Electricity production as I said is getting cleaner every day. Having a zero emission car (powered by renewables) is not an insignificant reduction. It's an almost total reduction. I don't think it will be long before oil is a thing of the past. Shipping and airlines is an issue and I don't see how that is going to change in the near future.
The bigger picture is totally dictated by consumer habits. People want stuff fast and/or cheap. Oil holds that market under it's dirty thumb. If everyone tomorrow decided they no longer wanted to fly abroad on holiday, swap their diesels for EVs, grow their own food or buy locally sourced produce from a market, globalisation and corporations would change their perspective instantly. Unfortunately humans are pretty fickle and the fast and cheap thing is just a result of greed for the most part.
Well that's not comparable.
To add to the above, the link eventually leads onto the "Equa air quality index", which contains data for a number of vehicles.
Interesting how almost all of them are from VAG. What a coincidence.
you do know that the 20 largest ships in the world make more Fumes than every single car on the planet combined. Cars are 2% of all co2 emissions. That's literally nothing. If everyone stopped using all cars overnight we would all still be doomed
If we all have electric cars they still have to be manufactured and we would run out of lithium for the batteries rather than running out of oil... So then we can have a lithium crisis instead and ban all battery powered cars in cities.... O wait.
No they do not, this myth comes from a report on the emission of sulphur only, as sulphur is taken out of car fuels during the refining process. This concentrates it in the type of fuel ships use .

Comparing car emissions with shipping and air travel again are again not really like for like. Not that they shouldn't be counted because what you're saying is totally valid in terms of 'they pollute badly'. Again it's down to where consumers spend their money that starts the trend, do we really need to be shipping things all over the globe? Probably not. Mile for mile air travel is still cleaner than 400 people driving their cars to a single destination... As is a boat load of cars to sell rather than driving them all individually or putting them on trucks or trains. More work does need to be done on shipping/flights.
The battery problem is again a valid issue, mining lithium isn't nice, and once the batteries are depleted, where will they all end up? It's all still in it's infancy and I think there will be huge changes within the next 10 years which hopefully can address some of the issues with batteries.
For me personally, I'm happy to pay slightly more for a green energy tariff, I picked up a Leaf at the weekend for the short journeys we do, I recycle everything that I can, and I'm making a conscious decision to change my eating habits so that my food isn't from all corners of the planet. If others start to adopt the same thought process, companies would soon wake up and start thinking harder about their ecological impact. Consumers drive companies, we've just got complacent and spoiled to the detriment of the environment.
I read that article yesterday and found it to a bit long winded the results i found to interesting. I must admit it made me think about my 15 year old petrol car and if i should change it? But then if i was to change it i would go back to a diesel for the MPG as i work in the middle of the country side and to be honest i wouldn't even feel guilty about it as i do the miles then at the weekend when we go in the city we use my wife petrol focus anyway. I would consider a Hybrid, but it would use the petrol engine of the time on my commute.
