reduction targets and an
analysis of performance In 2023, we established a new Net Zero
against those targets Scope 1 Ambition for 2050, in addition to
our existing Net Zero Scope 2 Target for
2050 – our Net Zero Ambition now covers
our Scope 1 and 2 emissions across all our
businesses.
We also have a Scope 1 GHG reduction
commitment for 2030 for our cement and
magnesia specialties business.
We have converted more than 90% of our
Type I/II cement customers in Texas to PLC
or Type 1L, which we estimate contributed
to the 10.8% year over year reduction in
Scope 1 GHG emissions in our heritage
cement business.
We saw an 8.26% reduction in intensity in
our Woodville Magnesia Specialties
operations due to kiln upgrades.
