Environment correspondent Grace Chua from The Straits Times has been named Singapore's winner at this year's Siemens Green Technology Journalism Award.

Her commentary piece, "Towards a robust clean air strategy", covered a wide spectrum of causes and effects of air pollution, strategies proposed by academics, as well as government and private sector efforts to manage it.

Siemens received over 170 submissions from the Asean-Pacific region, from local news dailies as well as regional trade publications and online media.

Ms Chua, 29, wins a cash prize of $1,000 and a trip to London for the award ceremony and to attend an environment conference. She will also be considered for the regional round of the competition along with six other country winners from Australia, Indonesia, Malaysia, Philippines, Thailand and Vietnam. The results of this round will be announced in September.
