  • 00:00:00
    - Cities all over the world
  • 00:00:01
    are bursting with people.
  • 00:00:02
    More than half of us live in cities now,
  • 00:00:04
    and by 2050 that number jumps to nearly 70%.
  • 00:00:08
    That's a lot of people.
  • 00:00:09
    So how do we grow cities sustainably?
  • 00:00:11
    And with the climate crisis,
  • 00:00:13
    figuring out how we do that
  • 00:00:14
    is more important than ever before.
  • 00:00:16
    But there's one city that may be doing it better
  • 00:00:18
    than any other place on earth.
  • 00:00:20
    - We want to become the first
  • 00:00:22
    carbon-neutral capital city by 2025.
  • 00:00:26
    - So we packed up our gear
  • 00:00:27
    and headed here to Copenhagen, Denmark to find out how.
  • 00:00:30
    (upbeat music)
  • 00:00:36
    It's not surprising to learn
  • 00:00:37
    that two-thirds of the world's carbon emissions
  • 00:00:39
    come from cities.
  • 00:00:40
    That number is getting worse
  • 00:00:41
    as more of us move into cities,
  • 00:00:42
    which means a higher demand on infrastructure and resources.
  • 00:00:46
    So Copenhagen is on a mission to cancel out
  • 00:00:47
    all of their carbon emissions.
  • 00:00:50
    - My name is Frank Jenson,
  • 00:00:51
    and I'm the Lord Mayor of Copenhagen.
  • 00:00:52
    When I became mayor we started this process,
  • 00:00:55
    we decided that we want to become the first
  • 00:00:57
    carbon neutral capital city by 2025.
  • 00:01:01
    - What is carbon neutrality actually mean?
  • 00:01:03
    For a city, it's creating more renewable energy
  • 00:01:06
    than the dirty energy it uses.
  • 00:01:07
    It's all about achieving a net zero.
  • 00:01:09
    And their plan is focusing
  • 00:01:11
    on mobility, pollution, and energy.
  • 00:01:14
    - We have introduced a lot of new solutions
  • 00:01:16
    in Copenhagen.
  • 00:01:17
    Our bicycle infrastructure is world famous
  • 00:01:19
    because today 62% of the Copenhagener's use the bike
  • 00:01:22
    for daily transportation.
  • 00:01:24
    - Everyone in Copenhagen bikes.
  • 00:01:25
    And I mean everyone.
  • 00:01:27
    So the city is leaning into that.
  • 00:01:28
    In the last 10 years it has invested nearly $300 million
  • 00:01:31
    to improve biking infrastructure.
  • 00:01:33
    All that money has paid off.
  • 00:01:35
    There are more than five times the amount of bikes
  • 00:01:37
    than cars in the city.
  • 00:01:38
    That goes a long way when cutting down on carbon emissions.
  • 00:01:41
    But the effort doesn't stop there.
  • 00:01:42
    Copenhagen has totally transformed their waterways too.
  • 00:01:45
    Only a few decades ago, the harbor was contaminated
  • 00:01:47
    with industrial waste, oil spills, even dead fish.
  • 00:01:51
    - When I moved to Copenhagen back in 1987,
  • 00:01:53
    this harbor was so polluted,
  • 00:01:55
    you could never dream to have a swim in this harbor.
  • 00:01:58
    But today you can swim.
  • 00:01:59
    We have a harbor bath where people can have a swim
  • 00:02:02
    with their kids after school or after job.
  • 00:02:04
    - Though Copenhagen has made huge strides
  • 00:02:06
    with their mobility and pollution efforts,
  • 00:02:07
    by far their biggest focus is on energy use.
  • 00:02:11
    It makes up about 80% of their carbon neutral plan.
  • 00:02:14
    To cut down on their consumption,
  • 00:02:15
    Copenhagen uses one of the world's largest
  • 00:02:18
    and most successful district heating systems.
  • 00:02:20
    It works by using a network of pipes
  • 00:02:22
    to capture left over heat from electricity production,
  • 00:02:24
    then delivers that heat to homes across the city.
  • 00:02:27
    - 99% of all households in Copenhagen are linked
  • 00:02:30
    to our very efficient district heating system.
  • 00:02:33
    We have also introduced district cooling,
  • 00:02:35
    where we take the cold out of the water in the harbor
  • 00:02:38
    and distribute cold in pipes
  • 00:02:40
    beside the district heating pipes.
  • 00:02:42
    So you can reduce temperature in buildings,
  • 00:02:45
    in server rooms, in factories.
  • 00:02:46
    We can reduce electricity use for cooling down buildings
  • 00:02:49
    for 70%.
  • 00:02:50
    - To come up with these kinds of sustainable solutions,
  • 00:02:53
    Copenhagen collaborates with partners across the city.
  • 00:02:56
    Like Copenhagen Solutions Lab.
  • 00:02:57
    An incubator for smart city initiatives.
  • 00:02:59
    - What Copenhagen Solutions Lab does
  • 00:03:01
    is actually solving some of the bigger problems
  • 00:03:04
    in the world by using technologies
  • 00:03:05
    in order to accelerate this transition
  • 00:03:07
    into a carbon free economy.
  • 00:03:09
    So for instance, a problem of air quality,
  • 00:03:11
    people in cities are dying too early
  • 00:03:13
    because of bad air.
  • 00:03:14
    And that is a global problem,
  • 00:03:15
    not just here in Copenhagen.
  • 00:03:17
    Getting rid of our waste, measuring air quality,
  • 00:03:20
    managing traffic, we're trying to solve
  • 00:03:22
    these problems down in Street Lab.
  • 00:03:24
    - Contrary to how it sounds,
  • 00:03:26
    the Street Lab really isn't a laboratory.
  • 00:03:28
    It's a two kilometer long chunk of downtown Copenhagen
  • 00:03:31
    that serves as a testing area.
  • 00:03:32
    - Placing a lab such as this downtown,
  • 00:03:35
    in a real urban environment,
  • 00:03:36
    makes it very realistic.
  • 00:03:38
    Everything we're testing here
  • 00:03:39
    will be able to survive in other parts of the city
  • 00:03:42
    and will be able to be scaled to a city-wide level.
  • 00:03:45
    This is a new generation of technology
  • 00:03:47
    that makes it possible to measure air quality
  • 00:03:49
    by a sensor.
  • 00:03:51
    And now we're looking into mounting sensors
  • 00:03:53
    actually on a Google Street View car
  • 00:03:55
    to make it possible to measure each and every street
  • 00:03:58
    of Copenhagen.
  • 00:03:59
    - With these sensors, the city can better locate
  • 00:04:01
    the source of pollutants
  • 00:04:02
    to help improve overall air quality.
  • 00:04:04
    The technology has already proved so useful,
  • 00:04:06
    that Marius and his team are shipping sensors
  • 00:04:08
    to countries like Norway, Mexico, Austria, Greece,
  • 00:04:11
    and the US.
  • 00:04:12
    Though Copenhagen is leading the way
  • 00:04:14
    in sustainable smart city solutions,
  • 00:04:16
    experts and policy makers will tell you
  • 00:04:18
    that the true secret to the city's transformation
  • 00:04:20
    is the people.
  • 00:04:22
    The residents here actually want to help
  • 00:04:23
    build a sustainable city and are willing to work for it.
  • 00:04:26
    - The citizens of Copenhagen,
  • 00:04:27
    they demand a high quality of urban life.
  • 00:04:31
    They are willing to do a lot themselves.
  • 00:04:33
    They want to sort their own garbage,
  • 00:04:35
    they want to bike to work.
  • 00:04:36
    Citizens involvement is key to the way we think
  • 00:04:39
    in Denmark and in the Nordic countries.
  • 00:04:41
    And that's a huge driving force behind
  • 00:04:44
    being a carbon neutral city by 2025.
  • 00:04:48
    - Since I became mayor in 2010,
  • 00:04:51
    we have had a growth rate in the number
  • 00:04:52
    of citizens with 20%.
  • 00:04:54
    And even that, we have cut our emissions with 42%
  • 00:04:58
    in the same period.
  • 00:04:59
    So we show that you can have growth
  • 00:05:01
    with green transformation if you do the right investments
  • 00:05:04
    in the city.
  • 00:05:05
    - Copenhagen's transformation hasn't been easy.
  • 00:05:07
    And of course their size and wealth helps.
  • 00:05:10
    But they've made it work for their city.
  • 00:05:12
    Regardless if they hit their carbon neutral deadline,
  • 00:05:14
    their ultimate goal is to serve as an example
  • 00:05:16
    for cities everywhere.
  • 00:05:18
    - The green transformation of cities and livability
  • 00:05:21
    and also very important, good economy.
  • 00:05:24
    Goes hand in hand.
  • 00:05:25
    I see Copenhagen as a front runner
  • 00:05:27
    to show for my colleagues and decision-makers,
  • 00:05:31
    you must go green.
