The Baltic Cities Environmental Bulletin (2012) emphasizes the urgent need for local authorities in the Baltic Sea region to tackle climate change through sustainable practices, as cities contribute significantly to global emissions. The document highlights successful initiatives, such as Arendal's climate partners network and Rakvere's efforts to promote cycling, which aim to reduce CO2 emissions and improve urban environments. It calls for greater collaboration among cities to address the climate challenge and shares best practices for sustainable urban development.
