This is according to the company’s Report to Society, published on Tuesday.
De Beers also improved its environmental performance, with reductions in energy consumption and carbon emissions.
More specifically, De Beers invested $24.3 million in development training for its workforces in 2015, a 30% increase on the $18.8 million the company invested in 2014.
The company also invested $28.2 million in social projects, which benefited 47 800 people in its producer countries – an increase from the $27.6 million it invested in 2014.
The report also shows:
- Safety performance continued to improve in 2015, with De Beers achieving a 15% reduction in the total recordable case frequency rate;
- The company reduced its environmental footprint, achieving savings of $6.8 million as a result of reduced energy consumption and carbon emissions over the last two years;
- De Beers continued to demonstrate compliance with performance standards in 2015, becoming re-certified with the Responsible Jewellery Council and marking the 10th anniversary of its own externally assured compliance programme – Best Practice Principles – which now covers 320 000 people across the diamond pipeline, in 72 countries.
Philippe Mellier, Chief Executive, De Beers Group, said: “Investing for the long term, driving positive change and unlocking opportunities through diamond development are at the core of what we do and I am very proud of our performance in these areas in 2015.
“However, positive performance must not be seen as grounds for complacency and we will redouble our efforts in 2016 so that diamonds continue to have a positive and lasting impact for our partners, our employees and the communities in which we operate.”
