Carbon Takeback Obligation CTBO
The Carbon Takeback Obligation (CTBO) is an initiative that requires producers and importers of fossil fuels to develop methods to store a portion of the CO2 created by their activities. This proportion will increase over time. The purpose is to provide incentives for producers to keep CO2 permanently out of the atmosphere. The commitments by producers to CTBO are voluntary.
 Holding producers accountable for CO2
The CTBO policy initiative was introduced by the report ‘Carbon Takeback Obligation - A Producer Responsibility Scheme on the Way to a Climate Neutral Energy System’, published in January 2021 and written by Margriet Kuijper Consultancy, De Gemeynt and Royal HaskoningDHV.
According to Margriet Kuijper, project leader of the study: "A CTBO stipulates that the net CO2 emissions from this inevitable use of fossil fuels will go to zero in a timely manner".
CTBO is similar to incentives that have been adopted in other areas of production, where manufacturers are given the physical and financial responsibility of managing the disposal of products that contain substances that are considered harmful to human health and the environment.
 CTBO and other initiatives
It is believed that the CTBO could be paired with the Government policy of Contracts for Difference (CfDs) to produce a marketplace where companies could trade certificates of storage. It is believed that the outcome of this partnership would encourage the development of carbon capture and storage (CCS) technologies as companies are given incentives to seek to lower their costs associated with the CTBO, and could see the UK becoming a world leader in carbon trading.
The report explains, " A CTBO will generate an incentive supplementary to the effect of the emissions trading system (ETS). Businesses and sectors subject to this system are required to purchase and pay for emission rights. CCS will reduce their emissions, which means they will need fewer rights. However, they will incur expenses for CO2 capture and storage. A CTBO will create a demand for CO2 (and thus put a price on CO2) because producers and importers of fossil carbon compounds will need to reserve CO2 to be stored (CSUs). Thus, the CTBO and ETS schemes can be enforced alongside one another (as can other instruments, for that matter)."
As of 2021, CTBO is in the recommendation stage.
