RAPAPORT… The major diamond miners have weighed in on the debate
over which diamonds are more ethical, claiming their production uses less than one-third
of the energy it takes to create a diamond in a lab.
The operations of companies that make up the
Diamond Producers Association (DPA) emitted an average of 160 kilograms of
carbon dioxide (CO2) per 1 carat of polished diamonds produced in 2016, according
to a study commissioned by the DPA and carried out by Trucost ESG Analysis,
which is part of S&P Global. That compared to the estimated greenhouse gas
emissions of 511 kilograms of CO2 for the average 1-carat lab-grown polished stone.
A debate has ensued in recent years over which diamond is
more environmentally friendly (or harmful), with many lab-grown-diamond
companies claiming to have the greener product in their advertising. In April,
the Federal Trade Commission (FTC) warned several synthetics producers against
using claims such as “eco-friendly,” “eco-conscious” or “sustainable” without
qualification.
“This independent
research report breaks outdated stereotypes and misconceptions and identifies
the next set of challenges that must be met to continue
to evolve and improve as an industry,” said DPA CEO Jean-Marc Lieberherr in a
statement on Thursday.
The DPA members have set goals to reduce their carbon
footprint, while the DPA will monitor their progress in achieving the United
Nations Sustainable Development Goals.
The report, titled “The Socioeconomic and Environmental
Impact of Large-Scale Diamond Mining,” highlights the benefits to employees of
DPA members, the impact those companies collectively have on the communities in
which they operate and their environmental stewardship.
Together, the miners generate more than $16 billion in
net socioeconomic and environmental benefits through their operations, Trucost
reported.
Despite significant progress toward responsible and
transparent practices over the past 15 years, the current reality of the
diamond-mining sector remains largely unknown, the authors noted. “This report
provides access into a highly scrutinized, yet largely misunderstood sector,”
the report added.
The DPA consists of seven companies, with Alrosa, De Beers, Rio Tinto and Petra Diamonds participating in the study. Dominion Diamond Mines, Lucara Diamonds and Murowa Diamonds are the other members.
The Lab Grown Diamond Association did not reply to a
request for comment from Rapaport News by press time.

Diamond Miners Push Back on Ethics Claims
The Bottom Line
- The Diamond Producers Association (DPA) reports that natural diamond mining emits an average of 160 kg of CO2 per carat, compared to 511 kg for lab-grown diamonds.
- The DPA study highlights socioeconomic and environmental benefits from mining operations, generating over $16 billion in net positive impact.
- The Federal Trade Commission cautioned synthetic diamond producers against unqualified environmental claims, reflecting ongoing debate over diamond sustainability.
