In 2025, mining producers worked on their continuous improvement plans by

integrating multiple climate related actions into their operations:

• All SBG producers implemented measures such as carbon emissions quantification and water recirculation practices, demonstrating full participation in climate performance enhancement.
• Throughout the year, they engaged in 33 climate change training workshops – five organised directly by the producers and the remaining sessions led by the SBG technical team, thus strengthening their technical capacity to address climate risks.
• Producers also carried out soil recovery initiatives and tree planting programmes, involving not only the reintroduction of native seedlings but also long-term maintenance and protection to ensure effective ecosystem restoration.
• Twelve producers installed solar powered lighting in camps and along roadways, marking an initial step toward integrating renewable energy into their operations.

SBG supply chain carbon emissions indicators:

In 2025, all SBG accredited mining producers completed quantification of their carbon emissions (Scope 1 & 2). Among them, 83% applied nationally standardised methodologies, specifically Colombia’s UPME National Carbon Footprint Calculator and Peru’s national Carbon Footprint tool. The remaining producers relied on third-party organisations to perform their emissions calculations.

The latest SBG accredited mine results show carbon emission intensities ranging from 69 to 3,345 kg CO₂e per ounce of gold. Clear differences appear across mining types: open-pit operations exhibit the highest emissions, ranging from 245 to 3,345 kg CO₂e per ounce, while underground producers show the lowest, ranging from 69 to 206 kg CO₂e per ounce.

SBG supply chain water stewardship indicators:

All SBG accredited mining operations systematically measure their total water consumption and apply water recirculation practices. On average, these practices allow operations to recirculate 86% of the water used, significantly reducing their dependence on external water intake.

In several cases, recirculation rates reach 90–100%, enabled by both the typology of the mining method and enhanced water management controls of the operations.

Importantly, six operations function within fully enclosed processing pools, where water remains continuously available and is entirely recirculated in a closed loop. One operation relies exclusively on natural runoff and infiltration, enabling it to operate without abstracting surface or groundwater.

Annual water use also varies significantly across mine sites: the smallest intake is 3,500 m³/year with a 13% recirculation rate, while the largest records 1,4 million m³/year with a 90% recirculation rate in this particular case.
