IPCC report: 43% reduction in greenhouse gas emissions by 2030 to achieve ‘Below 1.5°C’
On March 20th, IPCC(Intergovernmental Panel on Climate Change) of the United Nations released the Synthesis Report (SYR) for the Sixth Assessment Report (AR6), which summarizes the long-term outlook and measures for global warming. While national governments are striving to mitigate climate change, the report states that greenhouse gas emissions are likely to result in a temperature increase of 1.5℃ compared to the pre-industrial period (1850-1900) by 2040. In order to limit the temperature increase by 1.5℃ for the target of Paris Agreement, the report indicates to require the decrease in greenhouse gas emissions by approx. 43% from 2019 to 2030.
This is the first Synthesis Report issued in nine years. At the beginning of the report, it states that 1.1℃ of global warming has already occurred and it will be difficult to restrict the rise to below 2 ℃. It also explains that the efforts and plans of each country to mitigate the climate change are currently insufficient. The report notes that climate change risks are higher than it is evaluated in the Fifth Assessment Report.
The report says that it is required to significantly reduce greenhouse gas emissions in all industrial sectors in order to limit the temperature increase. Introduction of clean energy is proposed in the energy sector. Introduction of CCUS (Carbon dioxide Capture, Utilization and Storage) in facilities using fossil fuel is also essential for reducing emissions.
