NYC GHG Inventory and Carbon Mitigation Strategy City Climate Leadership Awards
September 5, 2013
Mayor Bloomberg released PlaNYC in 2007, a comprehensive sustainability plan to create a greener, greater New York City. The 2011 Update focuses on 10 issues:
Housing and Neighborhoods Parks and Public Space
Brownfields Waterways Water Supply
Transportation Energy Air Quality Solid Waste Climate Change
The culminating goal of PlaNYC is to reduce citywide greenhouse gas emissions by 30% from 2005 levels by 2030.

You can’t manage what you can’t measure. New York City has conducted annual GHG emissions inventories since 2007 •
Citywide GHG emissions
•
Emissions from City government facilities and operations
•
Updates reflect new or revised data and updated methodologies
New York City tracks GHG emissions by sector and source

Calculating GHG Emissions from Electricity NYC calculates its own electricity emissions coefficient •
Power plant emissions data from U.S. databases
•
Information from local utilities •
Total electricity demand
•
Contracts for imported electricity
•
Steam generation
2011 Results: NYC’s GHG emissions are 16% below 2005 levels 2005 Baseline
Changes in the electricity supply account for 68% of the decrease in GHG emissions since 2005

New York City has five major initiatives to help mitigate GHG emissions from buildings The Greener, Greater Buildings Plan • Comprehensive plan to increase the efficiency of NYC’s largest buildings
NYC Green Codes Task Force • 111 proposals to green local building codes, with 51 aimed at reducing energy use
30x17 and Mayor’s Carbon Challenge 30x17
3017
• City government and targeted sectors will achieve accelerated GHG reductions of 30% in 10 years
NYC Clean Heat • Regulations and assistance to eliminate heavy heating oil in NYC
GreeNYC • Public engagement arm of PlaNYC to encourage behavior change
The Greener, Greater Buildings Plan Landmark package of laws to address 13,000 large properties that make up half of the city’s square footage and 45% of the energy used in buildings.

Benchmarking
Audits and Retro-commissioning
Lighting Upgrades and Submetering
More than 2 billion square feet of space has undergone benchmarking. Citywide Energy Use by Sector
Source Energy Use Intensity (EUI) in Large Buildings

Results •
The highest energy users consume 3-5 times more energy than lowest energy users
•
Reaching average energy use would reduce citywide GHG emissions by 9%
Up Next: Mandatory energy audits and retro-commissioning, beginning 2013
Resources were developed to support the Greener, Greater Buildings Plan • FINANCING: New York City Energy Efficiency Corporation • Provides $37 million in loan products for energy efficiency retrofits • www.nyceec.com • LEASE LANGUAGE: Energy Aligned Clause • Solves the “split incentive” problem for commercial leases • www.nyc.gov/eac • OUTREACH AND EDUCATION: Green Light New York • Provides trainings for code compliance, benchmarking, auditing, lighting, etc. • www.greenlightny.org
The Mayor’s Carbon Challenge Certain sectors are voluntarily reducing building-based GHG emissions at an accelerated pace.

Eliminating the Use of Heavy Heating Oil Eliminating No.6 heating oil will reduce GHG emissions by more than 1 million metric tons and is one of the highest impact strategies to improve air quality.
Heating Oil Regulations •
Phase out No. 6 oil by 2015
•
All buildings on cleanest fuels by 2030
NYC Clean Heat Program •
Information
•
Technical assistance
•
Financing & incentives
Outcomes •
Completed over 2,000 oil conversions
•
Halfway to goal to reduce PM2.5 by 50%
•
Reaching goal will save ~120 lives and prevent ~300 hospital visits each year
GreeNYC: New York City’s public engagement arm Approach to engaging residents: • Strong brand
• Data-driven campaign content • Strategic messaging • Traditional and city-owned media • Unify the City’s voice • Develop NGO and private sector partnerships
Behavior change can achieve significant GHG reductions Consumer Study 1. Which actions will have the biggest impact on the environment? 2. What messages are most effective? 3. How can we measure our success? Top PlaNYC Levers for Reducing GHG Emissions
Top 10 Actions to Reduce GHG Emissions
1. Replace car with hybrid 2. Switch to energy produced from cleans sources 3. Perform a home energy audit 4. Replace car with electric
5. Weatherize your home 6. Air dry clothes and use cold water to wash 7. Replace light bulbs 8. Eat produce in season 9. Turn down thermostat in winter 10.Regularly tune up car
Monitoring and Evaluation Example: Anti-Idling Campaign GreeNYC campaign media tagged “To report idling, call 311.” Call Service experienced a 111% increase in calls about idling during period of the campaign
