• The Corrective Work Order (CWO) was introduced on 1 November 1992. In the past, littering offenders only had to pay a fine, but later they had to participate in mandatory labour as well.
• Under the supervision of the health inspector, offenders are required to wear a vest printed with the words “Corrective Work Order” while cleaning up the neighbourhood. The objective is to make these offenders understand the consequences of littering.
• In 1993, the first batch of convicted offenders cleaned up litter in public places such as parks and beaches. The cleaning areas for CWO was later extended to housing estates.
• Besides paying a fine (up to a maximum of 5,000 Singapore Dollars), offenders are required to undergo 3 to 12 hours of CWO depending on the severity of the offence.

The National Environment Agency issued a statement yesterday stating that the number of offenders convicted to Corrective Work Order by the Court has increased significantly. There were about 2,600 tickets issued for Correction Work Order last year, which was 30% more than the 2000 tickets issued in the previous year. （Lianhe Zaobao, 8/5/2019）
