It appeared that an informal grouping on sustainability was beginning to take place and this could be the first step to a more strategic group as appetite for a more senior group develops. In order to do this the LDA worked alongside Innovas and DTZ to define and develop a working definition of the low carbon economy and the number, type and skills levels of low carbon jobs in the London labour market. This Innovas study draws from over 720 sources. It includes activities undertaken by companies across the whole environmental supply chain, from R&D, through manufacturing into distribution, retail, installation and maintenance services.
