because that was the first year that most sources were
required to, and started reporting, emissions to the USEPA
resulting in reliable and comparable data.
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.
