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.
