The new citizen participation uses "Citizen Science" in their hometown and nationwide to get User's feedback on places. As a result, citizens are empowered to become active in a city worth living in to collect and share data themselves and to interact with scientists. This enables them to recognize the consequences of sealing, heat, water shortages, and a lack of biodiversity, and generally, how places in their own environment affect us all.

The IPM-Popillia Horizon 2020 project aims to address the challenge of a new risk to plant health in Europe's agriculture and food safety: the invasion of the Japanese Beetle, Popillia japonica. This invasive species was introduced accidentally to mainland Europe in 2014 and can quickly spread by transportation and trade. As a species with a wide range of feeding plants, P. japonica threatens the entire agricultural sector, urban landscapes, and biodiversity in invaded areas.

Fridays for Future see itself as a horizontal, grassroots grassroots movement that acts apolitically and refers to science for the facts.
