By way of example, the Association of British Insurers (ABI 2011), representing the third largest insurance industry in the world (after the USA and Japan) notes that of the GBP 1.6 trillion in assets under management held by its members from their long-term savings products (i.e. pensions, annuities and life-insurance) most is invested in domestic and overseas equity and bonds. Other investment and cash accounts for 7% or around GBP 100 billion. Industry estimates are that up to around GBP 20 billion of this is invested in infrastructure, and it could be estimated that maybe 10%, or around GBP 2 billion is in ‘green’ projects (mostly renewable energy such as wind farms and solar).
