This document discusses low carbon pathways for development in the construction sector in South Asia. It notes that rapid urbanization, population growth, and rising incomes are putting pressure on land, water, materials, and energy resources while increasing air and water pollution. The construction sector accounts for a major share of greenhouse gas emissions due to the energy-intensive nature of materials like cement, steel, and bricks. It argues for mainstreaming cleaner production processes and greener building materials like fly ash bricks to reduce environmental impacts. Policy support is needed to promote the use of alternative materials through procurement guidelines, incentives for green businesses, and clean technology standards.
