and specifying alternative materials, builders can help cut embodied carbon emissions by up to 50 percent, using solutions that are already cost-competitive and commercially available.
Understanding embodied carbon
Traditionally, sustainability in residential construction has focused on operational efficiency, or how much energy a home uses once it is occupied. While this remains important, it’ s only part of the picture.
Embodied carbon refers to the emissions created during the production, transportation, installation, maintenance, and eventual replacement of building materials. For new homes in particular, these emissions are often described as‘ frontloaded,’ happening before the homeowner moves in. As climate awareness grows, embodied carbon is playing a larger role in how construction professionals evaluate materials and approach sustainability.
How to ensure building materials are sustainable
There are practical steps builders can take to reduce a home’ s environmental impact through smart material choices. The tips below outline ways to evaluate, select, and specify sustainable building materials, without compromising on performance. whether they have signed up to any net-zero carbon goals, and if they have a clear strategy outlined to help them achieve their climate goals. Always verify the information they provide to ensure it is credible. Reviewing Environmental Product Declarations( EPDs) and Life Cycle Assessments( LCAs) can help builders understand a product’ s full environmental impact and make more informed choices.
Think about transport emissions
Using locally manufactured products where possible can cut transport-related emissions, as well as help support your local economy. For materials that travel longer distances, the method of transport also matters. Shipping by sea freight or rail typically produces far lower emissions per ton than road travel, making it a more carbon-efficient way of transporting materials.
Use wood where possible
Timber is one of the most widely used and versatile materials in home construction. When sourced responsibly, it is renewable, durable, and it stores carbon, helping reduce a home’ s overall environmental footprint.
Compared with alternative construction materials, wood is lightweight, simple
Source responsibly
It’ s important to understand where your materials come from. Responsibly managed raw materials help protect ecosystems and ensure long-term supply. For wood products, look for third-party certifications on their websites that verify wood is sourced from responsibly managed forests.
Beyond certifications, aim to partner with suppliers who are transparent about sourcing, production methods, and environmental commitments. Check
