Professor Sonia Seneviratne:

To return to the target of net zero emissions by 2050, there is a scenario where there is almost no carbon captured in storage and, therefore, all the negative emissions are removed by afforestation. There are also scenarios where the carbon capture is in storage, which is a more technologically advanced development we do not have at the moment. This matter is under discussion in Switzerland, where a company is working on carbon capture although it does not yet do the storage part. When we talk about the responsibility of developed countries, we must also bear in mind the responsibility to work on solutions. One possibility is carbon capture and storage while another is more renewable energies, which we did not speak about much, such as wind energy and so on. We should also consider research and development to find new solutions.
