The area where I like to work on is home as that mean people can use less eletricity and that will help a lot as almost everyone can do that and it will make a big diference. There are about 8 million people on the planet so every home or person that uses it less can help.
A different idea connected to this, is to eat less hot oven food as they use gas and other things wich will not help the planet and people can eat things like bread and things that go in a sandwich just like cold things.
Here are some ideas on what you can do for carbon emissions :
1: Properly insulate your home
2: maintain your heating and cooling system
3: Replace incandescent light bulbs with compact fluorescent (CFL); light bulbs
Walk or ride your bike in order to avoid carbon emissions completely. Carpooling and public transportation drastically reduce CO2.
Electric cars still have carbon emissions because they’re usually charged with electricity created by the burning of fossil fuels; however, their MPG equivalents (MPGe’s) are typically much higher than conventional and hybrid cars. In some situations, electric cars like the Nissan Leaf are essentially free.
I hope this helped you to be more climate change friendly
