Understanding GHG emissions can be challenging. We cannot actually see them accumulate. And they come from a variety of sources. It doesn’t help either that we usually talk about these emissions in big units which are hard to wrap our heads around. One megaton is a million tonnes.
So, to make it easier to understand we can ask: what Canadian sources are equivalent to one tonne of GHGs? How does it translate to the real world, and how do these sources contribute to overall emissions?
