Renewable energy may play a huge part in helping to achieve the ambitions of the Paris Agreement, now in force and under discussion at COP22 climate talks in Marrakesh, writes Steffen Böhm. But it can never be the whole story, and nor does it relieve the need for deeper changes in how the world works.
In one reality, the government recognises climate change, signs the Paris agreement, and commits to its 1.5C target, writes Matthew Adams. In another, it promises a new London runway that's predicated on sending aviation emissions soaring for decades to come. Now repeat after me: 'Everything will be fine!'
The UK government today announced that Heathrow, already the UK's busiest airport, is its 'preferred option' for a new runway in southeast England, writes Simon Evans. It's just too bad about the climate: the airport expansion implies that aviation emissions alone could take up half to two thirds of the UK's 'carbon budget' for the country to comply with its 1.5C Paris Agreement target.
Should it be Heathrow or Gatwick? The answer, writes Keith Taylor, is neither. For climate and pollution reasons alone the UK should be scaling back on aviation, and in any case projections of future demand have been monstrously exaggerated. Step 1: a 'frequent flyer' tax on the 15% of people who take 70% of flights.
International investors worth a collective $24 trillion have warned car manufacturers that they must 'get with the beat' on climate change, writes Terry Macalister. If car makers fail to shift to low emission models, they will face a large-scale sell-off of their shares.
London Mayor Sadiq Khan promised electors that he would be the 'Greenest Mayor ever'. In spite of his apparent support for a new Thames road crossing in East London and an expanded London City Airport, he still has huge opportunities to make good his pledge. And Green Assembly Members will be working hard to make sure he does.
Using carbon markets to 'offset' industrial pollution is a failed experiment of 19 years duration, writes Chris Lang. But the International Civil Aviation Organization, which holds its General Assembly later this month in Montreal, is determined to offset its emissions - up 76% in 12 years - rather than constrain or reduce them.
It's time for UK citizens to #takebackREALcontrol by challenging the anti-democratic powers that control our country, our economy and our lives, retiring Green Party Leader Natalie Bennett told her party conference this weekend in this barnstorming speech. And that's a challenge only the Greens are prepared to take on.
Hydrogen made from renewable electricity is already fuelling vehicles at affordable prices, writes DAVID THORPE. But now the 'green' fuel is set to go from niche to mainstream - powering not just cars, trucks and buses, but storing surplus renewable energy on sunny and windy days, then to be burnt in gas turbines or fuel cells to supply the grid with reliable power on demand.
Traveling in the US by boat and train visiting solar laboratories and environmental groups, Keith Barnham found many successful community initiatives in renewable electricity, and brings news of progress towards the ultimate renewable challenge: a solar fuel that could eventually replace gasoline in cars, trucks, buses, trains and aircraft.
Following the vote to leave the EU, the UK's energy and climate change policy faces major challenges, writes Paul Brown, with new nuclear power and a third London runway at Heathrow runway looking like the first casualties.
Communities on Jeju, South Korea's 'island of peace', are resisting a second airport that's threatening the island's farming, nature, culture and way of life, writes Rose Bridger. Linked mega-projects include an 'Air City' of shopping malls, hotels and offices, plus high-speed transport corridors, luxury resorts, casinos, theme parks and golf courses - all catering to wealthy outsiders.
The government's new 'strategy' for cycling is a feeble attempt to hide huge cuts to local transport budgets with a minute line of funds that would take over 2,000 years to bring the UK up to Dutch cycle lane standards, writes Donnachadh McCarthy. We must demand better!
Earlier this year, 13 climate activists were sentenced for aggravated trespass after blocking a runway at London’s Heathrow airport. For Kara Moses, the protest was part of her Buddhist practice of loving kindness to life and planet.
Planned air transports of high-enriched uranium from Dounreay in Scotland to the US state of Tennessee would risk of accident or a terrorist seizure of weapon-usable nuclear material, writes Ernie Galsworthy. The motive for the transport appears to be purely commercial - and would thus put the public at needless risk for the sake of a cut-price nuclear waste / fuel deal between US and UK authorities.
World leaders are meeting in New York today to sign the Paris Agreement on climate change, write Stephen Buranyi & Oliver Tickell. But the world just failed a big test of its commitment to the Paris targets by deadlocking on IMO proposals to limit emissions from international shipping.
This week, the International Maritime Organisation could act to curb fast-rising emissions from shipping under the Paris Agreement, write Barry Gardiner & Richard Burden. But there are growing fears that the UK government may seek to delay and obstruct vital progress.
The state government of Ekiti sent bulldozers to clear farmland for a new airport without even consulting the farmers who owned it, writes Rose Bridger. Crops, buildings and trees were all flattened. But the farmers fought back - and have now won a major legal victory that will inspire and empower other mega-project afflicted communities across Nigeria, and beyond.
Two heavily armed, UK registered ships are currently engaged in the transport of UK sourced plutonium across the Pacific, writes Tim Deere-Jones. Details of their safety inspection records, survey status, voyage routes and location have been suppressed in the interests of security but the lack of transparency breaches a number of international safety standards.
It will take decades to completely leave fossil fuels, writes Richard Heinberg. But we can do it, starting with the easy stuff: going big time for wind and solar, raising energy efficiency, replacing oil-fuelled vehicles, and moving to organic farming. But deeper changes will follow as we transition to a more enduring sustainability - consuming better, and much less.
The Chancellor's 'sport not sugar' move to tax sugary drinks was extremely welcome, writes Simon Bullock. But we need a similar Treasury approach to protect people from other threats too. So how about tackling the air pollution that's killing tens of thousands of Britons a year?
Low Emissions Zones have their place in cleaning up the UK's worst air pollution hotspots, writes Richard Howard. But we also need to adopt fiscal measures to encourage a shift away from diesel vehicles, at once delivering cleaner air, increased tax revenues, and lower carbon emissions.
Improved technology and falling costs are moving electric car sales into the fast lane as manufacturers seek achieve significant economies of scale, writes Kieran Cooke. And now China is leading the EV charge with its plans for 5 million plug-in vehicles by 2020.
High Speed UK is the greener, well-connected alternative to HS2, write Colin Elliff, Andrew Coulson & Stephen Stretton - and it would save taxpayers billions. Financed by taxing property owners in connected cities on their windfall gains, HSUK would create a low fare, high capacity, interconnected railway network which would generate huge long-term profits for the nation.
