Rapidly rising food prices have led to instability in many countries and have fuelled inflation in less developed economies where food spending is a greater proportion of overall consumer spending. A number of factors have contributed to this rapid rise in prices, but one important contributory factor is the move towards growing crops that can be used as bio-fuels in the developing world and this shift in production is having a knock-on effect in world food markets.

Cement may be quietly emerging as one of the biggest obstacles to lowering carbon emissions to reduce the extent of global warming. The cement industry rarely features in media analysis of the ‘worst polluters’, but in fact the industry is responsible, because of the high energy requirements of manufacture, for more than 5% of carbon dioxide emissions. A building boom globally has fuelled demand for the material. Concrete is the second most used product on the planet, after water, so what can be done to reduce the impact of the industry on the environment?
