Air quality, green spaces, and environmental policies in Macao (China)

Macao SAR maintains low per capita greenhouse gas emissions at 1.65 tonnes CO2e annually, with total emissions declining 5.69% yearly due to reduced fossil fuel use. Air quality is monitored via six automated stations, showing stable trends amid urban challenges. Environmental policies emphasize pollution control, ecosystem protection, and sustainable development, integrated with Greater Bay Area strategies. Typhoon risks persist, but coastal water improvements and waste management advance sustainability in this densely urbanized region.

Air Quality Index

Moderate

6.5/10

Stable trend

Macao's air quality remains stable with six automated monitoring stations tracking pollutants like PM2.5 and O3. In 2024, O3 caused poor air quality in summer/autumn, while PM2.5 exceeded standards on 11 December days. Roadside stations like Ka Ho reported 40.7% good days.

Water Quality

Good

7.5/10

Coastal water quality improves with 2024 completions of sewage treatment plants near Outer Harbour and Hong Kong-Zhuhai-Macao Bridge. Government monitors via automated networks integrated into China's national system.

Water treatment standards ensure safe supply; pollution from urban sources managed through new facilities.

Recycling System

Macao's Waste Incineration Centre processes all solid waste at 3,000 tonnes/day capacity, expanded in 2024 with new phases and hazardous waste facilities. Recycling promotes conservation-oriented society per 2010-2020 plan.

Green Spaces

Limited green spaces due to urbanization; coastal mangroves and parks preserved amid hills like Coloane Peak (170m). Efforts focus on ecosystem protection within dense urban setting.

Forest Coverage: 0.1%

National Parks: 0

No national parks; emphasis on urban green initiatives and biodiversity challenges.

Environmental Policies

Policies evolve toward comprehensive management: 2010-2020 plan optimizes living environment, promotes recycling, integrates regional green development. Increased ecosystem investment, climate adaptation, pollution control.

Key Policies:

•Environmental Protection Planning 2010-2020
•Pollution Prevention and Control

Renewable Energy: Biomass power plants explored; low emissions from reduced fossil fuels.

Natural Disaster Risk

HIGH

Primary risks from typhoons (May-Nov, peak Jul-Sep); humid subtropical climate with hot summers (33°C) and heavy monsoon rain (2000mm). Seismological monitoring at Taipa Grande.

Climate Change Impacts: Emissions declined 5.69%/year, low per capita 1.65t CO2e; urbanization alters climate, increasing heat/precipitation risks. No specific °C rise or sea level data available; coastal vulnerability heightens typhoon/flood severity in Greater Bay Area over decades.

Sustainability Initiatives

Waste Management

Macao Incineration Centre expanded in 2024 with third phase, new hazardous waste centre; processes 3,000 tonnes/day, supporting recycling-oriented society.

Air and Water Monitoring

Six air stations, VOC/LIDAR systems; sewage plants completed 2024; part of China's 33,000+ station network using AI for pollution tracking.

Emissions Reduction

5.69% yearly GHG decline to 1.17Mt CO2e; low per capita emissions via fossil fuel cuts, public transit expansions.
