JUST BEEN WATCHING THE BBC NEWS
the subject on deasel pollution and how much the UK government put into research
it has now come to the subject of pollution of tyiers on the road giving of pollution
harmful to lungs etc i dernt have any beans for fear of pollution

Never a mention of the crap planes put out! What about all people that fly around the planet, When they could use video conferencing, Sorry they must have their goodies!.I lived near the South downs and watch ed the unspent fuel being dumped, from the rear. icon_fran

Pollution due to tyre wear is a relatively recent set of investigations. Current estimates vary, and a lot more work is required. But there is no doubt that is contributes significantly to both air and water pollution. Two issues; the “ dust” airborne; and the powdered compound that washes off the roads and enters the drainage systems. As well as rubber, tyres contain polymers and micro beads. They enter the water system from drainage and eventually end up in the sea. Unlike micro beads in soaps and shampoos, etc, which are now being eliminated, there is currently no control of the compounds in tyres. Estimates are that at least 10% of the microbead plastic and micro particle plastic pollution comes from tyres.

Unspent fuel dumping is of almost total insignificane in aviation pollution; the major issue is over 500 mégatonnes of Carbon dumped into the atmosphere ( increasing 5-10% per year). As is the water vapour from exhausts.
There are issues because flying is so cheap, and also aviation fuel, internationally is not taxed.
The UN via ICAO is working hard to get global controls put in place. The EU is sponsoring a huge heap of research in 3 areas;
1. Getting social attitudes and work practices to reduce the need to fly.
2. Alternative aircraft fuels; and propulsion methods
3. New technology to reduce power on taxying etc ( electric wheel drives to allow engine-off taxiing, electric catapults for takeoff, etc

There are also carbon-swapping schemes. ( though these aren’t effective). It’s not true to say «  nothing is happening »

The elephant in the room has been largely ignored so far.
It has been calculated that 15 of the largest cargo ships in the world, put out the same amount of pollutants, particulates, NOX, SO2 etc, as all the vehicles in the world.
If you look at a website called https://www.marinetraffic.com/en/ais/ho ... 9.4/zoom:7 which tracks live ship movements,
and see the number of ships transitting the english channel - the 15 ship calculation could be somewhere close to the truth.
Especially as some of the larger ships will be burning heavy fuel oil.
But of course vehicles are easy to tax - unlike ships!
Brexit is like watching your library being burnt down by people who never learned to read.

Well said icon_clap one of hundreds of the huge cruise ships that now operate churn out as much as 1 million cars do per day when burning heavy oil which i think all of them do,its all about profit.

Cruises; indeed; by far the most damaging, environmentally, holiday you can go on.
In countries where there are pollution controls they go to the reserve tank, which has slightly better fuel; once outside national water, they switch to the main tank which has filthy fuel. The amounts of pollutants they churn out is immense. NOx, Sulphurs as wellThey are pretty bad for your personal health, too; fresh sea air? On deck, on a cruise ship, unless you are in a gale, you are exposed to, on average, 5 times the level of harmful diesel particulates and soots than you would experience in London or Paris on the days when they give you the warnings to stay indoors and they put in the traffic control restrictions. Depending on wind and ship direction and speed, aft of the funnel ( where the pool usually is) is the worst.
They also chuck all rubbish over the side, plus all effluent, grey and black water. The “ digesters” and reverse osmosis plants ( if fitted) are only in use in port and in territorial waters.
Commercial freight shipping, of course, does the same. Another area where it’s proving difficult to get global standards agreed.
There is also close shore environmental damage; for instance, Venice is having huge problems, despite tightly controlled speed limits, due to shipwash disturbing the substrates in the channels leading into the port. And Canada, Alaska, Norway, are having eco problems with the cruise ships on the coasts and The fjords on these whale watching trips

Yep. More if you include the O2 element in the CO2. Strangely, the NOx emissions have a slight global cooling effect as the O from NOx combines with High atmospheric O2 to produce more O3
