1 Facilities in most source categories subject to the USEPA’s
Greenhouse Gas Reporting Program (codified at 40 CFR Part 98),
including cement production, began reporting emissions in 2010.
Thus, we believe 2010 is a year with reliable and comparable data
across a wide range of facilities in the U.S. Our Scope 1 CO 2 e
emissions intensity associated with our cement operations in 2010
was 0.836. Notably, when we announced our 2030 emissions
reduction targets in 2019, as described above, we took into account
that we have been investing heavily over the past decade to reduce
our cement and magnesia emissions, which is reflected in our
favorable CO 2 e intensity performance relative to the U.S. cement
industry average. We also believe this has allowed us to achieve
significant environmental benefits from reduced emissions well
ahead of many other operators in the industry and will position us
not only to achieve our targets but to be in a good position to
evaluate additional actions in the future.
