A little vague but, fascinating. Congrats on trying something new. I've been in Orange most of my life.
The bottom-line is a very powerful argument. Re-frame everything in terms of its monetary benefits.
Often Orange/Green/Yellow will align in win-win outcomes. Print less paper, use less electricity etc. helped push environmentalism as much as Al Gore's documentary.
Ford initiated the 5-day workweek to ultimately sell more cars: "It is high time to rid ourselves of the notion that leisure for workmen is either 'lost time' or a class privilege,"
Back up your ideas with rigorous science.
I started meditating when I read a book by a Google employee about it. Then researched recent scientific findings.
Same goes for breathing exercises, natural remedies, willpower exercises, journaling etc.
Present them as the ideas of competitors and people they admire. Show them clips or images to shock them. It's more convincing if it ideas come from someone you think as 'one of your own'. I've been listening to:
News reader, Dan Harris (who sounds like a workaholic) about meditation.
Entrepreneur, Ed Mylett about selflessness.
Elon Musk, about contributing your special set of skills to improve the world.
Conan O'Brien, about caring for others.
Search for B-Corp, it's a relevant idea.
Emphasise results, then present a clear formula and ways to measure progress.
They might oddly enjoy these things if they use familiar software/tools.
Numbers, must be part of accountability somehow. Or use checklists.
Discuss vision and big picture.
What is hard work and money really for? They should answer of their own volition that they seek Green values. Most people do, but say they don't have the time or are wistful about it.
Good luck!
