This is commendable but, The massive air pollution occurring this winter throughout the country proves that we still have a lot more work to do.
The big foreign investments in 2016 included two in Australia, two in Germany and two in Brazil, as well as deals in Chile, Indonesia, Egypt, Pakistan and Vietnam.
- In Australia, China Light & Power struck a $1.1bn deal, buying power from wind and solar farms.
- In Chile, Tianqi Lithium spent $2.5bn acquiring a 25% stake of a lithium miner and processor. (Lithium is essential for lithium batteries used in electric vehicles and home battery storage.)
- In Germany, Beijing Enterprises Holdings Ltd spend $1.6bn on a Waste to Energy development.
Agree, the size and depth of this global challenge are massive, so are the opportunities, it's gonna be a long run.To be honest, at the current technological level, the best we can do is alleviating symptoms, but not solving it at root. The primary sources of air pollution in any industrialized nation are:
1. Power Generation
2. Motor Vehicle
3. Heating
4. Industrial Production
5. Natural Geological Events
1. Coal fire station can be modified to be more efficient and emission can be somewhat reduced, but at the end of the day, a large and powerful industry WILL require large amount of power. Fission station does help somewhat, but it also have its own set of problems. Eventually solving the problem would require technological breakthrough in form of commericial available fusion. BTW, I don't consider de-industrialization to be a solution, it is equivalent to treating foot fungus by cutting off your leg.
2. Motor Vehicle problem is two-fold. The first one is the raw number of vehicles. The second one is the CONCENTRATION of vehicles. US has a lot of vehicles as well and it contributes to a large part of the nation's air pollution, but since US population are more spread out, the smog effect is reduced quite a bit. This problem requires breakthrough in electrical vehicle manufacturing (especially the electricity storage technology) and more urban-rural development planning.
3. Household Heating is also a major source of pollution. There is a reason why China's smog problem is mostly concentrated in winter time. Gas heating, of course, is more efficient and less polluting than coal heating. However, that just shifts the problem from one fossil fuel to another. Electricity heating requires more infrastructure and place heavier burden on the grid. Also, at the end of the day, electrical heating is also a transfer of problem from issue 3 to issue 1. That energy has to come from somewhere.
4. Industrial production, of course, produces air pollution, but to be honest, much of it is also from various heating process, which goes back to the previous question of where to get the energy. Other process also release a variety of air pollution. They control can also only come from better technology.
5. Geological and Meteorological events have a very large impact on the air pollution, especially the highly visible smog events.

Take Beijing for example, Greenpeace's report indicate that Beijing's air pollution is actually falling quite a bit on yearly comparison, but local weather events has a much more pronouced effect in the short period. (For those of you that don't know, Beijing is a surrounded by mountain on three sides. It makes a very militarily defensible position in ancient time, but a low pressure front during winter time can trap smog in the area.)
Of course, this is just PM2.5. There plenty of other indicators, such as PM10.

Because of coal burning. Why not retrofit buildings with natural gas?This is commendable but, The massive air pollution occurring this winter throughout the country proves that we still have a lot more work to do.
