Looking around the world, GHG is an issue that enterprises must seriously face. In addition to voluntarily promoting the relevant energy conservation and carbon reduction measures, designing and producing energy conservation and environmental friendly green products, CMI has aggressively participated in the legislation of the competent authorities in cooperation with the Taiwan TFT-LCD Industry Association (TTLA). These included the drafting of the Greenhouse Gas Reduction Act, Energy Tax Statute, Renewable Energy Development Statute and Energy Management Act. Furthermore, CMI signed on to the Carbon Disclosure Project (CDP) and Supply Chain leadership Collaboration (SCLC) to disclose to the public the information concerning CMI’s analysis and responsive actions for climate change risk and opportunities, measures and performance in carbon reduction, GHG emissions, supply chain GMG management, and product lifecycle.
Since 2005, CMI has been performing GHG inventory every year and third party external verification according to the -1 International Standards. The inventory for 2010 has been scheduled in May 2011 for internal inventory and verification in July 2011 for third party verification.
GHG emissions are categorized into three scopes: (1) Scope 1—all direct GHG emissions; (2) Scope 2—indirect GHG emissions from consumption of purchased electricity, heat or steam; and (3) Scope 3—other indirect emissions. According to the GHG Protocol, GHG emissions covered in Scopes 1 and 2 must be inventoried qualitatively and quantitatively; and GHG emissions covered in Scope 3 only needs qualitative inventory.
In 2010, the GHG emissions of CMI were 3.625 million tons CO2-e. The scope of inventory covered plant sites in both Taiwan and China, with GHG emissions at 2.959 million tons CO2-e and 0.666 million tons CO2-e respectively. Most part of GHG emissions falls into Scope 2; i.e. purchased electricity and steam, which accounts for 85% of the emissions, or 3.094 million tons CO2-e.
To LCD factories, as much as 82% of GHG comes from purchased electricity and 16% from FCs, carbon emissions can be achieved by means of energy conservation and FCs reduction. From 2005 to 2010, although the total panel area increased by 430% due to capacity expansion, GHG emission increased by only about 65%. Also, the GHG emission intensity in 2010 was 0.0590 tons CO2-e/m2, significantly reducing by about 70% compared to that of 2005.
-FCs Reduction Commitment: In 2004, CMI participated in TTLA and signed the voluntary reduction MOU to express its commitment to equip all new plants built after 2003 with the local scrubber. Also, it will reduce FCs emission intensity to 0.0335 tons CO2-e/m2 in 2010.
-FCs Reduction Performance: By voluntarily investing in and installing high-efficiency combustion-type local scrubbers, the total amount of GHG emissions reduced during 2005-2010 was 10.04 million tons CO2-e. In 2010, the FCs emission intensity reduced to 0.0094 tons CO2-e/m2. When compared with 2005, the reduction is up to 87%, and even far better than the said committed FCs strength.
