ESG & Sustainability Ratings — Mining

ESG and sustainability ratings have become a principal tool by which institutional investors, lenders and index providers assess the non-financial risk profile of mining companies. The major raters evaluate climate strategy, tailings management, water stewardship, community relations, health and safety performance, and governance — criteria that are particularly material in extractive industries. This directory lists the primary rating agencies whose scores are most widely used in mining-sector investment decisions, along with links to each organisation's methodology documentation.
