A new UN report that takes stock of climate action with respect to the targets
outlined in the Paris Agreement
has shone new light on how we continue to come up short. Among the key
points are that, after stabilizing for three years, global carbon
emissions are again on the rise and have now reached record levels,
prompting calls for further action in efforts to close the gap.
The
UN Environment's Emissions Gap Report is the body's definitive annual
assessment on the void between projected carbon emissions in the year
2030, and what are seen as the levels required to keep global warming to
2° C (3.6° F) above pre-industrial levels, a threshold experts consider
the bare minimum to avoid the worst affects of climate change.
Prepared by an international team of scientists, the report's release comes hot on the heels of this week's US government Fourth National Climate Assessment, along with the Intergovernmental Panel on Climate Change's
(IPCC) special report released in October. Both of these offered a
rather grim outlook on the health of the planet, and the 2018 Emissions
Gap Report does little to buck the trend.
"If
the IPCC report represented a global fire alarm, this report is the
arson investigation," says UN Environment Deputy Executive Director
Joyce Msuya. "The science is clear; for all the ambitious climate action
we've seen – governments need to move faster and with greater urgency.
We're feeding this fire while the means to extinguish it are within
reach."
According
to the team's analysis, current trends will likely lead to global
warming of around 3° C (5.4 F) by the end of the century, from which
point temperatures will continue to rise. Key to this is that after
stalling for three years, global emissions reached historic levels in
2017 and are showing no signs of abating. The authors claim the
emissions gap is now larger than ever, and that only 57 countries are on
track to reach peak emissions (and then begin to decrease) by 2030.
But
it's not all doom and gloom. The report also offers some insights into
how the planet can be set on a healthier path, pointing to an increasing
commitment to climate action from governments around the world, as well
as education institutions and the private sector. With that said, the
authors make no bones about the task at hand, concluding that nations
around the world must triple their current efforts in order to meet the
2° C target.
"When
governments embrace fiscal policy measures to subsidize low-emission
alternatives and tax fossil fuels, they can stimulate the right
investments in the energy sector and significantly reduce carbon
emissions." said Jian Liu, UN Environment's Chief Scientist.
"Thankfully, the potential of using fiscal policy as an incentive is
increasingly recognized, with 51 carbon pricing initiatives now in place
or scheduled, covering roughly 15 percent of global emissions. If all
fossil fuel subsidies were phased out, global carbon emissions could be
reduced by up to 10 percent by 2030. Setting the right carbon price is
also essential. At US$70 per ton of CO2, emission reductions of up to 40
percent are possible in some countries."
