The latest fighter jet developed by the US, the F-35, is reported to burn 5,600 litres of fuel an hour. It would take 1,900 cars to guzzle a similar amount of fuel over the same period.
Norway, like many other countries, has been queuing up to get its hands on this new-generation jet. According to the Norwegian newspaper Dagsavisen, the total emissions by the Norwegian military over the next decade will rise by 30 percent as a result of its F-35 purchases alone.
As well as discounting the environmental harm caused by military equipment procurement and supply chains, countries are also excluding the significant impacts of conflicts and wars.
Each year of the US occupation of Iraq that began in 2003, for example, is conservatively estimated to have generated emissions equivalent to putting an additional 25m cars on the road.
Unlike the farming and logging industries, or the manufacturing industries, or the fossil fuel industries, efforts to curb the growth in military spending - let alone reverse it - are off the table at the COP26 summit.
And for that, Washington has to take the major share of the blame.
Its "defence" budget already comprises about 40 percent of the $2tn spent annually on militaries worldwide. China and Russia - ostensibly the two bogeymen of the COP26 summit - lag far behind.
The government of Boris Johnson unveiled last year what it called "the biggest programme of investment in British defence since the end of the Cold War". Britain is no outlier. After a short-lived "peace dividend" caused by the break-up of the Soviet Union, global military expenditure has been on an almost continuous upward trend since 1998, led by the US.
Paradoxically, the upturn began about the time western politicians began paying lip service to tackling "climate change" at the Kyoto summit.
US military spending has been rising steadily since 2018. It is set to continue doing so for at least another two decades - way past the deadline set by climate scientists for turning things around.
The same global upward trend has been fed by a surge in military expenditure by Middle Eastern countries - notably Saudi Arabia and the UAE - since 2013. That appears to reflect two trends rooted in Washington's changing approach to the region.
First, as it has withdrawn its overstretched occupation forces from Iraq and Afghanistan, the US has increasingly outsourced its military role to wealthy client states in this oil-rich region.
And second, as Israel and the Gulf states have been encouraged to forge closer military and intelligence ties against Iran, these same Gulf states have been allowed to play military catch-up with Israel. Its famed "qualitative military edge" is being gradually eroded.
Propping up this Middle East arms spree is the UK, which has been exporting to the Saudis, and the US, which heavily subsidises Israel's military industries.
Power competitionAll this means that while western politicians promise to cut emissions at COP26, they are actually busy preparing to increase those emissions out of view. Ultimately, the problem is that little can be done to green our militaries, either substantively or through a greenwashing makeover. The military's rationale is neither to be sustainable nor to be kind to the planet.
