Note: 2020 is the based line year for the carbon reduction target, and the reduction basis includes the GHG emissions in Scope 1 and Scope 2. |
In addition to continuously improving energy efficiency, we are also planning for the use of renewable energy. It is expected that by 2025, we will continue to replace energy-consuming equipment to save energy, and evaluate the introduction of energy storage facilities to stabilize electric power quality in our plants while curbing peak electricity consumption at the same time. We plan to use renewable energy and to complement it with solar photovoltaic facilities by 2030 to reduce greenhouse gas emissions caused by our operations in accordance with operational needs.
The 2021 annual GHG inventory is conducted following the ISO 14064-1:2018 standards. The boundary includes plants in Taiwan and all plants in Mainland China, to grasp the overall GHG emissions, and review and set carbon reduction targets. The total emissions of Scope 1 and 2 in 2021 were 946,861 tons of CO2e, a decrease of 2% compared to 2020. There is a decrease of 21% shown by the calculation of the intensity value per million revenue. The reduction in GHG emission intensity within the Unimicron is due to the increase in production efficiency within the plants and the revenue.

Shenzhen City in Mainland China, took the lead in launching carbon emissions trading in June 2013. For companies included in the key energy consumption statistics (monthly emissions> 10,000 tons of carbon emissions, Unimicron (Shenzhen)’s has an average of 15,000 tons/month in 10-12 years) must conduct compulsory carbon emissions trading (i.e., emission control units). Therefore, Unimicron (Shenzhen) begins to join the Shenzhen carbon trading mechanism in 2014. As of 2020, the cumulative carbon emissions were approximately 809,600 tons. Based on industrial value-added, retrospectively, the could get quota in 2020 was about 84,400 tons, and the total cumulative quota was about 964,200 tons from 2014 to 2019. After offset, there is still a balance of 154,600 tons, which is temporarily retained without trading. Since 2016, Unimicron (Shenzhen)’s annual carbon emissions have exceeded the carbon emission quotas, and the remaining carbon emission quotas in the future will be used to offset Unimicron (Shenzhen)’s annual carbon emissions. Due to the impact of the pandemic, the 2021 carbon trading mechanism would be opened in May 2022.
