Three months ago the Glasgow Climate Pact (COP26) declared that by 2030 the world must cut total carbon dioxide emissions by 50 percent relative to the 2010 level, which was 30.4 billion tonnes. This would bring annual emissions to less than 20 billion tonnes, a level last seen more than 30 years ago.

What are the chances of that? Let’s look at the arithmetic.
