The work of the Gdansk-Gdynia-Sopot Metropolitan Area is handled by committee meetings which focus on different themes. They discuss and implement specific projects such as the joint purchase of goods and services  or the preparation of development plans and investment funds which cover several local authorities.

A key element of cooperation is the exchange of experiences and good practice in the projects carried out by local governments, public procurement rules, financial discipline, etc.

Since February 2014, the office of the Association has acted as the headquarters of the Association of Integrated Territorial Investments, which is a new instrument for metropolitan cooperation.
