In 2017, Delta estimated its carbon reduction responsibility based on the simulation scenario of global warming within 2°C put forth by the International Energy Agency (IEA). Delta set an annual carbon intensity reduction target of 56.6% by 2025 with 2014 as the base year. It also passed a compliance review by the Science Based Targets initiative (SBTi) in December 2017 as the first company in Taiwan and the 87th in the world to pass the review. Delta further responded to the 1.5°C target in 2019.
Since the launch of the SBTs, Delta has achieved successive targets at each stage. In 2019, Delta's Scope 1 and Scope 2 carbon intensity (CI) at its main plants was 34.6 (metric tons of CO2e/million US dollars output value; market-based), a 29% decrease compared to the base year of 2014 while 16% compared to 2018. Reaching its SBTs for two consecutive years demonstrates Delta’s determination to fulfilling its SBT committments.
