"If nations make good on their latest promises to reduce emissions by 2030, the
planet will warm by at least 2.7℃ this century, a report by the United Nations
Environment Programme (UNEP) has found. This overshoots the crucial
internationally agreed temperature rise of 1.5℃.
Released today, just days before the international climate change summit in
Glasgow begins, UNEP’s Emissions Gap Report works out the difference between
where greenhouse emissions are projected to be in 2030 and where they should be
to avoid the worst climate change impacts.
It comes as the Morrison government yesterday officially committed to a target
of net-zero emissions by 2050. The government made no changes to its paltry
2030 target to reduce emissions by between 26% and 28% below 2005 levels, but
announced that Australia is set to beat this, and reduce emissions by up to
The UNEP report was conducted before Australia’s new 2050 target was announced,
but even with this new pledge, global pledges will undoubtedly still be short
of what’s needed.
The report found global targets for net-zero emissions by mid-century could cut
another 0.5℃ off global warming. While this is a big improvement, it will still
see temperatures rise to 2.2℃ this century. If we don’t close the global
emissions gap, what will Australia, and the rest of world, be forced to
