Driving Emission Out of Shipping - A race against time
Magnus Gustafsson, Partner at PBI
Green-house-gas (GHG) emissions from shipping have until recently received little scrutiny or regulatory attention. They were left out of the Paris agreement on climate change, which sets out a global action plan to keep global warming well below 2°C, requiring reduction commitments by individual nations. Because overall global temperature rise depends on cumulative global CO2 emissions, the Paris temperature range can be translated into a 600 Gt budget of CO2 emissions that are still permissible, but requires global and drastic cut-downs by all sectors, including all actors within the shipping sector.
Although shipping is the most energy-efficient transport mode to move large volumes of cargo, in a business as usual scenario with an annual estimated growth rate of three (3) percentage and no actions taken to cut CO2 -emissions, an increase by nearly a quarter (23 % equalling 1090 tonnes is projected by 2035). Reducing emissions on a global scale presents significant challenges to all industry sectors, including sea freight. Figure 1 shows that the sooner the process of reducing emissions is commenced, the more time there will be to switch to low-emission operations in a sustainable manner. If the process for reducing emissions is not commenced within the next few years, the world faces significant warming and drastic measures.
