The Environmental Impact of Building Materials

Why Material Choice Matters in Green Construction

The Construction Industry’s Role in Global Emissions

The built environment accounts for nearly 40 per cent of global carbon emissions, and choosing materials is one of the most impactful decisions in sustainable construction. If not managed responsibly, every stage of a building’s life cycle, from material extraction and processing to construction, maintenance, and demolition, contributes to environmental degradation.

Many widely used construction materials, such as concrete, steel, plastics, and synthetic cladding, require high energy inputs, emit significant CO₂, and contribute to long-term waste accumulation. With the 2025 World Environment Day theme focusing on ending plastic pollution, now is the time to prioritise natural, non-toxic, and locally sourced materials that support circular economy principles.

The High Environmental Cost of Conventional Building Materials

The impact of different building materials varies significantly, with some contributing far more emissions and waste than others:

• Concrete: Produces up to 8 per cent of global CO₂ emissions, requiring intensive heat and energy for production.
• Steel: One of the most energy-intensive materials, steel manufacturing contributes heavily to industrial air pollution.
• Plastic-Based Cladding & Composite Materials: While often marketed as durable, these materials contain synthetic resins and petrochemicals that release toxins, degrade in extreme weather, and contribute to microplastic pollution over time.
