Looking for practical ways to reduce the carbon footprint in construction? Then this blog should provide the insights you need to succeed.
The built environment accounts for around 38% of global carbon emissions [1], with concrete production alone contributing 7% of the world's total [2]. To put this in context, the entire nation of the UK has contributed 3% of the globe's carbon emissions since records began in 1850 [3], which highlights just how significant the construction industry's environmental impact truly is and where forward-thinking contractors can make a real difference.
At Nationwide Concreting, we're committed to improving sustainability. Below, we explore six effective methods to reduce emissions in construction and explain why this change matters.
High carbon emissions are resulting in global warming, with a worldwide rise in temperature of 1.5°C already recorded [4]. This has impacted people, wildlife, and the planet, leading to the UK government setting out aims to prevent this temperature from rising further.
To achieve this, targets have been set to reach Net Zero construction emissions by 2050 (compared to 1990 levels) [5]. This includes reducing emissions by 68% by 2030 and 78% by 2035.
Given the construction sector's significant contribution to global emissions, reducing the carbon footprint in construction is essential if the UK is to meet these goals.
When discussing concrete's environmental impact, it's essential to understand two distinct types of carbon emissions. Embodied carbon refers to the CO₂ released during concrete production, from extracting raw materials through to mixing and transportation, which happens upfront before the floor is even laid.
Operational carbon, by contrast, accounts for the energy a building uses throughout its lifespan.
Here's where concrete offers a surprising advantage. Its thermal mass absorbs and releases heat slowly, which naturally regulates indoor temperatures and reduces heating and cooling demands over decades.
While embodied carbon is released immediately, these operational savings accumulate year after year, often offsetting a significant portion of the initial environmental cost.
The UK construction industry is moving rapidly toward mandatory carbon reporting, and contractors who track emissions early gain a clear competitive edge.
Developers and main contractors increasingly require detailed carbon data during the tendering process. Those who can demonstrate measured, verifiable emissions provide transparency that speeds approvals, satisfies planning requirements, and positions projects favourably for funding and certifications.
It's no longer just about compliance; it's about proving you understand the bigger picture and can deliver projects that align with modern sustainability standards.
Concrete contractors who embrace carbon tracking now will find themselves ahead when regulations tighten further. But what practical steps can be taken to reduce concrete emissions on site? Let's explore a few.
Reducing carbon emissions starts even before construction begins. At the design stage, a Life Cycle Assessment (LCA) can measure the environmental impact of a building across its lifespan. This includes repairs, energy use, and water requirements. Concrete flooring specialists can encourage designers and sub-contractors to integrate LCA into project planning.
Just as with financial budgeting, it's crucial to track emissions throughout a project. Reporting carbon outputs and using Environmental Product Declarations (EPDs) for materials allows contractors to identify high-emission areas and make informed choices to reduce the project's footprint.
Sourcing materials from local suppliers reduces transportation emissions while supporting regional supply chains and strengthening the local economy. It's a practical step that makes an immediate difference. However, always verify that these producers are themselves committed to reducing the carbon footprint in construction, as genuine sustainability requires accountability throughout the entire supply chain.
Transportation of materials and equipment can account for up to 16% of a project's emissions. Using renewable-powered machinery and biofuels, alongside reducing travel distances, can significantly shrink the carbon footprint in construction.
Incorporating recycled aggregates, such as crushed concrete, into new mixes can contribute to a 30% reduction in the carbon footprint of concrete when combined with Supplementary Cementitious Materials (SCMs) like fly ash or slag. While RCA alone primarily replaces natural stone, using it in an optimised mix design allows for a significant decrease in Portland cement without compromising target strength.
Contractors can assess sustainability using EPDs and adopt innovative, low-carbon alternatives. For example, PrimX jointless concrete flooring produces up to 70% less carbon emissions compared to traditional concrete, making it a powerful solution for reducing the carbon footprint in construction.
How much carbon is embedded in your concrete before it even arrives on site? The answer depends heavily on your supply chain.
At Nationwide Concreting, we audit suppliers to ensure they share our commitment to reducing emissions in construction, from raw material extraction through to final delivery. Logistics play a significant role here. Transportation accounts for a substantial portion of Scope 3 emissions, which covers all indirect emissions within a project's value chain, including materials, transport, and waste.
This is where local sourcing becomes genuinely impactful. By partnering with regional suppliers, we reduce haulage distances, cut fuel consumption, and lower the overall carbon footprint of every project, while maintaining the quality and performance standards our clients expect.
Want to reduce material use without compromising floor performance? That's precisely what our PrimX partnership delivers.
PrimX technology allows us to pour thinner concrete slabs without sacrificing load-bearing capacity or durability. Less concrete means less cement, which directly translates to lower embodied carbon. The jointless design eliminates the need for saw cuts and joint sealants, which reduces initial material use and long-term maintenance requirements.
Here's the operational advantage. Fewer joints mean fewer weak points where cracks can develop, which extends the floor's lifespan and reduces the carbon cost of repairs, resurfacing, or eventual replacement. It's a solution that reduces environmental impact both upfront and over decades of use.
Our low-carbon concrete flooring solutions directly contribute to multiple assessment categories. In BREEAM, this includes credits under Materials (Mat 01) for lifecycle impact and responsible sourcing, while LEED rewards embodied carbon reduction under Materials and Resources (MR).
Choosing concrete with verified lower emissions, recycled aggregates, or innovative systems like PrimX provides the documented environmental performance that assessors require.
We supply the technical data and Environmental Product Declarations (EPDs) needed to support your submission, which helps architects and developers secure the certifications that enhance project value and reduce the carbon footprint in construction.
Reducing your carbon footprint in construction isn't just environmentally responsible, it's financially strategic.
Carbon-efficient concrete floors deliver measurable cost savings throughout a building's lifecycle. Lower embodied carbon often correlates with optimised material use, which reduces initial procurement costs. Durable, low-maintenance finishes like polished or PrimX concrete minimise repair and replacement expenses over decades.
Looking ahead, carbon pricing mechanisms are tightening. As carbon taxes and levies expand, projects with documented lower emissions will avoid future financial penalties while positioning themselves favourably for green financing and incentives.
Key financial advantages include:
Reduced material and transportation costs through optimised specifications
