ASE MAKES CDP’S CLIMATE A LIST FOR THE FIRST TIME

ASE is the sole company from Taiwan and the only outsourced semiconductor manufacturer on the Climate A List issued by CDP, a non-profit global disclosure organization that promotes low carbon outputs and the disclosing of climate mitigation plans and risks

Advanced Semiconductor Engineering, Inc. (ASE, TAIEX:2311, NYSE:ASX), the leading provider of semiconductor assembly and test services, today announced that it has made the CDP’s Climate A List for the first time. ASE is amongst 193 companies worldwide that was included in the list and also the only company from within the outsourced semiconductor manufacturing industry. Since 2009, ASE has been proactively responding to CDP’s questionnaires on carbon output disclosures and transparency in climate mitigation plans and risks. In 2015, ASE signed on as a signatory to CDP’s initiative 5.1. Climate Change and Energy Efficiency.

According to the newly released CDP report ‘Out of the Starting Block’, the CDP’s Climate A List comprises a strong set of companies who lead on climate change mitigation today and in the future. Approximately 2,000 companies worldwide were assessed in 2016 and these companies were ranked from A to F. Those ranked A, were included in the Climate A List.

In the past year, ASE has shown significant improvements in promoting low carbon output as well as in the management of its greenhouse gas and carbon emissions. In 2015, ASE purchased a total of 7,200 MWh of ‘accredited green electricity’ sourced from renewable energy under the ‘Green Power Pilot Program’ by the Bureau of Energy, Taiwan. This purchase has resulted in a reduction of CO2 emission of about 3,754 metric tons equivalent to 312,000 trees planted. To further promote a low carbon environment, ASE has committed to construct all new buildings according to international green building standards. Since 2012, ASE has invested over $270 million in green buildings. As of today, 16 buildings at ASE are certified by EEWH and LEED, with another 14 buildings undergoing certification requirements. ASE is also playing its part in educating and supporting public initiatives on carbon footprint reduction by creating the ASE30 Environmental Conservation Fund. The fund was established to commemorate the company’s 30th anniversary and to promote programs in support of environmental protection efforts in Taiwan. The company has committed to contributing NT$100 million (US$3 million) per year from the NT$3 billion (US$100 million) fund for the next 30 years.

‘We are deeply honored to receive this recognition from CDP, which is an organization identified by global investors to have the most credible and beneficial sustainability reporting framework. The inclusion of ASE on the Climate A List is a strong endorsement of ASE and the team’s efforts in reducing our carbon footprint while balancing business performance and increasing long term shareholder value,’ says Jason Chang, Chairman and CEO of the ASE Group. ‘As we continue to be an innovative player in advanced semiconductor technology that forms the backbone of today’s electronic products, we remain committed to take the lead in creating a sustainable future that will reduce harm to humans and the environment, and to protect mother nature.’
