Because employers do not really care about the environment. They’re pretending to because they think supporting the cause positively impacts their revenue. When they have a choice to make an impact, like now, they pass.
Yep. You have to make the environmental goal correspond to a money goal of some sort.
And this can be exceptionally difficult because it can be almost impossible to actually work out the long-term effects of things like "more people should work from home". It's easy to say "shutting down a coal power plant will reduce emissions" because they're so bad, but more remote workers could result in MORE pollution if it enabled more "working holidays" and therefore more flying. And that's only one tiny aspect of all the long-term changes that could occur.
The best part is when they deflect blame onto the individual and tell us to "do our part" while they guiltlessly continue their polluting practices. Just like they do with mental health.
