We recommend that CARB add a Low Carbon Concrete Standard in the
2021 Scoping Plan. As operating emissions from buildings drops due
to efficiency and clean energy, the embedded carbon will be
increasingly important. We need to significantly reduce the
embedded carbon in building materials. We believe it is technically
and economically feasible to significantly reduce the emissions
from concrete by creating a declining emissions standard as
outlined in the attached document. Currently, only the cement
industry is regulated via the cap and trade program. The concrete
industry has many ways to innovate and concrete standard would
stimulate innovation.

The concrete industry can reduce emissions in part by reducing the
amount of portland cement needed. The portland cement industry has
various ways of reducing their emissions but ultimately the
industry needs to capture the CO2 emissions. We believe our
proposal will accelerate the timeframe to capture CO2. As outlined
in the staff report, California needs a multi-sector, vibrant CO2
capture, reuse and sequestration system in place before the end of
the decade. The cement industry can play a major role in
establishing such a system.
