<h1>Fossil CO<span class="subb">2</span> emissions</h1>
<h2>Relationships between datasets</h2>
<p>Because the largest source of fossil CO<span class="subb">2</span> is the oxidation of fossil fuels, energy databases are a critical starting point for emissions inventories. These are shown on the left of the figure. The next largest source of fossil CO<span class="subb">2</span> emissions is from the decomposition of carbonates, for example in cement production. A source not shown on the figure is so-called fugitive emissions, which are mainly ex-market combustion (flaring of natural gas) but also the release of long-stored CO<span class="subb">2</span> in geothermal energy production. Partial blue shading of some secondary datasets is meant as an approximate indicator that these datasets combine primary with secondary estimation.</p>
