More attention should be paid to blue carbon, which refers to the carbon captured by the world’s ocean and coastal ecosystems,
to address the challenges of carbon neutrality and climate change facing humanity, proposed a South Korean scientist.

“The amount of carbon dioxide absorbed annually by Korean mudflats, which cover an area of about 2,489 square kilometers,
reaches a maximum of 480,000 tons,” said Khim Jong-seong, a professor at the School of Earth and Environmental Sciences at Seoul National University.
“This is equivalent to the emissions from about 200,000 cars every year.”

Khim further explained that this amount is also equivalent to the amount of carbon dioxide absorbed by about 73.40 million 30-year-old pine trees.
Considering the land area occupied by these trees, Khim emphasized that mudflats are a highly cost-effective carbon sink in terms of area ratio.
