New publication: Exploring the scope for complementary sub-global policy to mitigate CO2 from shipping
A new paper published in Energy Policy by researchers at Tyndall Manchester and the Sustainable Consumption Institute highlights the inadequate progress made to date by the shipping sector in developing policies to cut in real terms the CO2 produced by shipping goods.
Two prominent discussions hinder progress in rolling out measures to significantly cut emissions: firstly, the conflict between the International Maritime Organisation's principal of applying shipping standards and policies to all ships, with the United Nations Framework Climate Change Convention's 'Common but Differentiated Responsibility' that aims to fairly distribute efforts to cut emissions; secondly, the debate regarding how, if desired, nations could reasonably apportion out the emissions from the global shipping sector to individual nations or regions in order to develop policy measures.
The paper illustrates that a rapid step-change is needed in policymaking to ensure shipping, like other sectors, fully decarbonises by or soon after 2050 to avoid a global temperature rise of 2C. It goes on to suggest that discussions around apportionment are hindering the development of sub-global policies, and that policies aimed at aspects of the shipping system that can be influenced either by nations or organisations with multi-national supply chains, should be explored as a matter of urgency.
