Understanding Degrowth Strategies for Climate Change Mitigation

In recent years, the discussion around tackling climate change has evolved to consider the concept of “degrowth.” This notion involves reducing production and consumption growth in high-income countries as a strategy to address the environmental pressures and challenges posed by climate change. The idea behind degrowth is to prioritize reducing unnecessary forms of production and consumption in a democratically planned manner, with the aim of enhancing equity and human well-being while alleviating the impact on the environment. A new study led by Jarmo Kikstra, a research scholar in the IIASA Energy, Climate, and Environment Program, delves into the potential of degrowth strategies in contributing to ambitious climate mitigation goals.

Examining the Feasibility of Degrowth in High-Income Countries

The study conducted by Kikstra and his colleagues focuses on assessing whether degrowth could play a significant role in enabling ambitious climate mitigation efforts. While traditional economic models have often assumed perpetual growth as a key driver of progress, the researchers explore alternative scenarios that involve no growth or even a reduction in consumption per capita. By utilizing the MESSAGEix integrated assessment model, the study examines various scenarios, including those that project reduced or zero growth, to understand the implications of such strategies on emissions reduction targets.

The research team specifically looks at Australia as a case study—a high-income country with high resource consumption patterns. By comparing degrowth scenarios to the commonly used Shared Socioeconomic Pathway (SSP) framework, which assumes GDP growth across all regions and time frames, the study sheds light on the potential benefits of pursuing degrowth strategies in the context of climate mitigation.

Implications of Reduced Consumption on Climate Mitigation

The findings of the study suggest that implementing degrowth strategies, characterized by reduced or zero growth in high-income countries like Australia, could lead to faster emissions reductions than the most ambitious scenarios outlined in the IPCC Sixth Assessment Report. By curbing energy demand and reducing GDP per capita, the feasibility of achieving climate targets is enhanced by lessening the need for extensive upscaling of renewable energy sources like solar and wind. However, the study emphasizes that even in a scenario of halted economic growth, significant investments in renewable energy infrastructure are necessary to meet climate objectives.

Moreover, the research highlights the complex interplay between reduced energy availability and the maintenance of decent living standards for all. It underscores the trade-offs between economic growth and inequality reduction, illustrating the potential pathways for meeting both human needs and climate goals. Additionally, the study emphasizes the need for further analysis to better understand the sociocultural and economic dynamics of transitioning towards a degrowth scenario in the real world.

Challenges and Opportunities for Implementing Degrowth Strategies

While the concept of degrowth presents a compelling alternative to traditional growth-oriented economic models, transitioning to such a paradigm poses several challenges. Implementing degrowth strategies requires a fundamental shift in policy frameworks and societal norms to prioritize sustainability and equity over continuous economic expansion. The study underscores the importance of exploring new research avenues to model and assess the feasibility of degrowth scenarios effectively.

The research led by Jarmo Kikstra and his team highlights the potential of degrowth strategies in enabling ambitious climate mitigation efforts in high-income countries. By reevaluating the role of production and consumption growth in addressing climate change, the study opens up new avenues for exploring sustainable pathways that prioritize environmental sustainability, equity, and human well-being. Further research and collaborative efforts are essential to unravel the intricate dynamics of transitioning towards a degrowth-oriented future and achieving a more sustainable and resilient society in the face of climate change.
