DEFRA has now published details of the UK's emissions of carbon dioxide for 2005 and 2006. Although this is not reporting in real time, it does provide an insight into the way individual sectors managed their quotas during the first two years' operation of the EU Emissions Trading Scheme. Details for 2005 are presented in a series of pdf files that can be accessed here. Summary sheet 17 includes carbon prices and trading volumes from the start of the scheme to June 2006.
It may be noted that the power generation sector failed to meet its allocations by 36.5% in 2005 and a further 46% in 2006. As a consequence, generators had to purchase additional allowances, but quite easily passed these costs on to the UK consumer. Because allocations were relatively generous, other industries appear to have met their carbon dioxide quotas with ease.
