@Alien. I'm not sure Chinese buses spew less crap.
@okly78. Tengchong was nice and all with a decent hot spring, but maybe just spend your week exploring Nujiang as it's better scenery. Maybe if we could cross into Myanmar from Ruili I'd rank Tengchong a bit higher.

Hi Alex,

Thanks for the suggestion, I was attracted by the scenery in February as shown in the below chinese travel blog :

Will be visiting in late Dec, wonder how is the scenery is like. Looking forward :)

I also know there is a village in tengchong where the yellow golden leaves in late November to dec is very beautiful :

Ahh, I went during summer, but I have heard of that village, so maybe worth while since you are going around that time. Also, I think there is a better road than I traveled on to Tengchong, so go for it.

@Alex: compare miles per gallon of car, bus, train and airplane & divide by no. of passengers per vehicle.

@Alien. compare how much coal black 1000 api smoke Chinese bus spews out vs jet engine.

@Alex: Doesn't make up the difference, Alex, and the newer buses don't do this so much anyway.

@Alien. Maybe not in co2, but one polluting bus at ten hours will spew 10x more of every other air pollutant imaginable. Chinese jet engines are serviced and monitored to international standards. Chinese vehicles, not so much.

Airplanes have three major problems: they are inefficient, they are big, and they run on toxic fuels. A fully laden A380, according to its' engine maker Rolls Royce, uses as much energy as 3,500 family cars, equivalent to six cars for each passenger. 1 Long haul flights produce on average twice as much emissions per mile traveled per passenger than cars and short haul flights produce three times as much.

I can't believe this. One of the great protectors of forum etiquette and self appointed gatekeepers has hijacked this thread.

@Alien: What, pray tell, does the fuel consumption of an A380 have to do with riding in a jeep to Tengchong? Is it necessary you impose your environmental beliefs on others? If there are flights to Tengchong they are going with or without @okly78. The only additional pollution impact of flying there is the marginal weight of @okly78 and his stuff.

The link you provided is to poorly written website with misleading and irrelevant statements of non facts. For example "In late May, EPA is scheduled to release an endangerment finding that is expected to show that greenhouse gas emissions from aviation puts human health at risk." Anticipation of some undated announcement about risk to human health sounds like wishful thinking for true believers to me.

Your comparison of the A380, a double-deck, wide-body, four-engine jet airliner capable of carrying 585, up to 853, people at 900 km/h for 15700 km, to a Jeep leaves me scratching my head.

Are you seriously suggesting A380's fly to Kunming to Tengchong?

@okly78: To placate @Alien, I suggest you walk to Tengchong. You will see a lot more stuff and, if you don't fart or exhale, you will have minimum air quality degradation impact.
