Transition Towards A Low-carbon Society

Participation By All Citizens

According to 2019 data, we need more than 4 Earths if everyone in the world follows the lifestyle of Hong Kong people. 19 We can explore room for improvement and can do better in reducing our carbon footprint in order to combat climate change. A less wasteful and energy saving lifestyle is a “must” way to begin with.

Everything we need in daily lives has a carbon footprint and food is no exception. Food’s carbon footprint is the GHG emissions produced by growing, rearing, farming, processing, transporting, storing, cooking and disposing of the food we eat. Changing our dietary patterns (e.g. more vegetables, less meat), choosing locally grown produce, and minimising our food waste can have a big impact on our carbon footprint.

Food Waste: An Overlooked Driver of Climate Change

Globally, food wastage creates about 8% of all human-induced GHG emissions.21 We can always take small steps to curb our emissions at source by consuming food wisely, reducing and delivering surplus to those in need, shopping wisely and turning food waste into energy.

Are you aware of the relationship between your daily activities and carbon emissions? How can we facilitate you to have a better grasp of the related information?

How about you only cook the portion that you will eat, so that you can save money as well as food?
