Tropa Verde was set up in Santiago de Compostela, Spain in 2015, and seeks to encourage environmentally responsible behaviour. Its goal is to promote recycling by rewarding environmentally-friendly practices.

In 2018, the City of Antwerp kick-started the Circular South project. The aim is to encourage more efficient use of energy, water, waste and materials by the citizens of the New South district of Antwerp through an innovative community-driven approach.

In February 2016, the government of Lithuania implemented a “deposit return system”, to give consumers an incentive to return used beverage containers for recycling. To combat litter and increase collection and recycling rates, consumers would pay a deposit amount of €0.10 when purchasing eligible drink containers, to be refunded when the empty container is returned for recycling.
