The Construction-Climate Connection: Embodied Carbon in Landscaping Materials
In the world of sustainable construction and landscape design, conversations around carbon emissions are no longer just about what’s in the air – they’re increasingly focused on what’s in the ground. More specifically, the materials we choose for hard landscaping carry a hidden but significant carbon cost known as embodied carbon. Understanding and reducing this impact is becoming a crucial part of responsible procurement and landscape management.
What Is Embodied Carbon?
Embodied carbon refers to the total greenhouse gas emissions generated to produce a material – from extraction and processing to transport and installation. For landscaping, this often means the carbon footprint of stone, concrete, metals, bricks, aggregates, and even composite materials.
While operational emissions (like energy use on-site) can be managed with efficiency and renewable power, embodied carbon is locked in from the moment a product is made. That makes material selection an important lever for sustainability.
How to Evaluate the Carbon Footprint of Hardscape Materials
- Use Environmental Product Declarations (EPDs):
EPDs are third-party verified documents that disclose the environmental impact of a product, including its embodied carbon. They’re a useful tool for comparing similar materials. - Assess Local vs Imported Options:
Transport emissions can add significantly to embodied carbon. Locally sourced materials often come with a lower carbon footprint – and support the local economy. - Prioritise Recycled or Reclaimed Materials:
Recycled aggregates, reclaimed bricks, or repurposed timber drastically reduce emissions by avoiding new extraction and processing. - Consider Durability and Lifespan:
A longer-lasting product means fewer replacements and repairs – and less carbon in the long run. - Avoid Over-specification:
Using more material than necessary adds cost and carbon. Working closely with landscape designers and suppliers can help strike the right balance between performance and sustainability.
Greener Choices in Landscape Procurement
At Flora-tec, our approach to landscape construction reflects this commitment. We focus on sourcing sustainably, minimising waste, and designing for longevity. Where possible, we integrate low-carbon alternatives, and we regularly review our supply chain for environmental performance.
We also offer clients guidance on selecting materials that align with their sustainability targets – whether it’s opting for permeable paving to manage surface water sustainably or choosing recycled content for boundary treatments.
Making Every Project Count
Reducing embodied carbon isn’t about grand gestures – it’s about making informed choices, every step of the way. From tree planting to hardscape specification, each decision shapes the overall environmental footprint.
As expectations rise for greener spaces, organisations that take the lead on carbon-conscious procurement will not only meet regulatory and ESG requirements – they’ll also play a genuine role in protecting the planet.
