E-International Scientific Research JournalISSN: 2094-1749 Volume: 2 Issue: 4, 2010the Philippines in mores advanced countries, for instance, vehicles that are more than five (5)years old are automatically phased out (Japan, Land Transport Ministry, 2005).Importation policies for vehicle surpluses should similarly be reviewed in particular,tax penalties for buying surplus vehicles can be set higher in order to discourage localconsumers from patronizing the products.ConclusionThe City of Dipolog contributes a significant portion to the country’s annual COemission, and inordinately so (>6%). Such a huge annual CO emission can be attributed to themain factors that obtain in the city: (a.) presence of fuel inefficient motorized tricycles whichconstitute the bulk of public transport in the city, and (b.) huge number of older vehicle typeswhich are also inefficient in burning fuel. Serious under reporting of the CO emissions of oldervehicle types lead to the conclusion that the implementation of RA 8749 or the Clean Air Actleaves much to be desired in the city.References;D.

E-International Scientific Research JournalISSN: 2094-1749 Volume: 2 Issue: 4, 2010ESTIMATION OF GREENHOUSE GAS (GHG)EMISSION LEVEL FROM WASTE AND GARBAGEDISPOSED IN THE COASTAL BARANGAYS OFDAPITAN CITY: IMPLICATIONS TO THEIR WASTEMANAGEMENT PRACTICESAbstractS. Campiseño and R. LaranjoJose Rizal Memorial State University – Main Campus, Dapitan CityJose Rizal Memorial State University – Main Campus, Dapitan CityWastes and garbage disposed of by the coastal barangays of Dapitan City wereanalyzed as to volume, composition and manner of disposal in order to estimate theapproximate level of daily greenhouse gas (GHG) emissions using an international conversionfactor by the International Panel on Climate Change (IPCC) conversion manual. The wastemanagement practices of the barangays were likewise determined since these determine to alarge extent the volume of GHG emitted through household wastes. Results revealed thatroughly 43.8 kilo-tons of CO2, 2.52 kilo-tons of methane and .515 kilo-tons of nitreous oxideper year are derived from the household wastes alone owing to their poor waste managementpractices. If open burning and other improper waste disposal practices were strictly prohibitedand violators apprehended, the greenhouse gas emissions can be reduced by as much as 50%of their current levels.Keywords: biomass conversion factor, greenhouse gas, waste managementIntroductionMuch of the accumulation of greenhouse gases in the atmosphere can be attributed tothe activities of man: from the mundane household wastes to the wastes generated by largeindustrial plants. The manner in which these wastes are disposed of also determine the amountof harmful gases, notably carbon dioxide and methane, that these wastes give off. Opendumping and burning are two(2) of the more seriously damaging manner of waste disposal thatgreatly contribute to rise in global temperature (IPCC, 2009).The lack of environmentally friendly, sustainable and affordable waste managementhas led to open dumping and open burning of solid wastes in many parts of the world. Opendumping encourages scavenging for recyclable materials that pose real health hazards to thecommunity. On the other hand, open burning results in particulate matters or black carbon inthe higher altitudes of the earth , where ice is common, resulting in greater absorption of thesun’s energy thus trapping heat in the earth’s atmosphere. Global warming results from theexcess heat trapped in these areas causing ice to melt and consequently, producing variouskinds of aberrant weather patterns.309
