MACAO, June 5 (Xinhua) -- The estimated amount of greenhouse gas emissions in China's Macao Special Administrative Region (SAR) decreased slightly in 2021, according to a report issued on Sunday by the SAR government's Environmental Protection Bureau.

The emissions last year mainly came from land transport, power generation, businesses, households, the service industry as well as waste incineration, the report said, noting that the local emissions in the past decade showed a downward trend.

In 2021, six monitoring stations in Macao recorded 93 percent of the days as having "Good" or "Normal" air quality, about the same as in 2020.

Meanwhile, due to the recovery of social and economic activities, the average concentrations of pollutants except fine suspended particulates (PM2.5) showed growth in 2021. Water and electricity consumption as well as urban solid waste volumes also rose in the past year.

To reduce emissions, the Macao SAR government has adopted legislation requiring gas stations and oil depots to install oil vapor retrieving systems and set standards on exhaust gas of vehicles and oil products, among other measures, said the report.

On Sunday, Macao called on the public to turn off unnecessary lights for one hour in the evening as part of a campaign led by the Environmental Protection Bureau to mark the World Environment Day. Three cross-sea bridges, various government buildings, entertainment venues, banks, hotels and some tourist spots all responded to the initiative.
