COP28, with carbon storage at risk of 'greenhouse gas bomb' - Lavoro & Sviluppo

2023-12-05T14:16:25.582Z

Highlights: Carbon capture and storage (CCS) "could release an additional 86 billion tonnes of greenhouse gases into the atmosphere between 2020 and 2050," according to a new analysis. The report calculates the additional emissions that could result from the continued use of fossil fuels justified by the choice of CCS. The Intergovernmental Panel on Climate Change (IPCC) recommends carbon capture rates of around 95%. If, on the other hand, it reaches only 50% and methane emissions are reduced upstream to low levels, the report says, the emissions would be equivalent to more than double global CO2 emissions in 2023.

Carbon capture and storage (CCS) "could release an additional 86 billion tonnes of greenhouse gases into the atmosphere between 2020 and 2050," according to a new analysis published today by the think tank Climate Analytics.
The report calculates the additional emissions that could result from the continued use of fossil fuels justified by the choice of CCS. The Intergovernmental Panel on Climate Change (IPCC) recommends carbon capture rates of around 95%. If, on the other hand, it reaches only 50% and methane emissions are reduced upstream to low levels, 86 billion tonnes of greenhouse gases would be released into the atmosphere, equivalent to more than double global CO2 emissions in 2023.
Opening up to "abated" fossil fuels (whose emissions are reduced through CCS technologies) risks pushing the Paris Agreement's 1.5-degree warming limit out of reach, particularly given the expansion of oil and gas projects currently being promoted around the world, the report said as governments meet today at the UN climate summit in Dubai to discuss carbon management.
The International Energy Agency has consistently revised downwards its estimate of the role of CCS in the energy transition, assuming 38% less in its projections for 2023 than in 2021. This is due to the falling cost of renewable energy and the greater potential for alternatives to fossil fuels in industry, recalls the think tank Climate Analytics.
