Abstract
Climate change is an urgent problem, and sustainability transitions must therefore accelerate to mitigate its worst impacts. Recognising that projects function as crucial vectors of change and are essential for delivering these transitions, enhancing their effectiveness and maximising their outcomes emerges as a practical way to speed up the process. However, there is first a need to identify what influences projects that delivers transition. Thus, this systematic literature review, undertaken as part of a PhD study, aims to identify the external factors influencing projects that contribute to sustainability transitions. As a developmental paper, the review remains in its third screening phase owing to a large dataset and the relatively new nature of this research field.
