What are GHG?

A greenhouse gas (GHG) is a gas in anatmosphere that absorbs and emitsradiation within the thermal infraredrange.

Carbon dioxide (CO2)

Hydrofluorocarbons (HFCs)

Perfluorocarbons (PFCs)

Common Greenhouse Gases

Objectives

Obtain an Estimation of GHG emissions inKandy Municipality.

Compare GHG emissions of KandyMunicipality with other known cities in theworld

Suggest required reduction measures tobe taken in order to bring down GHGemission levels.

Collect data on GHG emissions related

with

1. Consumption of energy in the city-MainlyElectricity & gaseous fossil fuel.

emissions CO2eq(Gg) electricity

=

electricity demand in kandy(kWh) * emissionfactor(Gg/kWh)

2. Amount of Solid waste disposal as

landfills.

3. Emissions occurred in water treatmentplants.

emissions CO2eq(Gg) wastewaters

=

Amount of treated wastewater in kandy (Gg CBO5 ) *emission factor(Gg/Gg CBO5)

4. Agricultural Lands.

emissions CO2eq(Gg) Agricultural lands

=

Area of agricultural lands in kandy (Sq.km ) *

emission factor(Gg/Sq.km)

Calculation of the factors

When calculating factors a preciseapproach should be used.

So previous work carried out by

professionals will be used1. Bjrn Kstermanna, Maximilian Kainza

and Kurt-Jrgen Hlsbergena,(2008).Modeling carbon cycles and estimation

of greenhouse gas emissions fromorganic and conventional farmingsystems

Analysis & Results

Total GHG emissions in the city isevaluated giving details on contributionof each sector(Electricity etc.)

Results are presented as how many tonsof Equivalent of CO2 molecules isemitted .

Also percentage contribution of eachcontributor is Calculated.

Reduction measuresFinally suitable methods of Reduction of

GHG emissions can be developed

such as

1. Use of Renewable energy sources.

2. Using advanced methods to disposeof waste in order to minimize GHGemissions.

3. Use of solid waste to synthesisproducer gas using methods likeGasification

4. How cultivate farms with reducedGHG emissions as such
