Decarbonising Maritime Transport Pathways to Zero-Carbon Shipping by 2035
(International Transport Forum) … This report examines what is needed to decarbonise international shipping by 2035. Zero carbon emissions from shipping within this timeframe is one of the proposed levels of ambition in the context of the International Maritime Organization’s “Initial GHG Strategy”, due to be agreed in 2018. Using the ITF International Freight Model, the report provides an updated baseline scenario for the development of emissions to 2035 and gives an overview of measures that can effectively reduce shipping emissions. Using different combinations of these measures, it charts possible decarbonisation pathways and reviews the conditions for implementation. The report concludes with recommendations on policies to incentivise decarbonisation.
What we found
Maximum deployment of currently known technologies could make it possible to reach almost complete decarbonisation of maritime shipping by 2035. The four potential decarbonisation pathways for shipping identified in this report would result in a CO2 emission reduction between 82% and 95% of the currently projected 2035 level. This reduction equals the annual emissions of approximately 185 coal-fired power plants. Remaining CO2 emissions would be between 44 and 156 million tonnes in 2035.
Alternative fuels and renewable energy can deliver much of required reductions. Advanced biofuels are already available in limited quantities. Gradually, they should be complemented by other natural or
synthetic fuels such as methanol, ammonia and hydrogen.
A smart phasing-in of carbon pricing for shipping could facilitate the implementation of these measures. READ MORE
