Introduction and background

1.1    The Greater London Authority Act 1999 (the “Act”) requires the Mayor to produce a London Environment Strategy (LES) which must contain the following: biodiversity, municipal waste management, climate change mitigation and energy, adaptation to climate change, air quality and ambient noise.

1.2    In DD2048 expenditure of up to £70,000 to undertake the IIA of the London Environment Strategy was agreed.

1.3    Following the appointment of Jacobs and executing the contract, the GLA required additional work, i.e. the Variations, to complete the IIA; these are detailed in Section 2 below. The Variations will be carried out under and in accordance with the terms of the existing call-off contract between GLA and Jacobs.

Objectives and expected outcomes

2.1    The Variations from the original contract that are required to be completed by Jacobs are:
•    Variation 1 (approved) - Undertaking a full review of the LES IIA Scoping Report to check for consistency and compliance with the SEA directive. This review will include a review of the framework section and associated questions [£1,165]
•    Variation 2 (approved) - Undertaking a high-level economic consideration of each LES option against the relevant IIA objectives included in the scoping report. The output of this work will be a high-level consideration against the relevant objectives and will include recommendations for methodologies to answer the guide questions during subsequent completion of the IIA [£8,289]. 
•    Variation 3 (to be approved) - Undertaking a further review of the LES by Jacobs to ensure the IIA report is in line with the draft LES to be published for consultation [£6,945]

4.2     The IIA is a requirement for the preparation of the Mayor’s LES.
