Abstract
The Greenhouse Gas (GHG) emissions due to transport operations have drastically increased in recent years. The sea transport in particular contributes 2.7 to 3 percent of CO2, a major component of GHG emissions globally. Numerous measures have been undertaken locally and internationally to alleviate the sea transport share of Greenhouse Gases. However, most of these measures will be fruitful if ship investors (e.g., ship owners and operators) would fully employ the GHG emission reduction strategies. Due to the scarcity of the statistical data in this respect, this study therefore presents a rough set synthetic assessment (RSSA) model to GHG emission abatement strategies in the Tanzanian shipping sector. The results of the assessment reveal that the Tanzanian shipping companies engaged in Cabotage trade are aware of the abatement strategies and moderately apply them.

Scientific findings suggest that the Earth’s average temperature is gradually increasing
The results reveal the awareness of the Tanzanian shipping investors on the local and international regulations aimed at combating the Greenhouse Gases (GHGs) emission and its disastrous effects
The shipping industry is currently pressurized to reduce a drastic increase in CO2 emissions which negatively influence the world climate
Summary
Scientific findings suggest that the Earth’s average temperature is gradually increasing. The Intergovernmental Panel on Climate Change (IPCC) has predicted a rise in global temperatures of between 1∘ and 2∘ Celsius by 2020 and between 2∘ and 5∘ Celsius by 2070 [1] This phenomenon is a result of increased global emissions of Greenhouse Gases (GHGs) such as carbon dioxide (CO2), methane (CH4), nitrous oxide (N2O), and chlorofluorocarbon (CFC). CO2 emissions are forecast to increase by 150–250 percent by 2050, due to increased freight volumes [4] With this consideration and the fact that the demand for shipping services is relatively high compared to other modes of transport mainly due to the economies of scale, the trend on CO2 emissions from the shipping industry is expected to increase at an increasing rate. Effective strategies are necessary in order to combat this problem
