In the Dutch city Utrecht 316 bus stops now have a green roof. They do not only look great, they also help capture fine dust, storage of rainwater and provide cooling in the summertime. 

 

Also recently Utrecht has replaced 10 diesel buses for electric buses. Utrecht aims to only operate CO2 neutral buses by 2028. In the meantime, Utrecht incentivizes bus drivers to adapt to a more environmentally friendly driving style. The buses register how efficient and comfortable each bus driver operates the bus, and based on how well they drive, they can "win" prizes the cleaner, more comfortable and safer they drive.
