BANPU CLIMATE CHANGE REPORT 2023

CLIMATE-RELATED TARGET PERFORMANCE GHG emission reduction targets We have set 5-year target (2021-2025) which aligned with our strategy. Meanwhile, we have developed long-term targets and their roadmap to achieve targets. We plan to announce the new long-term targets by 2024. Mining Business The emissions increased by 4% compared to the business-as-usual (BAU) due tohigher fuel consumption in open-pit mine. However, we have reduced GHG around 500 ktCO2e in underground mine.

This reduction was the result of the Company’s proactive approach in seeking opportunities to increase the proportion of total electricity generation from renewable energy and developing of initiatives on energy efficiency in our thermal power.
