Our school cooperated with the government to implement the "Government Agency and School Energy Conservation Action Plan" (plan period: 2016 ~ 2019) in phases. The plan took 2015 as the base period to increase the overall power consumption efficiency by 4% in 2019. As of 2019, the annual total electricity consumption had decreased by approximately 9.12% compared with 2015, and the CO2 reduction was 1,520,670kg [2,853,095 degrees (the total annual electricity consumption reduction as of 2019 based on 2015) * 0.533 (electricity emission factor in 2018: kg CO2e/degree)].
