Update | Hong Kong’s air quality to ‘drastically improve’ within five years, says Christine Loh
Loh vows 'dramatic' results and says city is on target to achieve its goals, but warns pollution battle must include action on emissions at sea

Hong Kong's air quality will show "dramatic improvement" over the next five years, says undersecretary for the environment Christine Loh Kung-wai.
And she predicts that reductions in pollution should start being measured by the second half of this year
In her most confident pledge so far on the fight for cleaner air, Loh told the South China Morning Post the city is well on target to achieve landmark goals - such as a 20 per cent reduction in sulphur emissions - before 2020.
"There's no question - we will meet these objectives," Loh said.
"Our whole vehicle fleet will be dramatically cleaner in about four or five years … we will see a dramatic improvement in roadside [air quality]."
