Globalizing Carbon Lock-In

The carbon lock-in concept has gained more attention as China’s rapid
industrial economic development has progressed. The concern is that if China pursues the same fossil-fuel driven economic development models of established industrial counties, building out extensive automobile-based infrastructures and fossil-fuel powered energy systems, they will lock-in persistent and growing

Recent studies by
Steven J. Davis and co-authors have quantified the future emissions that can be expected to be produced by current energy infrastructure and the magnitude of lock-in related to power plants being built each year in China and elsewhere.
