CLOCS Standards Update

CLOCS has published version 4 of the CLOCS Standard which becomes effective from 1 August 2022. The CLOCS Standard is a set of requirements for all stakeholders to help ensure safer, leaner and greener construction logistics, which demands collaboration between the construction and fleet sectors to address shared issues and draws together best practice from a number of standards, policies and codes of practice to provide one industry standard that can be implemented by all.

The two main changes around collisions and emissions data collection and reporting and fleet accreditation requirements.

Full details of the changes, as well as a copy of version 4 of the CLOCS Standard can be viewed and downloaded at  A PDF summary of the changes can be downloaded below.
