Why Villainize Methane to Begin With?
Before we hyperventilate over the apparent underestimating of our energy sector’s methane emissions, it is worth being aware of the “big picture” of methane.
The majority of methane emissions are from natural sources—specifically, tropical wetlands—then agriculture and landfill and the energy industry. The energy sector is not the main emission source.
In all of these sectors, Australia is also a very small emitter compared to other countries. This has been especially notable recently, when sudden, large methane emissions have been traceable to specific large-scale leak events, such as the Nordstream Pipeline ruptures.
While methane is continually emitted into the atmosphere, it is also continually removed from the atmosphere by natural processes so that the amount that is actually accumulating is a small fraction of what is entering.
Methane levels have been increasing recently at an increasing rate. Yet these recent changes have been attributed to an increase in natural wetland emissions and, ironically, a decrease in NOx pollution (nitrogen oxides). The process that breaks down NOx pollution from the air also removes methane.
Energy is a fundamental cost encapsulated in all modern productivity. The safeguard mechanism, even with its current targets, is already an impost on the sector that is likely to drive costs upwards across all industries.
Unlike CO2, methane is at least a useful commodity; capturing methane and using it (or selling it) for energy is worthwhile. The industry does not lightly throw methane away.
Decreasing emissions will be difficult in places where the industry is already efficient. The emitters will have to purchase emission offsets.
They don’t mind this, they will simply pass costs onward, which will drive up fuel prices at a time when fuel is scarce, and prices are already high.
The IEEFA analysis and conclusions are taking another opportunity to seek to punish Australia’s energy sector. They ought to realise that the more we hit our energy sector, the more we hit ourselves.
