Fig. 1: Sociotechnical barriers to decarbonization and their categorization.
From: Reviewing the 95 sociotechnical barriers to the decarbonization of buildings

a Conceptual model of carbon lock-in as an iron triangle of reinforcing barriers: incumbent technology support systems, high transaction costs, and business risks of innovation. These points sustain carbon-intensive systems and impede low-carbon transitions. b Classification of specific barriers of carbon lock-in into six categories: Cost, Fiscal, Regulatory, Statutory, Intellectual Property, and Other barriers. Adapted from Brown et al. 35.
