In the upcoming year, global fossil carbon dioxide (CO?) emissions are projected to witness a 1.1% increase, reaching a record 36.8 billion tonnes, as highlighted in the 18th annual report from the Global Carbon Project. Fossil CO? encompasses emissions from the combustion of fossil fuels (coal, oil, and gas) and cement production. When considering CO? emissions and removals resulting from land-use changes, such as deforestation and reforestation, human activities are anticipated to release a total of 40.9 billion tonnes of CO? in 2023.
Despite the world’s vegetation and oceans continuing to absorb approximately half of all CO? emissions, the remainder accumulates in the atmosphere, contributing to the escalating global warming trend. At the current emission rates, the remaining carbon budget for a 50% chance to limit temperature rise to 1.5°C is projected to be surpassed in seven years. Additionally, the budget for a 1.7°C limit is expected to be exceeded within 15 years. This underscores the critical urgency of implementing measures to curtail emissions, emphasizing the need for immediate and effective action to address the pressing challenges posed by climate change.
