Description
Direct emissions from the aviation industry accounts for 2% of global emissions. If global aviation was a country it would be in the top 10 emitters. The International Civil Aviation Organization (ICAO) forecasts that emissions could grow by a further 300-700% by 2050. In 2010 global cement manufacture released 3270 million metric tonnes of CO2 into our atmosphere. In 2020 that amount is estimated to be 4370 million metric tonnes of CO2. This will account for around 8% of global CO2. Replacing Portland cement with 70% GGBS in concrete reduces the carbon footprint associated with the cement content in concrete. Its use can reduce the embodied carbon footprint by 65% and play a major role in reducing global CO2. Specification and design documents for pavement quality concrete in airfield limit the use of GGBS to a maximum level of 35%. EN 206 exposure class for freeze thaw limits GGBS to a 50%. Increasing GGBS content to 50% or more could enhance sustainability, by meeting necessary requirement.
