🌍 Less Emission. Same Ambition

Building responsibly—for today, tomorrow, and generations to come.

At K&W Construction, we believe that every company must do its part to protect the planet. Climate change is no longer a distant threat—it’s a visible reality. Scientists have warned for decades that a global temperature rise of 1.5°C marks a critical tipping point. At current pace, we may reach that threshold before 2030. The time to act is now.

🔋 Rethinking Construction

In our industry, sustainability means rethinking how we build:

  • Using and reusing materials with a lower COâ‚‚ footprint
  • Designing buildings to be energy-efficient and self-sufficient
  • Installing solar panels on every new project

The wars in Ukraine and Iran have shown how dependence on oil and gas creates geopolitical vulnerabilities. Fossil fuels are not just an environmental issue—they’re a strategic risk. That’s why we’re accelerating our transition away from them.

đźš— Greener Mobility

 We’ve fully electrified our passenger car fleet:

  • As of end 2025, we operate 15 electric vehicles (EVs) and 3 hybrids
  • No non-electrified cars remain in our fleet

 To offset our electricity use, we’ve installed an 80kW solar PV system at our office and depot, producing around 80,000 kWh annually—more than we consume, including EV charging. Starting in 2024, we share surplus energy with our construction sites.

🏡 Zero Energy Living

K&W is a pioneer in sustainable housing.

  •  We’ve built and sold 64 Zero Energy Houses
  • We are busy building 14 Zero Energy Houses in Wetteren
  • In 2027, we begin construction of our first Zero Energy Apartment block (www.heris.be)

Our concept combines proven technologies to deliver:

  • Cost-efficient, high-quality homes
  • Lower running costs
  • Superior comfort
  • Up to 50% reduction in COâ‚‚ emissions compared to traditional brick and stone construction
  • 3–6 months shorter build time

We aim to offer this system to project developers soon. Learn more at www.zeroenergyhouse.be.

đźš› Cleaner Transport

 To reduce emissions from our trucks and vans:

  • We use HVO-100 biodiesel, which cuts COâ‚‚ emissions by up to 90%
  • Currently using almost 50.000 liters annually, saving over 100 tons of COâ‚‚
  • We still rely on 20,000 liters of diesel for our vans, but plan to phase it out as HVO becomes more widely available
  • Read more about HVO-100

⚡ Greener Construction Sites

Since 2022, we’ve replaced diesel generators with battery packs from Locquet. Benefits include:

  • Lower noise and odor
  • Reduced maintenance
  • No fuel theft risk

Where grid power is insufficient, we now use HVO-powered generators (starting mid-2024).

📉 Our Progress & Goals

We have measured our scope 1 & 2 carbon footprint:

  • 2022: 358 tons COâ‚‚
  • 2023: 265 tons CO₂ 
  • 2024: 228 tons CO₂ 
  • 2025:  158 tons COâ‚‚ – that’s a 58% reduction since 2022!

Our total energy use has remained quite stabile with a slight increase from 851MWh per year in 2022 to 887MWh per year in 2025. This means that we have gone from 441kg CO2 per used MWh to 178kg CO2 per MWh which is a 60% decrease.

Our goal:

  • Phase out fossil fuels entirely
  • Replace with electricity and HVO
  • Achieve an 80% reduction in emissions compared to 2022
