"This weekend, the world’s major economies will convene in Delhi for the G20
summit. On the table will be the common goal of limiting global temperature
rise as climate chaos becomes ever more evident.
When we talk about limiting climate change, we’re really talking about the
global carbon budget set by the Intergovernmental Panel on Climate Change.
Basically, we have a two-thirds chance of holding global heating to 1.5℃ if we
keep future emissions under 400 gigatonnes of carbon dioxide. At current
emission rates, we’ve got just under five years left before we blow through
As our new research shows, getting to net zero isn’t going to be the same in
each country. There are commonalities – halting new fossil fuel projects and
funding renewables, storage and energy efficiency. But there will be
significant differences in how manufacturing giants like China zero out
emissions compared to India or Australia.
And then there’s the question of fairness. Some countries have emitted vastly
more than others. If we divide up the remaining carbon budget while taking
historic emissions into account, we find countries like America, France,
Germany, Saudi Arabia, Japan and Australia have already gone past their fair
Meanwhile, countries which have industrialised later like Mexico, China,
Argentina, Turkey, India and Indonesia are sitting below their fair carbon
