IEA (2009), Cement Technology Roadmap: Carbon Emissions Reductions up to 2050, IEA, Paris https://www.iea.org/reports/cement-technology-roadmap-carbon-emissions-reductions-up-to-2050
The cement energy technology roadmap outlines a possible transition path for the industry to make continued contributions towards a halving of global CO2 emissions by 2050. As part of this contribution, this roadmap estimates that the cement industry could reduce its direct emissions 18% from current levels by 2050. This roadmap is a first step. It is only attainable with a supportive policy framework, and appropriate financial resources invested over the long term.
