Germany’s €100bn climate funding

BILLIONS IN FUNDING: Germany’s parliament on Tuesday voted to create a €500bn defence and infrastructure fund and relax “constitutionally-protected debt rules”, the Guardian reported, with “the last-minute backing of the Greens” in return for “guarantees that €100bn of the funds destined for infrastructure would be allocated for climate and economic transformation investments”. The deal came following “clumsy” initial negotiations from Germany’s chancellor-in-waiting, Friedrich Merz, Bloomberg said. It reported that the Greens “finally came around” after Merz’s negotiators “conceded to their key demands”, which also included adding Germany’s 2045 climate-neutrality target into the constitution.

TAKING CLIMATE ‘SERIOUSLY’: The Greens said in a statement on social media that the agreement “finally takes the challenges of the future seriously”, according to the New York Times. Paula Piechotta, a member of the Greens in the German Bundestag, told the German newspaper Tagesspiegel that the deal was a “great success for democracy in our country, for sustainability and intergenerational justice”. The newspaper added that the far-right Alternative for Germany (AfD) and the Left party, “unsurprisingly”, criticised the agreement.

UK opposition breaks cross-party climate consensus

BREAKING AWAY: In a speech, Kemi Badenoch, leader of the UK opposition Conservative party, said it was “impossible” for the UK to meet its net-zero target by 2050, marking a “sharp break from years of political consensus”, BBC News reported. She did not offer an alternative target for the goal, the broadcaster said, quoting her telling reporters that if the Conservatives “do find a target is necessary, then yes we will have one”. Badenoch “failed to cite any evidence in support” of her arguments, according to a factcheck published by Carbon Brief, which concluded that much of the existing evidence “contradicts” her claims.

TORY BACKLASH: In response, Conservative former prime minister Theresa May, who was responsible for passing the 2050 target into law, warned the move “will hurt future generations and cost Britons”, the Times reported. The Confederation of British Industry (CBI) also criticised the speech, warning that “now is not the time to step back from the opportunities of the green economy”, according to the i newspaper. In the Daily Telegraph, Ambrose Evans-Pritchard said Badenoch’s “rant comes close to political tragedy”.

Around the world

• CARNEY CUTS: New Canadian prime minister Mark Carney removed the country’s “consumer carbon tax”, CBC News reported, adding that the policy had been a “potent point of attack” for his political opponents.
• GREENPEACE BILL: Greenpeace has been ordered to pay $660m in damages over its protests against the Dakota Access pipeline in 2016, which could “bankrupt its US operations” if upheld, the Financial Times said.
• UK-CHINA FORUM: The UK and China agreed to establish an “annual climate dialogue”, with the first meeting to be held in London later this year, the Times reported. 
• CHEQUES AND BALANCES: A US judge has “temporarily barred” attempts by the Trump administration to recoup at least $14bn in “grants issued by the Biden administration for climate and clean-energy projects”, the Washington Post said.
• EXTREME HEAT: “Severe heatwave conditions” have begun affecting several areas across India “unusually early in the season”, the Hindustan Times reported.
• SOUTH AFRICAN SUPPORT: The EU will fill a “$1bn hole” in South African’s “just energy transition partnership” left by the US, the Financial Times reported. The US is also “stalling” $2.6bn of climate finance for South Africa, Bloomberg said.

152

The number of “unprecedented” extreme weather events that occurred in 2024, according to the World Meteorological Organization’s State of the Climate 2024 report. Heatwaves were the most common type of unprecedented events – defined as events “worse than any ever recorded in the region” – followed by “rain or wet spells” and floods.

Latest climate research

• New research in Climate and Development explored how environmental justice featured in the climate action plans of rust-belt cities in the US, finding that few “provided enough details” to determine if it was a priority.
• A new Science Advances study identified “increasing storminess” in the south-western Caribbean, which was attributed to “industrial-age warming”.
• Marine heatwaves are now 5.1 times more frequent and 4.7 times more intense since records began, new research in Communications Earth & Environment found.

Captured

The UK’s high electricity prices are primarily driven by gas prices, according to an analysis published by Carbon Brief, with the UK typically seeing gas set electricity prices 98% of the time – compared to an average in the EU of 40%.

Chatham House talks climate and resilience

Carbon Brief outlines key takeaways from Chatham House’s climate and energy summit.

Chatham House, the UK’s leading international affairs thinktank, held its annual summit on climate and energy on 18-19 March. This year’s theme was: “Securing a resilient future.”

Carbon Brief attended the conference, where speakers including COP30 CEO Ana Toni, UK climate envoy Rachel Kyte and Moroccan minister for energy transition and sustainable development Leila Benali shared their thoughts on encouraging and enacting climate action.

Climate backlash

A sense of urgency permeated discussions at the summit, underpinned by concerns over growing anti-climate narratives.

Toni argued climate scepticism proves climate action is on the right track.

She said: “First people ignore you, then they laugh at you, then they fight you – and this is where we are – then we win.”

Other speakers said that increasing support for climate action by building new norms and creating overlapping interests could also be effective strategies.

Former US climate envoy Todd Stern pointed to increasing adoption of electric vehicles, while ClientEarth CEO Laura Clarke raised the example of community-owned renewable power.

Fretting over finance

Clean Earth Gambia founder Fatou Jeng warned that climate finance, as ever likely to be an important issue at COP30, has “not progressed much”.

“Blended finance” – using public money to leverage private funds – was heavily criticised in several panels. Ben Parsons, a partner at consultancy firm Oaklin, noted that only 72 such deals were agreed in 2024.

Speakers agreed that innovative mechanisms to derisk climate finance were needed, with Morocco’s Benali critiquing “exclusive” and inflexible private financing options.

Ndongo Samba Sylla, head of research and policy at International Development Economics Associates, argued that using local currencies would significantly boost climate finance.

Resilience through renewables

A key benefit of the UK’s “climate leadership”, Kyte argued, is that the energy transition will “make British people more secure”.

Parsons said the argument – recently deployed by Conservative leader Badenoch – that the energy transition replaced reliance on Russian fossil fuels with reliance on Chinese technology was incorrect.

“Fossil fuels are fuel – they require constant replenishment. Renewables are infrastructure,” he said, adding that arguably the UK should be accelerating its deployment of clean-energy technology.

On cybersecurity challenges in renewable power systems, Alex Schoch, vice president and group director of flexibility and electrification at Octopus Energy, argued that the key issue is how renewable energy “hardware” is managed, rather than where it is sourced from.

Parsons agreed, noting that the UK’s current power system has “plenty of cybersecurity vulnerabilities in it today”.

He said: “We have to make sure we’re putting [cybersecurity strategies] in place…But I don’t think that goes hand in hand with thinking we should avoid buying renewables from certain parts of the world.”

In a session on energy security in war-time Ukraine, held under the Chatham House rule, participants noted that the country was a case study for the importance of energy security.

Speakers said that since Russia’s invasion of Ukraine, attacks on thermal power plants have seen growing use of low-carbon energy – particularly distributed solar.

‘CONFLICT BLINDSPOT’: A new report by ODI found that “less than 10% of international climate finance” in 2022 went to fragile and conflict-affected countries.

METHANE INACTION: Leading supermarkets in the global north are “failing to address the methane pollution in their supply chains”, according to a study covered by Desmog.
