Did you know the UK’s built environment is responsible for 42% of carbon emissions, 62% of waste and 50% of material use? These shocking statistics highlight why buildings, infrastructure and land use must be central to our approach to addressing the climate and biodiversity emergency.

Last night I attended the launch of Building Blocks, a manifesto to transform the Built Environment and turn a climate catastrophe into a climate opportunity. The climate emergency can often feel daunting and insurmountable. But it was truly uplifting to join experts focused on practical, implementable, and positive responses. Adopting optimistic, radical alternative approaches can turn waste and climate headaches into solutions to build a fairer, greener, and more prosperous planet.

Architects Declare —a movement of over 1300 architectural practices in the UK – are advocating for a more sustainable built environment. Their message is clear: our current approach to design and construction is not enough to address the urgent climate crisis. We must embrace fundamental change, aligning ourselves with regenerative models to secure a sustainable future for generations to come.

The evidence is undeniable. Despite three decades of sustainable design efforts, we are still far from meeting our climate goals.

Building Blocks is a bold vision for transformation, rooted in systemic change. It outlines practical steps to reduce carbon emissions, promote circular economies, and restore social and natural infrastructure. It’s a roadmap for creating a built environment that not only mitigates climate change, but also fosters thriving communities and ecosystems.

Key among these Building Blocks is the imperative to prioritise resource efficiency. We need legislation to limit embedded carbon emissions in construction (greenhouse gas emissions generated from producing and transporting goods), minimise carbon emission from buildings and align building standards with net zero trajectories (France has already done this). Business can support this and some do. Speaking at the launch Kevin McCloud, from Grand Designs, cited the case of a developer in the North West who builds to passive house standards and still make a decent profit. The more this type of development becomes the norm the quicker costs will come down too.

Local authorities also need greater powers to demand higher standards from developers. Westminster City Council recently unveiled a ‘retrofit first’ approach. It’s facing resistance from those used to traditional development, but it is worth persevering with.  A nationwide retrofit strategy would create around 500,000 jobs, a £300bn boost to the economy , and eliminate fuel poverty—all while reducing emissions from existing buildings. It’s good for the planet, and good for our pockets too. If every home in Manchester were retrofitted it would save £10bn in energy bills.

Transitioning to a circular economy is another vital component. Health, wealth, and wellbeing all improve in a circular economy. By reducing waste and maximising material reuse, we can not only cut carbon emissions but also stimulate economic growth, and protect natural resources. Financial incentives and removing VAT on retrofit would support this shift, encouraging businesses to prioritise sustainability. We need to make sure we are designing all buildings with deconstruction and the reuse of materials in mind.
