Abstract


Tanzania is among developing countries striving to combat the global warming through encouraging the initiatives on switching to natural gas from fuel oil operations. The study was conducted to assess the dynamic changes on greenhouse gases (GHGs) emission shares to provide data to inform effective climate change mitigation strategies from oil and natural gas operations. The most three influential and long-lived greenhouse gases - carbon dioxide (CO2), methane (CH4), and nitrous oxide (N2O) were studied. The assessment was done to all imported oil types and natural gas generated from Songosongo gas project. The developed global warming potential revealed that CO2 emissions contained the largest share of 96% followed by N2O (4%) and CH4 (about 0%). Although there was a decrease in the amount of imported fuel oils and natural gas in 2008, the N2O emissions increased significantly from the base year 2007. However, the national GWP developed from year 1999 had the largest share of CO2 (61%), followed by CH4 (38%) and N2O (1%). Therefore, the study revealed the dynamic changes on Global Warming Potential (GWP) toward increasing shares of CO2 and N2O, especially if the modern natural gas economy will overlay the current agricultural economy.
