Cement Manufacturing Overview
Four Steps to Produce Cement | Voluntary Code of Conduct
Environmental Performance Measures
Environmental Performance Measures
The Environmental Performance
Measures translate the Cement Manufacturing Sustainability
(CMS) Program Principles into action. A long-term
reduction target is identified for each key performance
measure and then progress toward that target is
measured against a baseline. Currently there are
four goals approved by the PCA members:
- Carbon Dioxide (CO2)—The
U.S. cement industry has adopted a year 2020 voluntary
target of reducing CO2
emissions by 10% (from a 1990 baseline)
per ton of cementitious product produced or
sold.
- Cement Kiln Dust (CKD)—The
U.S. cement industry has adopted a year 2020 voluntary
target of a 60% reduction (from a 1990
baseline) in the amount of CKD landfilled per
ton of clinker produced.
- Environmental Management Systems
(EMS)—The U.S. cement industry has adopted
a year 2006 voluntary target of at least 40% of U.S.
cement plants having implemented an auditable
and verifiable EMS with 75% of the U.S. plants implementing an EMS by the end of 2010, and with 90% by the end
of 2020.
- Energy Efficiency—The U.S. cement industry has adopted a year 2020 voluntary target of 20% improvement (from 1990 baseline) energy efficiency—as measured by total Btu-equivalent per unit of cementitious product.
With these ambitious goals, cement manufacturers will reduce their environmental impact and energy burden. As discussed later in this document, additional energy and environmental benefits will be realized by the use of concrete in the construction of buildings and pavements. Portland cement concrete is a durable product that can provide years of benefits.
Reporting Protocol
PCA has conducted an annual survey of members since 1970 to collect data and compare it against a baseline to measure performance toward reduction targets on energy use and labor practices. This tool has been modified to collect information on the targets identified above.
