We emit a lot of CO2

In one year the world emits 29 billion tons of CO2. That many tons could form a giant “CO2 cube” measuring 25 km on each side. By 2030, our emissions of CO2 could rise to 40 billion tons…

It’s not only about CO2

There are many other, and stronger, greenhouse gases than CO2. By 2030, all these emissions could grow by 34 percent - or what would correspond to a total of 57 billion tons of CO2.

Where does it come from?

Besides the burning of fossil fuels for energy and transportation, deforestation is a major source of CO2 emissions. Why? Because the CO2 that trees absorb and store is released into the atmosphere…

Deforestation is a major factor

…deforestation is responsible for more greenhouse gas emissions than all the world’s cars, trucks, planes and ships combined.

What about 'cap and trade'?

One of the solutions put forward by governments is CO2 emissions trading (also known as 'cap and trade'). This is not a perfect solution as this video illustrates.
