GNR – GCCA in Numbers

The sector is fully committed to achieving significant sustainability progress. The GCCA gathers and publishes key data recording the industry’s sustainability commitments. The GNR (“Getting the Numbers Right” or “GCCA in NumbeRs”) is a key tool in how key sustainability progress is monitored and reported.

Latest data

The 2018 GNR data is available here. The headline findings are as follows:

  • The 2018 Cement Industry GNR data show a significant 19.2% reduction in CO2 per tonne of cementitious has been achieved since 1990
  • The proportion of alternative fuels used is now 9.5 times greater than in 1990
  • Energy efficiency has also been improved by 18%

Fossil fuels substitution – Biomass from waste

One example of the progress made to date is the use of biomass and alternative fuels, such as municipal and industrial wastes. These waste materials have been diverted from landfill and incineration and are co-processed during cement manufacturing. Co-processing offers higher environmental performance than landfill and incineration. It is a practical, cost-efficient and safe waste management option. Use of biomass and alternative fuels reduces consumption of fossil fuels and has seen an eight-fold increase between 1990 and 2017.

The benefits of fuels substitution are multiple

• Reducing CO2 emissions
• Reducing dependence on fossil fuels
• Material recycling
• Offering an alternative to landfill

About the GNR

Click here to access the latest 2018 data and the full GNR database (“Getting the Numbers Right” or “GCCA in Numbers”).

The GNR database is now managed by the GCCA, having transferred at the end of 2018 from the Cement Sustainability Initiative (an initiative run through the World Business Council for Sustainable Development). It is accessible here*. To access the CO₂ and Energy Accounting and Reporting Standard for the Cement Industry Excel Spreadsheet and Internet Manual, in English or Chinese use following links:


The GNR database is open for all interested parties to view data. The years for which data is available are: 1990, 2000, and 2005 to 2018. You can contact the GNR Project Management Committee if your company or organization is interested in finding out more about participating in the GNR system or about making data queries. GNR is a GCCA project but it is also contributed to by non-GCCA member companies. (Cembureau and FICEM are also key data and financial contributors.)    

Individual queries about specific issues are answered within strict confidentiality guidelines.

Charges may be levied on data requests to cover operational costs, especially with regard to complex data requests. The database complies with anti-trust laws and is managed by an independent third-party service provider. Individual participants may only see reports based on their individual company data or aggregated results. Confidential information on individual companies or plants is not disclosed, nor made accessible, and is protected by contractual and data security measures.
