ENDA has carried out a case study that examines the technical and fina
ncial frameworks needed by a sub-Saharan country such as Senegal to co
ntribute to international greenhouse gas abatement efforts whilst at t
he same time guaranteeing its social and economic development. The stu
dy was part of the UNEP Greenhouse Gas Costing Studies. The first stag
e of the study was to make a preliminary inventory of greenhouse gas (
GHG) emissions for the base year 1988. Following this seven no regret
technical options for emission reduction were investigated and the cos
ts calculated, allowing the identification of three least-cost options
. The three least-cost options must be implemented first because of th
eir negative costs. The economic benefits of both abatement scenarios
are characterized by a negative global cost whatever the discount rate
is.
