The UK has seen continued development in the green taxes and regulation arena throughout 2011, including the introduction of a Carbon Price Floor and changes to the Carbon Reduction Commitment Energy Efficiency scheme.

Through 2012 the government will be looking to align thinking throughout the Coalition on environmental tax policy, to ensure the proposed changes strike the balance between delivering effective environmental change, raising revenue and the challenges of the current economic situation.
