Further to your approval of plans for a new cruise liner terminal at Enderby Wharf in Greenwich, are you satisfied that the independent air quality consultancy you instructed to study the impact of emissions arising from this development correctly identified the the typical electrical load, NOX emission rate, and 'hotelling' requirement of a cruise vessel in berth at this terminal?

The role of the GLA in reviewing planning applications is to assess the compliance or otherwise with relevant London Plan policies, not to duplicate the decision-making of the local planning authority. Amec Foster Wheeler (AMEC), as contractors to GLA, independently reviews some air quality reports on behalf of the GLA to verify their findings and provide advice to officers where necessary. In this case, the findings of AMEC's review were used to inform the overall assessment of the planning merits of the proposals and are summarised in the air quality section of the Mayor's stage two planning report (ref:D&P/2515b/02).

The electrical load used within the Council's own assessment was based on a typical medium sized cruise ship likely to berth at the terminal. AMEC's review of this assessment identified these figures as being compatible with a 3.5MW Tier II engine running at 1,050 rpm and the emission rates reflected Defra's emission factors for a ship in a SECA (Sulphur Emissions Control Area) in 2015. On review, the content of the report was considered acceptable.

As set out in the planning report, the assessment (as verified by AMEC) did find that in the worst case, that is if all the least favourable meteorological conditions coincided with the time spent by ships at berth, the development may give rise to small exceedances of the NO2 short term AQO. This is why over £400,000 has been secured towards local mitigation in accordance with Greenwich Council's Air Quality Action Plan, in addition to securing a low emissions transport scheme with the aim of minimising emissions from construction and operational traffic.

GLA officers are seeking further discussions with the Council's Environmental Health team with regards to the expenditure of the secured funds on the most effective mitigation measures possible.
