Global carbon dioxide emissions from all human activities remain at record highs in 2022, and fossil fuel emissions have risen above pre-pandemic levels, according to a new analysis by an international body of scientists.
The analysis, by the Global Carbon Project, calculates Earth’s “carbon budget”, which is how much CO₂ humans have released, and how much has been removed from the atmosphere by the oceans and land ecosystems. From there, we calculate how much carbon can still be emitted into the atmosphere before Earth exceeds the crucial 1.5℃ global warming threshold.
This year, the world is projected to emit 40.6 billion tonnes of CO₂ from all human activities, leaving 380 billion tonnes of CO₂ as the remaining carbon budget. This amount of emissions is disastrous for the climate – at current levels, there is a 50% chance the planet will reach the 1.5℃ global average temperature rise in just nine years.
