The Council for the Environment and Infrastructure (Raad voor de Leefomgeving en Infrastructuur, Rli) conducted an extensive investigation into the sources of power for the Dutch economy and concludes that traditional main ports have become less dominant. The internet economy – based around the Amsterdam Internet Exchange – and Brainport Eindhoven have become equally important. The Council for the Environment and Infrastructure is the strategic advisory board for government and parliament on the broad field of sustainable development of the environment and infrastructure. For that reason their report “Beyond Mainports“, presented to the Ministers of Economic Affairs and Infrastructure and the Environment on July 1, will be an important building stone for the next national coalition agreement.... The port of Rotterdam with its direct and indirect activities in 2015 contributed 3.1% to the Gross Domestic Product (GDP) of the Netherlands, compared to 6% in 1992. Schiphol Airport had a share of 1.4% of GDP in 2015. The Council gives no exact GDP figures for Brainport, but according to other studies this comes down to about 5% of the Gross Domestic Product.
