PARIS — The
climate policies of most wealthy
countries and many high-emitting emerging economies are in line with global
heating far beyond the safer 1.5°C limit reaffirmed at UN climate talks last
month, a new analysis found Tuesday.

Even after countries raised their ambitions to cut
emissions of greenhouse gases in the last 18 months, the Paris Equity Check
assessment found that the US,
Canada, Australia, and the EU are working off
plans that could see warming between 2.1°C and 3.4°C.
The policies of emerging nations including China,
Russia, Saudi Arabia, and Turkey are even worse — implying catastrophic 5°C
heating by the end of the century.
In contrast, most of the world’s poorest countries
are on course to stay within the 1.5°C limit, according to the assessment,
which is based on peer reviewed methodology and looks at the ambition of
countries’ climate targets published up to November this year.
But researchers warned that poorer nations would
need financial support from richer countries to maintain low-emissions
development beyond 2030.
“The challenge for the global south is to stay green
beyond 2030,” said Yann Robiou de Pont, lead researcher at Paris Equity Check.
Countries have agreed to a goal to limit average
warming to 1.5°C from pre-industrial levels, which scientists say is a safer
guardrail to avoid the most dangerous impacts of climate change.
Barely 1.2°C of warming to date has unleashed a
crescendo of deadly and costly extreme weather, from heat waves and drought to
flooding and tropical storms made more destructive by rising seas.
Currently, the world is heading for around 2.5°C
under current commitments and plans.
The Paris Equity Check researchers produced online
interactive maps of the equity of countries’ climate plans, as well as another
on the warming implied by their pledges that uses peer-reviewed research updated
in early November and analysis from the group Climate Action Tracker.
Henry Kokofu, special envoy from
Ghana, which holds
the presidency of the Climate Vulnerable Forum group of countries
disproportionately affected by warming, said major polluters “must deliver and
do their fair-share to slash pollution levels this decade” — as well as support
developing nations hit by increasing impacts.
“Paris Equity Check shows who they are and the
additional effort they need to make in order to avoid catastrophic global
damage,” he said in a press statement.
