As we review our progress in fighting climate change, we look back at global CO2 emissions in 2023 as a key benchmark in that struggle. The story is one of bad news with a silver lining.
The latest data indicates that global energy-related CO2 emissions have grown by 1.1%, an increase of 410 million tons (Mt), culminating in a new record high of 37.4 billion tonnes (Gt). Coal’s resurgence has contributed to more than 65% of this increase, emphasizing the urgency for industry to increase efficiency and productivity in energy consumption and greenhouse gas mitigation.
CO2 Emissions could have been much higher
The unexpected global shortfall in hydropower generation, primarily due to widespread droughts, has resulted in an additional 170 Mt of CO2 emissions. In the absence of this hydropower deficit, it is projected that emissions from the global electricity sector would have declined in 2023. The overall increase in energy-related emissions from 2019 to 2023 was approximately 900 Mt. However, the acceleration in the deployment of key clean energy technologies, such as solar PV, wind, nuclear, heat pumps, and electric vehicles since 2019, has averted a potential tripling of emissions growth. This clean energy progress is a testament to a structural slowdown in emissions, with an average annual growth rate of just over 0.5% over the past decade—the slowest since the Great Depression.
GDP Growth without CO2 Emissions Increase
In advanced economies, we observe a dichotomy where GDP grew by 1.7%, yet emissions saw a record decline of 4.5%, the largest drop outside of a recessionary period. Emissions have now reverted to levels seen half a century ago, with coal demand within the G7 reaching figures comparable to those of the year 1900. The decline in 2023 is attributed to both structural changes, such as robust renewable energy deployment and coal-to-gas switching in the US, and cyclical factors like subdued industrial production in certain regions and milder weather conditions.
China’s Hydroelectricity Shortfall
China witnessed the largest emissions increase globally at 565 Mt in 2023, perpetuating its pattern of emissions-intensive growth post-pandemic. Despite this, China remains at the forefront of global clean energy additions. A significant hydroelectricity shortfall, one of the worst in history, accounted for about one-third of China’s emissions increase in 2023. Currently, per capita emissions in China surpass those of advanced economies by 15%.
India Impacted by Lower Rainfall
In India, robust GDP growth spurred an emissions surge of approximately 190 Mt. A weak monsoon season exacerbated the situation by inflating electricity demand and constraining hydroelectric production, contributing to about one-quarter of the total increase in India’s emissions for 2023. Still, India’s per capita emissions continue to be substantially lower than the global average.
Fossil Fuel Peak Demand
Combatting climate change and transitioning towards renewable energy is imperative. Reports from the International Energy Agency (IEA) suggest that the momentum behind clean energy transitions could lead to a peak in global demand for fossil fuels before 2030. This pivotal change in energy consumption patterns marks a potential turning point in mitigating our environmental footprint, but achieving this requires unwavering commitment and strategic action.
CO2 Emissions in 2023 and the Paris Agreement
The rise in CO2 emissions in 2023 presents a formidable challenge to achieving the climate objectives outlined in the Paris Agreement. Staying within the desired limit of 1.5 degrees Celsius of global warming above pre-industrial levels is becoming increasingly difficult. This necessitates immediate and collaborative efforts to escalate clean energy investments and lessen fossil fuel reliance.
Encouragingly, the United States has experienced a 3% decrease in emissions, primarily due to the sustained reduction in coal usage. This demonstrates that strategic shifts in energy policies and industrial practices can have a significant impact. If the United States industry leaders continue their alignment with these global efforts, championing energy optimization and waste reduction, the USA is expected to further decrease its CO2 emissions in the future.
Reducing CO2 is Good for Business
Achieving a carbon-neutral future is not solely about embracing renewable energy; it also involves applying lean principles to enhance operational efficiency and profitability. Industry’s future dedication to minimizing waste and enhancing safety is in harmony with the broader objective of establishing a sustainable and resilient energy infrastructure.
The focus on renewable energy, combined with the efficiency-driven ethos, will be instrumental in decreasing CO2 emissions. The journey towards a greener future is steered by the core principles of lean management and the collective commitment to clean energy adoption.
