Last week saw three developments – in the UK’s climate change legal framework, and the EU’s Energy Performance of Buildings Directive and Climate Action Regulation – which illustrate how in both the UK and Europe the aspiration to meet net zero emissions by the middle of the century (in line with the Paris Agreement on climate change) is not yet backed up by measures to achieve that goal.

UK sets aim for net zero

The UK’s energy and clean growth minister Claire Perry made a significant and unexpected announcement that she will ask the country’s Committee on Climate Change (CCC) for ideas on how to adopt the goal of the Paris Climate Agreement to limit global warming to below 2°C above pre-industrial levels, with an aspiration to keep it below 1.5°C. This means achieving net zero emissions by 2050.

She made the announcement at a meeting of the Commonwealth Heads of Government last week.

“After the IPCC report later this year, we will be seeking the advice of the UK’s independent advisers, the Committee on Climate Change, on the implications of the Paris Agreement for the UK’s long-term emissions reduction targets,” she said.

The independent CCC exists to set five-year plans for the UK to meet its legally binding target under the Climate Change Act (2008) of reducing carbon emissions by 80per centon 1990 levels by 2050. It then monitors and reports on the UK’s progress.

Perry’s announcement was welcomed by the low carbon industry and campaign groups, but they cautioned that legislation is needed soon.

Dustin Benton, policy director at thinktank Green Alliance, said: “The government has made real progress on some issues, such as diesel cars and offshore wind, but there are glaring holes in areas such as energy efficiency and onshore renewables,” adding waste, housing and transport to the list.

Greenpeace executive director John Sauven said this would mean the end of plans for a new runway at Heathrow.

“No new runway at Heathrow will fit inside our carbon budget. The data show that the challenges posed by emissions from transport – land, sea and air – and our reliance on gas for heating will have to be confronted as a matter of urgency.”

The CCC itself recently challenged the government’s policies, saying they did not go far enough even to meet current targets.

They want to see “urgent action” on the Clean Growth Strategy (published in October 2017), and to see detail on a long list of ideas that have been adopted by the governmentto reduce emissions but which are not accompanied by substance on strategy.

These include: phasing out sales of petrol and diesel cars and vans by 2040, increasing the energy efficiency of homes by 2035 and the energy efficiency standards of new buildings, how to phase out installation of gas and oil, to generate 85per centof the UK’s electricity from low-carbon sources by 2032, and deploying carbon capture and storage technology.

They highlight also a need for new policies to close the remaining “emissions gap” in the fourth and fifth carbon budgets.Even if delivered in full, existing and new policies, including those set out in the Clean Growth Strategy, miss the fourth and fifth carbon budgets by around 10-65 MtCO2e – a significant margin.

The CCC says, “There is a particular risk around meeting the fourth carbon budget which begins in just five years’ time, including completion of Hinkley Point C nuclear power station”. This is looking increasingly unlikely due partly to EDF’s problems on completing a similar reactor at Flamanville.

Energy Performance of Buildings Directive

Meanwhile, on 17 April, the European Parliament approved the Energy Performance of Buildings Directive. This will target the renovation of buildings, and the creation of smarter energy systems for new buildings, acknowledging that around 75per centof buildings in Europe are currently energy inefficient and that buildings are the largest single energy consumer in Europe, using around 40per centof final energy.

The revisions to the previous version of the directive form the first of eight proposed steps towards the EU’s Energy Union ambitions and include advocating the use of smart technologies to introduce automation and control systems, which could ensure buildings operate efficiently; the use of a “smart readiness indicator“, which can measure a building’s capacity to integrate new technologies; support for the introduction of new infrastructure for e-mobility in new buildings; and a path towards zero-emissions buildings by 2050.

There are also mechanisms to create the investment needed to renovate existing buildings to make them more energy efficient: at least 40per centof infrastructure and innovation projects financed by the European Fund for Strategic Investments should contribute to the Commission’s commitments on climate action and energy transition in line with the Paris Agreement. There is also funding under the European Investment Bank’s Smart Finance for Smart Buildings Initiative. This aims to unlock a total of €10 billion (AU$16b) in public and private funds between now and 2020 for energy efficiency projects.

The European Commission vice-president for the Energy Union, MarošŠef?ovi?, said: “As technology has blurred the distinction between sectors, we are also establishing a link between buildings and e-mobility infrastructure, and helping stabilise the electricity grid.”

The Council of Ministers has yet to finalise agreement of the directive before it enters into force. Member states will have to transpose the new elements of the directive into their national laws within 20 months. If the UK eventually Brexits, it will not have to.

The Fifth Estate has already reported here and here on how the directive has been watered down.

New EU Climate Action Regulation

A new European Climate Law is also edging closer. The Climate Action Regulation (CAR) covers almost 60per centof all greenhouse gases and establishes annual carbon budgets between 2021 and 2030 for each EU country, covering sectors like surface transport, buildings, agriculture, small industry and waste, as follows:

How effective it is as will depend on the policies adopted by each member state, which, in the coming months, are supposed to develop national energy and climate plans to show how they expect to meet their commitments under the directive.

The European Council already has an overall GHG reduction target for the EU, of reducing emissions 40per centby 2030 compared to 1990, with a sub-target for sectors not included in the emissions trading system (ETS) of 30per centreduction compared to 2005. The CAR gives each country an individual target to implement that target. France and Germany have by far the highest targets. Eastern European and other less industrialised countries such as Greece and Portugal will be able to continue to increase emissions (for the full list see the table on page 5 of this analysis).

This is not as straightforward as it might seem. The CAR is meant to contain flexibilities to let nations meet targets more cost-effectively, but, according to separate analysis by three think tanks (Sandbag, T&E and Öko Institut), this means it is full of loopholes that allow countries to get out of their commitments, meaning it will only lead to 25-26per centreductions compared to 2005. Furthermore, they say, it does not provide the incentives to put the EU in line to fully decarbonise these sectors by 2050.

In respect of action on reducing emissions, the UK was one of the EU’s high performers. With it out of the Union, the rest will have to try harder to achieve that 40per centtarget. However, T&E says they won’t make it.

“Countries that will not meet their 2020 targets will be rewarded by being allowed to emit even more”.

It cites the example of Ireland, whose emissions since 2011 have steadily increased. Rather than the CAR giving it a baseline starting point for emission reductions of the 2020 target of 20per centrelative to 2005 levels, it is being given a 2018 level, which means, because it is failing to reduce emissions to badly, it has to achieve just fiveper centrelative to 2005 emissions. Austria, Belgium or Finland could also be among the countries that will benefit from this starting point.

The whole effort summons up a picture of a person put on a diet by a doctor eying a cream pie: the head knows it shouldn’t eat it, but the body has to be dragged kicking and screaming away from the table. At least the head has drawn up rules; whether it can implement and enforce them effectively is another matter.
