Furthermore, if public procurement were to discriminate in favour of environmental sustainability (or pro-poor inclusion), in the absence of verification in Ethiopia to prove the sustainability of supplies to agreed standards, this might open the door to corruption. However, there are examples on which to build an inclusive green procurement programme: the Protection of Basic Services (PBS) programme supported by the World Bank positively discriminates in favour of the poor. But business and civil society involvement is needed to test new green solutions in Ethiopian field and livelihood conditions.
