Piercing through the Gridlocks addresses behavioural barriers to sustainable transport and waste management through evidence-based research and targeted interventions. A comprehensive public participation survey maps citizens' habits, barriers, and preferences — forming the basis for co-designed behaviour change initiatives across both sectors. Year 1 delivered strong early results. The survey received 1,800+ responses against a target of 1,000. A waste-sorting intervention with foreign residents achieved an 85% improvement in sorting rates within one month. A student mobility intervention enrolled 468 participants, with incentivised groups showing noticeably higher sustainable transport use than the control group. Despite staff turnover and local government changes disrupting survey distribution, the project maintained momentum and delivered across all major workstreams.
