Carbon Brief have published the diagram above, which shows how the Carbon Price Floor, implemented in the UK from March 2013, is expected to provide an incentive to shift to a low-carbon primary energy industry. I think this is a great idea, as the effective price of carbon through the EU ETS has made Europe a laughing stock over the last couple of years when it comes to talking about effective actions for creating a low carbon economy and tackling climate change. The floor price is likely to lead to an effective price of carbon of £30 per tonne by 2020, £70 per tonne by 2030. Now, that's more like it! Here's a link to the original article. Apparently, the consumer group "Which" suggests scrapping the floor price, on the grounds that the measure is too variable in the short-term to incentivise shifts in investment patterns. However, I think it's exactly the sort of measure we need to be in place to overcome the many barriers to creating a low carbon economy. If' like Which, people think it is too variable, then the answer is to strengthen the measure, not scrap it as Which suggests.
Carbon Brief have also published in this linked article an excellent infographic (below) which sets out the expected net reduction in average household energy bills in 2020 caused by current policies, compared with the same future without those policies being in place. This is an effective counter to the often ill-informed "this will increase bills" objection to moving to a low carbon economy.
