They solved for the equilibrium, China equilibrium of the day

China will be less severe with its smog curbs this winter as it grapples with slower economic growth and a trade war with the United States, according to a government plan released on Thursday.

Instead of imposing blanket bans on industrial production in the Beijing-Tianjin-Hebei area as it did last winter, the Ministry of Ecology and Environment said it would let steel plants continue production as long as their emissions met standards.

Targets for overall emissions cuts have also been revised down. In the next six months, 28 cities in northern China are required to cut levels of PM2.5 – the tiny airborne particles that are most harmful to human health – by about 3 per cent from a year ago.

That is less than the 5 per cent cut proposed in an initial plan seen by the South China Morning Post last month.

Meanwhile, the new plan stipulates that the number of days of severe air pollution should be reduced by about 3 per cent, also revised down from 5 per cent in last month’s draft.

Here is more from Orange Wang at SCMP.  As I am sure you all know, air pollution (and I don’t just mean carbon emissions) is one of the great underrated problems in the world today.  The trade war with China is making it worse.
