Carbon Footprint

1 tonne of ACLA® has permanently removed 750kg CO₂e from the atmosphere. This is a cradle to gate (A1-A3) carbon footprint value, meaning it has taken into account the carbon emissions and benefits associated with raw materials and the production of ACLA®.
‍
ACLA® is a carbon-negative aggregate which acts as a permanent carbon storage solution for the decarbonisation of asphalt.

ACLA® utilises the carbon removal technology of sequestration to permanently remove carbon dioxide from the atmosphere.

Sequestration is the process where a material captures and stores carbon dioxide to prevent its release into the atmosphere.
‍
Asphalt roads account for over 95% of all UK roads, and 25 million tonnes of asphalt are produced annually (Asphalt Industry Alliance, 2021). Tackling the emissions of asphalt is, therefore, vital for the UK road network to decarbonise in line with the country’s legally binding target of achieving net zero by 2050.

Typically asphalt generates emissions of 30-70kg CO₂e/tonne.

To achieve net zero, 5-7% of ACLA® by weight of the total asphalt mix is likely required depending on the embodied carbon of the mix designs.
