The results of the Global Carbon Budget 2022 are bleak. The report explains that carbon emissions are continuing to rise, and that, if this continues, it will lead to an increase in global average temperature to above the 1.5°C limit in just 9 years. This limit is significant because it indicates that climate change will reach a very destructive stage in a single decade. As the IPCC explained in the AR6 Working Group II report, published in February 2022, every small temperature increase reduces our ability to adapt to climate change.
However, this report does not demonstrate a total lack of action on climate change. Indeed, there is widespread interest in responding to climate change and there is evidence of responses from the public and private sectors, and from NGOs, community organisations and individuals. These efforts, however, are not enough. In my opinion, these voluntary efforts must be accompanied by agreements to regulate the use of fossil fuels, especially at the global level.
The Global Carbon Budget data is on a positive note, because it shows that progress on the path to zero-carbon is possible in regions such as China and the European Union. The International Energy Agency has also recently published the 2022 World Energy Outlook, which explains that renewables are still on the rise. However, data from countries such as the United States are less optimistic and show the need, once again, for a global partnership to tackle one of the biggest problems of our generation.
