Many countries are refusing to sign a death certificate for small island states, which is good. We should also note that this isn't just about small island states - while they're on the front line, and may be first to drown, ultimately all of us are at risk. If climate change is not stopped, we face fires, floods, famines, sudden and large rises in sea-level, mass-migration, and ultimately a collapse in global agriculture and the civilisation it allows. And fossil fuels are the weapon which is causing this.
I use that word – “weapon” - deliberately. We think of fossil fuels as just an energy source, something to run the car or a factory. But like tobacco, every ton of fossil fuels we use is doing us damage. That damage is global, indiscriminate, and - if not stopped - promises to be every bit as destructive as global nuclear war.
Current models for a fossil fuels treaty use the Treaty on the Non-Proliferation of Nuclear Weapons as a model, adopting its pillars of non-proliferation, phase-out, and a just transition. But the use of nuclear weapons is a crime, and those who use them are criminals and terrorists, and we need to start adopting that thinking for fossil fuels as well. So we need a fourth pillar: criminalisation. We have models here too: the chemical weapons, anti-personnel mines, and nuclear weapons treaties all require their parties to criminalise violations on their territory or by their citizens (so e.g. its a crime for a kiwi anywhere in the world to develop, trade, use, or facilitate chemical weapons). We need to adopt such measures for fossils fuels after they have been phased out - or outside of a phase-out program (so e.g. in countries which refuse to be a party).
Obviously, not every country will sign such a treaty - the criminal petro-states won't. Which is why we need a fifth pillar: financial sanctions against fossil fuel companies and executives and their enablers, so that criminals who remain outside the phase-out regime cannot openly sell their climate weapon or enjoy the profits of their crime. we have a useful model here too: the current sanctions against oligarchs and companies supporting Putin's criminal invasion of Ukraine. If the fossil fuel industry won't phase down, that's how we need to treat them.
People might object to the framing of fossil fuel executives and traders as criminals, but these people are deliberately and knowingly trying to kill us for profit. They are deliberately and knowingly trying to burn our homes, drown our cities, and starve and bake us to death. What else should we call them?
