Carbon lock-in
Carbon lock-in refers to the self-perpetuating inertia created by large fossil fuel-based energy systems that inhibits public and private efforts to introduce alternative energy technologies. Related to the concept of technological lock-in, the concept is most used in relation to the challenge of altering the current energy infrastructure to respond to global climate change.
The concept and term was coined by Gregory C. Unruh in a 1999 Fletcher School, Tufts University doctoral thesis entitled "Escaping Carbon Lock-In." It has since gained popularity in climate change policy discussions, especially those focused on preventing the globalization of carbon lock-in to rapidly industrializing countries like China and India.
The source of carbon lock-in inertia in energy systems arises from the co-evolution of large interdependent technological networks and the social institutions and cultural practices that support and benefit from system growth. The growth of the system is fostered by increasing returns to scale.
According to Unruh:
…industrial economies have been locked into fossil fuel-based energy systems through a process of technological and institutional co-evolution driven by path-dependent increasing returns to scale. It is asserted that this condition, termed carbon lock-in, creates persistent market and policy failures that can inhibit the diffusion of carbon-saving technologies despite their apparent environmental and economic advantages.
— Gregory C. Unruh, Understanding carbon lock-in (2000)
The concept emerged in response to what is termed the "climate policy paradox," which recognizes that there is substantial scientific consensus that climate change is a real and present threat to humans and other species uniquely adapted to current climatic conditions. Similarly there is evidence that technologies exist which can lower the carbon intensity of economic activity in a cost-effective manner, including energy efficiency innovations as well as some renewable energy applications. The existence of these apparent "win-win" no-regrets opportunities for society to act on climate concerns creates a paradox. If such technologies exist, and they are cost effective and help minimize climate-forcing emissions, why aren't they diffusing more rapidly? The conjecture is that industrial economies have become locked into fossil fuel technologies by past investments and policy decisions, the effects of positive feedback on increasing returns, and the economic growth of energy infrastructure.
Carbon lock-in emerges over time as energy and economic development in industrialized countries has proceeded. The carbon lock-in framework builds hierarchically from individual technological artifacts, usually manufactured by for-profit organizations, to technological systems of interdependent artifacts. As these systems grow, they begin to have important societal implications drawing in government regulation of the system's growth and development. The government's involvement with system management, be it for safety, universal service or other national interests, institutionalizes the system and signals the emergence of a techno-institutional complex.
