What
is sustainability?
Sustainable development is a concept that is often invoked but difficult
to define. The Bruntland Commission memorably defined it in its 1987
report "Our Common Future" as "development that meets the needs of
the present without compromising the ability of future generations
to meet their own needs."
How do
you know our population will grow by almost one million more people?
The Population
Division of the Department of City Planning has done a detailed
projection of the City's population. This analysis, done on the
level of each borough, has taken into account the current age and
sex breakdown of the population; birthrates by borough; immigration
patterns (not based on origin); life-spans; and patterns of people
moving out of the City. With this information, we strongly believe
that the City's population will grow, primarily due to three factors:
continued immigration; New Yorkers are choosing to stay in their city
longer, rather than moving out to the suburbs or to another city;
and finally, we are living longer. For these reasons, our population
of school-age children will not increase dramatically, but we will
have many more seniors.
What
is global warming? What are its effects? How does it directly affect
NYC?
Global warming is the effect of increased carbon dioxide and certain
other gases in the atmosphere. These gases have a "greenhouse
effect" by which sunlight gets converted into heat and then trapped
inside the earth's atmosphere, which raises its temperature - just
as the glass in a greenhouse does. This impact has increased average
temperatures worldwide; melted glaciers in both the Arctic and the
Antarctic; and intensified hurricanes and other storms. Locally -
as we have found in our work on PLANYC - it has already raised the
sea level at Battery Park and increased summer temperatures, as measured
right here in Central Park.
What
is carbon? What are greenhouse gases?
Carbon dioxide is a by-product of burning energy. Certain types of
fuel produce more and some produce relatively less - coal, for example,
emits lots of carbon, but natural gas produces less. Methane is also
a serious greenhouse gas, which is produced in landfills as they decompose
and from sewage.
Which
other places have set a carbon target? What is it?
Lots of places have set carbon targets; including Chicago, California,
most European countries, and all of the 163 countries that signed
onto the Kyoto accords. A carbon target means identifying how much
carbon you create currently and working to reduce those emissions
by a certain percentage.
What
are the main sources of greenhouse gases?
We are still working on our inventory of all carbon created by New
York City and its vibrant economy. But, in general, there are three
main sources: fuel burned to make electricity, fuel burned for heat,
and fuel burned in trucks, automobiles, and airplanes.
What
is an urban heat island?
Scientists often mention the "urban heat island effect."
They are referring to the fact that cities are often hotter than the
surrounding areas because the asphalt in our streets and the concrete
in our buildings retain heat. In contrast, areas like the suburbs
that have more trees, more grass, and relatively less concrete tend
to be cooler. For PLANYC, we have measured this effect here in New
York and the City is generally five degrees Fahrenheit hotter on a
summer day than the surrounding suburbs.
What
has the City already done?
New York is already a world leader in the fight against global warming.
First of all, we're the most energy-efficient city in America; the
average New Yorker consumes less than half of the electricity of someone
who lives in San Francisco and nearly one-quarter the electricity
consumed by someone who lives in Dallas. Second, we've got the best
transit system - and the highest usage. This is all the result of
our density - because urban living is the most environmentally friendly
way to live.
More recently, we've also been a leader in green technology and green
practices. We've replaced virtually every red and green stoplight
in the City with highly energy-efficient, cutting-edge LED lights.
The City government owns the largest fleet of hybrid fuel vehicles
in North America. With our new green building law and our environmentally
preferable purchasing law - products of our close collaboration with
the City Council - we're now pushing even further ahead.
What do we need
to do about water quality?
DEP is currently working with the State to develop a long-term control
plan to improve our waterway quality. In addition, we need to explore
innovative best practices that will prevent stormwater that isn't
polluted from entering the sewage system.
What
is a CSO? Why is it a problem?
A "CSO" is a "combined sewage overflow." What
that means is that most of New York City - like most older cities
in the country - have a single, combined sewer system that handles
sanitary waste as well as storm water. When it's not raining, sewage
treatment plants can handle all of the sewage we produce and clean
it up. But when it rains, the vast amount of rainwater that goes into
the sewers exceeds their capacity, so some of it must be released
into the rivers untreated. That's why sometimes, after heavy rain,
we have to close beaches.
Are you
working with the MTA? The Port Authority?
We have spoken with the MTA and the Port Authority as we have developed
these challenges. Our projections are in many cases based on their
own work. We look forward to working closely with them, and with other
agencies in the region, to develop solutions to the challenges ahead.
Isn't it
the MTA's fault that the subway is so crowded?
In many cases, no. They've announced that they'll expand service on
the L train, which is crucial, and on the G train, which currently
has infrequent service. But the Lexington Avenue line there's simply
no more room to put more trains, longer trains or more riders. The
only way to solve that problem is to build the Second Avenue line,
which depends on figuring out how to finance it fully. Only the first
phase - on the Upper East Side - currently has any financing at all.
Will you have a
new initiative for affordable housing? Will you be upzoning neighborhoods?
We are looking for ideas for solutions; we have not decided anything.
The Bloomberg Administration's affordable housing plan provides a
solid start to get us to 2013. But over the long term, if we don't
address the overall supply of housing, we'll never really address
the housing shortage. That means we'll continue to work with communities
to develop thoughtful, neighborhood-focused plans to accommodate the
city's growing population. This would include upzonings where appropriate,
while ensuring that neighborhood character and quality of life concerns
are addressed.
What
is a state of good repair? What does it include? Does it include upgrading
all stations to be handicapped accessible?
A "state of good repair" is a somewhat technical term. It
means, generally, that there's no deferred maintenance: no leaks left
unrepaired; that painting is done on a regular basis; that there aren't
any obsolete parts of the system that can't be replaced easily. It
doesn't include handicapped accessibility at all stations, but it
does include achieving accessibility at the 100 most important ones.
Anything beyond that is not included in the definition of "state
of good repair" - but there are clearly more improvements that
should be made.
Will you be
building more power plants?
Not necessarily. There are lots of options for how we ensure that
we have a clean and reliable source of energy. We could find ways
to reduce our overall electricity consumption - whether by using more
efficient compact fluorescent lightbulbs or installing more efficient
air conditioners. We could repower existing plants with more efficient,
higher-output, and less-polluting generators. We could draw in more
electricity from outside the city by building new transmission lines.
And new technology - already in service - means that many buildings
can cost-effectively install small, efficient, and environmentally-safe
generators to provide their own power on-site.
How many
brownfields are there?
There is no definitive list of brownfields because the definition
of "brownfield" is subjective. The definition includes sites with
known contamination and sites that are suspected of being contaminated.
We do know that at least 1,700 acres of land in the City are enrolled
in various state programs to address contamination at least on parts
of the site. We also know that many other sites are contaminated to
varying degrees, and that there are other sites out there - former
dry cleaners, former factories where chemicals were used, sites created
with fill material, etc. - that may also be contaminated.
Where are they
located?
There are brownfields in all five boroughs. Many are located near
waterways and in current or former industrial areas.
Can
schools and other facilities be built on brownfields?
If a site is cleaned to a high enough standard, it can be used for
virtually any use, including schools. A site's planned use generally
drives the level of clean-up done and how exposures are prevented.
Don't we
need to have a plan to ensure that the jobs exist?
Our projections of roughly three-quarters of a million new jobs in
the five boroughs by 2030 are based on existing and long-term trends.
New York has a diverse economy and continues to attract businesses
drawn by its tremendous labor pool, its business services and networking,
and its global prestige. We must continue the kind of support that
the Economic Development Corporation and the Department of Small Business
Services provide to assist businesses in various sectors. Our main
challenge will be to provide the space for businesses to locate -
as we have done in areas from the far West Side to the Industrial
Business Zones. We must also ensure that the City's quality of life
remains as good as it is today - or better.
How do you know
that millions more visitors will come to New York?
In the 15 years since 1991, we nearly doubled our annual visitors
from 23 million to 44 million. We expect to reach 50 million visitors
by 2015, or sooner; even at modest growth rates thereafter, it is
likely we would get above 60 or 62 million by 2030. After that, we
begin to run into challenges caused by capacity constraints at our
airports and limits on the number of hotel rooms that we can reasonably
expect to be developed in the City.
Why have you not
considered...schools...health...poverty?
We view this effort as building on, not replacing, the other major
projects that the City has undertaken already. Obviously, New York
has many long-term needs: continuing to keep crime down and preventing
terrorism; continuing our work to improve the schools and expanding
capacity; addressing poverty by providing more opportunities through
our Commission for Economic Opportunities; continuing to assist specific
industries through our work at the Economic Development Corporation.
This effort is intended to address new challenges for New York.
Specifically about schools, our population projections suggest that
our school-age population will not increase significantly over what
it is today. This doesn't mean that we don't need more capacity now,
and certainly some neighborhoods may need more schools. We intend
to address those needs through the planning processes at the Schools
Construction Authority. But it does mean that we don't face a Citywide
school capacity crisis for 2030, which is why we haven't identified
it as one of our sustainability goals.
How
will you be listening to New Yorkers?
This Web site provides an opportunity to give feedback and ideas on
every goal the city has announced for 2030. You can also call 311
to give your ideas or write to City Hall. Also, the city will be hosting
meetings across New York with communities, elected officials, and
other groups. Check out our calendar under "ACTIONYC" for
details of events as they get scheduled.
