And 16-container ships create as much pollution as all the cars in the world. Perhaps these ships are softer targets to correct than tens of millions of cars? http://www.dailymail.co.uk/sciencetech/article-1229857/How-1...

sure, lets shut down everything and go tribal

Here in Europe (well UK and Spain whee I have lived and owned a car) you need to get a check every year for older cars, and that includes an emissions test. Don't you get that in the States / Canada? (It would appear that the study was done in Canada). Saying that, go to many less developed country and the cars are far worse condition. My friend always used to claim that the environmental cost of producing a new car…

Yes, Ontario (where the study was done), has such a program. An emissions test is required every 2 years on every car more than 7 years old. The major loophole is that if your car fails, you only have to spend $450 to fix the problem. Spending $450 to improve emissions gives you a pass whether or not it actually fixed the problem or not. Ontario uses a lot of salt in the winter, so there aren't a lot of old cars on t…

The salt solution to the pollution problem is somewhat convenient in the end. Cars do rust to pieces far quicker in Ontario than elsewhere.

And 99% of those 25% are probably in the developing world, and the ex-USSR. I've been all over the planet, and I have yet to see trucks which emit thick black smoke straight from the engine (no exhaust system) like the ones Russia and other ex soviet states are absolutely chock full of. Edit: Also, only place on earth I've ever seen a petrol pump with the choices of 60, 80, or 85 octane fuel. Pinkpinkpinkpinkpink.

>Also, only place on earth I've ever seen a petrol pump with the choices of 60, 80, or 85 octane fuel. If youv'e ever seen a pump with diesel, you've seen a pump with 15-25 octane [1]. Also, I wouldnt confuse octane with energy content -- pure ethanol has an octane rating of 100+, despite having lower energy density than pure gasoline [2].

This actually raises a very good question - how come they don't put cetane number on diesel pumps? It would make me feel less nervous about buying diesel from sketchy off-brand fuel stations...

Can we have some proper references rather than the Daily Mail. Its the UK's equivalent of Fox news. They have a pro car owning readership, so any headline like this will be welcome to them

> Its the UK's equivalent of Fox news

Not really, it's more like something in between the National Enquirer and the New York Post in terms of journalistic quality. Doesn't really make sense to compare it to TV news.

I'm fairly sure that salt does not differentiate between polluting and non-polluting vehicles.

If I'm not mistaken, those ships are more efficient per unit of cargo than smaller ships. It's one of the main reasons they were built.

I can't find the article but Google used to think that replacing cars and coal plants(with clean coal) would be enough to curb CO2 emissions but a new study they just released(last 6 months I think) said it wouldn't matter at all. That has changed their strategy from clean coal to carbon sequestration.
