We note a change of climate at Z/Yen Group, not just our recent sale of a subsidiary to Aon, but also the increasing emphasis on "climate change". As regular readers know, our interest in environmental matters is long-standing and, at a personal level, well pre-dates our 1994 founding. Nevertheless, it is gratifying to see numerous projects finally underway. The London Accord, our "cash-in, carbon-out" project with BP and the City of London Corporation, among others, holds its pathway conference on 29 and 30 March at Reuters in London. We also made a small contribution to a February 2007 publication, "Clean Capital: Financing Clean Technology Firms In The UK", produced by Forum for the Future, in partnership with the City of London Corporation, DTI, Defra and Gresham College. “Clean Capital” – available at Green Futures Magazine – states that London’s Alternative Investment Market (AIM) is the market of choice for cleantech start-up companies, already listing 61 firms with a combined market capitalisation of over £4 billion.
