True enough, but at the end of the day what the people care about is the amount of pollution per unit volume of air, because this is what you breath. There's nothing one can do about population density, so Shanghai has to settle for a substantially lower percentage of car ownership and use than Western cities with the lower densities.On the topic of pollution, Shanghai has far fewer cars per head than any western city. I went back last year and there were far more cars than five years ago when I lived there, but even so, these are all new cars so even if standards are lower I suspect that pollution per car is still not bad.
The big polluter a few years back was the open coal dumps by the river, even right in the middle of Lujiazui. The barges would bring coal in and it would get dumped on a pile. As a result the whole place used to be covered in coal dust, and this was before any of the coal even got burned. Most of this seemed to be gone last year though I've no doubt a huge amount of coal is still used.
The worst thing from a visibility (and so photo) point of view was and still is the humidity. Slap a polarising filter on your camera in Shanghai and you'll be amazed at the difference, even when it seems like a clear day.
"with a few years delay"...that's what was written, and that's what it is (u also confirmed that in ur post)...the rest is ur usual "climbing on the mirrors" thing.EU went Euro 4 in 2006/07, which is 3 years ahead of Shanghai. Given that the next level is half of the emission of the current one, and factoring in vehicle growth, 3 years makes a huge difference.
- news.xinhuanet.com, 2007-08-27According to estimates by CNPC [China National Petroleum Corporation], the full operation of the second West-East pipeline [natural gas] will raise the ratio by one to two percentage points, while replacing 76.8 million tons of coal and reducing emissions of sulfur dioxide by 1.66 million tons and carbon dioxide by 150 million tons.
The first West-East pipeline, which pipes gas from the Tarim Basin of Xinjiang to Shanghai, transmits 12 billion cubic meters of natural gas annually.
By connecting Central Asia to China's economically prosperous Pearl River Delta and the Yangtze River Delta, and linking natural gas fields in the Tarim, Junggar, Tuha and Erdos basins, the second West-East pipeline would improve China's energy consumption structure by increasing natural gas use and promoting international energy cooperation, said experts.
China's booming demand for natural gas has prompted fierce competition.
China Petroleum and Chemical Corporation (Sinopec), China's second largest oil firm, said it would start construction of its Sichuan-to East-China Gas Project to transmit gas from the Puguang field in southwestern Sichuan Province to Shanghai at the end of this month.
The Sinopec project is estimated to have a total investment of 63.2 billion yuan (8.3 billion U.S. dollars). Gas supply is expected to commence by the end of 2008, said the company in its interim results.
Many of these so-called western cities have way too many vehicles and pollution, and therefore they waste too much energy. These western cities should learn from Shanghai instead. Lower percentage of car ownership is actually a good thing.True enough, but at the end of the day what the people care about is the amount of pollution per unit volume of air, because this is what you breath. There's nothing one can do about population density, so Shanghai has to settle for a substantially lower percentage of car ownership and use than Western cities with the lower densities.
I was just pointing out the significance of the 'with a few year's delay', which I believe makes a rather big difference. Each emission standard allows about half as much pollutants as the previous one, and vehicle numbers have grown exponentially - do the maths. It means total annual emmisions have still been steadily increasing, and the more the delay in adopting new standards the faster the increase."with a few years delay"...that's what was written, and that's what it is (u also confirmed that in ur post)...the rest is ur usual "climbing on the mirrors" thing.
Percentages of emissions cut and anything else (though important on the whole) has nothing to with that simple and true statement u previously denied, and now directly confirmed (as it is simply true), but try nevertheless to indirectly deny...
Look, the current discussion is about total emission, not so much personal emission. Vehicle use and emission per person is undeniably lower in Shanghai than in Western cities, but total vehicle use and emission per square metre of land is a totally different kettle of fish. Unfortunately the amount of air doesn't increase as population density increases, so the notion of total emission is actually more relevant. So if we are to enjoy good air quality simply 'lower car ownership' won't do - it has to be a much, much, much lower percentage. Judging by the shear number of my extended family members and friends in China have cars and once they do they forget everything public transport, and this is reflected in the wider society, I'm not sure Shanghai is going down the right path.Many of these so-called western cities have way too many vehicles and pollution, and therefore they waste too much energy. These western cities should learn from Shanghai instead. Lower percentage of car ownership is actually a good thing.
Therefore, your concept of "has to settle for a substantially lower percentage of car ownership" is stupid.
Thanks, but where is the focus? I hardly find it, kind of out of focus at auto focusing I have to say, Severiano perhaps it's about time for you to buy a new camera like GF-1, NES and EP2 :cheers:Heres some pics I took today
