Europe has to step up its effort to combat climate change and wake up to the urgency of the situation, climate change expert Lord Stern said before crunch UN talks in Paris later this month.
Europeans need to end subsidies for fossil fuels, multiply energy efficiency efforts, improve mass public transport systems and accelerate the roll-out of electric cars to live up to their commitments, Stern said in an interview.
Decisions taken at the Paris summit, which is to open on Nov. 30, will shape the world’s carbon course for the next two decades, which in turn will determine whether there is a chance of avoiding a global temperature rise of more than 2oC, considered to be the threshold for dangerous warming.
“In human history, it’s a one-off and what we map out in the next two decades will be absolutely critical,” he said. “Whether we can live in our cities — breathe in them, move in them — all of this will be defined by the decisions we take.”
“I don’t think the criticalness of these 20 years is sufficiently understood,” he said.
Stern’s word were echoed by a high-ranking UN science adviser, Jim Skea, who agreed that the EU needed to go beyond existing pledges of cutting greenhouse gas emissions by 40 percent by 2030.
Skea, from Imperial College London, said Europe needs to raise that pledge to at least 45 percent, and ideally to 50 percent.
“If we were in the upper end of the 40s it would be perhaps the lowest-cost way of getting to the ambitious improvement in the long term,” he said.
His claim will be controversial among governments and some powerful industries, who are concerned that they are already at a disadvantage because restrictions on pollution are so much tougher in Europe than in other parts of the world. The UK steel industry is among the claimed casualties.
EMISSIONS PLANS
More than 140 countries have already submitted plans for cutting their emissions before the talks in Paris. On Friday last week, the UN Environment Program (UNEP) said the offers fell significantly short of what was needed for a 66 percent chance of stopping the average temperature rising by 2oC or more.
The EU’s pledge is among the most ambitious, though analysis of the policies of the 28 member states suggests they are not yet on track to fulfil it.
“They [the EU] were leaders, and they vacillated,” said Stern, who is now chairman of the Grantham Research Institute on Climate Change and the Environment at the London School of Economics, and a crossbench peer. “They have to do better than that [40 percent], but I think they are rekindling.”
For the EU to increase targets and meet greater emissions cuts, governments will need to resist political pressure to prop up their coal industries, and the European Commission must reduce allowances in the emissions trading system even more quickly than planned, said Skea, who was appointed co-chair of the working group on mitigation, which compiles five-yearly reports for the UN’s Intergovernmental Panel on Climate Change (IPCC).
Both measures are expected to meet opposition, including in Germany and Poland.
The UNEP projection said country pledges so far would be likely to generate emissions equivalent to 54 gigatonnes of carbon dioxide in 2030, higher than current emissions, but 11 gigatonnes less than if no action were taken.
To meet the ambition of a “likely” chance of avoiding more than 2oC warming, the figure needs to be reduced to 42 gigatonnes by 2030, and a carbon-free world economy in the second half of this century, it said.
PLEDGES
The calculation does not take account of thousands of pledges being made by companies, industry groups, cities and regions or provinces, many of which are more ambitious than the nations they operate in.
In recognition of how important those further cuts could be, organizers in France are hosting the once-fringe players in prestigious central locations. Organizers are even hopeful that the planned “Paris outcome” statement by French Minister of Foreign Affairs Laurent Fabius will include these promises.
“The cities and businesses are credible,” said Stern, author of a seminal report arguing that catastrophic climate change would cost the world’s economies more than trying to stop it. “If you get this right, it could be so attractive; if you get it wrong, it will be so difficult.”
Stern warned Europe could not be complacent about the impacts of climate change.
“Europe is warming faster than many other parts of the world,” the economist said.
“Some extreme weather events have increased, with southern and central Europe seeing more frequent heat waves, forest fires and droughts. Many parts of southern Europe could face desertification if global average temperature rises by significantly more than 2oC,” he said.
Heavier precipitation and flooding is projected in northern and northeastern Europe, with a heightened risk of coastal flooding and erosion.
“The European land temperature over the past decade has been on average 1.3oC higher than in the preindustrial era, compared with a global average rise of about 0.8oC. Impacts vary across the European Union, but all member states are exposed to climate change. The Mediterranean basin, mountain areas, densely populated floodplains, coastal zones, outermost regions and the Arctic are particularly vulnerable to climate change impacts,” Sten said.
The conflict in the Middle East has been disrupting financial markets, raising concerns about rising inflationary pressures and global economic growth. One market that some investors are particularly worried about has not been heavily covered in the news: the private credit market. Even before the joint US-Israeli attacks on Iran on Feb. 28, global capital markets had faced growing structural pressure — the deteriorating funding conditions in the private credit market. The private credit market is where companies borrow funds directly from nonbank financial institutions such as asset management companies, insurance companies and private lending platforms. Its popularity has risen since
The Donald Trump administration’s approach to China broadly, and to cross-Strait relations in particular, remains a conundrum. The 2025 US National Security Strategy prioritized the defense of Taiwan in a way that surprised some observers of the Trump administration: “Deterring a conflict over Taiwan, ideally by preserving military overmatch, is a priority.” Two months later, Taiwan went entirely unmentioned in the US National Defense Strategy, as did military overmatch vis-a-vis China, giving renewed cause for concern. How to interpret these varying statements remains an open question. In both documents, the Indo-Pacific is listed as a second priority behind homeland defense and
Every analyst watching Iran’s succession crisis is asking who would replace supreme leader Ayatollah Ali Khamenei. Yet, the real question is whether China has learned enough from the Persian Gulf to survive a war over Taiwan. Beijing purchases roughly 90 percent of Iran’s exported crude — some 1.61 million barrels per day last year — and holds a US$400 billion, 25-year cooperation agreement binding it to Tehran’s stability. However, this is not simply the story of a patron protecting an investment. China has spent years engineering a sanctions-evasion architecture that was never really about Iran — it was about Taiwan. The
After “Operation Absolute Resolve” to capture former Venezuelan president Nicolas Maduro, the US joined Israel on Saturday last week in launching “Operation Epic Fury” to remove Iranian supreme leader Ayatollah Ali Khamenei and his theocratic regime leadership team. The two blitzes are widely believed to be a prelude to US President Donald Trump changing the geopolitical landscape in the Indo-Pacific region, targeting China’s rise. In the National Security Strategic report released in December last year, the Trump administration made it clear that the US would focus on “restoring American pre-eminence in the Western hemisphere,” and “competing with China economically and militarily
