Reuse
• 80% reduction in GHG emissions by 2050
• Carbon neutrality in new 1.5 degree Celsius Plan
• Energy-neutral wastewater treatment plants by 2050
• Maximize digester gas production
• Maximize digester gas beneficial use
• Minimize digester gas fugitive emissions
• 100 MW of solar on City-owned properties by 2025
• Zero waste to landfills by 2030
• Maximize biosolids beneficial use
• Maximize food waste beneficial use
• 50 MW enrolled in Demand Response Program by 2017
Citywide Drivers for Change
How NYC Agencies Will Reach 80x50
• DEP is a major player in citywide DR efforts:
• Historical commitment of 16-20 MW and performance of 120% or greater.
• Has accounted for as much as ~10% of citywide reductions during events.

• Sequestration by green infrastructure, wetlands, and watershed
• Energy Conservation Measures:
• Energy audits completed at WWTPs. Developing plan to integrate ECMs
into State-of-Good-Repair capital projects.
• Analytics, Education, and Accountability:
• Ensuring data is clean and reliable. Creating performance metrics.
Tracking progress of project implementation. Energy in employee reviews.
Energy reports and meetings increase transparency. Training and classes.
• Design Guidelines:
• Update and implement for more energy-efficient alternatives.
Energy Profile Report for each new or reconstruction project.
• Others:
• Incentivizing fixture replacements and water reduction challenges.
