In 2024, total of 12 products/process have been assessed with Eco-design Criteria in accordance with ISO 14062 standards such as Bio Compound and Post-Consumer Recycled (PCR). GC has plan to extend the scope of eco-design covering entire our future business.

Life Cycle Assessment (LCA)

GC has implemented the Life Cycle Assessment (LCA) in accordance with ISO 14040 and ISO 14044 standards. The assessment methods are categorized into three approaches:

  1. Full Life Cycle Assessment (Full LCA): This comprehensive method involves four key stages including Goal and Scope Definition, Inventory Analysis, Impact Assessment, and Life Cycle Interpretation.
  2. Simplified or Screening Life Cycle Assessment (Simplified LCA/Screening LCA): This method uses basic data and focuses on key environmental impact indicators, such as greenhouse gas emissions, allowing for quicker assessments and lower resource requirements.
  3. Alternative Environmental Impact Assessment Methods: This includes Material Flow Accounting (MFA) to analyze the flow of materials related to the product.
Life Cycle Assessment: LCA 2021 2022 2023 2024
Full LCA (%) 1 4 4 4
Simplified LCA/Screening LCA (%) 54 54 63 63
Material flow accounting (%) 45 42 33 33

GC’s products received environmental certifications, including Carbon Footprint of Product (CFP), Carbon Footprint Reduction (CFR), and Carbon Footprint of Circular Economy Product (CE-CFP) from the Thailand Greenhouse Gas Management Organization (TGO). The company also assesses direct and indirect water consumption and water efficiency in production processes, or water footprint, according to ISO 14046 while performing the Life Cycle Assessment according to ISO 14040 and ISO 14044.
