ALROSA DIAMONDS

carbon neutral

Their production absorbs more CO₂ than it releases into the atmosphere.

THE CLIMATE IS CHANGING FAST AND SERIOUSLY

To avoid catastrophic consequences for the Earth's biosphere, international experts estimate that global warming must be limited to 1.5°C. This goal was set by the 2015 Paris Agreement. To achieve this, carbon dioxide emissions must be reduced by 45% by 2030 compared to 2010 levels, and reach net zero by 2050. Otherwise, we face extreme weather events, thawing permafrost, ocean acidification, and the collapse of entire ecosystems.

Over the past 100 years, the concentration of greenhouse gases has increased 25-fold.

If current trends continue, the consequences could become irreversible as early as the second half of the 21st century.

Today, what matters is not only what is produced, but also how

Responsible companies strive to reduce their carbon footprint, and consumers increasingly want to understand the real climate impact of the goods they buy.

Where do diamonds come from?

Natural diamonds are mined from diamond-bearing bedrock — kimberlite

Kimberlite is an igneous rock that formed billions of years ago deep underground and brought diamonds to the surface during ancient eruptions. But kimberlite is interesting not only as a source of diamonds.

Kimberlite can naturally absorb CO₂ from the atmosphere through a process called carbonation

  • kimberlite minerals react with water and CO₂ from the air
  • carbon dioxide is converted into stable calcium and magnesium carbonates
  • carbon gets locked into a solid mineral form

This is not a hypothesis or a model. It has been proved by three years of research conducted by ALROSA specialists together with scientists from Moscow State University. Direct measurements were taken at ALROSA's diamond deposits in Yakutia and the Arkhangelsk region, which confirmed this effect.

This process has no reverse effect

The absorbed CO₂ does not return to the atmosphere — it remains locked in stone forever.

ALROSA's technologies turn all extracted ore into a natural filter for CO₂

Extracted and processed ore purifies the atmosphere

The cleaner the atmosphere, the better for the climate, as the climate accumulates changes

DIAMOND MINING ENHANCES CARBONIZATION

In nature, carbonization occurs slowly, but diamond mining accelerates the process: when kimberlite is extracted from the depths and finely crushed during diamond recovery using water, it actively interacts with air and water.

As a result, the natural process of CO₂ absorption accelerates sharply. In effect, diamond mining activates and amplifies a natural mechanism that existed long before humans.

In nature

Kimberlite is locked deep within the earth

When extracted from the ground

Chemical reactions between kimberlite and air are activated

During diamond mining

Kimberlite is crushed during processing, increasing the surface area in contact with air

The use of water during the crushing and storage of kimberlite rock accelerates the reaction with air

THE SCALE OF THE EFFECT — IN CLEAR NUMBERS

During ALROSA's diamond mining process, approximately
≈ 1,000,000 tons of CO₂ equivalent is absorbed annually

This exceeds all greenhouse gas emissions associated with the company's diamond mining operations over the same period.

1,000,000 tons of CO₂

Annual CO₂ absorption during ALROSA's diamond mining is comparable to the annual CO₂ absorption of forests covering ~400,000 hectares

A full dump truck of kimberlite absorbs 6 tons of CO₂

A full dump truck of kimberlite absorbs 6 tons of CO₂

130 tons of kimberlite ore in the body of a mining dump truck absorb up to 6 tons of CO₂ — more than an average passenger car emits over many years of operation

The balance is not zero — it is negative

The effect is confirmed not by theoretical calculations, but by scientific research conducted at ALROSA's industrial facilities

AN INDUSTRY LEADER'S CONTRIBUTION TO THE FUTURE

ALROSA accounts for more than 30% of global diamond mining

This means that at least every third natural diamond in the world is already carbon neutral today.

ALROSA BECAME THE WORLD'S FIRST MINING COMPANY TO

Scientifically prove the carbon neutrality of its products

Undergo independent international verification

Achieve carbon neutrality without purchasing carbon credits

The company is setting a new industry standard and redefining what mineral extraction can look like in the 21st century.

ALROSA became the world's first mining company whose product — natural diamonds — has been officially recognized as carbon neutral. International verification confirmed that during diamond mining, CO₂ absorption exceeds all greenhouse gas emissions.

Achieving carbon neutral production inspired ALROSA to launch Russia's first CCS-CDR project to increase the intensity of CO₂ absorption.

CCS — Carbon Capture and Storage — technologies for capturing and retaining carbon in inorganic form
CDR — Carbon Dioxide Removal — technologies for removing carbon dioxide
Scientists conducting measurements at ALROSA's Mirny-Nyurba Mining and Processing Plant observed that when two diamond-bearing rock types — primary kimberlite and alluvial sands — are mixed, carbon dioxide absorption ceases. When the primary rock is separated from the sands, CO₂ absorption resumes. This means that by upgrading its technology, ALROSA will be able to increase the volume of carbonization.
At full capacity, this CCS-CDR project may absorb up to 26,000 tons of CO₂ annually, generating 26,000 high-value carbon credits. Revenue from the CCS-CDR project will be directed toward enhancing ALROSA's carbon neutrality and environmental programs.

CAN LUXURY GOODS BE CLIMATE FRIENDLY?

For too long, luxury has been tied to excess and climate impact. ALROSA's natural diamonds are changing that story.

Every so often, technology doesn't compete with nature — it preserves it. Natural diamonds are not only a symbol of value and beauty, but also an example of how luxury goods can be a benchmark for environmental purity with a zero climate footprint.
