New fuels and accompanying hikes in ticket prices will be essential to clean up air travel and avoid the worst effects of climate change, according to a new report.
Aviation is responsible for 5 per cent of global warming, and it is on track to power through a quarter of the planet’s annual carbon budget by 2050.
Despite some fledgling efforts to develop electric aircraft for short-haul flights, air travel is proving one of the most difficult sectors to decarbonise.In its analysis, European green transport group Transport and Environment (T&E) found that replacing fossil fuels in planes with “electrofuels” is the “only technically viable solution that would allow aviation to exist in a world that avoids catastrophic climate change”.
This will present a challenge to consumers as well as the industry, as the expense of these fuels means the cost of a plane ticket is projected to rise 58 per cent if they replace kerosene in all aircraft.
“The good news is that radically cleaner aviation is possible even with today’s technology,” said Andrew Murphy, aviation manager at T&E.
“Getting to zero starts with properly pricing flying and progressively increasing the use of sustainable synthetic fuels.
“There is a cost to this, but in light of how cheap subsidised air travel has become, and the incalculable cost of runaway climate change, it’s a price worth paying.”

Growth in Japan’s solar power sector is predicted to slow over the coming decade, according to a new analysis from the Fitch Group, but not before the industry adds 17 gigawatts (GW) worth of new solar capacity between the end of 2017 and the end of 2020.
Urgent changes needed to cut risk of extreme heat, drought, floods and poverty, says IPCCThe world’s leading climate scientists have warned there is only a dozen years for global warming to be kept to a maximum of 1.5C, beyond which even half a degree will significantly worsen the risks of drought, floods, extreme heat and poverty for hundreds of millions of people.
We’re getting there, aren’t we? We’re making the transition towards an all-electric future. We can now leave fossil fuels in the ground and thwart climate breakdown. Or so you might imagine, if you follow the technology news.
So how come oil production, for the first time in history, is about to hit 100m barrels a day? How come the oil industry expects demand to climb until the 2030s? How is it that in Germany, whose energy transition (Energiewende) was supposed to be a model for the world, protesters are being beaten up by police as they try to defend the 12,000-year-old Hambacher forest from an opencast mine extracting lignite – the dirtiest form of coal? Why have investments in Canadian tar sands – the dirtiest source of oil – doubled in a year?
The answer is, growth. There may be more electric vehicles on the world’s roads, but there are also more internal combustion engines. There be more bicycles, but there are also more planes. It doesn’t matter how many good things we do: preventing climate breakdown means ceasing to do bad things. Given that economic growth, in nations that are already rich enough to meet the needs of all, requires an increase in pointless consumption, it is hard to see how it can ever be decoupled from the assault on the living planet.

Offshore wind turbine giant MHI Vestas unveiled on Tuesday the world’s first commercially-available 10 megawatt (MW), marking the first time a “commercially-available” wind turbine has broken the double-digit barrier.
The offshore wind turbine capacity arms race has been driven into overdrive of late, with MHI Vestas breaking its own records, one after another, while GE Renewable Energy sits on the sidelines, safe in the knowledge that, when its 12 MW Haliade-X is installed in demonstration form sometime next year, it will have the world’s largest feet-wet offshore wind turbine.
MHI Vestas has been leading the way through 2018, however. The world’s most powerful currently operational wind turbines are the 8.8 MW v164 turbines installed at the European Offshore Wind Deployment Centre (EOWDC) in Aberdeen, Scotland, which was officially opened earlier this month. MHI Vestas has also been the owner of the world’s most powerful commercially available wind turbine thanks to its V164-9.5 MW turbines that passed their final certifications in June and have already been ordered and are expected to be installed by the end of 2019.
Companies hoping to build new windfarms, solar plants and tidal lagoons, have been dealt a blow after the government said there would be no new subsidies for clean power projects until 2025 at the earliest.
The Treasury said it had taken the decision to “protect” consumers, because households and businesses were facing an annual cost of about £9bn on their energy bills to pay for wind, solar and nuclear subsidies to which it had already committed.
The revelation that there will be no more money for projects before 2025 could dash hopes for pioneering projects such as the proposed £1.3bn tidal lagoon in Swansea, which has a mooted launch date of 2022.
In a Treasury document on carbon levies published on Wednesday, officials said: “On the basis of the current forecast, there will be no new low-carbon electricity levies until 2025.
Environmental groups criticised the Treasury move. The WWF said it was a huge disappointment, while Greenpeace claimed Wednesday’s budget was one of the least green ever.
Business groups also reacted with dismay. The pro-environment Aldersgate Group, whose members include BT, Ikea and Marks & Spencer, said the lack of clarity on low-carbon power investments was disappointing.
James Court, head of policy at the Renewable Energy Association, said: “The UK government seem to be turning their back on renewables by announcing no new support for projects post-2020 and a freeze on carbon taxes.”
Famine, economic collapse, a sun that cooks us: What climate change could wreak — sooner than you think.
It is, I promise, worse than you think. If your anxiety about global warming is dominated by fears of sea-level rise, you are barely scratching the surface of what terrors are possible, even within the lifetime of a teenager today. And yet the swelling seas — and the cities they will drown — have so dominated the picture of global warming, and so overwhelmed our capacity for climate panic, that they have occluded our perception of other threats, many much closer at hand. Rising oceans are bad, in fact very bad; but fleeing the coastline will not be enough.
Indeed, absent a significant adjustment to how billions of humans conduct their lives, parts of the Earth will likely become close to uninhabitable, and other parts horrifically inhospitable, as soon as the end of this century.
Christiana Figueres and colleagues set out a six-point plan for turning the tide of the world’s carbon dioxide by 2020.
In the past three years, global emissions of carbon dioxide from the burning of fossil fuels have levelled after rising for decades. This is a sign that policies and investments in climate mitigation are starting to pay off. The United States, China and other nations are replacing coal with natural gas and boosting renewable energy sources. There is almost unanimous international agreement that the risks of abandoning the planet to climate change are too great to ignore.
The French and the Chinese may be celebrating the UK's decision to press ahead with the Hinkley C 'nuclear white elephant', writes Oliver Tickell. But the deal is a disaster for the UK, committing us to overpriced power for decades to come, and to a dirty, dangerous, insecure dead end technology. Just one silver lining: major economic, legal and technical hurdles mean it still may never be built.
'Planning the appropriate renewable energy (RE) installation rate should balance two partially contradictory objectives: substituting fossil fuels fast enough to stave-off the worst consequences of climate change while maintaining a sufficient net energy flow to support the world’s economy. The upfront energy invested in constructing a RE infrastructure subtracts from the net energy available for societal energy needs, a fact typically neglected in energy projections. Modeling feasible energy transition pathways to provide different net energy levels we find that they are critically dependent on the fossil fuel emissions cap and phase-out profile and on the characteristic energy return on energy invested of the RE technologies. The easiest pathway requires installation of RE plants to accelerate from 0.12 TW p yr –1 in 2013 to peak between 7.3 and 11.6 TW p yr –1 in the late 2030s, for an early or a late fossil-fuel phase-out respectively, in order for emissions to stay within the recommended CO 2 budget’.
So the early fossil-fuel phase-out requires the installation of RE plants to accelerate by 7.3/0.12 = 61-fold and the late phase-out by 11.6/0.12 = 97-fold. Further delay would mean that there is no solution.
Four of Britain's major unions are big supporters of nuclear power, writes Ian Fairlie - all because of the jobs. Now Labour's shadow energy minister has joined them in backing Hinkley C - even though renewable energy is a far better job-creator than nuclear, and already employs three times more people.
“Overall we see a great future for offshore wind in the UK for the right type of projects,” a DONG Energy spokesperson told Renewable Energy World. “At DONG Energy we currently have four projects under construction in the UK, which will provide another 2.7 gigawatts of offshore wind power.”
When a drum containing radioactive waste blew up in an underground nuclear dump in New Mexico two years ago, the Energy Department rushed to quell concerns in the Carlsbad desert community and quickly reported progress on resuming operations.
But the explosion ranks among the costliest nuclear accidents in U.S. history, according to a Times analysis. The long-term cost of the mishap could top $2 billion, an amount roughly in the range of the cleanup after the 1979 partial meltdown at the Three Mile Island nuclear power plant in Pennsylvania.
The cost of offshore wind power in the North Sea is 30% lower than that of new nuclear, writes Kieran Cooke - helped along by low oil and steel prices, reduced maintenance and mass production. By 2030 the sector is expected to supply 7% of Europe's electricity.
A Japanese court on Wednesday turned down a class action lawsuit seeking damages from nuclear plant makers Toshiba, Hitachi and GE over the Fukushima meltdown disaster, the plaintiffs, one of the companies and a report said. About 3,800 claimants in the suit, hailing from Japan and 32 other countries including the United States, Germany and South Korea, had sought largely symbolic compensation from the nuclear power plant manufacturers.
Under Japanese liability law, nuclear plant providers are usually exempt from damage claims in the event of an accident, leaving operators to face legal action. The plaintiffs' lawyers, however, had argued that that violated constitutional protections on the pursuit of happy, wholesome and cultured livelihoods.
A provisional estimate from the British government shows the amount of electricity generated from renewable energy set a record last year.
A monthly update from the British Department of Energy and Climate Change finds the share of electricity generated from renewable energy was a record 24.7 percent last year, which marked an increase of 5.6 percent from the previous year.
On a quarterly basis, the DECC said fourth quarter data show the share of renewables increased year-on-year by 5 percent.
"The increase reflects increased capacity, particularly in solar photovoltaics and onshore and offshore wind," the government's report said.
Koide Hiroaki has spent his entire career as a nuclear engineer, and has become a central figure in Japan's movement for the abolition of nuclear power plants.
