To generate carbon credits, a project’s emission reductions need to be measured and quantified. This involves calculating how much CO2 (or equivalent GHGs) has been avoided or removed compared to the baseline. The calculation depends on the specifics of the project and involves standard methodologies set by certifying bodies. It is important to note that although the term ‘carbon credits’ is applicable, it is actually a term that applies to all GHGs – hence the mention of ‘or equivalent GHGs’.
With the ability to measure a range of GHGs, the S4 PULSAR uses reference method gas analysis for important gases such as methane and nitrous oxide. Why are they important? Well, methane is about 25 times more powerful as a GHG than carbon dioxide, and nitrous oxide is 300 times more powerful!
