climate change mitigation
according to the world meteorological organization, 2015 to 2020 is the hottest period in earth's recorded history. this indicates that global warming is spiraling out of control and immediate actions are urgent. as climate change has become one of important sustainable development issues, so usi pays attention to the international response measures to global warming, continuing our analysis and control works, and pursuing environmental and corporate sustainability.
carbon management
the total co2 emissions in 2020 were 190,974.17 tonnes (category 1 & category 2) with an increase of 13,804.85 metric tonnes from 2019, and emissions per million cny turnover were 4.02 metric tonnes, a decrease of 0.83 metric tonnes from 2019. since the introduction of the inspection of scope 3 of the taiwan-tt facility in 2018, the facilities in china also began theirs in 2019.
