The proven reserves of carbon available for creating C-® Carbon Negative Diamonds amount to an astounding 540 quadrillion carats, establishing these reserves as the largest ever discovered for diamond production. This colossal figure underscores the unprecedented scale and potential of C-® Carbon Negative Diamonds in the gemstone industry. 

The methodology used to calculate Proven Reserves of C-® Carbon Negative Diamonds

Here’s how we calculated this figure:

The amount of Carbon contained in Methane generated from Coal Mining:

According to the Global Energy Monitor's analysis, operating coal mines emit 52.3 million tonnes of methane per year1. Using this as a baseline, we can calculate the weight of carbon in this methane:

52.3 million tonnes of methane * (12/16) = 39.225 million tonnes of carbon (Source)

39.225 million tonnes of carbon weighs 1.96125 x 10^14 carats. This enormous number can be written out as 196,125,000,000,000 carats.

To break this down:

1. We start with 39.225 million tonnes of carbon

2. Each tonne is equivalent to 5 million carats (1,000 kg * 5,000 carats/kg)

3. Multiplying these figures gives us the result in carats

This calculation demonstrates the immense scale when converting between tonnes and carats, highlighting how even seemingly large quantities of carbon by weight translate to astronomical numbers in gemological terms.

To reduce atmospheric CO₂ from 427 ppm to 350 ppm, the amount of carbon (not CO₂) that must be removed from the atmosphere is approximately 108 billion tons (1.08 × 10¹¹ tons).

Here’s how this figure is determined:

• The total mass of Earth's atmosphere is about 5.15 × 10¹⁸ kg.

• At 427 ppm, the mass of CO₂ in the atmosphere is about 2.20 × 10¹⁵ kg.

• At 350 ppm, the mass of CO₂ would be about 1.80 × 10¹⁵ kg.

• The difference (CO₂ to be removed):
  2.20×1015 kg−1.80×1015 kg=3.97×1014 kg2.20×1015 kg−1.80×1015 kg=3.97×1014 kg of CO₂.

To convert this to tons of carbon:

• Only 12.01/44.01 of the mass of CO₂ is carbon.

• So, the mass of carbon to be removed is
  3.97×1014 kg×12.0144.01≈1.08×1014 kg3.97×1014 kg×44.0112.01≈1.08×1014 kg.

• Converting kilograms to metric tons (1 ton = 1,000 kg):
  1.08×1014 kg÷1,000=1.08×1011 tons1.08×1014 kg÷1,000=1.08×1011 tons.
