Carbon capture and storage could unleash 86 billion tonne carbon bomb
A new analysis finds reliance on carbon capture and storage could release an extra 86 billion tonnes of greenhouse gases into the atmosphere between 2020 and 2050.
‘Unabated’ language a ploy to wedge open door on fossil fuel industry
Reliance on carbon capture and storage (CCS) could release an extra 86 billion tonnes of greenhouse gases (GHG) into the atmosphere between 2020 and 2050, finds a new analysis published today by the think tank Climate Analytics.
The report calculates the additional emissions that could result from continued fossil fuel use excused by reliance on CCS. It highlights the level of risk should the technology continue to underperform, consistent with the industry’s record. The Intergovernmental Panel on Climate Change recommends capture rates of around 95%.
If carbon capture rates only reach 50% rather than 95%, and upstream methane emissions are not reduced to low levels, this would pump 86 billion tonnes of GHG into the atmosphere – equivalent to more than double the global CO2 emissions in 2023.
Opening up ‘abated’ fossil fuels risks pushing the Paris Agreement’s 1.5°C warming limit out of reach, particularly considering the expansion of oil and gas projects presently promoted around the world.
“The term ‘abated’ is being used as a trojan horse to allow fossil fuels with dismal capture rates to count as climate action. ‘Abated’ may sound like harmless jargon, but it’s actually language deliberately engineered and heavily promoted by the oil and gas industry to create the illusion we can keep expanding fossil fuels," says report author Claire Fyson of Climate Analytics.
The report finds that discussions around ‘abatement’ are creating the false impression that CCS can enable the ongoing widespread use of fossil fuels whilst still meeting the Paris Agreement’s 1.5°C limit. However, scenarios that achieve the Paris Agreement’s 1.5°C limit in a sustainable manner show a near complete phase-out of fossil fuels by around 2050 with only a tiny amount of fossil CCS.
“We need to cut through the smoke and mirrors of “abated” fossil and keep our eyes fixed on the goal of 1.5ºC. That means slashing fossil fuel production by around 40% this decade, and a near complete phase-out of fossil fuels by around 2050,” says Dr Neil Grant of Climate Analytics.
The report was released as governments meet at the UN climate summit in Dubai today to discuss carbon management. The IEA has consistently downgraded its estimation of the role of CCS in the energy transition, assuming 38% less in its 2023 projections compared to 2021. This is due to the decrease in cost of renewable energy and the greater potential for alternatives to fossil fuels in industry.
“The false promises of ‘abated’ fossil fuels risks climate finance being funnelled to fossil projects, particularly oil and gas, and will greenwash the ‘unabatable’ emissions from their final use, which account for 90% of fossil oil and gas emissions,” added Bill Hare, CEO of Climate Analytics.

Projected warming almost unchanged for two years as governments push false solutions over climate action
Despite their promises, governments have not taken enough action to drive down warming projections, with some instead turning to false solutions such as carbon capture and storage to continue the world's reliance on fossil fuels, according to the Climate Action Tracker's annual warming update.
Oil and gas majors could have paid for their share of climate loss and damage and still earned 10 trillion USD: new report
Global climate damages from emissions associated with the top 25 oil and gas ‘carbon majors’ between 1985 and 2018 are estimated at 20 trillion USD compared to the 30 trillion USD they earned over the same period, according to a new report released today by international think tank Climate Analytics.
A 1.5˚C pathway for the Philippines power sector entirely feasible: analysis
With the right international funding and policies in place, the Philippines could transition its’ power sector to near-100% renewable energy without compromising on the costs of electricity, reducing its reliance on expensive imports of both coal and gas, and creating up to a million jobs by 2050.
State of Climate Action report finds progress lags on every measure except EV sales
Global efforts to limit warming to 1.5°C are failing across the board, with recent progress made on every indicator — except electric passenger car sales — lagging significantly behind the pace and scale that is necessary to address the climate crisis.
Governments plan to produce double the fossil fuels in 2030 than the 1.5°C warming limit allows
The Production Gap Report finds governments plan to produce around 110% more fossil fuels in 2030 than would be consistent with limiting warming to 1.5°C, and 69% more than would be consistent with 2°C.
Beetaloo fracking and Middle Arm emissions wildly underestimated: analysis
An independent analysis of the projected emissions from the Northern Territory's proposed Beetaloo Basin gas fracking project — and the associated Middle Arm LNG precinct in Darwin Harbour — has found they've been gravely underestimated, as have the availability of offsets to deal with them.
