Abstract:
The global warming caused by the Green House Gas (GHG) is a hot topic in recent
year in the world. Transportation activities generate GHG and contribute to the global
warming. This assessment was conducted to calculate the total GHG accumulation
from transport related operations at Brandix Lingerie (Pvt) Ltd, Wathupitiwala for the
year of 2015. The employee transport network was mapped using Google earth
program to estimate passenger kilometers between each get – in and get-down
locations. Upstream and downstream goods transportation was mapped to estimate
ton – kilometers of goods transportation using existing transport management data.
Transport related GHG emission was calculated using internationally recognized fuel
based emission factors and tone kilometer based emission factors where applicable.
The findings indicate that the amount of organizational GHG emission of
transportation was 609.04 tons CO2e per year. Worker transportation has contributed
47.26% to total GHG emission and it was 287.85 tons CO2e. Business purposes
transportation covered 14.96% and it was about 91.12 tons of GHG emission. The
upstream transportation (external vehicles that come to stores) contributes 178.37 tons
of CO2e emissions and it was estimated as 29.29% from total GHG emission in 2015.
The downstream transportation (shipments) contributes the 51.7 tons CO2e and it is
estimated as 8.49% from total. Per product GHG emission from worker transportation
was 0.0129 KgCO2e, business purposes transportation was 0.0041 kgCO2e. The
upstream transportation Key Performance Index (KPI) was estimated as 0.0080
KgCO2e and per product GHG emission of downstream transportation was estimated
as 0.0023 KgCO2e for the year 2015.Estimated GHG saving potential with improved
Transport Demand Management system (TDM) is 89.71 tons CO2e.
