IPCC Report on Mitigation of Climate Change
On 4th April Intergovenmental Panel on Climate Change (IPCC) released 6th Assessment Report on Mitigation of Climate Change prepared by the 3rd Working Group. We are very happy to inform you that the report was co-authored by one of our colleagues from the Centre for Climate and Energy Analysis (CAKE) – dr Jan Witajewski-Baltvilks. Our expert was a lead author for Chapter 16 that describes the role of innovations and new technologies.
The report presents a catalogue of possible emission reduction pathways in 21st c. and describes costs and benefits of different mitigation options. The description is based mostly on the projections of mathematical models, that take into account economic effects as well as constraints and possibilities of energy, transport and industrial systems. Similar tools are developed and used in our Centre for Climate and Energy Analysis (CAKE).
IPCC Report’s main findings:
- The report indicates that, under current policy scenarios, the path of global emissions would result in the growth of mean global temperature by around 3°C, comparing to the pre-industrial level. Gradual and significant strengthening of climate policies and achieving carbon neutrality at the global level by 2070s would allow us to limit global warming to 2°C. Immediate and radical emission reduction and achieving carbon neutrality by 2050s would allow us to limit warming to 1.5°C, which would be consistent with the targets set in the Paris Agreement. Such radical actions would require massive deployment of low-carbon technologies at the global scale, particularly in the sectors of energy, transport, industry and agriculture.
- The report notes also the special role of negative emissions. Limiting emissions using low-carbon technologies is no longer sufficient to stop global warming – in addition, in less than 20 years we will need to develop and deploy technologies that can remove CO2 from the atmosphere. This implies, among other things, significant investment in land use change, such as afforestation, and BECCS and DACCS technologies.
