What are the main sources of global CO2 emissions?

The COP26 climate conference starts in 10 days time, and governments are failing to meet the scale of the challenge to stop the climate crisis.

As the world’s population has grown to around 7.8 billion people, greenhouse gas emissions have exploded. The task of creating a society in which so many people can live sustainably can seem overwhelming, but it is vital that we analyse where the majority of these emissions come from so we can think of ways to reduce their impact on the environment through global warming.
