Creating a city that is both dense and green could result in conflicts. The aim with this report is to describe how the municipality of Malmö works with densification and at the same time creating green environments. Also, the aim is to describe how densification and greenery in the city are problematized by researchers. It was shown in the empirical study that it is a political directive to create a dense and green cite. To be able to create this, all of the interviewees refers to the comprehensive plan of Malmö. The methods the municipality of Malmö uses to create green environments during densification varies from different projects, considers John Lepic. The results in the literature survey show that greenery often is identified as a key ingredient of a sustainable city (Boverket 2002; Jim 2004). In order to systematically create a greener city the spatial planning and data produced in connection with it are important tools (Nordmalm, et al. 1999). To create exciting and interesting environments both quantity and quality are important (Jim 2004). Greenery could be introduced in cities in many ways. Even if the wildest ideas may not be reality, it is possible to get inspiration from these ideas and with their help find new solutions.
