Towards Carbon Neutral: Diamonds with a Conscience

What steps are the diamond industry taking to minimise their carbon footprint and ensure ecological preservation?

The natural diamond industry is often viewed through the lens of exquisite diamonds and luxurious appeal. But behind the sparkle lies a conscientious effort to align with global climate targets, minimise environmental impact and maintain biodiversity. 

This article explores the efforts being made to decarbonise the natural diamond sector and the initiatives that are reshaping its sustainability narrative

A Commitment to Decarbonisation

At the heart of the natural diamond industry’s sustainability efforts is a commitment to reducing its carbon footprint. Recognising the urgency of climate change action, leading mining companies such as De Beers Group and Rio Tinto have set themselves ambitious goals to achieve complete carbon neutrality. 

• De Beers Group: De Beers Group is committed to becoming carbon neutral by 2030.  Already achieving a 6% year-on-year reduction in energy intensity as of 2023.
  
  
• Rio Tinto: Rio Tinto has set the goal of achieving net zero emissions by 2050. Rio Tinto aims to reduce greenhouse gas emissions by 50% by 2030.

In line with global targets, these impressive numbers are the result of the collective mindset between big diamond companies and governments.

Often in developing countries where sourcing energy poses more challenges, companies are focusing their attention on developing renewable energy projects as a way to provide carbon neutral energy sources. Exploring responsible practices by engaging in carbon offsetting projects - focusing on doing right by the planet and the people paving the way for a greener future.

Changing to greener sources of energy and switching to sustainable fuel sources makes for a promising future for the diamond industry. Using alternatives such as electricity, solar, and wind-diesel farms to power their operations and switch from fossil fuels. 
 

Biodiversity and Resource Conservation

The natural diamond industry safeguards biodiversity in regions far exceeding the land used for mining. In fact, before a diamond can even be discovered - governments must grant permissions. They are accompanied with the caveat that diamond companies are obliged to be monitored for ongoing reporting and develop closure plans.

Large diamond companies follow global climate objectives including: 

• Recycling Initiatives: Approximately 84% of water used in diamond recovery is recycled, reducing the strain on local water sources.
  
  
• Waste Management: A remarkable 99% of waste generated during diamond recovery is inert rock, ensuring minimal ecological disruption.

These efforts are governed by strict environmental standards and legal mandates that include ongoing monitoring, reporting, and land rehabilitation plans post-mining.

Carbon Emissions: The Numbers

A single polished 1-carat natural diamond emits an estimated 106.9kg of CO2e—a figure comparable to driving a medium-sized car for approximately 425 kilometres. The industry is actively addressing the factors contributing to this footprint.

There are many contributing factors to carbon emissions recorded by the industry including:

• The availability of clean energy nearby mining sites.
• The efficiency and production capacity of mines and the number of diamonds extracted from each area.

These variations account for emissions across the mining stages.

Innovating for a Sustainable Future

The natural diamond industry’s decarbonisation strategy extends beyond emission reductions. Through groundbreaking initiatives, companies are actively engaging in carbon offsetting and absorption projects to remove carbon from the atmosphere:

• CarbonVault: Supported by De Beers Group, this research program explores how kimberlite—a type of rock associated with diamonds—can naturally lock away carbon.
  
  
• Wonderbag Initiative: This carbon offset program not only reduces emissions but reinvests in local communities, verified by globally recognised carbon standards.
  
  
• Kimberlite Tailings Projects: Petra Diamonds and academic collaborators are uncovering ways to transform atmospheric CO2 into carbonates using kimberlite tailings, showcasing an innovative approach to carbon capture.

These initiatives underline the industry’s commitment to innovative solutions that align with global climate goals and compensate for emissions that cannot be mitigated or replaced by renewable sources. 

A Transparent Path Forward

Transparency is central to the natural diamond industry’s sustainability efforts. Environmental permissions, legal monitoring, and public reporting ensure accountability at every stage of the diamond recovery process. By adhering to global environmental standards, the industry not only minimises its impact but also sets a benchmark for sustainable practices in mining.

A Greener Tomorrow

The journey to decarbonise the natural diamond industry is still in its beginning stages, but the progress made thus far is promising. From renewable energy projects to groundbreaking carbon sequestration research, the industry is proving that luxury and sustainability can go hand in hand.

As consumers become more conscious of their environmental impact, the natural diamond industry is poised to shine not just for its gems but also for its commitment to protecting our planet.

Diamond Future

While diamonds may symbolise love and eternity, the industry’s growing commitment to sustainability ensures they also embody care for the Earth and its future generations.

As with many global industries, achieving carbon neutrality has become an important priority. In a world where rough diamonds are transformed into extraordinary creations, it is vital to protect the biodiversity of the regions they originate from and focus on a sustainable future. By striving for net-zero emissions, the diamond industry demonstrates a collective effort between communities, land and resources - placing both people and the planet at the forefront. This commitment not only benefits the environment but also paves the way for a brighter and more sustainable future for all.
