The bioeconomy can mitigate climate change

INTERNATIONAL scientists are calling for a global paradigm change to mitigate the consequences of climate change and to adapt to inescapable climate change outcomes.

Strengthened cross-sectoral and international collaboration of biosciences and economic actors would be necessary, supported by all states worldwide.

In a statement for the science journal Nature, the three chairs of the International Advisory Council on Global Bioeconomy (IACGB) reference the current Assessment Report of the Intergovernmental Panel on Climate Change which, for the first time, highlights the value of a biological contribution to the economy.

The bioeconomy will enhance coordinated action against climate change in all areas of life, according to the three chairs: Prof Dr Christine Lang (Germany), Dr Julius Ecuru (Kenya) and Dr Elspeth MacRae (New Zealand).

They name, among others, agriculture, food, regenerative mining, manufacturing, energy, healthcare, information and communications technologies, transport and housing. In all of these sectors, the bioeconomy – ie, the economic use of biological resources and processes – would have a positive impact on the climate and environment.

We call on global policymakers to encourage research and development, and international cross-sectoral bioeconomic collaboration. Such policies will provide a strategic pathway to sustainable and regenerative development, as well as engage global public and private stakeholders in responding to climate change.

In view of the United Nations climate change meeting, the Con-ference of Parties (COP27) which began yesterday in Sharm el- Sheikh, Egypt, the IACGB advocates for wider recognition of the bioeconomy as an integral part of international climate action and to elevate its overarching role in mitigating and adapting to climate change.

In a message to summit’s delegates, the scientists mention, among others, the opportunity to achieve a low-carbon emissions economy. Biological processes could be used in decarbonisation efforts like carbon capture and storage, or the recycling of fossil-based materials, or to improve energy efficiency.

In addition, the bioeconomy might help to better mobilise people to engage in actions which protect the climate, such as urban greening, biodiversity conservation and responsible consumption.


The IACGB is an independent think tank consisting of 40 high-level bioeconomy leaders and experts from all hemispheres that aim aims to develop a sustainable and circular economic system.
