LONDON: Projects in development will remove only a fraction of the amount of carbon dioxide (CO2) from the air that needs extracting by 2025 to meet the global Paris climate target and avert catastrophic warming, a report said on Wednesday.
More than 190 countries have signed the Paris agreement designed to limit global warming to 1.5 degrees Celsius, but even with pledges of big reductions in emissions many scientists believe removal technologies will be needed to meet the goal.
“Without action to deliver 1 Gigatonne (Gt) of negative emissions globally by 2025, keeping global warming within the Paris Agreement target of 1.5°C cannot be achieved,” said the report by the Coalition for Negative Emissions (CNE), and consultancy firm McKinsey.
It said countries will need to remove a billion tonnes of CO2 from the atmosphere by 2025, if the Paris target is to be met, and more than one billion tonnes annually thereafter.
The current pipeline of projects in development could remove only around 150 million tonnes of CO2 by 2025, well short of what’s needed, the report said.
Negative emission projects include bioenergy with technology to capture and storage carbon emissions, technology to directly capture and store emissions from the air and natural climate solutions such afforestation.
Currently removal technology is expensive and while many countries around the world have initiatives in place to put a price on CO2 emissions, the prices are far too low to incentivise new projects.
The report said scaling up the technology would lead to lower costs, with a likely average cost of 30-100 pounds($41-138) per tonne of CO2 removed by 2050.
Will Gardiner, CEO of coalition member Drax, which is seeking to develop an emissions negative power plant using biomass and carbon capture, said countries could help to pay for the technology by awarding tax credits for each tonne of CO2 removed.
Other members of the CNE, which includes over 20 companies, investors and trade associations, include Bank of America and the Confederation of British Industry (CBI).
