If you haven't already, you might want to take a look at the book "Third Industrial Revolution" by Jeremy Rifkin. Or, to save yourself time and money, take a look at some videos of him on Youtube.
To make a long story short, Mr. Rifkin is an economist who has worked with governments around the world to put in place a "third industrial revolution" that revolves around renewable energy and energy storage.

Convert carbon dioxide (CO2) weight to carbon (C) weight


CO2/3.67 = C 


ex: 40 GtCO2 ≈ 10.9 GtC


1 Gt (Gigatonne) = 1 billion tonnes

1 tonne = 1,000 kg


Also: 1 Pg = 1 Gt


1 Pg (Petagram) = 1 quadrillion grams


Soil specialists tend to use Pg, as they are used to working with gram units per square meter of soil area. Atmospheric specialists tend to use Gt. 

Convert carbon emissions to ppm atmospheric CO2


GtC/2.12 = ppm

To convert emissions of carbon to atmospheric ppm CO2, carbon sinks must be taken into account. 

So far, terrestrial and oceanic sinks have taken up about 50% of CO2.



ex: 40 GtCO2 emissions ≈ 10.9 GtC

10.9 GtC/2.12 ≈ 5.14 ppm CO2 before accounting for sinks

5.14 ppm CO2 x 0.5 ≈ 2.57 ppm CO2 after accounting for sinks
