The cement industry is changing. Consumption is growing, driven by demand in emerging countries. Almost everywhere, the concentration of players is increasing. Production remains fundamentally local, except for some fragmented markets such as sub-Saharan Africa.

profitability standards change, while the environmental and social imperatives must necessarily be taken into account.
Concrete shapes the built environment around us, from schools, hospitals and housing to roads, bridges, tunnels, runways, dams and sewerage systems. Few people realize that concrete is in fact the most used man-made material in the world, with three tons used annually for each man, woman and child. Twice as much concrete is used around the world than the total of all other building materials, including wood, steel, plastic and aluminium. Its superior properties on strength, durability, thermal mass and affordability make it the material of choice for most purposes. The production of concrete, notably its most important ingredient, cement, poses several sustainability issues that need to be managed: Cement production emits CO2 and other air emissions, and the quarrying of raw materials produces local impacts such as noise and
where water is scarce. Given the ubiquitous use of the material, it is also important to talk about the sustainability of the structures that are built with concrete. In particular, concrete is a key component to build durable and energy-efficient buildings..
Technology is a key pillar in the cement industry’s drive to reduce emissions levels and energy consumption. Research and development investments have enabled cement producers worldwide to install modern, energy-efficient technology in new, and to some extent, in existing, cement plants. New technologies have enabled increased use
to significant direct (e.g. from limestone decarbonisation) CO2 emissions reductions. Technology developments have also enabled significant indirect emissions reductions (e.g. from electricity use). For example, cement production by companies in the ‘Getting the Numbers Right’ (GNR) global cement database increased by 53% between 1990 and 2006, whereas absolute net CO2 emissions increased by only 35%. But existing technologies alone cannot reduce cement industry CO2 emissions indefinitely. A break-through technology is needed. For the cement industry, this means research, development, and piloting of carbon capture technologies in cement plants, improvements to energy efficiency, and the development & widespread implementation
80% of the future emissions from cement plants will take place in China and India. For the global cement industry to become more sustainable, especially with regard to achieving significant cuts in CO2 emissions, China in particular needs to be and has become an active contributor to climate protection efforts. Today China alone produces over half of the world’s cement, and this proportion is expected to rise further in the years to come, driven by continued economic development and cement demand as China provides housing and infrastructure for its burgeoning population. It is a delicate balancing act – cement is a key material for any country’s economic and social development, but the cement sector has an ecological footprint that it needs to manage over the long term.
