I give this example as I previously worked at a big European REIT. My job was to implement renewable energy across the portfolio which on paper was a no-brainer due to legislation and grants / feed in tariffs etc.

We got huge pushback from every angle with the local teams, people paying lip service to drag it out and delay. Eventually I got to the root cause... The capex had to come out of the business unit, and the payback would negatively affect their KPIs and bonus. Next time I came across this kind of issue, I asked to see the incentive structure before approaching anyone.
