On July 6, the world recorded its hottest day, in a week that saw records broken three times, raising concerns about climate change.

Scientists say these extreme temperatures should not be seen as isolated incidents but as part of a larger pattern of human-induced global heating that has been unfolding over the past 150 years. Heatwaves are affecting regions from the United States to Europe and China. In Hong Kong, the frequency of “very hot” days – when temperatures reach 33 degrees Celsius or higher – is on the rise.
While Hong Kong’s greenhouse gas emissions fell drastically over the pandemic years to their lowest in two decades, they have started to rise again. This underscores the need for more urgent efforts from the government to address climate change.

With electricity generation accounting for nearly 70 per cent of Hong Kong’s carbon emissions, the government can take drastic action to cut emissions simply by reviewing its agreements with the power companies. It should also turn its attention to the next biggest source of greenhouse gas emissions: the transport sector, with road transport being the primary contributor.
The government should consider setting more ambitious goals in electrifying commercial vehicles. In 2021, it made progressive efforts towards carbon neutrality by announcing a road map to popularise electric vehicles. But as of April, the latest month for which data is available, Hong Kong still had just 39 electric public buses and five electric taxis in operation.
