The key enabler of international trade, shipping is heavily reliant on fossil fuels and responsible for approximately 2% of global carbon emissions. For the sector to reduce its emissions in line with climate change objectives, a wholesale transition is required from the current carbon intensive shipping system to one with a lower climatic impact. Drawing on the multi-level perspective from the socio-technical transitions literature, this paper focuses on two technological developments which could reduce the emissions from shipping – slow steaming and wind propulsion. Outlining the landscape changes which may hinder or support the incorporation of each of these innovations into the broader shipping regime the paper shows how slow steaming has been accommodated within this regime, in response to high oil prices and the economic downturn. In the longer term it concludes that additional policy measures may be required to ensure slow steaming persists should landscape pressures reduce. Oil prices, and the environmental agenda, are driving the development of wind propulsion, but more needs to be done to support those companies which seek to demonstrate and commercialise modern incarnations of the original pioneers of the seas.
