The mayors of ten major European cities –including Paris, London, Milan and Barcelona – have issued a joint call for the EU to achieve net-zero carbon emissions by 2050, in line with the Paris Agreement.
The joint call by the ten mayors coincides with the launch of a public consultation this week (10-11 July) by the European Commission to update the EU’s low-carbon energy roadmap for 2050.
“We urge the European Commission to set the 1.5°C and net-zero emissions goals of the Paris Agreement as objectives of this strategy to be achieved by 2050,” the mayors write in an open letter to the EU executive, dated 9 July.
To reach that goal, emissions in Europe “must peak by 2020” and decrease until reaching carbon neutrality by mid-century, they write.
The group of ten European mayors are part of a wider coalition of 9,000 cities worldwide, which have committed to reduce their greenhouse gas emissions by 40% by 2030 and to design adaptation strategies to address the impacts of climate change – such as heatwaves, and floods.
“But considering the worrying increase of EU emissions in 2017, we recently decided to step up our ambition, and have pledged to become emissions neutral by 2050,” the mayors write in the letter.
“We are working on defining new sectoral targets for 2030, towards zero-emission transport, net-zero buildings, 100% renewable energy, and zero waste,” they add.
Signatories of the open letter include the mayors of major European cities such as Paris, Bonn, Stockholm, Copenhagen, Milan, London and Barcelona. Smaller cities like Arendal (Norway), Heidelberg (Germany) and Turku (Finland), also signed up.
Their joint call comes only weeks after EU legislators agreed new 2030 objectives for energy efficiency and renewables, which effectively raised the EU’s greenhouse gas emissions pledge made as part of the Paris Agreement.
Current objective “out of date”
The EU’s existing 2050 low-carbon economy roadmap was published in 2011, before the bloc signed up to the Paris Agreement, which commits its signatories to keep global warming “well below 2°C” and aiming for “no more than 1.5°C”.
The European Commission is now expected to present an updated version in November, just ahead of the United Nation’s annual climate conference, which this year takes place in Katowice, Poland.
“The economics of climate solutions have transformed” since 2011, said Jonathan Gaventa, Director of E3G, a think tank. “Technologies such as solar PV and onshore wind are now already cheaper than the Commission assumed they would be in 2050,” he remarked, saying the EU’s objective of an 80% emissions cut by 2050 “is now painfully out of date”.
Momentum is growing behind the objective of reaching net-zero emissions in 2050. In June, a coalition of 14 EU member states called upon the Commission to ensure that the new mid-century strategy contains both a pathway to reduce emissions towards net-zero by 2050, and a pathway to limit temperature rises to 1.5°C.
“This new strategy should be based on the latest available science, especially the next special IPCC report on 1.5°C,” which is expected in the Autumn, ahead of the COP24 in Poland, the ‘Green Growth Group’ of EU countries said in a joint statement.
A few days earlier, France and Germany called on the Commission to develop an EU strategy 2050 that aims “for the long-term transformation towards carbon neutrality,” arguing this was “not only a necessity, but also an economic opportunity”.
The net-zero emissions goal is also supported by the recently agreed energy union governance regulation, which calls for Europe to achieve carbon neutrality “as early as possible”.
The group of ten European mayors said they were ready to contribute and take their “fair share” of responsibility.
“Cities in Europe are big greenhouse gas emitters, and our residents are already affected by the impacts of climate change, including floods in Paris, London or Copenhagen, extreme weather events in Oslo and Stockholm and heat waves in Milan and Barcelona,” the signatories argue.
“We hope this will inspire you to maintain your ambition and give you confidence that emissions-neutrality by mid-century is achievable, not only necessary and desirable.”
