Who Are We?
Trusted advisors in compliance, retrospective cost savings, and procurement.
Global Sustainability is a forward-thinking energy consulting firm dedicated to helping
building managers reduce emissions, cut operational costs, and comply with evolving
local laws like NYC’s Local Law 97 and 88.
We specialize in energy procurement, real-time monitoring, compliance consulting, and
retrospective cost recovery. Our team brings together deep technical expertise, data-
driven insights, and a commitment to long-term value. We want to empower building
owners and managers to operate smarter, cleaner, and profitably.
Local Law 97 Consulting
Plan smarter. Comply faster. Avoid penalties.
Local Law 97 is one of New York City’s most ambitious climate laws, requiring buildings over 25,000 square feet to reduce greenhouse gas emissions or face substantial fines starting in 2024 and tightening in 2030. Compliance isn’t optional, it is critical.
Services include:
● Understand emissions limits and how they apply to your property.
● Develop actionable compliance roadmaps
● Identify cost-effective upgrades
● Install monitoring tools to endure ongoing compliance
● Establish fail-safe systems to avoid penalties and stay ahead of future deadlines
Retrospective
Your building’s past holds the key to future savings.
We identify and recover overcharges, inefficiencies, and missed opportunities from past utility expenses. Our retrospective audits don’t just identify what went wrong – they put safeguards in place to ensure your energy costs stay optimized going forward.
Services include:
● Recover lost savings from billing errors
● Analyze historical consumption to uncover inefficiencies
● Correct contract discrepancies
● Implement ongoing monitoring to prevent future losses
● Establish fail-safe systems to flag anomalies before they become costly
Procurement
High-efficiency solutions, sourced with precision.
We provide a strategic approach businesses can use to reduce operational costs, enhance efficiency, manage risks, and ensure continuity with fail-safe strategies.
Services include:
● Securing competitive rates through supplier negotiations
● Optimize energy consumption
● Manage market risks
● Leverage real-time data for smarter decision-making
● Ensure continuity with fail-safe strategies like fixed-rate protections and backup energy systems
