Aggregate Industries obtains PAS 2080 verification
05 April 2019UK: Aggregate Industries, a subsidiary of LafargeHolcim, has obtained PAS 2080 verification, a new Carbon Management in Infrastructure specification. PAS 2080 is the world’s first specification for managing whole-life carbon in infrastructure. Developed by the Construction Leadership Council’s Green Construction Board with the British Standards Institute (BSI), it provides a framework and guidance for measuring and managing carbon across the whole value chain.
“We can help designers at Early Contractor Involvement (ECI) stage to design lower carbon solutions. Our management systems (ISO 14001 and 50001) ensure consistent and reliable data collection, allowing our Carbon Managers to report embodied CO2 to other members of the value chain. Baseline data made available to the value chain allows carbon targets to be set at design phase and for performance to be monitored against these targets during project delivery. This will result in infrastructure with lower embodied carbon,” said Paul McCaffrey, Sustainable Products Manager at Aggregate Industries.
US: Cemex USA’s Clinchfield Cement Plant in Georgia has been awarded the ISO 14001:2015 certification for its environmental management system (EMS). It is the first Cemex cement operation in the country to earn this certification. The EMS at the plant follows a continuous cycle of environmental policy: planning, support and operation, performance evaluation, then improvement.
The International Organization of Standardisation (ISO) developed ISO 14001:2015 as a standard of processes for organisations to use when setting up, improving or maintaining their environmental management systems to follow established environmental policies and requirements. The guidelines are designed to help organisations improve efficiency, reduce waste, improve overall environmental impact and manage environmental obligations.
The Clinchfield Cement Plant is also one of several Cemex sites to achieve certification from the Wildlife Habitat Council. The plant is also active in the Georgia Black Bear Project. Cemex is currently in the process of achieving ISO 14001:2015 Certification at its eight other active cement plants in the US.

UK: The Global Cement and Concrete Association (GCCA) has launched its first six sustainability guidelines. The six guidelines include a number of key performance indicators (KPI) against which full member companies must monitor and report on their sustainability performance across a number of key activities. The guidelines include monitoring and reporting CO2 emissions and other emissions from cement manufacturing, co-processing of fuels and materials, safety and water usage.
“Signing up to the guidelines emphasises the cement and concrete sector’s commitment to sustainable development including its critical work to reducing global CO2 emissions,” said GCCA Cement Director Claude Lorea.
To achieve the extended compliance, full GCCA members will have their data and targets verified and reported publicly. GCCA intends to communicate data publicly in a consolidated format. In November 2018 the GCCA published a Sustainability Charter which set out five key pillars, which it says encompasses the sustainability spectrum of the cement and concrete sector.
