Climate change is an issue that we must all be concerned with. Those of us with greater influence must have greater concern. If an individual in their normal life reduced their emissions by 50% they might save 8 tonnes of CO2 annually (this would require halving their journeys, their heating, their holidays, their food consumption, etc). If professionals working in the construction industry reduce the emissions of their projects during construction by 50% they can save up to 4,000,000 tonnes of CO2 annually. During the construction peak, if half the cement used was green cement such as Ecocem over 2,000,000 tonnes of CO2 alone would have been saved. The beauty of this is there are no sacrifices required—no cost implications—no change in lifestyle habits—no structural issues (in fact it enhances the structural performance—see technical section). Changing one line in your specification1 will make lasting changes for the world we live in. These changes will benefit us forever. Please click here to download a specification for the inclusion of GGBS in your concrete.
In the next few sections you will learn of the massive savings in CO2, SO2, NOX and CO as well as in fine particulate that will be made by using Ecocem. You should also understand that Ecocem is made from a recycled material. Additionally, the life cycle footprint of structures made with Ecocem is significantly reduced because structures made with Ecocem can last over twice as long as structures made with traditional cement. You can also find out more about the health and economic benefits of using Ecocem. For any questions please click here and you can email them on, or see the FAQ section under Tools and Resources.
1. In your specification on concrete and under the section referring to cement all you need to include is a sentence along the following lines; “Ordinary Portland Cement (OPC) to be replaced with 50% Ground Granulated Blastfurnace Slag (GGBS) Cement unless otherwise stated.”
Despite the developed world being the major contributor to global warming, the main effects are currently most visible in the developing world. The situation in Darfur, according to the UN, the first violent conflict directly related to climate change, has left 300,000 dead and over 2.5 million refugees.
We invite you to try our calculator and find out about the savings you can make on your next project—even if you are only ever going to build one house you can save over 10 tonnes of CO2 on that project (the equivalent of leaving your car at home for over 2 years).
