This chapter delivers a comprehensive overview of the global ESG performance by drawing on extensive ESG datasets of those from 2000 to 2020. It analyses the trends and variations in ESG scores across sectors, both financial and non-financial firms as well as across global regions, including Asia-Pacific, North America, South America, and Africa. The chapter stresses on a few issues: how firms worldwide have adopted energy-efficient technologies, how firms set emission targets that aligned with international accords such as the Paris Agreement, and how firms have increasingly disclosed climate-related risks and opportunities by using frameworks like the Task Force on Climate-related Financial Disclosures (TCFD). The chapter also discusses the evolution of sustainability frameworks and their core objectives in promoting transparency and accountability. In particular, the chapter explores the widely adopted ESG reporting standards of distinctive firms which applied specific frameworks that were traced to the Global Reporting Initiative (GRI), the Sustainability Accounting Standards Board (SASB), and the TCFD. The chapter elaborates on the importance of these frameworks in enhancing the consistency and comparability of ESG disclosures. The chapter concludes by providing valuable insights into the dynamic landscape of corporate ESG practices and the growing global emphasis on sustainable development.
