We must embark on a pathway to net zero greenhouse gas emissions to limit the temperature rise within 1.5°C above pre-industrial levels.
The October 2018 IPCC report Global Warming of 1.5°C highlights that global annual emissions need to be reduced to about half from the current levels by 2030 in order to limit global warming to 1.5˚C.
This goal will only be achieved if net emissions are reduced to zero by around 2050.
Hong Kong is committed to take action under the Paris Agreement. In 2017, Hong Kong released the Climate Action Plan 2030+ and committed to peak carbon emissions by 2020 and to reduce them by 26-36% from 2005 levels by 2030.
But we must agree a pathway to net-zero emissions for HK.
Just as walking on sand leaves a footprint, burning fuel for human activity leaves greenhouse gases in the air, creating a carbon footprint. Everything we have, use, and consume, from food to clothes to transportation, are intimately linked to Hong Kong’s overall emissions figure.
According to the WWF, if everyone on Earth led the same lifestyle as that of Hong Kong people, 4.2 Earths would be required to fulfil our resource needs!
