Product approval & certification

BBA certification is recognised throughout the construction industry as a symbol of quality and reassurance. It's the vital ingredient in the provision of assurance, quality and integrity to a plethora of stakeholders in the construction industry.

Reducing Carbon in Concrete Erosion Protection Structures

10

With global carbon emissions reaching an all-time high, there are calls from scientists and environmental activists for governments, corporations and companies to act to prevent the further acceleration of climate change.

The Current Situation

The concrete industry is a leading producer of carbon dioxide (CO2), generating up to 8% of worldwide man-made CO2 emissions[1]. One of the main contributors to carbon emissions in the process of cement production is due to the high temperatures required to heat alite to the point of forming clinker.[2]

As a result, both the concrete industry and its clients must find ways to reduce carbon production in both the manufacturing process and end-use.

In 2013, the UK Government published ‘Construction 2025’, detailing their vision for the construction industry. They have set a target of lowering greenhouse gas emissions in the built environment by 50%. The British Board of Agrément (BBA) has supported the innovative ideas that aim to achieve this target.

The mission of the BBA is to support and facilitate quality and innovation in the construction industry, providing a catalyst for the development and application of safe, technically excellent and innovative solutions for a better- built environment.
