Abstract
This report describes the potential use of benchmarking for evaluating Clean Development
Mechanism (CDM) projects in the cement industry. We discuss a methodology for comparing
proposed projects against a benchmark using a process-step approach. We find that cement
production is well suited to a process-step benchmark methodology for evaluating energy use
because it consists of a number of discreet steps for which energy use can be measured. There are
three primary process steps that can be evaluated with a benchmark: raw material preparation,
clinker production, and cement grinding. Benchmark values ...
