Guardian Australia: The top 15 emitter countries could make deep cuts to emissions while also tripling economic output, according to the study.
The Deep Decarbonisation Pathways report, released by the UN secretary general, Ban Ki-moon, analyzed the 15 countries that account for 70% of greenhouse gases emitted into the atmosphere, which includes Australia, the US, Britain and China.
According to the report, compiled by academics from each of the countries, the 15 countries could make deep cuts to emissions while also tripling economic output.
These cuts are needed, the report notes, if the world is to avoid the “catastrophic” impact of failing to keep to the internationally agreed limit of 2C global warming on pre-industrial levels. The study concedes the world is on track to overshoot this.
A further UN report in September will set out the monetary cost of a rapid increase in renewables to cut emissions to zero.
But the newly released study plots a path that involves phasing out coal use almost entirely, shifting electricity generation to renewable sources such as solar and wind, and powering vehicles and buildings with clean electricity rather than fossil fuels such as oil and petrol.
Industrial and farming processes that can’t use such clean technology would be offset by large-scale storage of carbon in soils and trees.
