The hype has also been great at fueling economic activity which contributes even more across a wide range of sectors.

We know how to reduce carbon emissions immediately, we did a great job of it 3 years ago, we just don't like the answer: reduce economic activity.

Consume less, produce less, work less, spend less. These things will do more to reduce CO2 emissions than if everyone rushed out and bought electric cars (in the US ~oil~ gasoline consumption has been positively correlated with electric car ownership).

But we don't want that, and more importantly, the stock market doesn't want that. I think most people would be fine with reduce work and reduced consumption (to a point), but the people invested deeply in the status quo tend to have asymmetric influence.
