[holding answer 23 November 2009]: Specific estimates of black carbon emission have not been made in support of the development of the Renewable Energy Strategy.
The emissions of black carbon for each unit of heat delivered are likely to decrease in future as a result of measures announced in the Government's Renewable Energy Strategy. Efficient modern biomass appliances have advanced combustion control systems. When maintained adequately and fuelled correctly, the particles emitted under normal operating conditions are primarily composed of the inorganic salts naturally present in the wood, not carbonaceous material.
According to recent research published by the Carbon Trust building on research by New Energy Finance, total UK venture capital clean energy1 investment (including renewables) between 2003 and 2008 was:

€ million 2003 131 2004 123 2005 182 2006 167 2007 269 2008 83
The purpose of the up to £18 million additional venture capital investment available via the Carbon Trust is to meet the current market failure in the provision of private sector venture capital investment for early stage low carbon companies.
Since the Carbon Trust was set up, it has provided funding to 17 green start-up energy companies investing over £13.5m. This funding has also helped these businesses to leverage over £117 million of private sector investment.
No investments have yet been made from the £18 million additional funding but four companies are in due diligence and a further 10 are under active consideration.
