Charting the path toward a greener world: A review of facilitating and inhibiting factors for carbon neutrality

The carbon neutrality (CN) literature has witnessed a mushrooming growth but also limited attempts to systematize the mass of evidence running in multiple directions. The consequent accumulation of fragmented insights can confuse concerned stakeholders, causing them to neglect or miss crucial discussions. Our study addresses this concern by undertaking a systematic literature review (SLR) of congruent studies to delineate the facilitating and inhibiting factors that support or impede the efficacious achievement of CN targets. Given the vastness of the extant literature, we limited our review to five sectors: manufacturing, energy, transportation, agriculture, and construction (METAC), since these are known to be among the highest contributors to emissions. Using a rigorous search and filtration protocol, we shortlisted 149 studies for inclusion in the review. Going beyond the curation of insights and identifying research gaps to suggest potential research questions for future investigations, our SLR contributes significantly by synthesizing facilitators and inhibitors from the reported evidence. At the same time, identifying stimulating forces and impeding hurdles helped us highlight areas requiring policy attention and managerial action to support the achievement of CN targets.
