Cement(ing) facts

The following is just to show how many different players are involved in the climate change issue:

• Concrete is the second most used product on the planet, after water
• Half of it is produced in China
• A business that produces more than 5% of mankind's carbon dioxide emissions
• Cement plants and factories across the world are projected to churn out almost 5bn tonnes of carbon dioxide annually by 2050 - 20 times as much as the government has pledged the entire UK will produce by that time
• The expected rapid growth in cement production is at severe odds with calls to cut carbon emissions to tackle global warming
• Already, some cement companies have taken steps to reduce their environmental impact. Some burn waste products alongside coal, while others have reworked their recipes and tried to make their plants more energy-efficient, with modest success
