This report has been prepared by Ricardo for Schneider Electric to estimate the 2016 emissions to air released from the operation of auxiliary engines on ships whilst at berth in UK ports. This is in the context of Schneider Electric considering the local benefits to be gained from the potential emissions to be avoided by supplying the ship with shoreside electricity that is generated from 100% renewable sources. The work has been carried out in March 2018.

This work estimates an annual total of emissions released by vessels’ auxiliary engines at berth in ports around the UK. This report does not assess the resulting impacts on local air quality, i.e. the contribution to ambient concentrations of pollution after dispersal of the emitted pollutants, which would need to consider flue gas characteristics, meteorological conditions, and other local emission sources.
