INTERNATIONAL ENERGY AGENCY CO2 EMISSIONS REPORT 2023
by the Numbers:
2023 brought significant shifts in global CO2 emissions, with numbers telling a story of both challenge and opportunity in the face of climate change. Here's a closer look at the year's key statistical highlights:
Global Increase: Energy-related CO2 emissions rose by 1.1%, adding approximately 410 million tonnes (Mt) to reach a record high of 37.4 billion tonnes (Gt).
Coal's Impact: Over 65% of the increase in emissions in 2023 was due to coal, emphasizing the urgent need for energy transition away from fossil fuels.
Hydropower Shortfall: A global shortfall in hydropower generation, primarily due to droughts, contributed an additional 170 Mt to emissions. This shortfall underscored the vulnerability of our energy systems to climate variability.
Clean Energy's Role: The growing deployment of solar PV, wind, nuclear, heat pumps, and electric cars since 2019 helped avoid a tripling of emissions growth. Without these technologies, the increase in emissions would have been much more significant.
Advanced Economies: In these regions, GDP grew by 1.7%, but emissions fell by 4.5%, marking a record decline outside of a recessionary period. This decline brought emissions back to levels last seen fifty years ago, with coal demand in the G7 back to levels around 1900.
China's Emissions: China saw the largest global increase in emissions, approximately 565 Mt in 2023. Despite this, China continues to lead in clean energy additions. One-third of its emissions growth in 2023 was attributed to a historically bad hydro year.
India's Growth: In India, strong GDP growth resulted in an emissions increase of around 190 Mt. A weak monsoon significantly cut hydro production, contributing to a quarter of the total emissions increase in the country.
These numbers above reflect the complex interplay between economic growth, energy production, and climate policies. They underscore the importance of accelerating the global energy transition towards more sustainable and renewable sources to mitigate the impacts.
