Scotland could become one of the first countries to establish a specific crime for mass environmental destruction as championed by late Scots barrister Polly Higgins.
I think we need to address this not just at individuals or corporations, but at nation states in which those individuals reside and are licensed.
We need to kick them in the wallet. Allowing rampant pollution? Extra trade tariffs, and exclusion from various international groups/events. Complicit in rampant pollution? Punitive economic Sanctions, and loss of access to certain technologies, financial networks, etc.
Because the capable ones to enforce these sanctions are the main culprits of the climate crisis and it would be incredibly convenient for them to use these laws to get even more ahead of underdeveloped nations.
Unless thats exactly what you want, keep the exploited poor and the exploiters rich. Think better.
