Carbon Leadership Forum provides updated concrete PCR

The Carbon Leadership Forum has updated their PCR for concrete. From CLF:

In response to request by LCA practitioners preparing Concrete EPDs, the attached clarification to the CLF Concrete PCR has been issued.

This provides guidance on how to allocate truck (transit) energy that is used to mix concrete for plants in which the concrete is mixed in the truck, not in the plant.  This clarification is posted on the CLF website http://www.carbonleadershipforum.org/epds-and-pcrs.html
