Introduction Transforming care Investing in our people Accelerating possibilities Protecting the environment Creating value responsibly Appendix Reducing our environmental impact In 2022, we made measurable progress in addressing climate change. Boston Scientific Teams across the company worked to keep us on course to meet our global commitments met a milestone when our targets for net-zero GHG emissions by 2050 were approved by the for net-zero emissions, carbon neutrality, renewable electricity and waste management. SBTi. This approval, which encompasses scopes 1, 2 and 31, was received less than a year after Progress against our environmental targets is also a key component of our environmental, we expanded our climate goals by committing to set science-based targets and joining the social and governance (ESG) scorecard that is part of our annual employee bonus program. United Nations Race to Zero and SBTi Business Ambition for 1.5°C campaigns. For additional information about our ESG scorecard, please see the company’s 2023 Proxy Statement. 2 Our path to net-zero One of the first medical device manufacturers to pledge Near-term targets (2019 base year): 3 to achieve carbon neutrality (scopes 1 & 2) by 2030 46.2% absolute reduction in scopes 1 & 2 Visit our Protecting the SBTi GHG emissions environment website to learn 3,4 3 76% renewable electricity , 40% renewable energy , received SBTi approval of net-zero emissions target 55% reduction in scope 3 GHG emissions more about our commitment per USD value added to science-based targets. 100% renewable electricity3,4 3 90% renewable energy (all sources) Net-zero emissions (scopes 1, 2 & 3) 3 Carbon neutrality (scopes 1 & 2) Long-term targets (2019 base year): SBTi 97% reduction in scopes 1 & 2 GHG emissions per USD value added (equivalent 1 Scope 1 emissions are direct emissions from owned to 90% absolute reduction) or controlled sources. Scope 2 emissions are indirect emissions from the generation of purchased energy. 97% reduction in scope 3 GHG emissions Scope 3 emissions are all indirect emissions (not per USD value added included in scope 2) that occur in the value chain of the reporting company, including both upstream and downstream emissions. 2 Trajectory to net-zero emissions defined by science- based targets to reach net-zero greenhouse gas emissions across the value chain by 2050 from a 2019 base year. 3 Inclusive of all manufacturing and key distribution sites only. 4 Purchased electricity matched with electricity from 2017 2022 2024 2027 2030 2050 renewable sources. 40 2022 Performance Report
