Environmental Management Policy

In facing intensified global warming and frequent climate change, tackling climate change has been fused into the overall strategy of national economic and social development. A solemn commitment has been made on striving to achieve “Dual Carbon Goals” of carbon peak and carbon neutrality with adopting more vigorous policies and measures for carbon reduction. To cope with the national development strategy, Macao S.A.R. is also focusing on green development by chartering the direction of attaining the goals for carbon reduction.

Macau International Airport as one of major infrastructures in Macao and the gateway to other countries and regions, Macau International Airport Co. Ltd. (CAM) has a spontaneous sense of responsibility of taking the lead in our respective sector to connect with the overall national and regional green development at an accelerated pace, while managing the Macau International Airport with the core value of "Safety, Efficiency and Effectiveness”. In this regard, CAM has set up the relevant management teams to foster the sectoral stakeholders’ engagement practices through establishing “Airport Environmental Management Programme” with appropriate measures. It materializes the milestone in our trajectory of carbon reduction, resulting to facilitate our Green Airport in a more exemplary way.

This Environmental Management Policy is the unwavering commitment of CAM in its environmental management and carbon reduction. It guides our stakeholders to act out its commitment in line with our green development direction. The principles of CAM’s Policy in green development are focusing on:

  • Actively work with our stakeholders to deliver our climate change mitigation and adaptation measures;
  • Strive to reduce our carbon emissions proactively, commit to working with government and other stakeholders to reach the final destination of net-zero carbon emissions as long-term target;
  • Commit to protecting the environment, including prevention of pollution and minimizing the adverse environmental impacts of its airport management and operational services.
  • Fulfill all compliance obligations and perform regular environmental assessments on the Airport’s operations in order to ensure compliance with the specified requirements from our interested parties;
  • Strive for continual improvement on environmental management system and environmental performance through risk-based thinking, address the respective risks and opportunities of all relevant environmental aspects;
  • Minimize adverse environmental impacts resulting from the life-cycle of airport activities, products and services that interacts or can interact with the environment;
  • Allocate necessary resources on continual improvement on environmental performance during the Plan-Do-Check-Act cycle in accordance with the financial and technical capabilities;
  • Commit to consuming energy efficiently, minimizing waste generation, reuse and recycling waste where practicable;
  • Promote protection and enhancement of ecosystems and biodiversity while maintaining the safety operations;
  • Ensure that outsourced processes are controlled and adhered to CAM’s Environmental Management Policy and Airport Environmental Management Programme;
  • Influence and collaborate with our stakeholders to operate to the principles within this Policy and jointly find solutions to the key environmental issues that are beyond the direct control of CAM.

Airport Carbon Accreditation (ACA) Programme

"MIA had participated in the ACA Programme from organized by ACI and accredited with Level 2 – “Reduction” since 2014, with the target set as “Reduce Carbon Emissions per Movement by 20% in 2018 compared to 2012 Level”. Through continuous effort, to reduce emissions, MIA had reduced 40% of carbon emissions per aircraft movement in 2018 compared to that of 2012.

In 2019, MIA had set another target “Reduce Carbon Emissions per Movement by 30% in 2028 from 2018 Level” and revised our Carbon Management Plan. MIA started to implement more environmental projects and measures that can be done to achieve the target, such as replacement of aging chillers with energy efficient ones in the Passenger Terminal Building, LED light replacement projects in various areas within MIA, replacement of aging vehicles with low or no emission vehicles and look for opportunities to recycle more wastes originated from daily operations in MIA.

Subsequent to the implementation of some green projects and measures, as well as the joint efforts from concerned entities, the absolute carbon emissions in 2022 had already reduced by 39% compared to the average of the total carbon emissions of the previous 3 years. In this post COVID-19 pandemic period, MIA is striving to achieve further carbon reduction.


Green Projects

Vehicle Replacement

As part of the Carbon Management Plan, until the end of 2021, MIA had replaced and purchased eight hybrid and three electric vehicles.

Food Waste Recycling Programme

MIA implemented the Food Waste Recycling Programme since 2013. In the past years, the Food Waste Composter treated the food wastes generated from the uneaten in-flight meals and the food wastes from staff canteen in Servair Macau and the food wastes from Airport Restaurants, Plaza Premium Lounge and coffee shops in PTB. Until the end of 2022, the Food Waste Composter had recycled over 112, 000 kg of food wastes and turned them into organic compost, which were used for grass growing near the Runway area by Landscaping staff. This had helped to reduce the amount of wastes sent for incineration.

Green the Airport with various plants

All kinds of plants are located in different areas of the terminal building, namely: Calathea Makoyana, Rhapis excelsa, Fagraea ceilanica, Schefflera arboricola and Dracaena “Lemon Lime” placed in departure lounge. The plants rotate every season.  Green plants can reduce emission of carbon dioxide, purify air and improve air quality, MIA determine to provide a memorable green airport experience for the all passengers!

Replacement of Airfield Ground Lightings (AGL)

Since 2013, with the subsidy from Environmental Protection and Energy Conservation Fund of Macau SAR Government, MIA had replaced the traditional Taxiway Edge Lights, Stop Bars, Taxiway and Apron Centre Line Lights. Since 2017, CAM had also invested in replacing the Sequential Flashing Lights (SFL) and Runway Threshold Identification Lights (RTIL) on both Runway 16 and 34 with LED ones. After the replacement of the abovementioned AGLs, over 16,000 kg of carbon emissions can be reduced.

Replacement of Chillers to Energy Efficient Models

In 2022, MIA had replaced the aging chillers with energy efficient models. After the replacement of chillers, total electricity consumption had decreased 11% in 2022 compared to that of 2021. These chillers consume more environmental-friendly type of refrigerant, which has a lower global warming potential than the type of refrigerant used for the previous chillers, therefore contributed to reduced carbon emissions.
