Transcripts
communities
around the world are currently faced
with a number of large-scale
environmental challenges
including dangerous irreversible climate
change
many of these challenges stem from
cities
and are resource-intensive urban
lifestyles
fortunately an array of concrete
solutions to these challenges
are already being developed and
implemented in cities
around the globe so we set off on an
inspirational journey
to explore the most innovative ideas
technologies
and initiatives being used by cities
today as they strive to create
more livable and sustainable cities
and with the potential to stimulate
widescale change
which would set us on the path towards a
one planet future
where humans live in harmony with nature
the struggle for a sustainable future on
this planet will be
won or lost in our cities in the next 30
years
we expect a doubling of the global urban
population
and with that a doubling of the global
urban infrastructure
that is a very short window of
opportunity to get things right
so urban investment decisions taken
today
will determine whether people will be
locked into
resource inefficient and fossil fuel
dependent
infrastructures and lifestyles or if
they will enable cities to become places
where we can live
attractive and healthy and sustainable
lives
over the next 30 years more than five
times the global gdp
will be invested in urban infrastructure
and its use
so it's critical that those investments
are made in a sustainable and resilient
way
a number of actions that cities have to
take
and actually take together is first of
all to try to become
low carbon to shift from fossil fuel
towards renewable energy secondly to
become resilient
we are going to face the impacts of
climate change and they will be
different
from one part in the world to the other
part we have to look
thirdly into how can our existing
ecosystems
our biodiversity that we have in urban
areas how can that
support us in our sustainability
well the urban challenges the world is
is tremendous i mean we'll soon have 75
of the world population living in cities
and i would argue that the number one
challenge for cities is actually not
inside the city
it's to recognize that it has to be
sustainable in its entire
inflows and outflows of energy of
water of food of all materials so to see
itself like they're part of a wider
ecosystem so that you plan
every urban area for every citizen that
it keeps itself within a circular
economic model
in terms of resources in and out and the
second most important is to
build resilient cities so how are
leading green cities around the world
responding to this enormous challenge
one of the most ambitious climate action
plans has been adopted
by the city of vancouver whose goal is
to run the city on
100 renewable energy by 2050
vancouver's plan focuses on vibrant and
inclusive neighborhoods
and creating a city that meets the needs
of generations to come
they intend to achieve this by working
with a broad range of stakeholders
throughout society
when i first campaigned for mayor in
2008
one of my key priorities was to make
vancouver the world's greenest city by
2020.
so we put together an action plan worked
with
citizens and businesses and
neighborhoods
put together 10 targets in water
food clean air green business green jobs
reducing our carbon reducing our
consumption and
zero waste
at the beginning we were worried this
was too much for people like that they
wouldn't
be able to see a point of entry into it
and we were totally wrong
and we've had over 35 000 residents 180
organizations who engaged in writing our
plan
tens of thousands of residents who've
been involved in implementing because
when they write the plan
they own the plan
and as a result we've had over 150
separate city policy initiatives
that range from big farms in the middle
of a dense city like vancouver
waste recovery that we've had we've had
technology that we're doing i'm green
economy we've raised our green jobs by
19
we've reduced our water usage by 18 uh
greenhouse gas emissions are way down
because
many more people are biking and walking
and taking transit
but it's really the innovation is how
you marry
a government to the residents to the
businesses
to the different civil society groups
and make it a collective effort
creating a fossil fuel-free city is
possible but requires
a shift to green energy in all areas
our new goal is to be 100 renewable in
the city of vancouver with all of our
energy sources
and it will be a challenge with
transportation in particular we don't
know
when we will have electric vehicles for
the whole city
we're waiting on the industry side to
get a clear sense of
what year that's possible we're planning
out the timeline right now
basically making decisions to eliminate
fossil fuels from
our city many experts today refer to
renewable energy technologies
as disruptive in the sense that they're
radically different
from conventional technologies and are
so much better for
consumers and society that they will
very quickly disrupt current paradigms
once the technology is ripe they happen
very quickly and i think
electric cars and solar energy and wind
energy they're right
a lot of people think they have these
forecasts for you know
20 40 we're having just a bit more
percentage of these
i think the transformation is going to
happen so quickly that most of these
forecasts are going to be
quite short you know quite often because
these are disruptive technologies
they're better technologies for the
consumers
and we've crossed the price points where
they make sense
so once that happens it's basically a
matter of awareness
getting around word of mouth the
understanding the experience
and as that grows it grows exponentially
and we're going to see a rapid i think a
transformation
you know comparable to the industrial
revolution or such
so this is a solar energy installation
here in vancouver british columbia in
fact when we first started 10 years ago
people told us we couldn't do this that
it didn't make sense here
but we recognized that there were some
people that wanted to install solar that
wanted to do something leading edge that
wanted to do something to reduce their
environmental footprint
so we started with these panels uh this
system
uh since then uh the installation growth
has been about 40
per year uh so in fact it could be done
here there was a demand people want to
see more renewable energy installed
locally
the research that we're doing is looking
at the transportation sector because
that's a
huge part of our greenhouse gas
emissions and about how we can connect
our transportation system to renewables
and we're finding that
really electric mobility is an essential
part of meeting our deep
greenhouse gas emissions reduction so to
have at 80 reduction by 2050
we need to have a big fleet of electric
vehicles uh really almost in every city
around the world and the research we're
doing finds that there's a lot of
potential demand there's a lot of
consumers out there who'll be willing to
pay extra for some type of plug-in
hybrid vehicle
or pure electric vehicle but currently
they they can't do that because it's not
available in the model they want or in
the variety
or color or whatever it is that they
want and so we're finding is there's
some
areas that are showing us a good
examples of policy
that can trigger that change and
california has the best example
that we found
california right now is leading
the standards they've said that ten
percent of the vehicles sold in
california
have to be electric vehicles they have
committed
to an 80 reduction in greenhouse gases
if other states washington oregon
british columbia ontario quebec and nine
eastern states
were to adopt that kind of california
policy
we would create a demand for electric
vehicles that would make them very
commonplace
and we would get to the point where
using
the weight of states and the weight
of cities we could begin to transform
our our emissions and that's where we
need to go because we cannot wait for
national governments to take us there
anymore
and once people understand
that an electric vehicle is actually
cheaper
it saves them money all of a sudden
that will turn the market in in a
massive way
like transportation housing is also a
major challenge
in the aim of creating sustainable
cities the vancouver convention center
is a prime example of how buildings can
be designed to minimize environmental
impacts
we're here at the vancouver convention
center's west building which opened in
april 2009
and it's actually one of the greatest
convention facilities in the world
and just to give you a few examples we
have
really visible sustainable features such
as our six-acre living roof which is
the largest in canada we have a very
sophisticated
black water recycling treatment plant
in-house as well as
we utilize sea water heating and cooling
because we're right on the harbor
here at the vancouver convention
center's living roof this is six
acres and it's actually one of the ten
largest green roofs in the world
so what makes this green roof really
unique is the fact that we've chosen
plants that are all
indigenous to british columbia so we've
actually planted over four hundred
thousand
plants and grasses on top of this area
it really connects to other green spaces
here in downtown vancouver
so if you're looking at downtown
vancouver from an aerial perspective
you're gonna see that this space
connects to the park next door
and it connects to stanley park and it
really was part of the vision of our
architects
so the mega city and capital of south
korea
has seen a remarkable positive change
thanks to courageous green initiatives
the city has been recognized for its
determination
to ramp up the use of renewable energy
and building citizen engagement
may be many diverse options and policies
to combat the climate change issues
the city like so has
more than 10 million citizens so we
should provide more
environmental transportations and also
bring solutions to the buildings
which is more environmental but most
important thing is
to mobilize the citizens engagement
and participation in this process
during our development period there are
too many
roads and too many cars and citizens
accustomed to using cars so instead of
it we should
build the more eco-friendly
public transportation such as subway
or bikes so i
really encourage the citizens to have
their own
ideas and actions
an impressive initiative by the city of
seoul is its goal to achieve
20 electricity self-reliance by 2020
obviously renewable energy plays an
important role
in this transition
so the solar panels here are installed
on top of
a filtering reservoir of the water
purification
plant that filtering reservoir
has a cooling effect so the solar panel
become more efficient
so the average uh power generation hours
and so
it's a 3.1 or 3.2 hours per day
but here thanks to that cooling effect
the figure is higher than the average
which is 3.7 or
8 hours per day so metropolitan
government has this campaign of
one less nuclear power plant and this
uh pivo plant contribute to the campaign
so we hope that this type of plant
are distributed and expanded around the
soul city
along with renewable energy production
lowering a city's overall energy
consumption
by constructing buildings and houses
that consume very little or no energy
is key one approach is to use passive
design in any green building the first
thing we have to do
is work on passive design maximizing the
energy
that we can get from passive design
passive design means
we use a lot of insulation we use
special glass
and special curtain walls to make the
envelope
optimal so that the energy does not leak
through the walls let nature work with
you
instead of trying to work against nature
let nature
cool us and heed us passive design
techniques allow us to do that
to tap the nature to provide us with our
needs
one of the great features of this
building
are these incredible green walls it
brings nature
into our urban environment and some
scientists say that when we see
green it just helps us feel good and
relieve our stress on the whole rooftop
there's solar panels so this
building is generating a lot of
renewable energy
to provide electricity to this building
gothenburg in sweden has been recognized
for its innovative climate strategies
the introduction of green bonds and for
its work
to decrease residence consumption-based
carbon emissions
another key to success is cooperation
with academia
and the financial sector
i think the reason for the success story
about gothenburg and
the environmental work and especially
climate work is that we have
been good at cooperation and one example
for us is like when we
together with a.b volvo and others
built a new completely new electric bus
a bus which didn't exist but we decided
we want
that bus and the city planned in in
their way
volvo planned of course with creating
the bus and the bus was there after
less than two years and now you can see
the light green bus going up and down
the streets of gerbenberg gothenburg is
a leading city when it comes to looking
at the larger picture
for example taking its residents
consumption-based carbon footprint into
account
when considering how they impact the
environment
the consumption-based carbon footprint
means that
when we calculate emissions in the city
from the citizens
we not only look at the missions that
are are emitted
within the city's borders we also take
into account our consumption
of products and services that causes
emissions
in other countries and other parts of
sweden by doing so
we also get new perspectives on which uh
climate issues that we have to focus on
normally when we have a
geographical perspective that is the
traditional way in cities and
countries there's a lot of focus on
transport energy production and industry
and that's important
but with the consumption-based carbon
footprints we're also going to focus
on the consumption of food the
consumption on
air travel and other kind of consumption
in 2008 green bonds was launched by the
world bank
as a tool to guarantee that money is
invested
in sustainable projects gothenburg was
the first city in the world
to issue such bonds
i think the cornerstone for green bonds
is the simplicity
the essence of the green bond is that is
earmark money in that way when we issue
a bond you offer the investors the
opportunity to invest in specific
projects so they know exactly where
their money
money is going so far we have invested
in electric cars
biogas production and also in a water
purification filter
when you take those two extremely strong
forces finance and sustainability
and make them move forward together you
create something really exciting
actually
sometimes there's a political will for
sustainable change but the city
lacks the financial resources to see it
through one such example of how to help
bridge the gap between private and
public sectors
is the swedish company sustainable
lifestyle scandinavia
the world is facing a huge challenge in
coming decades with close to three
billion
people moving into urban districts which
means that we
we have to take on a sustainable
approach in order to build
the urban environments and there we saw
that
the political will is there but there is
a lack of
know-how knowledge and capital and
that's where we
in sustainability livestock scandinavia
bridge that gap
the concept has already been proven
successful and is now being implemented
in the chongyang county in china
where private capital is fueling the
sustainable expansion of the city
that
the first step is making it a
demonstration project to secure
governmental support next step is making
the
master planning and infrastructure
design and then comes
attracting the finance to capital and
then final step is
implementation
the city of paris host to the united
nations conference on climate change
has been recognized for its huge
commitment to create a more sustainable
city by focusing on sustainable mobility
renewable energy and the reintroduction
of nature in the city
paris resoluments
energy
we have now in paris a big issue about
hair pollution this is big trouble for
health as well
so we have decided to develop many
measure on one hand we
give incentive to people that they shift
to a
sustainable mobility and on the other
hand we have a special program that
state by step is going to forbid the
most polluted cars within the city by
2020
that just like the cleanest one can
circulate it
in the city to a lower lower that
pollution
we are subsidizing for taxis and
individuals the purchase of
clean electric vehicles also the buying
of electric bicycles if
you buy an electric bicycle you get a
subsidy
out of the fourth of the total price
from the city of paris so
we are really pushing very hard on
electric vehicles it's one of our
priorities and now we can see the reason
that
persons are promoting the electric
vehicles
increasing investments in renewable
energy and retrofit programs
is a clear priority for paris as is
their sustainable
development action network in paris
we're going to have many action in the
next years to implement our climate
action plan
but i would say we have three big issues
right now it's to develop
green energies in the city it's also to
strengthen our
retrofit plan to uh mitigate gag
emissions but also to tackle energy
poverty
we have in paris created what we call
the sustainable development action
networks and it gathers
individuals association but also
startups that having
make commitments to face climate issues
and instead of being alone in that in
that
fight we are gathering them helping them
to share experiences
to go to grow bigger and also to be more
known from the paris population and this
network now is gathering nearly 10
percent of the paris population
two south african cities cape town and
schwanne
have both been praised for their
commitments to sustainable development
while simultaneously battling challenges
such as poverty and social inequality
in the city of china and in south africa
in general we've got we are faced with
triple challenges that
of unemployment poverty and
inequality so it's important that you
are able to skill people to participate
in the mainstream economy
we all have a responsibility as citizens
to do what we can to protect
the planet from the harmful effects of
climate change
and it is an imperative that we see a
shift
from our reliance on traditional energy
sources
and look to as many cleaner energy
sources
as possible one of our natural
advantages
is the number of sundays so we must
exploit that resource and that's why
we're introducing
solar powered energy but we also want to
use it to resolve the
housing question in our city so as we
expand and give more free houses to the
poor
we the roof panels must be designed in a
manner that we are able to put the solar
panels
so in this way you are resolving both an
existing and immediate
question but also a future question with
regards to your energy mix
and that's how we want to use solar
going forward
it's clear that cities need the support
of national politicians
and strong policies in order to achieve
their real potential
and ambitious goals a combination of
both
a top-down and bottom-up approach is
absolutely necessary
and demands a common effort that truly
involves
city residents
changing our energy system to renewable
energies is possible technically
possible
but we have to move very fast the
economic
framework the legislative framework we
have to inform
people we have to make actions on all
level
i myself on my roof and everyone else in
his city in this municipality
and in this region and if we do that
then we can reach a 100 renewable world
in 2015. leaders in a city
do have to approach individuals to make
them
partners it cannot be done top down
people have to embrace solutions and
feel that they are part of of a new
world
