What is carbon capture and why does it keep coming up at COP28?
The future of fossil fuels that are warming the planet are at the core of negotiations at the United Nations climate summit in Dubai
The future of fossil fuels is at the center of the United Nations climate summit in Dubai, where many activists, experts and nations are calling for an agreement to phase out the oil, gas and coal responsible for warming the planet. On the other side: energy companies and oil-rich nations with plans to keep drilling well into the future.
In the background of those discussions are carbon capture and carbon removal, technologies most, if not all, producers are counting on to meet their pledges to get to net-zero emissions. Skeptics worry the technology is being oversold to allow the industry to maintain the status quo.
“The industry needs to commit to genuinely helping the world meet its energy needs and climate goals – which means letting go of the illusion that implausibly large amounts of carbon capture are the solution,” International Energy Agency Executive Director Fatih Birol said before the start of talks.
WHAT EXACTLY IS CARBON CAPTURE?
Lots of industrial facilities like coal-fired power plants and ethanol plants produce carbon dioxide. To stop those planet-warming emissions from reaching the atmosphere, businesses can install equipment to separate that gas from all the other gases coming out of the smokestack, and transport it to where it can be permanently stored underground. And even for industries trying to reduce emissions, some are likely to always produce some carbon, like cement manufacturers that use a chemical process that releases CO2.
“We call that a mitigation technology, a way to stop the increased concentrations of CO2 in the atmosphere,” said Karl Hausker, an expert
