Hong Kong’s target to achieve carbon neutrality in less than 30 years will undoubtedly bring a myriad of challenges and difficulties, but it will also open up new opportunities for Hong Kong. Measures to decarbonise and to adapt to climate change will not only bring about sustainable improvement to the environment, but will also drive the development of a green economy, create job opportunities and promote a green recovery. We estimate that the resources to be devoted by the Government in the next few years can create more than 10 000 job opportunities. Hong Kong must grasp the new momentum for growth brought about by the low-carbon transformation, and seize the collaborative opportunities with neighbouring regions to foster more diversified and sustainable development.
