Proceeds of the sale are expected to be ploughed back as investments into carbon capture and storage demonstration projects as well as innovative renewable energy technologies.

The bank sold 200m allowances on behalf of the European Commission since the commencement of sale process in December 2011.

Details of the funds raised from the sale will be outlined later in October 2012.

Under the NER300 initiative, 300 million EU allowances were envisaged to be sold that offer rights to emit one tonne of carbon dioxide – from the New Entrants Reserve of the European Emissions Trading Scheme.

While the sale of the first tranche of allowances, totaling 200m, has been completed in the stipulated timeframe, the second tranche of 100m allowances are expected to be sold by April 2013.
