There are two main strands of criticism regarding economic growth, with environmental economists advocating for reduced human impact on ecosystems through measures like strict emission limits.
They believe this would lead to a decrease in the physical flow of energy and matter. Despite doubting the feasibility of sustaining traditional economic growth, these economists don't entirely reject the idea.
On the other side, we have the post-growth movement, which presents appealing arguments and concepts. It distinguishes a degrowth economy from one facing a recession, emphasizing a more sustainable approach.
In a degrowth scenario, people work fewer hours (e.g., thirty hours a week), and a basic income prevents financial hardship. Instead of frustration and unemployment, there is a focus on community support, repairing goods, and organizing in cooperative networks.
For a country to achieve climate neutrality, it must reduce energy consumption by improving house insulation, utilizing industrial heat for warmth, and favoring train transportation over trucks.
The University of Lund suggests fundamental actions for individuals, such as having fewer children, living without a car, avoiding long-haul flights, and adopting a plant-based diet to reduce carbon emissions.
Behavioral changes and sacrifices are crucial for effective climate protection. Decreasing consumption and relying on wind and solar power are highlighted in energy transition studies.
However, enforcing economic downsizing poses challenges. In emergencies like the pandemic, the state can mandate restraint without causing unrest.
But in normal times, convincing people of the urgency of the climate crisis is essential for broad support. Eco-morality, while influencing debates, also points to a potential solution: strict emission limits could allow the market to find innovative ways to reduce carbon dioxide, methane, and environmental toxins.
Yet, a significant issue with post-growth is the absence of a clear, promising alternative to the historically successful capitalist system. Addressing this gap is crucial for a sustainable economic future.
