Researchers project that the amount of carbon dioxide emissions from fossil fuel use will rise 1.1 percent in 2023 from last year, marking a record high.

The Global Carbon Project released a report on Tuesday at the COP28 climate change conference in Dubai. The group includes researchers from various countries including Japan.

The report said that if current levels of CO2 emissions persist, there is a 50 percent chance that the rise in average global temperatures will breach the Paris Agreement threshold of 1.5 degrees Celsius within seven years.

It said 36.8 billion tons of CO2 will be emitted in 2023 by burning fossil fuels such as coal and oil.

The group said coal emissions will account for 41 percent of the total, rising 1.1 percent from last year.

It said emissions in the European Union and the United States will decrease from 2022, but will increase in India by 8.2 percent and in China by 4 percent.

At COP28, European Union and island nations are calling for the need to phase out the use of fossil fuel, but some countries are strongly opposed.
