On October 4, the world marked the annual United Nations World Habitat Day. The theme was 'Accelerating urban action for a carbon-free world'. This was in recognition that cities are responsible for 70 per cent of global carbon dioxide emissions, with transport, buildings, energy, and waste management accounting for the bulk of urban greenhouse gas emissions.
According to the World Bank, a global population of 4.2 billion people live in urban environments and this will increase by 2.5 billion people in the next three decades. This rapid growth in urban settlements is one of the key drivers of cement consumption.
