US$329bn in market capitalization (88% of total amongst responding diversified miners). Filter for diversified miners Filter for largest emitters and highest market cap CDP respondents Largest non-responders: Norilsk Nickel, Grupo Mexico and KGHM Polska Miedź

11. www.cdp.net | @CDP Scope of research: key areas Page 11  Energy efficiency: against a backdrop of deeper mining and lower ore qualities, which require greater energy to process, and increasingly remote locations of mining operations, with potential grid and transport constraints, leaders in energy efficiency will gain a competitive advantage and potentially enhanced earnings. Using emissions profiles as proxies, we assess each company’s historical performance and future reduction targets.  Water resilience: we assess the companies’ exposure to water risk and how aware they are of these risks. We undertake facility-level analysis to assess which companies are at a greater risk of future production issues due to water stress.  Coal exposure: coal faces tightening regulation and increasing competition from cleaner alternatives with implications for its economics. We examine the companies’ exposure to both thermal and coking coal.

12. www.cdp.net | @CDP Scope of research: key areas Page 12  Carbon cost exposure: we assess the emissions-related carbon cost exposure of mining companies in our study and the potential impact on earnings under current and future carbon price scenarios.  Carbon regulation readiness: using InfluenceMap’s proprietary analysis, we assess each company’s actions in supporting or opposing climate legislation. We believe that supportive firms are most likely to benefit from progressive climate agreements.

14. www.cdp.net | @CDP Super-League Table Page 14  Ranks companies based on a number of emissions-related metrics which in aggregate could have a material impact on company performance.  Proxy for business readiness in an industry where environmental regulations are becoming more stringent.  From a climate risk perspective companies towards the bottom of the table are possibly higher risk investments than those towards the top.  Data sources include CDP databases, companies’ annual and CSR reports and external data from organizations such as WRI.

16. www.cdp.net | @CDP Key findings  The diversified mining industry has significant work to do on emissions-related topics, areas of concern include:  Lobbying: the industry’s lobbying activities are generally against low carbon regulation. Only two companies (Antofagasta and Vale) were found to be mildly supportive of low carbon regulation, the remaining nine companies appear to be obstructive.  Coal exposure: more than half of the companies are involved in coal production, and together they represent 40% of the global seaborne (export) market in coking coal and 27% in thermal coal.  Emissions reduction target setting: the diversified mining industry compares poorly with other industry groups featured in our previous research reports. Only six of the 11 companies have meaningful emissions reduction targets and none of the companies have both an absolute emissions and intensity target. Page 16
