To what extent are CO2 emissions from intra-urban shopping trips by cars affected by drivers’ travel behaviour and store location?
Abstract: Transportation is seen as one of the major sources of CO2
pollutants nowadays. The impact of increased transport in retailing should
not be underestimated. Most previous studies have focused on transportation
and underlying trips, in general, while very few studies have addressed the
specific affects that, for instance, intra-city shopping trips generate.
Furthermore, most of the existing methods used to estimate emission are
based on macro-data designed to generate national or regional inventory
projections. There is a lack of studies using micro-data based methods that
are able to distinguish between driver behaviour and the locational effects
induced by shopping trips, which is an important precondition for energy
efficient urban planning. The aim of this study is to implement a
micro-data method to estimate and compare CO2 emission induced by
intra-urban car travelling to a retail destination of durable goods (DG),
and non-durable goods (NDG). We estimate the emissions from aspects of
travel behaviour and store location. The study is conducted by means of a
case study in the city of Borlänge, where GPS tracking data on intra-urban
car travel is collected from 250 households. We find that a behavioural
change during a trip towards a CO2 optimal travelling by car has the
potential to decrease emission to 36% (DG), and to 25% (NDG) of the
emissions induced by car-travelling shopping trips today. There is also a
potential of reducing CO2 emissions induced by intra-urban shopping trips
due to poor location by 54%, and if the consumer selected the closest of 8
existing stores, the CO2 emissions would be reduced by 37% of the current
emission induced by NDG shopping trips.
