Green Truths
Paper shopping bags are better than plastic ones

Cause
Making a paper bag uses 4 times as much as making a plastic bag and up to 3 times the amount of water than making a plastic bag. It also produces more greenhouse gas.
Solution
Take a reusable bag when you go shopping.
Green Truths
Cause
Devices in stand-by mode still use power, and older devices in this mode can use even more, because electricity continues to leak from the devices, even when it is turned “off”.
Solution
Remove the plug from the power supply of your appliance.
When you turn off a device, it stops using power

Green Truths
Cause
Local produce might have used more energy and produced more greenhouse gases than produce grown a long way away — even taking into account its transport.
Eating local food is good for the environment

Green Truths
Cause
If you spend more than 8 minutes in a shower, you’ll use as much water as in a bath – about 50 litres of water.
Solution
Keep your shower time as short as possible.
It’s better to take a shower than a bath
