     EXAMPLE OF FINANCIAL RESOURCES AVAILABLE TO DELIVER THE COMMITMENTS

     • It is important to keep in mind eThekwini Municipality is a developing city, in a developing country, on a develop-
       ing continent. As a result, there are a multitude of pressing aspects that need urgent attention, such as provision
       of housing, water and sanitation.

     • The development of policies, generally have low financial costs and will be covered by eThekwini Municipality.
       However, it is highly likely that prior to development of relevant policies, detailed assessments and studies will
       have to be conducted. Depending on the cost of these assessments, it might necessitate eThekwini Municipality
       approaching C40 for additional support.

     • If financial Incentives are offered to property owners, this will be covered through standard budgeting processes
       of eThekwini municipality.

     • Within that context, eThekwini Municipality has established a small team of experts within the Energy Office that
       will drive the processes at a strategic level, with critical input from Architecture Department, Planning Unit, and
       other relevant Units.
