The Committee on Climate Change (CCC) has issued “unequivocal advice” to the government not to carry forward an emissions surplus from the second carbon budget to subsequent accounting periods. In a letter to energy and clean growth minister Claire Perry, the chair of the climate watchdog, Lord Deben, said rolling over the surplus would make it “more difficult and expensive” for the UK to meet its long-term emissions targets. “The committee’s unequivocal advice is that surplus emissions from the second carbon budget should not be carried forward,” he wrote. “The carbon budgets have been set to meet the 2050 target at lowest cost, and on the basis that there would be no carry forward of surplus emissions from earlier periods.”

Dave Elliott: It’s full steam ahead for renewables in the DNV-GL consultancy’s latest Energy Transitions Outlook. It looks to wind and solar power having a 29% and 40% share, respectively, of total global electricity generation by 2050, with nuclear stalled and energy demand peaking by 2035. That’s despite there being a boom in electric vehicle (EV) use – renewables can support that, with electrification carrying all before it. “Electrification and its inherent efficiency will contribute to humanity’s energy demand declining from the mid-2030s onwards,” the report says. “Global expenditure on energy, as a percentage of GDP, will fall 44% by 2050.” However, DNV-GL says it won’t be automatic: “high fractions of solar and wind will create a need for increased use of market mechanisms and changes to the electricity market fundamentals”. So the consultancy wants policy makers to intervene and put in place “measures to incentivize a demand shift towards clean energy, to stimulate innovation in new efficient and clean technologies”. Otherwise we won’t hit the Paris climate targets. A shift to flexible demand management is certainly now high on the agenda. That’s unsurprising, since it may turn out to be the cheapest way to respond to variable renewable supply. For example, introducing “time of use” electricity tariffs can shift demand away from times when renewable inputs are low. And it involves no extra capital cost, unlike installing storage capacity or using back-up supply capacity. What’s more, the consumer market system can hopefully be improved – there is certainly a need for some rationalization of the existing, sometimes perverse, pricing system for heat supply.

The UK’s housing emissions are “off track” to meet the country’s climate targets, the Committee on Climate Change (CCC) says in a new report. These should have fallen to 13% below 1990 levels by 2017, the government’s official climate adviser says, yet the actual reduction was just 9%. The country’s housing stock is also far from ready to deal with the effects of rising temperatures, says the CCC, including flooding, overheating and water scarcity. The “shocking fact” is that most of the UK’s near-30m homes are “not in a condition to keep us comfortable and safe and productive in the changing climate”, Baroness Brown, chair of the CCC’s adaptation committee, tells Carbon Brief.
