Consuming too much meat

Meat production is a severe strain on the world's resources

Farm animals produce 13 billion tonnes of waste worldwide annually

Farm animals contribute 18 per cent of greenhouse gases, which cause global warming. This percentage is higher than the emissions from vehicles


Eat vegetarian meals several times a week

Poultry and pork are better options than beef and lamb

Consume a maximum of one portion of animal protein a day

Go for quality instead of quantity

High mileage for transporting food

A non-seasonal fruit transported by air uses 20 times the energy needed to grow a local seasonal fruit


Buy local seasonal fruits as they will have more vitamins because of the reduced transport time

Consuming too much water in plastic bottles

A large amount of energy is used during the manufacturing process

More than 13,000 pieces of plastic litter float on every square kilometre of the ocean surface

Plastics never degrade


Buy a water filter because it will save you HK$3,000 over three years

Overuse of air conditioners

Refrigerant gases emitted from air conditioners are 1,000 times more harmful than carbon dioxide

Air conditioners consume 60 per cent of all Hong Kong's electricity during summer


Set your air conditioner at 25.5 Celsius

Turn on the air conditioner just minutes before you need it - it doesn't take long to cool down a room

Turn off the air conditioner 20 minutes before you leave the room as the air will remain cool and fresh for that period

Avoid direct sunlight on the air conditioner

Make sure you clean the dust screen regularly and microseal ducts to improve energy efficiency. Poorly fitted ducts can add 25 per cent to your electricity bill
