Executive summary

The GLA uses a model to understand and forecast London waste arisings and waste management methods. This information is used to 1) inform the Mayor’s waste policy and programmes and 2) support the waste infrastructure investment need for the Infrastructure Investment Plan 2050.

The current model uses some data now 10 years old, which has never been independently reviewed and is considered out of date. It is necessary to review and update the GLA’s waste model using new waste tonnage and cost data with new London population and economic activity forecasts. This will ensure the GLA model is fit for purpose to credibly inform the Mayor’s waste policies and programmes.

In order to review and update the model, there will be a requirement to procure consultancy services up to a maximum expenditure of £15k from the Environment Team 2013/14 budget, (already approved in principle by the Environment Team Management Group). It is proposed to obtain the services of SLR Consulting who completed related modelling work for the Further Alterations to the London Plan approved via ADD100 (attached as Appendix 1). There are financial saving and consistency benefits to be gained from this approach, which requires exemption from the GLA’s Contract and Funding code namely to seek three quotes. Seeking three quotes is unlikely to deliver value for money due to the resource requirement to prepare the necessary waste data and methodology already developed by SLR.
