Make it clear you will support their increased financial costs.  If its a restaurant, buy a couple 100 worth of their gift cards.  If you pay monthly to go to a gym, tell them if they make changes, you will prepay for 2 years 30% above their current rate.  Maybe get a group of people to pool their money to give a business a zero interest loan to upgrade their lights to led.  

Just make it clear you understand this will impact their bottom line and assure them you and others will 100% be there to absorb the cost.
