PlaNYC 2030
• New York City’s
long-term plan for the
year 2030
• Anticipates 1 million
more residents from
2005 to 2030
• GOAL: Reduce CO2
emissions 30% by
2030
• “Will you still love
New York in 2030?”
PlaNYC 2030
• Land – 10-minute walk
from a park
• Water – swimmable
• Transportation – public
• Energy – existing
buildings
• Air – quality
• Climate Change –
building resilience
PlaNYC 2030
Buildings account for 75-80% of NYC’s carbon
emissions
85% of building stock anticipated in 2030 existed
in 2005 – focus on existing buildings
Five Boroughs
578 miles of coastline
305 sq mi of land area
– 54% is built area
– 41% are roads, open space, and
water ways
– 5% available for development
Greener, Greater Buildings Plan
6-Point Plan
#1 - New York City Energy Conservation Code
• 3 laws affecting buildings > 50,000 GSF
#2 - Benchmarking
#3 - Audits and Retrocommissioning
#4 - Lighting Upgrades / Sub-Metering
#5 - Financing assistance
#6 - Green workforce development
3 LAWS: BUILDINGS > 50K GSF
Green Codes Task Force

Mayoral Task Force
develop 111 “greening”
measures for
Construction Codes,
Zoning Resolution and
other regulations:
To date these have
resulted in 16 laws and
regulations, with
anticipated completion
by close of 2013
