What precisely are “abated” fossil fuels?
“No one is aware of,” mentioned Gerrit Hansen, a local weather coverage professional on the German Institute for Worldwide and Safety Affairs. “And that’s the trick. It’s deliberately ambiguous.”
The haziness of “unabated” is politically advantageous, because it presents a possible compromise between nations that need a right away shift to cleaner vitality and others that see themselves remaining closely depending on coal and different fossil fuels.
“
Progress may be very gradual and faltering. These services should not like vehicles – as soon as they’re constructed they’re more likely to be working previous 2050. You must be constructing at cutting-edge right this moment.

However a fuzzy definition of “abated” means nations depending on fossil fuels would possibly be capable to argue that “even a 1 per cent discount in emissions would qualify as ‘abated’,” Hansen mentioned.
“That may clearly not make any sense” for limiting local weather change, he added.
A unfastened definition dangers the world breaching 1.5 levels Celsius (2.7 Fahrenheit) of warming above pre-industrial occasions in coming years, a degree prime scientists see as a guardrail towards the worst impacts of local weather change.
Strict limits on emissions, against this, might assist preserve the 1.5C goal in attain. Fossil fuels account for about 80 per cent of world vitality use.
Which nations favour what definitions of abatement?
Governments will enter COP28 sharply divided over abatement, dates and targets for slicing dependence on fossil fuels.
A “excessive ambition coalition“, as an illustration, laid out a plan a month earlier than COP28 to “part out fossil gas manufacturing and use” solely.
The coalition, together with small island growing states comparable to Tuvalu and Grenada together with France, Kenya, Colombia and New Zealand, mentioned applied sciences to “abate” emissions solely exist at a restricted scale and can “have a minor position to play”.
Against this, fossil gas producers comparable to Saudi Arabia and Russia, summit host the UAE and coal-dependent nations comparable to India and China favour vaguer language.
A pre-summit notice by the UAE, as an illustration, sought a world “working in direction of an vitality system freed from unabated fossil fuels by mid-century, with coal being a precedence”.
Main industrialised democracies within the Group of Seven wealthy nations this yr referred to as for a “international effort to speed up the phase-out of unabated fossil fuels to realize web zero in vitality programs by 2050”.
The USA needs to part out unabated fossil fuels, whereas additionally selling carbon seize and storage (CCS) know-how.
The EU needs to part out unabated fossil fuels and obtain an vitality sector “predominantly freed from fossil fuels effectively forward of 2050”. However “predominantly” is open to interpretation and reductions might run from slightly over half to virtually 100 per cent.
Some environmental teams have expressed exasperation over what they see as a semantic fig leaf for continued dependence on fossil fuels, with an excessive amount of hope positioned in CCS.
“We’re targeted on eliminating fossil fuels altogether, with out weasel phrases,” mentioned Doug Parr, UK coverage director for Greenpeace.
Are there any definitions of “abated” and “unabated”?
A footnote in a 2023 report by the Intergovernmental Panel on Local weather Change, a bunch of scientists and governments, says abatement ought to “considerably cut back” greenhouse gasoline emissions.
It mentions “for instance, capturing 90 per cent or extra carbon dioxide from energy vegetation, or 50–80 per cent of fugitive methane emissions from vitality provide”. Methane is the principle part of pure gasoline.
Some scientists are working to pin down strict definitions.
“The time period ‘unabated’, if left unchecked and poorly outlined, might go away the interpretation of the dedication large open,” famous a 2023 working paper by scientists led by Christopher Bataille at Columbia College.
Bataille and co-authors suggest the phrase “abated” ought to solely be used when fossil gas emissions are lowered by 90-95 per cent, as an illustration with CCS or applied sciences to suck greenhouse gases from the air.
On the identical time, tighter rules ought to goal to restrict leaks of methane to close zero. Nations comparable to Turkmenistan and Russia lose huge quantities of methane to leaky infrastructure.
With individuals dealing with ever extra excessive heatwaves, storms, floods and wildfires, Bataille mentioned time is operating out to set requirements, particularly for brand spanking new coal-fired energy vegetation and different industrial services.
“Progress may be very gradual and faltering,” he advised Context. “These services should not like vehicles – as soon as they’re constructed they’re more likely to be working previous 2050. You must be constructing at cutting-edge right this moment.”
