General Introduction GHGs, Determinants, and Global Trends Transport Sector Oman Trends Implications Conclusion

Some Facts on GHGs • Global Greenhouse Gas Emissions. Worldwide, emissions of greenhouse gases from human activities increased by 26 percent from 1990 to 2005. Emissions of carbon dioxide, which account for nearly three-fourths of the total, increased by 31 percent over this period. Like in the United States, the majority of the world’s emissions are associated with energy use. • Atmospheric Concentrations of Greenhouse Gases. Concentrations of carbon dioxide and other greenhouse gases in the atmosphere have risen substantially since the beginning of the industrial era. Almost all of this increase is attributable to human activities. Historical measurements show that the current levels of many greenhouse gases are higher than any seen in thousands of years, even after accounting for natural fluctuations US EPA, 2010

Conclusions 

Conclusions/cont.

Demand for transport services in Oman is expected to increase due to the general increase in the following:      

population Industrialization economic growth income trend toward urbanization Globalization, and associated increase in world trade



Thus, GHG emissions, and the associated transport transport--related pollution will be exacerbated.



Growth in transporttransport-related GHGs is expected to be comparatively less than in previous years due to a number of reasons:   





If the same rate of growth in carbon dioxide emission is applied, the total estimated emission in year 2020 will be 23 23..5 million metric tons – up from 10..2 million in year 2007. 10 2007. TransportTransport-related carbon dioxide emission will reach 4.7 million metric tons, up from 2.04 million metric tons in year 2007. 2007.

newer and more efficient technologies in transport vehicles, stricter regulations on types and vintage of cars on roads, and fuels that are less polluting on combustion.

Conclusions/cont. • Reducing emissions is an enormous, and complex challenge; It is multidisciplinary and requires the cooperation and contribution of every component in a civil society. • Regulation, technology, awareness, moral and ethical responsibility and wisdom among citizens will play a central role to achieve this noble and inter-generational objective.
