How
green
is
online
shopping
Imagine
this
:
Sara
comes
home
from
a
long
day
at
work
,
using
her
Friday
evening
to
the
fullest
.
She
is
a
little
frustrated
because
she
needs
a
new
cell
phone
cover
as
soon
as
possible
;
she
dropped
her
phone
as
she
entered
her
flat
and
cracked
the
case
.
She
sits
in
front
of
her
computer
and
quickly
searches
online
,
finding
the
perfect
new
phone
case
.
She
orders
it
choosing
priority
shipping
.
Now
that
that
final
of
the
week
is
taken
care
of
,
she
goes
to
meet
friends
for
dinner
and
then
go
to
the
new
Star
Wars
film
at
the
cinema
.
She
drives
her
car
as
always
.
On
Monday
,
a
delivery
truck
arrives
at
her
door
and
drops
off
the
small
package
.
Her
new
phone
case
has
arrived
!
Researchers
are
concerned
with
the
-
of
such
situations
.
At
first
glance
,
one
might
think
that
online
shopping
keeps
consumers
home
and
in
effect
,
off
the
roads
.
But
when
the
of
delivery
trucks
required
to
sustain
this
new
method
of
shopping
are
considered
,
the
statistical
outcome
is
possibly
quite
different
.
Recent
studies
using
simulation
software
and
data
from
transportation
authorities
exploring
the
effects
of
delivery
trucks
on
transportation
networks
have
shown
surprising
findings
.
Home
shopping
has
grown
more
slowly
than
anticipated
,
but
traffic
has
gotten
worse
.
Researchers
have
also
warned
authorities
of
a
effect'
,
which
occurs
when
gains
in
efficiency
merely
stimulate
new
consumption
.
The
study
,
which
was
conducted
at
the
Delaware
Center
for
Transportation
,
stated
,
"
We
found
that
the
total
number
of
miles
travelled
hasn't
decreased
at
all
with
the
growth
of
online
shopping
.
"
Let's
our
initial
scenario
to
explore
how
this
could
be
:
Sara
drops
her
phone
as
she
arrives
home
.
She
knows
she
is
heading
out
to
meet
friends
and
then
go
to
the
movies
,
so
she
quickly
changes
her
clothes
and
heads
out
20
minutes
early
.
She
stops
at
the
mall
and
picks
up
a
new
phone
case
,
then
continues
on
with
her
evening
as
planned
.
She
has
driven
her
car
an
extra
five
minutes
to
reach
the
mall
.
No
delivery
truck
needs
to
be
dispatched
to
make
a
trip
to
her
flat
on
Monday
.
Granted
a
delivery
truck
may
combine
several
stops
into
one
trip
,
however
,
consider
as
well
the
parking
implications
.
Sara
parks
at
the
mall
in
a
proper
parking
spot
,
not
blocking
traffic
in
any
way
.
But
her
flat
is
on
a
busy
downtown
street
.
The
truck
is
trying
to
make
its
deliveries
on
a
time
crunch
.
The
driver
doesn't
have
the
patience
or
the
circumstance
to
search
for
appropriate
parking
?
they
double
park
blocking
traffic
for
maybe
five
minutes
as
they
run
the
package
into
the
building
and
search
for
the
correct
apartment
,
making
sure
their
delivery
reaches
Sara's
hands
.
Travel
time
for
the
people
blocked
behind
the
vehicle
increases
.
Traffic
delays
increase
.
Therefore
,
vehicle
emissions
increase
as
well
.
Another
suggestion
of
the
study
was
that
when
people
save
time
shopping
online
,
they
simply
use
that
time
for
other
social
activities
,
hence
still
using
personal
vehicles
to
the
same
degree
as
prior
to
changes
in
their
shopping
habits
.
Some
cities
are
implementing
new
regulations
to
counteract
the
complications
associated
with
the
increasing
number
of
deliveries
.
Many
cities
in
Europe
and
Asia
have
restricted
deliveries
during
rush
hours
.
London
is
looking
at
using
buses
for
parcel
deliveries
.
Even
food
delivery
companies
in
one
London
district
must
now
apply
for
authorization
to
operate
.
Apparently
,
as
with
most
changes
to
our
conventions
in
society
,
attention
still
needs
to
be
given
and
adjustments
made
for
online
shopping
to
be
considered
'green'
.
Let's
check
what
you
can
remember
