What is Decarbonisation?

Decarbonisation is the process of reducing carbon emissions. It means shifting away from fossil fuels (like coal, oil, and gas) to cleaner, renewable energy sources. This shift is crucial in mitigating climate change and ensuring a sustainable future.

Decarbonisation in the Construction Industry

Buildings and the construction sector are the largest emitter of greenhouse gases in the world, accounting for 37% of global emissions.[1] From the extraction of raw materials to the construction process itself, and even the operational phase of buildings, there are numerous opportunities for decarbonisation.

Key areas where the construction industry can reduce its carbon footprint include:

• Material Selection: Choosing low-carbon materials like timber, recycled steel, and sustainable concrete, rather than traditional steel or reinforced concrete, which require much more energy to produce.

• Efficient Design: Designing buildings that optimise energy use and minimise waste. Designing well-insulated, energy efficient buildings require less energy to run.

• Renewable Energy: Incorporating solar panels, wind turbines, or geothermal energy system, that allow the building to produce its own renewable energy supply with less input from the grid.

• Sustainable Construction Practices: Adopting methods like off-site manufacturing to reduce waste and energy consumption.

The Role of Environmental Accreditations

Environmental accreditations, such as the Green Accord, are a great way to evaluate your company’s decarbonisation journey. By adhering to these standards, businesses can:

• Reduce carbon emissions: By setting specific targets for energy efficiency, water use, material selection and vehicle usage.
• Promote sustainable practices: Encouraging the use of renewable energy sources and low-carbon materials.
• Improve building performance: Leading to lower operational costs and a healthier indoor environment.
• Enhance project reputation: Attract environmentally conscious clients and investors.

By embracing decarbonisation, the construction industry can play a vital role in building a sustainable future.
