Second Nature is supporting an ambitious project by IUCN and Holcim to bring nature into cities by driving and promoting its inclusion into building standards. The project is part of a global strategic partnership between IUCN and Holcim. 

Building on Second Nature's research on cities around the world, we are analyzing global best practices on biodiversity-related building standards and then evaluating selected Western and Central European cities. The findings will be presented to city policy makers, construction industry leaders, and other stakeholders at upcoming international events. The analysis will be structured around themes and targets of the Berlin Urban Nature Pact (especially the co-habitation section), an initiative by a number of cities to lead the transition towards bold biodiversity action.
