Special Report – Green Macau

The need to walk the talk

MB September 2021 Special Report | Green Macau


The special report that follows on the next 20 pages is not just about renewable energy, but in that particular respect Macau needs to stop wasting time: in terms of energy supply, we are basically no different today as we were 20 or 30 years ago, importing nearly 100%.

The terms climate change, reduction of emissions and waste, sustainability and energy transition goals, have all become part of our daily language.

But when it comes to walking the talk, Macau seems to be headed in the opposite direction from many places around the world, including Mainland China, which has taken decisive steps in the right direction.

If it’s certainly not for lack of financial resources, could it be the absence of the right conditions?

As the reader will discover, plenty of specialists believe Macau has excellent conditions for solar energy, as well as for offshore wind farms in the Region’s own 85 km2 of territorial waters.

Along with talk of green energy comes pollution (particularly the unwieldy problem of solid waste), recycling, the impact of tourism and our relationship with the region around us (the Greater Bay Area). We end with another warning that can’t be repeated too often: be worried about a rise in sea level; Macau is very exposed.

P.S.: The impact of sea-level-rise on Macau is in fact one of the issues driving Portuguese concept artist and illustrator Ricardo Lima, who exhibited his sci-fi work MO2049 last year at the Taipa Village Cultural Association. This special report is illustrated with images by Ricardo Lima, to whom we are grateful for the collaboration.

Only 5 photovoltaic interconnections

Almost all the energy consumed in Macau comes from Mainland China. There is a long way to go in terms of renewable energy despite the existing potential


To charge and raise awareness

Implementation of the “polluter pays” principle is proceeding slowly. The government is focused more on awareness-raising and incentive initiatives, such as the Macau Green Hotel Awards.


Tackling the solid waste malady

Mass tourism translates into too much garbage. It has been a serious problem and prompt action is need. The Government is aiming at a 30 per cent reduction in solid waste.


Hazy problem

Air pollution is one of Macau’s most serious environmental problems. But no matter how Macau improves its habits, the Zhuhai Jinwan Power Plant remains right next door…


Environmental awareness: before and after Hato

Macau residents’ environmental awareness has improved significantly in recent years, but more is needed


Tá Pau* recycled

Reducing food waste is a Government priority, but 72 per cent of local restaurants still treat food waste as regular domestic waste.


“It is very unlikely that Macau can be a sustainable, energy-efficient city in the short and medium term.”

Environmental science expert Wai Ming To is sceptical on solar or wind energy being developed in Macau. He argues instead that the city can do slightly better is to adopt smart/intelligent building systems that optimize the use of electricity for air-conditioning, and air and water heating


Eco-friendly hotel

Most hoteliers actively introduce initiatives that contribute to cost savings, but more investments are needed


GBA and the case for legal synchronization

Experts call for the “creation of a mechanism of legal cooperation in environmental governance” and  “collaborative environmental governance” in the Greater Bay Area


Sea level in Macau “is now rising at an accelerated rate”

Scientists’ prediction for a medium-emission scenario is that by 2060 water levels will have risen 34 cm in Macau, about 20 per cent higher than the global average
