Sustainability is no longer just a buzzword – it’s becoming a way of life. Across the globe, there’s been a conscious push toward greener choices and long-term practices that protect our planet.
We all want a greener future, but what does that look like here in the UK? In this post, we’ll break down what “Net Zero” really means, the steps being taken to get us there by 2050, and even how something as everyday as your composite front door can help make a difference.

UK Net Zero Targets 2050: What They Mean and Why They Matter
The UK has set a legally binding goal to reach Net Zero emissions by 2050, meaning the country must balance the greenhouse gases it produces with those it removes from the atmosphere. In other words, every tonne of carbon we emit must be offset by actions like planting trees, improving energy efficiency, or using new technologies like carbon capture.
To stay on track, the government has also committed to ambitious interim targets: cutting emissions by 68% by 2030 and 81% by 2035, compared to the levels in 1990. These milestones form part of the UK’s wider climate strategy, driving changes in how we power our homes, travel, and even the materials we choose for everyday products.
For households and businesses, this shift isn’t just about policy; it’s about taking steps, big and small, toward more sustainable living. From renewable energy to smarter building materials, every choice contributes to the bigger picture of a greener future.
Energy-Efficient Materials in Fenestration: How Front Doors Reduce Heat Loss
When people think about cutting emissions, renewable energy and electric cars often spring to mind, but our homes are just as important. Around 20% of the UK’s carbon emissions come from heating buildings, and much of that heat is wasted through poor insulation and outdated materials.
Modern composite doors are built with efficiency in mind. Multi-layered construction, insulated foam cores, and tightly sealed frames help prevent heat loss, keeping homes warmer without turning up the thermostat. The result is lower energy costs and less demand on fossil fuels, all in support of the UK’s Net Zero goals.
Endurance however, go the extra step. Our composite doors are built with a 48mm solid timber core made from 17 cross-laminated laminates. Stronger and more stable than foam-filled alternatives, the core resists warping and bowing while a built-in moisture barrier protects against the elements. The result is a door that delivers lasting strength, security, and performance.

Composite’s Role in Retrofitting
Retrofitting existing homes is one of the biggest challenges on the road to Net Zero. Millions of UK properties still rely on older doors that leak heat and push up energy bills. Replacing them with composite doors offers a practical, cost-effective solution – improving insulation, strengthening security, and instantly raising efficiency standards without the need for major structural changes.
By upgrading your front door with a modern Endurance composite, homeowners can enjoy greater comfort and lower bills, while the UK makes vital progress towards its 2050 targets.
Endurance Eco Alignment: Our Green Promise to Net Zero
At Endurance Doors, sustainability isn’t just a box to tick – it’s woven into everything we do. We’re proud to partner with Carbon Neutral Britain™ to offset emissions and maintain a carbon-neutral footprint, as well as work closely with suppliers and customers to lower environmental impact.
Our Kerto core composite doors aren’t just durable; they actively help reduce carbon in the atmosphere. These solid timber cores act as carbon sinks, storing roughly 1 tonne of CO₂ per cubic metre, while the entire core production from forest to mill remains carbon negative.
Transparency and responsible sourcing are central to our ethos. We only use 100% traceable wood from certified northern forests, replacing every felled tree with four new seedlings. Plus, we now ensure 0% of production waste goes to landfill thanks to our comprehensive recycling programme.
We’re not stopping there. Our “Green Promise” reflects a conscious commitment, from materials and production right through packaging. It’s about constant innovation and embedding sustainability into every door we create.
