Case Studies: Real-world Examples of Companies Successfully Implementing ESG Practices

This chapter examines four leading frameworks widely used in environmental, social, and governance (ESG) research and corporate practice – Morgan Stanley Capital International (MSCI) ESG ratings, the Sustainability Accounting Standards Board (SASB) materiality map, the Global Reporting Initiative (GRI) standards, and United Nations Sustainable Development Goals (SDGs) mapping. Together, these tools provide structured approaches for assessing sustainability, enabling meaningful case studies, cross-sector comparisons, and alignment with global benchmarks. MSCI offers sector-relative ESG ratings that support peer benchmarking, while SASB highlights financially material, industry-specific issues. GRI standards focus on comprehensive disclosures and global comparability, and SDG mapping connects corporate strategies to broader societal and developmental goals. The analysis extends across seven sectors – energy, financial services, technology and information and communication technology (ICT), manufacturing and industrial goods, consumer goods, health care and pharmaceuticals, and transportation and logistics – each with distinct ESG priorities and challenges. Findings indicate that while technology and consumer goods sectors lead in standardised reporting and global alignment, resource-intensive sectors such as energy, logistics, and manufacturing face persistent gaps in assurance, labour rights, and environmental disclosures. Case evaluations reveal how firms are gradually improving practices through emission reduction targets, digital responsibility, product safety, and diversity and inclusion initiatives. Designed for both academics and practitioners, the chapter highlights the importance of materiality, comparability, and strategic alignment with international frameworks in ESG research. Various reporting standards and practices in various sectors have given insights wherein the organisations can enhance sustainability performance, and in the long run creating value and also contributing to the overall global sustainable goals.
