Yes, we've drawn a lot of similarities with how oil and gas companies have been covering up and denying climate change. We know they had knowledge of climate change since the 1950s. Of course, this is the same way that tobacco companies had been marketing and pushing cigarettes as healthy for many years.
Greenwashing is sometimes called the new denial. Instead of continuing to deny the impacts of climate change, which they know is no longer possible, they are proposing and putting forward false solutions.
Another option I hadn't mentioned in what other jurisdictions are doing is completely banning the advertising of some highly polluting products. There are products, such as tobacco, that we know should not be promoted at all.
This would be another very effective mechanism for addressing greenwashing by the most polluting sectors.
