How MMC can decarbonise the UK built environment

The UK government will only achieve its net zero target by 2050 if the construction and property sectors embrace clean energy, improve efficiency and significantly cut the carbon emitted during construction and throughout a building’s life cycle.

From residential homes to commercial properties, the UK’s built environment is one of the country’s largest sources of harmful emissions, accounting for around 25 per cent of the UK’s total Greenhouse Gas (GHG) output. With climate deadlines approaching, urgent action is needed to reduce emissions and transition to a low carbon future – and MMC is the solution.

Cutting construction emissions with modular buildings

So, how much does the construction industry contribute to emissions? ONS data found that GHG emissions produced by the UK construction sector in 2024 were 30% higher than in 1994. For further decarbonisation, there must be a fundamental reduction in the carbon emissions from material production and construction activities, such as transport.

The answer lies in MMC. For example, modular construction utilises sustainable materials, such as timber, which has the lowest embodied carbon of any common modern building material. Our products also utilises recycled steel, which provides a green alternative to high-embodied-energy materials traditionally used in construction, like concrete and aluminium.

By combining these lighter-weight products with our offsite manufacturing techniques, we significantly reduce carbon emissions. Modular construction also allows all building components to be manufactured in a single location and transported to site, meaning that compared with traditional construction, modular buildings require far fewer vehicle movements, which not only lowers emissions but also benefits local communities and the surrounding environment.

Traditionally, a significant amount of a building’s embodied carbon is emitted before it even begins to be used. Modular construction limits unnecessary emissions by using precision, offsite manufacturing to reduce waste as components are made to exact specifications. As a result, fewer offcuts or waste parts are created.

Vitally from a circularity and sustainability standpoint, modular solutions are inherently reusable, reconfigurable, and recyclable. At Premier Modular, both our rental and permanent solutions can be routinely reconfigured to minimise the need for new components and modules in future. We specifically design our solutions to be easily installed, used, disassembled and redeployed many times over, creating a circular economy within our construction process.

Reducing a building’s energy use with sustainable modular solutions

This reduction in energy consumption can also be taken further to buildings themselves, with the implementation of low and zero carbon technologies.

Operational carbon refers to the emissions associated with the energy used to operate a building. These emissions are significantly reduced by increasing efficiency and embracing renewable energy sources. Fortunately, our precision manufacturing techniques create airtight environments that increase thermal efficiency, which means lower running costs and reduced carbon emissions. Also, modular solutions are easily fitted or designed with green technologies, ranging from solar PV panels to ground source heat pumps and rainwater harvesting systems.

For organisations, features like rooftop solar are not just about generating electricity. It’s about long-term financial security and resilience in an era of fluctuating energy prices. Recently, the UK government announced that rooftop solar installations on commercial properties would be exempt from business rates. This exemption carries through to 2035 and increasingly, many organisations are seeing rooftop solar as an essential asset, rather than an optional upgrade.

Modular building can help organisations and public sector bodies kick-start and accelerate their net zero journeys by delivering energy-efficient, low-carbon buildings from day one.
