Climate change

For our operations and the communities where we operate, climate change is no longer a theory. It is a reality with serious and permanent implications. That is why we work to minimise our contribution to climate change while mitigating its most significant consequences.

In 2008, we conducted a study of the climate change risks and opportunities that De Beers faces. The two most serious threats to our mine were identified as reduced water availability and flooding because of extreme weather. This longer-range work has informed our efforts to reduce our water and energy consumption.

More recently, we have worked in partnership with the Camborne School of Mines at the UK’s University of Exeter to model climate risk in more detail at Venetia mine.

Project Terra is our key approach to reducing our water, energy and carbon emissions impact, through a set of long-term reduction targets. These include a set of commitments for 2020: to reduce water usage by 20 per cent, energy use by eight per cent and carbon emissions by nine per cent.

So far, progress against our targets has resulted in total savings of 0.3 billion litres of water in 2016 and 800,000GJ of energy and 73,000 tonnes of carbon emissions since 2015. In total, this has saved the company US$10.6 million since 2014.

We calculate our greenhouse gas emissions using the World Resources Institute’s Greenhouse Gas Protocol and carbon conversion factors for purchased electricity, as relevant to each site. Standard conversion factors are used for liquid fuels across all companies within the Anglo American Group.
