This roadmap presents a framework for climate-smart MSP aiming to respond to the urgency of decarbonization that is needed to meet the meet the Paris Agreement temperature goal to limit global warming to 1.5°C. Specifically, it strives to support a more rapid, socially acceptable and just implementation of offshore renewable energy as one of the key clean energy sources for getting to net zero as quickly as possible. As such, the roadmap encourages not only an increase of offshore renewable energy — with offshore wind energy being the most promising option currently — but also its co-use with other climate-smart uses of the ocean and climate solutions — such as natural carbon sinks and nature restoration, low-trophic aquaculture and other innovative forms of renewable energy.
