Bioeconomy

Protecting the global climate is an undertaking that presents both industry and society with a major task. It will not be possible to achieve the climate targets simply by limiting global emissions, by saving carbon dioxide (CO2). This is because there will continue to be unavoidable CO2 emissions that will nevertheless have to be compensated.
