This course is about life and death – about the ability of mankind to restrain its environmental impact in order to make the existence of future generations possible. The International Geological Congress agreed in August 2016 that we had entered the Anthropocene – a new geological age where human influence has a distinct impact on most planetary systems. Greenhouse gas emissions from human activities have already caused an increase in global average temperature by 0.8 degrees Celsius and a raise of sea-level by 20 centimeters, triggering slow but dramatic planetary-wide adjustments. Efforts have been made to try to mitigate the disaster. Several treaties have been adopted since 1992. Under the US-China Joint Announcement of 2014 and the Paris Agreement of 2015, the world’s greatest economic actors agreed to accelerate and increase domestic measures. Substantial investments are being made to induce a global transition to “green” economy, with China progressively taking the lead. Hong Kong is bound by several treaties ratified by China. Hong Kong’s Climate Change Strategy and Action Agenda was adopted in 2010 and is being implemented through laws and policies in multiple sectors. Responses to climate change are increasingly impacting all aspects of the law, domestically and internationally. But is this sufficient? Will we, as a civilization and as a species, survive our entry in the Anthropocene?
