I already do this
I will start doing
Turn my heating down by 1 degree C and wear a jumper
Only switch on appliances on at the wall when I need to use them
Take a shower instead of a bath
Wash all my clothes at 30oC, and only wash when I have a full load
Choose tap water, and when I am out and about use a reusable water bottle
Wash my vegetables and fruit in a bowl and water my plants with waste water
Eat local and seasonal fruit and vegetables, and have more vegetarian meals in my diet
Change my energy supply to a green renewable energy supplier
Walk, cycle or scoot for all short trips
Buy fewer new clothes and choose durable/second hand items rather than “fast fashion”
Choose products without plastic packaging whenever possible
