Key Findings
- 01Global process emissions from cement production in 2016 were 1.45 ± 0.20 Gt CO2.
- 02These emissions constitute about 4% of emissions from fossil fuels.
- 03Cumulative emissions from 1928 to 2016 were 39.3 ± 2.4 Gt CO2, with 66% occurring since 1990.
- 04Emissions in 2015 were 30% lower than those recently reported by the Global Carbon Project.
Application
Design takeaway
When evaluating the environmental impact of materials, always seek the most current and validated data, as significant revisions can alter the perceived sustainability of a product or process.
How to apply
When conducting an LCA for a product using cement, ensure the CO2 emission factors used are from recent, reputable sources that prioritize official data, rather than relying on older, potentially inflated figures.
Project actions
- 01When researching materials for your design project, always look for the most up-to-date environmental impact data.
- 02Consider how even small changes in data can affect the overall sustainability rating of your product or system.

Variables
Strengths & Limitations
Strengths
- +Prioritizes official and UNFCCC data for higher accuracy.
- +Provides updated estimates for key regions like China and India.
- +Offers a more realistic assessment of cement's contribution to global CO2.
Limitations
The study's findings are based on data up to 2016; current emissions might have changed due to new technologies or production shifts. Also, it only covers process emissions, not emissions from energy used in cement production.
Reliability & validity
The study enhances reliability by prioritizing official data, reducing reliance on potentially speculative estimates. Validity is improved by incorporating more comprehensive and up-to-date regional data, leading to a more accurate representation of actual emissions.
Think critically
How might the perceived 'sustainability' of concrete change if these emission figures were even lower, or significantly higher? What are the implications for policy and design decisions if data is constantly being refined?
Design Principles
"Data-driven sustainability assessment: Base environmental impact decisions on the most accurate and officially validated data available."
Understanding the true environmental impact of materials like cement is crucial for sustainable design and material selection. This insight provides more accurate data for life cycle assessments and informs strategies for reducing embodied carbon in construction, directly linking to green design principles and resource management.
What This Means for Your Design
This study found that cement production, a major source of CO2, actually produces 30% less CO2 than we thought before. This means cement might not be as bad for the environment as some older reports suggested.

According to Andrew (2018), global CO2 emissions from cement production in 2016 were 1.45 ± 0.20 Gt CO2, which is approximately 30% lower than previously reported estimates. This refined data, derived from prioritizing official sources and UNFCCC submissions, underscores the importance of utilizing the most current and validated environmental impact data when conducting Life Cycle Assessments (LCAs) for design projects. This more accurate understanding of cement's carbon footprint can inform more precise sustainable material selection and green design strategies.
