It wasn’t the only factor in us not having kids but it tipped the balance.
I used to work for an environmental campaigning organisation. Who were much less carbon conscious on their own activities than my previous employer in higher education.
I was shocked by that having been in amateur activism for a while and seen the level of sacrifice people there were making.
At the environmental organisation there were individual people making substantial efforts and sacrifices.
Other who thought things like going on a driving tour of Europe rather than flying there have them impeccable credentials.
And at that time (just over a decade ago), the organisation was only just getting round to thinking about how often people flew for work etc, into making their building energy efficient etc. I’d seen such moves happen in my former employer several years before and with muss less fuss, arguing and squirming.
They also made recommendations for the public about which e.g. IT equipment was the most environmentally friendly buy and totally ignored those recommendations in relation to their own purchasing.
More tellingly, there was significant internal discord over whether or not to commit the significant reserves held by the organisation (and linked organisations- some fairly complex accounting going on) to the fight against climate change.
Basically the younger campaigners wanted to go balls to the wall and spend the money whilst the older staff wanted to maintain reserves to ensure the organisations long term survival.
Significant resource was being expended on exploring and moving into the field of refugee work, as the organisation thought that would be a significant growth area for them when climate changes efforts failed and numbers of refugees from climate change rose. And that there would be considerable funding available for this purpose from both private donors and institutional givers.
There was significant internal discord about the amount of resources being allocated to this shift, and that plans for refugee facilities and transport contained significant provision for prioritising the housing and safe transport of senior members of the organisation, rather than concentrating more fully on necessary field staff and refugees.
I only lasted a few months before exiting in disgust.
