De Beers Group has published its 2025 Sustainability Report, highlighting progress across its Building Forever framework, including a 14% reduction in Scope 1 and 2 carbon emissions since 2021 and continued advancement toward its Science Based Targets initiative-approved goal of cutting its carbon footprint by a third by 2030.

The report, released on September 23, 2026, also detailed advances in renewable energy, nature conservation, livelihoods, diamond traceability and workplace safety.

De Beers said it supported energy trader, Envusa Energy, which brings renewable energy to Southern Africa. Through the Envusa partnership in South Africa, 48 MW of contracted renewable-energy capacity was built and energised last year, supporting the planned transition of the group’s Venetia mine toward renewable electricity supply from this year.

The miner is also advancing trials to create drop-in biofuels, progressing tyre circularity initiatives with Anglo American and Sasol, and supporting Kelp Blue, a startup growing Giant Kelp off the coast of Namibia to sequester carbon, support ocean rewilding and create local jobs and products.

Priorities for the next phase include accelerating reductions in Scope 1, 2 and 3 emissions through expanded renewable-energy capacity, electrification of mining equipment and enhanced supplier engagement to address Scope 3 emissions.

De Beers manages 375,000 acres of land for conservation across Southern Africa. Through its Okavango Eternal partnership with National Geographic, it supported the designation of Angola’s first Ramsar Wetland, helping protect the source of 95% of the water flowing into the Okavango Delta. The group aims to secure three times more land for nature than it impacts and to fund partnerships safeguarding a further 13-million acres by 2030.

The company said it supported 2.6 offsite jobs for every one job created onsite, working toward its ambition of four offsite jobs per onsite role by 2030. The EntreprenHER programme, run with UN Women, trained 500 additional women in 2025, bringing the total trained since 2016 to 3,900. De Beers also committed $70-million with the Diamonds for Development Fund in Botswana to support long-term economic diversification.

The Tracr platform, De Beers’ blockchain-backed diamond traceability system, passed the milestone of five million rough diamonds individually registered. Tracr established a new partnership with Sarine to integrate rough diamond source registration with advanced scanning data, creating an end-to-end traceability solution. The platform provided the traceability backbone for the De Beers London capsule collection using GemFair diamonds.

2025 was the safest year in De Beers Group’s history, with a 19% reduction in total recordable injury frequency rate compared with 2024 and zero work-related fatalities.

CEO Al Cook said the group sharpened its focus on ambitious sustainability targets where it believed it could make the greatest difference, aligning with partner country priorities, global standards and UN Sustainable Development Goals.

“We are proud of the progress we are making to ensure every diamond we recover creates lasting impact for people, communities and the environment, but we also understand that this requires sharp focus, deliberate action and constant monitoring,” Cook said. “As the pace of change around us increases and as the risks and opportunities ahead of us become clearer, so must our commitment to progress grow.”
