Life Cycle Assessment (LCA) is a comprehensive environmental evaluation tool that measures the whole environmental impact of a product from its birth through to its end of life (cradle to grave). The study starts measuring the carbon output from the production of raw materials (cradle) up to its ultimate disposal (grave).
When conducting an LCA study, internally accepted methodologies and standards must be followed e.g. ISO 14040, ISO 14044 and other relevant international standards such as the Confederation of European Paper Industries (CEPI) 10 toe of carbon offset and footprint for board and paper products.
What is the result of Double A’s LCA study? How was it derived?
Double A claims a reduction of 12.5 kg CO2 per ream from the result of the LCA (Life Cycle Assessment) study it carried out. This result was verified and confirmed by three independent institutions namely Asian Institute of Technology (AIT), Chulalongkorn University and KCL-Finland. Furthermore, Double A’s LCA followed the universally accepted methodologies as per ISO 14040 and Confederation of European Paper Industries (CEPI) Ten Toes for carbon footprint and carbon offset of paper products.
The purpose of the LCA is to measure the environmental impact of Double A paper from cradle – production of raw materials to grave – or the final products’ ultimate disposal. To make the process faster Double A decided to limit the study to “cradle to mills gate” or until the final product leaves the mill.
Double A LCA considered the 2 key parts of paper making
1) The Paper from KHAN-NA which has a carbon absorption/offset of 7,500 kg of CO2 (based on the 300 million trees)
2) The pulp and paper making process at mill which releases 2,500 kg of CO2 (using biomass energy combined with power generated from production energy sources).
Given the above figures, here’s how the 12.5 kg was derived:
7,500 kg CO2 offset – 2, 500 kg CO2 footprint = 5,000 kg CO2 offset
5,000 kg CO2 offset = 1,000 kg of paper
5 kg CO2 offset = 1 kg of paper
5 kg CO2 offset X 2.5* kg = 12.5 kg CO2 reduction per ream of paper
What is the LCA study scope of Double A ?
The scope of Double A’s LCA is from “cradle to mill gate”.
Why is Double A’s LCA limited only to from cradle to mill gate?
With the reason that all mills ship globally and recycle rates vary; these are factors outside our control.
How credible is the result for Double A’s trade and consumer?
The results of Double A’s Life Cycle Assessment (LCA) was verified and confirmed by three independent institutions namely Asian Institute of Technology (AIT), Chulalongkorn University and KCL-Finland.
