The report anticipates that over the period 2010-2018, the Green Concrete market is projected to increase at a compounded annual growth rate of 21.3%. "Green concrete is an eco-friendly concrete, characterised by its low environmental impact in terms of energy consumption and emission of carbon dioxide (CO2) and waste water in its manufacturing process." These include energy-saving lighting fixtures, recycled content-based concrete and water-efficient plumbing fittings and fixtures. Major factors driving demand for green building products include higher availability of such products, increasing environmental concerns and stringent building code and regulatory standards. Of these products, recycled concrete represents the largest segment in value terms, while other products continue to make a small contribution in terms of value sales."
