How a Secret Vote by U.N. Scientists Legitimized Carbon Capture and Skewed Decades of Climate Policy
A ProPublica investigation says a 2005 United Nations climate report helped legitimise carbon capture and storage (CCS) despite major uncertainties about whether it could safely and permanently store emissions. The report’s consensus process, led in part by geoscientist Sally Benson, brought CCS into mainstream climate policy at a time when evidence from large-scale projects was limited.
More than 100 scientists gathered in Spain, including researchers from Shell, Chevron and Saudi Aramco, after oil-producing countries pressed for the report. Only one of three major projects had rigorously tested permanent storage: a Norwegian operation where injected carbon dioxide rose about 700 feet before shale trapped it. The investigation says the fossil fuel industry viewed CCS as a way to keep using coal, oil and gas, while critics warned it could distract from phasing out fossil fuels.
In short
- A 2005 UN report helped bring carbon capture into mainstream climate policy.
- Evidence on permanent underground storage was limited.
- Fossil fuel companies saw CCS as a way to keep burning fuels.
Steelman: both sides, in good faith
The strongest fair case each way — we don't pick a winner.
The case for
Supporters could argue that the report gave policymakers a potentially important tool for reducing emissions while energy systems still depended on fossil fuels. With limited large-scale evidence, including a Norwegian project showing that geological layers could trap injected carbon dioxide, including CCS in the policy discussion may have encouraged further research and practical testing rather than ruling it out prematurely.
The case against
Critics could argue that the report gave an uncertain technology more authority than the evidence warranted, helping make continued fossil fuel use appear compatible with climate goals. They may see the secret consensus process and fossil fuel industry participation as reasons for concern, and argue that reliance on future carbon storage could divert attention, investment and urgency from cutting fossil fuel use directly.
Explained simply
Carbon capture and storage (CCS) is a way to collect carbon dioxide from industrial sites or power stations and inject it deep underground. It is intended to keep the gas out of the atmosphere, but its safety and ability to store carbon permanently need to be assessed over time.
The United Nations’ climate science panel brings researchers together to assess evidence and inform governments’ climate policies. Its 2005 report examined CCS when large-scale experience was limited; the process included scientists from energy companies as well as other researchers.
CCS matters because it could reduce emissions from some activities, while also allowing fossil fuels to remain in use. Governments and researchers have weighed its potential against questions about storage risks, costs and whether reliance on the technology could slow other ways of cutting emissions.
