The Climate Action Reserve is developing a U.S. Low-Carbon Cement Protocol that will provide guidance on how to quantify, monitor, report, and verify the climate benefits associated with the alternative use of supplementary cementitious materials (SCMs) to produce cement. Production of ordinary portland cement (OPC) accounts for approximately seven percent of all global carbon dioxide emissions with most of these emissions resulting from calcination to produce clinker, the primary intermediate component of OPC. With the opportunity to significantly reduce emissions by replacing clinker with byproduct or naturally derived SCMs, the U.S. Low-Carbon Cement Protocol will incentivize industrial-scale SCM availability to meet market demands and achieve emission reduction ambitions.
The Reserve seeks to engage stakeholders throughout the U.S. Low-Carbon Cement Protocol development process to identify and incorporate applicable laws, norms, and conditions applicable to the cement industry in the United States as well as specific improvements and changes to existing industrial manufacturing processes to ensure its successful implementation.
The U.S. Low-Carbon Cement Protocol is being developed through the Reserve’s multi-stakeholder workgroup process. The Reserve strives to create a well-balanced workgroup consisting of industry representatives, project developers, environmental NGOs, verification bodies, independent consultants, academia, and government bodies.
