At W. Portsmouth, we are proud to announce a major milestone in our sustainability journey: we have partnered with Positive Planet as our first-ever carbon reduction and net-zero advisory partner.

This partnership marks the beginning of a comprehensive three-year programme to measure, manage, and significantly reduce our environmental impact. Working with Positive Planet, we have already completed an independent assessment of our carbon footprint and are now developing a long-term strategy focused on practical, high-impact emissions reductions across our operations, projects, and supply chain.
“We are proud to formalise our commitment to a more sustainable future through this partnership with Positive Planet. As a company rooted in delivering innovative and forward-thinking solutions, it’s vital that we take meaningful steps to reduce our environmental impact and lead by example in the construction and engineering sectors.”
– Glenn Marshall , W. Portsmouth
“We are thrilled to embark on a three-year collaboration with W. Portsmouth aimed at enhancing their environmental sustainability efforts. Our partnership will involve extensive analysis of their carbon footprint, alongside expert guidance to develop effective carbon reduction initiatives. Furthermore, we will support W. Portsmouth to magnify the positive impact of these initiatives to both internal and external stakeholders.”
– Stephen Henry, Co-founder, Positive Planet
As recognition of the progress already made, we are also delighted to share that W. Portsmouth has been awarded the Positive Planet Certified Bronze Award.
This independent accreditation is awarded to organisations that demonstrate genuine commitment to environmental responsibility and have taken measurable steps to reduce their carbon footprint. The Bronze Award reflects both the solid foundations we’ve laid and our ambition to go further.
We understand that real change is ongoing – and this is just the beginning. Our team is fully engaged in embedding sustainability into every part of the business, and we’re excited to share our journey with clients, collaborators, and the wider community.
We firmly believe that high-performing infrastructure and a low-carbon future can go hand in hand.
