The CPD’s Green Cities Initiative was set up to better understand the drivers of air and plastic pollution in Bangladesh’s cities and develop workable policy solutions to air and plastic pollution. Since its establishment, the Green Cities Initiative has brought together scientific evidence and economic analysis, producing a series of reports, policy briefs and events that have improved understanding of the problem among policymakers, journalists and members of the academic community. This report details much of the work so far to build up a useful body of evidence for those developing policy in Bangladesh.
