Anyone who thought switching from diesel to a petrol vehicle would be a good idea might have to think again, if they ever intended to drive into UK city centres. And that’s just the start, if the Oxford plan sets the tone.

Oxford is to become the world’s first zero-emissions zone, as it looks to ban all non-electric vehicles from its city centre by 2020, says the IB Times.

The university town will become the first city in the UK to ban all polluting vehicles from its centre. All petrol and diesel vehicles, including cars, buses and vans, will be barred from six main streets in the centre as of 2020.

Saving money on energy and being trendy may have attracted some buyers of wood burning stoves, but now reaction to air pollution claims is threatening to knock many such sales on the head. Bad news for some who already own them.

London Mayor Sadiq Khan is seeking new powers to ban wood burning in the most polluted areas of the capital, says BBC News. The mayor has written to the Environment Secretary Michael Gove asking for greater powers to tackle air pollution not caused by traffic.

Mr Khan wants to introduce a network of “zero-emission zones” where the burning of wood or coal is completely prohibited. He also wants tougher controls on the sale of wood-burning stoves.

Under the mayor’s proposals only low-emission versions of wood-burning stoves would be allowed to remain on the market. There are currently 187 areas of London where pollution regularly exceeds European limits.

The campaign to demonise diesel cars – above all other causes of city air pollution – rumbles on, as The Local reports. The conundrum being of course that Germany makes vast sums from sales of diesel cars, trucks, buses etc. As usual climate is wrongly conflated with air quality issues.

Chancellor Angela Merkel on Monday pledged a billion euros to help German cities fight air pollution caused by dirty diesel cars, as a scandal strangling the automobile industry threatened to engulf politicians at the height of the election campaign.

Merkel said she was doubling financial aid to cities from a previously announced €500 million, in a bid to stave off the threat of an all-out ban against diesel vehicles.

The public health threat posed by nitrogen oxides (NOx) emissions came to the fore after Germany’s biggest carmaker Volkswagen admitted in September 2015 to fitting millions of cars worldwide with illegal devices to cheat pollution tests.

Earlier this year, DEFRA published a report by the Air Quality Expert Group into the impacts of biomass on air quality. The results make for startling reading.

Among the findings are:

Diesels are in need of some good news after all the recent negative press. The researchers believe their findings are of ‘major environmental importance’.

Researchers have discovered a new reaction mechanism that could be used to improve catalyst designs for pollution control systems to further reduce emissions of smog-causing nitrogen oxides in diesel exhaust, as Phys.org reports.

The research focuses on a type of catalyst called zeolites, workhorses in petroleum and chemical refineries and in emission-control systems for diesel engines.

New catalyst designs are needed to reduce the emission of nitrogen oxides, or NOx, because current technologies only work well at relatively high temperatures.

“The key challenge in reducing emissions is that they can occur over a very broad range of operating conditions, and especially exhaust temperatures,” said Rajamani Gounder, the Larry and Virginia Faith Assistant Professor of Chemical Engineering in Purdue University’s Davidson School of Chemical Engineering.

“Perhaps the biggest challenge is related to reducing NOx at low exhaust temperatures, for example during cold start or in congested urban driving.”

Goldman Sachs, the merchant bank, calls cobalt ‘the new gasoline’ but there are no signs of new wealth in the DRC, where the children haul the rocks brought up from tunnels dug by hand.

Adult miners dig up to 600ft below the surface using basic tools, without protective clothing or modern machinery. Sometimes the children are sent down into the narrow makeshift chambers where there is constant danger of collapse.

Cobalt is such a health hazard that it has a respiratory disease named after it – cobalt lung, a form of pneumonia which causes coughing and leads to permanent incapacity and even death.

Even electric cars can’t cut the mustard in polluted cities, according to this BBC report at least.

Plans to promote electric vehicles in the UK do not go far enough to tackle air pollution, according to a leading government adviser. Writing in the Guardian, Prof Frank Kelly said fewer cars, not just cleaner ones, were the key to cleaner air.

Electric cars produce particulates from their tyres and brakes which are linked to serious health problems. Prof Kelly said that London should lead the way in promoting non-polluting transport policies.

Just last week the government unveiled its strategy for tackling illegal levels of nitrogen dioxide in the air. The key element was a promise to end the sale of all new diesel and petrol cars from 2040.

If cars are to be electric only there will obviously be a massive increase in demand on the National Grid as a result – and that’s only one of a number of major issues arising from such a policy, such as cost and practicality. Whether hybrids would still be allowed is not clear.

New diesel and petrol cars and vans will be banned in the UK from 2040 in a bid to tackle air pollution, the government is set to announce.

Ministers will also unveil a £255m fund to help councils tackle emissions from diesel vehicles, as part of a £3bn package of spending on air quality, reports BBC News.

The government will later publish its clean air strategy, favouring electric cars, before a High Court deadline.

Even buying an ice cream from a van could be a health hazard, in Britain at least, according to the Mail on Sunday’s roadside test results. A pre-existing condition might be triggered by the fumes, they say. The anti-diesel campaign rumbles on.

Diesel-engined ice cream vans are spewing out dangerously high levels of a deadly pollutant which is especially harmful to young children, a Mail on Sunday investigation has revealed.

The engines are kept running while the vans are parked to power their fridges, leaving queuing families to breathe in a pollutant that can trigger asthma attacks after just a few minutes’ exposure and is responsible for thousands of deaths each year.

City life in China

Maybe the courts could order the issue of free anti-pollution masks, pending any government ‘clean-up’ action.

The UK government may face legal action after seeking to delay publishing its plan to tackle air pollution until after the general election, says BBC News.

The courts had given ministers until 16:00 on Monday to set out draft measures to combat illegal levels of nitrogen dioxide (NO2) pollution. A 2016 court ruling said existing measures proposed by the government did not meet the requirements of law.

The general election is scheduled to take place on 8 June.

French anti-pollution car stickers


A colour-coded badge of honour or shame for every car under new French regulations. UK MoT certificates won’t do for city visitors.

UK drivers planning to go to France in the coming months are going to require new ‘clean air’ stickers or face on-the-spot fines for failing to display them, as CLM reports.

Paris, Lyon and Grenoble introduced the new Crit’Air scheme in January to tackle vehicle pollution in their city centres, with another 22 towns and cities said to be planning to follow suit over the next few years.

The scheme requires all vehicles to clearly display an air quality certificate windscreen sticker, or vignette, according to how much they pollute.

An embarrassing U-turn by the promoters of pointless carbophobia as diesel cars get the role of public enemy.
H/T Daily Mail via GWPF

It’s less than 20 years since the Labour government – backed by the vociferous green lobby and most of the scientific community – urged motorists to abandon their nasty, carbon-emitting, petrol-engine cars and convert to diesel.

With hindsight, looking at the names of the politicians who pushed this revolution – John Prescott, Neil Kinnock (then EU Transport Commissioner), Gordon Brown – we should have known it would end in tears. But at the time we were assured that driving a diesel was good for the planet and buying one was doing a public service.

Hard to see bus and train operators giving 40 days of discounts to ‘help the climate’ as so-called climate experts fondly imagine. Pollution, congestion and climate fears all get rolled into one issue.

For years German cities have suffered under the effects of polluted air, mainly caused by diesel cars. But now that it’s nearly the Christian season of abstaining before Easter, experts have a novel solution, as The Local explains.

The Federal Environmental Agency (UBA) and other climate protectionists are encouraging Germans to go on a ‘car fast’ for the season of Lent leading up to Easter.

Katrin Dziekan of the UBA suggested special discounts on Deutsche Bahn and regional train services could be offered to those who abstain from cars for the 40 days between Ash Wednesday and Easter.

The VW diesel scandal has changed opinions.

The VW diesel scandal has changed opinions.


Car sales people may need a new pitch to buyers after this change to government policy. ‘Clean diesel’ is dead.

The Government is reportedly considering a scrappage scheme for diesel cars to improve air quality, reports the Belfast Telegraph.

Drivers should think long and hard before buying a diesel car, the Transport Secretary has said. Chris Grayling suggested motorists should consider buying a low-emission vehicle rather than spending their money on a diesel.

His intervention follows reports the Government is considering a scrappage scheme for diesel cars to improve air quality. The reported scheme would see drivers offered a cash incentive for replacing an old diesel car with a low-emission vehicle.

Variations of this aerosol claim have been around for many years. These researchers seem uninterested in known oceanic cycles which might help to explain the observed temperature changes, instead relying on climate models. But another researcher notes that ‘black carbon emissions in some parts of the Arctic are still quite common’, as confirmed recently here. An earlier study (2007) reported ‘There is, however, at least a fourfold uncertainty in the aerosol forcing effect.’ So it looks like the jury is still out regarding air pollution in the Arctic.

Humans may have been altering Arctic sea ice longer than previously thought, according to researchers studying the effects of air pollution on sea ice growth in the mid-20th Century.

The new results challenge the perception that Arctic sea ice extent was unperturbed by human-caused climate change until the 1970s, reports Phys.org. Scientists have observed Arctic sea ice loss since the mid-1970s and some climate model simulations have shown the region was losing sea ice as far back as 1950.

In a new study, recently recovered Russian observations show an increase in sea ice from 1950 to 1975 as large as the subsequent decrease in sea ice observed from 1975 to 2005.

The predictable war on diesel cars is underway. The days of promoting them as ‘climate-friendly’ are over, in the UK at least. Diesel trucks, vans and buses are overlooked.

London’s air pollution problem is so bad that just five days into 2017 Brixton had already used up its traffic fume allowance for the year, reports iNews.

Brixton has since been overtaken by Knightsbridge as Britain’s most polluted district so far this year. The wealthy west London suburb has exceeded the EU nitrogen dioxide (NO2) limit for a total of 52 hours already this year, nearly three times the legal annual allowance of 18 hours, according to the latest figures from Dr Gary Fuller at King’s College London.

But traffic pollution is by no means confined to these London hotspots.
