by the Building Cost Information Service, who are specialists in collecting, collating, analysing, modelling and interpreting cost information.
Benchmarking to improve
The BECD will allow precise calculation of the embodied carbon in all elements of a project, rather than an estimated single value for an overall project.
The move has been driven by criticism of the shortage of openly available industry data and of the lack of a clear “starting point” identified in the Is our Carbon Wallet Empty report, published in 2021 by Skanska with the Net-Zero Infrastructure Industry Coalition, which is chaired by Mott MacDonald.
Measuring the effectiveness of our work is critical.
“Mott MacDonald is proud to be the first company to share our proprietary carbon data through the database – with the full backing of our clients,” explained Cathy.
The BECD’s launch is initially focused on highway assets and uses a substantial body of infrastructure carbon data harvested from highways projects delivered by Mott MacDonald over the last seven years. Plans are in place to roll the database out to assets in the rail, energy and water sectors.
Mott MacDonald UK and Europe climate change lead Kim Yates added: “The plan is for the BECD to be expanded to other sectors in the built environment but, right now, the database allows you to look at the carbon cost of a typical roundabout, a flyover, and so on – rather than just a single figure for an overall project. It is that breakdown of the figures to a different level of granularity that differentiates it from other carbon calculators as it is based on built assets rather than predictions at design stage.
“By having a clear view of the current carbon cost, we can truly track the impact of carbon reduction measures taken at the design stage and compare them with industry norms. Using this data will aid design decisions to be made that enable our carbon reduction efforts to go further and faster.”
Data sharing needed
The BCIS, through its CEO James Fiske, is calling for others to share their data and give the database a broader range of data. He said: “The only way we can be sure that we are making the right decisions to reduce the environmental impact of our activities in the built environment, is to learn from and share data with each other.”
Using this data will aid design decisions.
Cathy continued: “To make BECD even more impactful, we ask for your support and that of every organisation in the built environment sector. We ask that you share your figures with the database too to make the benchmarking it delivers even more effective and accurate and better able to track trends.
“By sharing data, it will truly be possible to see how our designs measure up when it comes to moving the dial on carbon reduction. Getting to net zero is a shared responsibility and it would be really significant if everyone participates in the BECD initiative.”

The need for collaboration across the complete supply chain was identified as critical to the whole industry achieving carbon net zero by many of the speakers at the 2023 Carbon Crunch event. Mott MacDonald group external engagement director Denise Bower called on the sector to go further on joining forces and formalise that collaboration to share knowledge and remove siloed thinking.
6 objectives
14 member organisations
“Although we have come a long way over the last decade, we have much, much further to go and over the next 10 years we will need to go much faster too,” said Denise.
“As we’ve said repeatedly, the industry working together will be key and I would therefore like to invite you all to consider joining Mott MacDonald and other leading organisations as part of the Net-Zero Infrastructure Industry Coalition.”
The industry working together will be key.
Industry convenor
Formed in 2019, the coalition brings together a network of infrastructure businesses across both the private and public sector, along with academic institutions, to focus on resolving the carbon net zero challenge across the infrastructure industry supply chain.
The formation of the coalition was led by Mott MacDonald and came in response to the UK government’s legal commitment to achieving net zero by 2050. In forming the group, Mott MacDonald recognised that achieving the goal will require a profound transformation of the infrastructure systems that underpin society. Delivering this within 30 years required urgent action and a new level of collaboration.
From its launch with six partners, including Mott MacDonald, Skanska, Transport for London, Anglian Water, UKCRIC and the UK Green Building Council, there are now 14 organisations working within the coalition. The current membership now also includes including Pinsent Masons, Leeds City Council and National Grid. Opportunities to join the group are set to be expanded with new levels of membership.
Key objectives
The coalition had five key objectives at launch which remain central to its remit today:
- Support the government in providing and demonstrating leadership from across the infrastructure industry and inspire others to impartially help shape policy and guide its practical implementation
- Use our considerable resources to convene stakeholder groups and advise government on the delivery of infrastructure to achieve net zero by 2050 or earlier
- Support the development and implementation of regulation and standards by working closely with policy and standards setting organisations
- Provide regular communication and high-quality practical guidance on key aspects of achieving net zero in the infrastructure industry
- Managing working groups to develop guidance and organise impactful events and meetings to disseminate knowledge.
“Together we can continue to build the coalition's network of industry leaders, subject matter experts and academic partners,” added Denise. “Members are provided with the opportunity to influence project concepts in areas that are specific to their needs and make a significant impact on the UK's journey to net zero. So it is well worth becoming a member.”
In turn, the coalition ask that members provide feedback on developments in the sector, attend and contribute to select meetings, support projects and key areas of focus when practicable and enable the coalition's convening objective by facilitating relationships.
