"Alibaba Group released the 2024 Environmental, Social, and Governance (ESG) report, detailing the progress made in various ESG areas over the past year. The report shows that Alibaba has steadily advanced its carbon reduction efforts, with the group'\''s net carbon emissions and carbon intensity of the value chain continuing to decrease. The group also continues to leverage digital technologies and platform capabilities to support accessible development, healthcare, aging-friendly services, and small and micro enterprises. Alibaba Group'\''s CEO, Wu Yongming, stated in the report: '\''The core of ESG is about becoming a better company. Over the past 25 years, the actions related to ESG have formed the foundation of Alibaba, which is just as important as the commercial value we create. While the group is focused on the dual business strategies of '\''user-first'\'' and '\''AI-driven,'\'' we also remain committed to ESG as one of Alibaba'\''s cornerstone strategies. Alibaba has made solid progress in reducing carbon emissions.'\''",
"The core of ESG is about becoming a better company. This year marks the 25th anniversary of Alibaba. Over the past 25 years, Alibaba has adhered to its mission of '\''making it easy to do business everywhere,'\'' supporting the prosperity of domestic e-commerce; maintaining an open ecosystem, with the Magic搭 community opening over 3,800 open-source models; assisting in rural revitalization, having sent 29 rural special envoys to 27 counties; promoting platform carbon reduction, pioneering a Scope 3+ carbon reduction plan; and engaging in employee welfare, with the '\''Everyone 3 Hours'\'' initiative making small but meaningful changes... These actions form the foundation of Alibaba, which is just as important as creating commercial value. I hope that every Alibaba employee will learn to make difficult but correct choices, maintaining foresight, goodwill, and pragmatism. A better Alibaba is worth our collective efforts. Alibaba'\''s mission, unchanged for over 20 years, is to make it easy to do business in the world. Today, this mission takes on new significance in this era."
