When Will Net Zero Happen... Global Greenhouse Gas Emissions Increased Again Last Year

As carbon neutrality has emerged as a global issue, it has been revealed that greenhouse gas emissions last year reached the worst level ever recorded.

Carbon Footprint

According to the U.S. National Oceanic and Atmospheric Administration (NOAA), the average atmospheric carbon dioxide concentration last year was 419.3 ppm. This is 50% higher than the pre-industrial level. The concentration of carbon dioxide has been increasing for 12 consecutive years. Researchers from the University of Utah and Columbia University reported in the scientific journal Science that the current carbon dioxide concentration has reached 420 ppm, the highest level in 14 million years in Earth's history.

The methane concentration averaged 1922.6 ppb last year, which is 160% higher than the pre-industrial level. The nitrous oxide concentration was 336.7 ppb last year, an increase of 1 ppb. The nitrous oxide concentration is 25% higher than the pre-industrial level. Carbon dioxide, methane, and nitrous oxide are considered the main culprits of global warming.

NOAA emphasized, "Air pollution from fossil fuels is heating natural ecosystems such as wetlands and permafrost," adding, "Given these figures, there is still much work to be done to reduce greenhouse gases in the atmosphere."
