Executive Summary
This case study evaluates the greenhouse gas (GHG) emissions of a leading garment manufacturing unit in Tiruppur, India, following the GHG Protocol and ISO14064 standards. The facility’s Scope 1 emissions, from direct fuel use and vehicles, totalled 245.81 metric tons of CO₂e, primarily from diesel in boilers and power generation. Scope 2 emissions, from purchased electricity, reached 360.42 metric tons of CO₂e after renewable energy offsets. Combined, Scope 1 and 2 emissions were 606.23 metric tons CO₂e, with an emissions intensity of 0.23 kg CO₂e per garment. The facility demonstrates a commitment to low-carbon strategies through renewable energy use. Recommendations include a 20% emissions intensity reduction by 2027, enhanced energy efficiency, and Scope 3 mapping. This positions the company as a potential climate leader in the apparel sector, with opportunities for broader industry impact through transparency and sustainable practices.
Recommendations
- Set Formal Reduction Targets:
Aim for a 20% reduction in emissions intensity per garment by 2027 through energy efficiency and low-impact technologies. - Expand Renewable Energy:
Increase on-site renewable energy generation and green procurement to further reduce Scope 2 emissions. - Initiate Scope 3 Mapping:
Quantify upstream and downstream emissions to enable comprehensive lifecycle impact assessment. - Adopt Advanced Technologies:
Integrate low-carbon manufacturing processes to enhance efficiency and reduce emissions. - Enhance Transparency:
Continue aligning with GHG Protocol standards and publicly report progress to build credibility and industry leadership.
Major Learnings for the Industry
Conclusion
The garment manufacturing unit has established a robust baseline for GHG management, with combined Scope 1 and 2 emissions of 606.23 metric tons CO₂e and an emissions intensity of 0.23 kg CO₂e per piece. Its partial adoption of renewable energy, offsetting 229,651 kg CO₂e, reflects a commitment to sustainability. The facility is well-positioned to lead the apparel sector in Tirupur by setting ambitious reduction targets and expanding low-carbon strategies. Initiating Scope 3 accounting will further strengthen its climate strategy, ensuring alignment with global sustainability benchmarks like Science-Based Targets.
