EY provided limited assurance on Scope 1 and 2 GHG emissions for 2023, with GHG Protocol alignment confirmed. FY2024 prelim report references GHG intensity reduction and 80.6% renewable electricity but does not disclose absolute Scope 1/2 tonnes publicly. For a mining company operating eight mines with heavy diesel equipment, absolute Scope 1 emissions likely exceed 300,000 tonnes CO2e annually.

No Scope 3 emissions data disclosed in any publicly accessible Fresnillo document. No supplier engagement programme on emissions identified. For a mining company with a global supply chain covering cyanide, explosives, fuel, steel, equipment, and downstream smelting, Scope 3 would be material. No CDP submission found.

No multi-year absolute Scope 1 or Scope 2 emissions trajectory published. Renewable electricity increased from 53.3% in 2023 to 80.6% in 2024, implying Scope 2 reduction, but Scope 1 (diesel-dominated) trajectory is unreported. Production stable 2023–2024. Intensity improvements cannot substitute for verified absolute reduction data.

Fresnillo achieved 80.6% renewable electricity in FY2024, exceeding its 2030 target of 75% by six years, primarily via wind contracts in Mexico. Dual-fuel (diesel/LNG) infrastructure at La Herradura expected 2025. However, mining fleet remains predominantly diesel-powered with no electrification plan disclosed.

Fresnillo operates in Sierra Madre Occidental and Sonoran Desert. A 977-hectare conservation area at Ciénega exists; company is WildCorp member. All projects stated outside protected areas. However, no quantified biodiversity footprint, no TNFD disclosure, and no independent verification of outcomes found. Mining concessions span 2.1 million hectares.

Fresnillo states use of impermeable membranes in heaps and tailings, hazardous waste managed under Mexican law, and progressive rehabilitation pursued. New Juanicipio tailings facility built to Mining Association of Canada standards. Revegetation programmes exist. No quantified waste metrics, no circular economy targets, or measurable waste reduction targets disclosed.

Four-pillar water strategy includes efficiency, pollution prevention, watershed engagement. Company invests in water treatment and voluntarily returns 300,000 m³ annually to communities. Uses Aqueduct for water-stress assessment. Municipal wastewater used at two operations. No absolute consumption volumes (megalitres/year) publicly accessible, no year-on-year reduction trend found, no independent verification identified.

Fresnillo has no SBTi commitment and has stated 'commitment to setting science-based targets in the future' since at least 2022 without lodging formal commitment. FTSE4Good excluded company in 2022 explicitly due to insufficient emissions targets. Only concrete target: 75% renewable electricity by 2030, already achieved at 80.6% in 2024. No absolute GHG reduction or net-zero targets.

Fresnillo publishes integrated Annual Report with EY limited assurance on Scope 1, Scope 2, GHG intensity, and energy KPIs for 2023. Board-level sustainability oversight exists. FTSE 100 listed under UK SECR. No standalone sustainability report, no CDP participation, Scope 3 unreported, no executive compensation linkage to sustainability found. Excluded from FTSE4Good since 2022.

Fresnillo excluded from FTSE4Good Index in 2022 and remains excluded, with FTSE Russell explicitly citing insufficient progress on carbon emissions targets and lack of science-based target-setting. Company confirmed this in own 2022 prelim report. No regulatory fines, tailings failures, environmental prosecution, or active climate litigation identified. No evidence of anti-climate policy lobbying found.
