Decoupling economic growth from energy consumption: Review of global trends and policy implications

As the climate crisis on a global scale worsens, the need to reconcile the growth of the economy and environmental sustainability has become a defining challenge of the 21st century. At the heart of this discourse is decoupling, alleviating the negative footprint impacts of economic activity without endangering development objectives. This review article offers a comprehensive synthesis of global experiences with both relative and absolute decoupling, with a focus on the underlying theoretical foundations, empirical patterns, and policy mechanisms that characterize the pursuit of sustainable growth. Based on cross-country comparisons and detailed case studies, we explore how members of diverse income groups manage the balance between economic development and environmental responsibility. Developed countries now show absolute decoupling more and more, supported by technological innovation, structural economic transformation, and strong policy frameworks. On the other hand, relative decoupling is evident for a middle-income economy because the economy has recorded high growth while making modest gains in energy efficiency and emissions control. Low-income countries, on the other hand, tend to be tightly coupled, dogged by dependence on fossil fuels, weak institutions, and weak access to clean technologies. The review outlines major drivers of climate action, including carbon pricing, investments in renewable energy, urbanization, and quality of governance, along with persistent impediments, like a shortage of infrastructure, policy inertia, and lack of capital. In addition, the article defines new emerging research gaps and highlights the need for sector-specific analysis, behavioral insights, and equitable policy design with just transition in mind.
