Our Strategy 2020 Commitments
- Contribute to the delivery of a low carbon built environment
Carbon emissions from the built environment arise from two main sources; ‘operational’ from using buildings and infrastructure and those ‘embodied’ in the manufacture of construction materials.
Operational carbon from buildings is significantly greater than the embodied carbon in their construction materials. Concrete construction can make a significant contribution to reducing operational carbon through its unique combination of properties, in particular thermal mass. The Concrete Centre continues to provide best practice advice on low carbon design supported by regular events to share knowledge from exemplar projects.
The concrete industry is fully committed to reducing the embodied carbon within concrete, and reports on carbon intensity - kg of CO2 per tonne of concrete produced and energy intensity in kWh/tonne. This data includes the emissions and energy use from the supply of constituent materials.
Data is reported based on two average proportions of materials; the ‘Rolling mix’ based on an average of materials used per tonne of concrete for the reporting year and the ‘Standardised mix’ based on the materials proportions in 2008 when the strategy was introduced so that progress can be clearly assessed.
The 2020 target is a 30% reduction based on a 1990 baseline.
- Develop a Low Carbon Freight Initiative to support improvement in transport performance through the concrete supply chain to construction sites
Concrete is a UK manufactured product that is locally sourced, helping to reduce the CO2 associated with transport of materials to a construction project. Our current indicator is based on the CO2 emissions related to delivery transport.
Efforts are underway to address the wider social and environmental impacts of transport through improved scheduling, vehicle quality and driver training. There are also examples of manufacturers investing in more efficient fleet and sector initiatives to encourage and enable a greater use of rail freight.
MPA and the Rail Freight Group have published a series of commitments in their document A Commitment to the Future. Available at www.mineralproducts.org
The Mineral Products Association (MPA) is the trade association for the aggregates, asphalt, cement, concrete, dimension stone, lime, mortar and silica sand industries, and as such the commitment applies to concrete and constituent materials sectors that are part of the MPA.
