Scientists, world leaders and officials have all gathered in Copenhagen in Denmark for what's been described as the most important meeting in the world.
Over the next two weeks, Newsround's Leah will be taking a closer look at the effects of global warming and what we can all do to help the environment.
"All eyes are on Copenhagen for the next 12 days where hundreds of scientists, officials and world leaders are getting together to bash out a deal to help save the planet. It's being called one of the most important meetings in the world.
Many scientists agree that burning too much coal and oil is causing life threatening changes to the environment, like floods in Bangladesh and the polar ice caps melting.
Although the conference started on Monday the big leaders like Barack Obama and Gordon Brown won't arrive until next week.
But Newsround's not heading to Copenhagen to cover the meeting for you because we're thinking about our carbon footprint.
Leah with a smart meter
I did a bit of digging and found out if I travelled by plane from London to the Danish capital I would've created double the amount of carbon dioxide I'd normally produce in a week, in just one flight.
So instead, I'm trying my hand at being carbon neutral and I'll be showing you around my home to find ways I can cut back on the energy I use.
Things like switching off lights and TVs and spending less time in the shower too! The Newsround studios are even getting the once over to see how energy efficient they are.

And pupils in Durham will be showing me around their environmentally friendly school.
It's going to be a really busy week so I'm going to keep a diary keeping you up to date on all the things I'm doing to lower my carbon footprint and help do my bit to be kinder to the earth."
