To ask the Secretary of State for Transport, what estimate has been made of the reduction in shipping emissions by the end of the Parliament.

Answer

Keir Mather

Under the planned scenario presented in the Carbon Budget and Growth Delivery Plan, the greenhouse gas emissions from UK domestic and international shipping are estimated at around 10.4 million tonnes of carbon dioxide equivalent (MtCO2e) in 2029, an estimated reduction of around 4.2 million tonnes of carbon dioxide equivalent (MtCO2e), or 29%, from the 2008 base year of our emissions goals. Our approach to deliver these emission savings are set out in our Maritime Decarbonisation Strategy [2].
