There are many things you can do to reduce to help such as reducing your own carbon emissions:
Save energy, not waste it! Switch electonics off when they aren’t in use and not leaving them on standby can make a huge difference.
Switching to renewable energy suppliers.
Where possible recycle everything you no longer want or need and buy second hand items.
Use public transport, walk or cycle as opposed to going everywhere by car.
