Continued global growth increases the demand for construction materials. According to the World Wildlife Fund, the consequence of this growth is the projected global production of cement in 2030 will grow to a level roughly five times higher than that of 1990, or close to 5 billion tonnes worldwide. In turn, this growth impacts the overall level of greenhouse gas (GHG) emissions since the production of each tonne of cement produced results in emissions of roughly 0.648 tonnes of CO2 by ACMP members in 2013 (see Error! Reference source not found.). The key drivers ensuring a continual downward trend in CO2/tonne cement relate to the extent of alternate materials used and the implementation of energy efficiency measures at member operations. Future effort will be directed to the use of alternate fuels to substitute conventional fuels.

Figure 4: Total Carbon Emissions1
Figure 4 indicates total CO2 emissions for clinker and cementitious material produced. The production output of members has increased whilst the ratio of tonne CO2 produced per tonne cementitious material and per tonne clinker has reduced over the reporting period.
Indirect CO2 emissions from electricity (Table 2) used in cement production fluctuated, but shows decline in tonnes CO2 per tonne of cement toward the last reporting year.

To ensure sound sustainable development practice amongst our members, the ACMP has embraced the following climate change policy to inform their members response to climate change

ACMP CLIMATE CHANGE POLICY
All members of the ACMP recognize that climate change poses a real global threat to sustainable development that requires a global response. An effective global solution requires action from all countries that must be aligned with agreed global and national objectives. As a result all ACMP members aim to pro-actively adopt and/or develop mitigation and adaptation strategies to manage greenhouse gas emissions while incorporating national development goals.
ACMP members will achieve this objective by:
- Reporting and monitoring of CO2 emissions from the local cement manufacturing sector using globally accepted reporting protocols;
- Establishing business and operational plans to manage CO2 emitted;
- Establishing sector specific benchmarks for operational efficiency;
- Ongoing review of strategies, best practices and continuous improvement.
