And yet changes to UK environmental policy have actually helped bring the UK's carbon emissions down to 19th century levels (yes, caveats about where our stuff is made nowadays apply) and companies with more money than all citizen environmentalist groups put together plough far more money into efficiency savings and renewables than disinformation campaigns.

There's a plausible argument that this isn't enough, but it's difficult to see how an unpopular activist group with little to say on actual solutions to climate change is likely to improve upon this status quo, especially since they actively ruled out engaging with supportive businesses because ultimately the aesthetics of grassroots protest appealed more to them than the opportunity to press for tangible emissions reduction.
