Product Life Cycle Assessment (LifeCycleAssessment, or LCA), it is an environmental impact assessment method set by international ISO14040 standards, and it is an environmental impact assessment for a specific product from the life cycle of raw material procurement, processing, manufacturing, sales, use and disposal or recycling. It usually refers to the sum of the whole stages of the product (process) "from cradle to grave", which has a profound impact on the current quantitative assessment of environmental processes, the evaluation of process environmental effects, the optimization of product design and many other aspects.
We calculate product Carbon Footprint, generally used is the first, life cycle analysis is a bottom-up calculation method, is the product and its "from start to finish" process calculation method, the calculation process is more detailed and accurate.
enterprise utilization LCA Lifecycle in order to prepare the carbon footprint report, the whole production path of the evaluated products should be clearly sorted out and statistically counted, the energy used by suppliers to produce raw materials should be verified, the emissions in the transportation process should be calculated, the energy used in their own factories should be defined and calculated, and the emissions from packaging, sales and transportation and scrap treatment should be carried out.
The purpose of the impact assessment is to evaluate the environmental impact of the product life cycle based on the results of the inventory analysis phase. This process translates inventory data into specific impact types and indicator parameters, making it easier to understand the environmental impact of the product life cycle. In addition, this phase does not yet provide the necessary information for the Life Cycle Results Interpretation phase.
Source of data used in the main calculation phase of the carbon footprint report:
1. Raw material production stage: The main data source is the energy data of some products supplied by suppliers.
2. Raw material transportation stage: the main data source is the estimation of supplier transportation distance and CLCD-CHINA database.
3. Product production stage: report the main color production energy data.
4. Product transportation stage: estimation of customer transportation distance and CLCD-CHINA database.
5. Product use stage: CLCD-CHINA database and other estimates.
