The increase in the number of vehicles has resulted in a continuous growth in the consumption of fuel in
Cameroon; and has contributed to the increase of Cameroon’s GHG emissions. GHG emissions inventory from
the road transport sector during the period 1995-2008 reported in this paper was conducted following the
recommendations of the UNFCCC. The study also includes the indicators that are the major contributors to
Cameroon’s GHG emissions. The direct GHG emissions are calculated on a bottom-up Tier 2 methodology
described by the IPCC guidelines and Kaya’s approach, except for CH4 and N2O, CO2 emission factors which are
specific to Cameroon. Assessment results show that GHG emissions have increased by 50.50% during the period
1995-2008. Cameroon’s road transport sector emits into the atmosphere an average of 1421.4 kilotons of CO2
equivalent per year, 852.5 (59.98%) and 568.9 (40.02%) kilotons of CO2 equivalent per year for gasoline and
diesel vehicles respectively. CO2 emissions in the road transport sector represent 34.33% of the total CO2
emissions in Cameroon due to the energy sector. The results suggest future policy implementation to support
sustainable alternative fuel and equally the deployment of low-carbon technology for vehicles, rejuvenation of
Cameroon's vehicle fleet, improve road traffic and encourage public transport.
