tenets – resilience, operational excel- lence, and value creation – we achieve unprecedented results while maintaining purpose and integrity in everything we do. By focusing on ESG issues, we have effective risk-management practices in place that influence strategic deci- sions at the highest levels. Last year, we integrated our ESG platform throughout all departments of the company and leveraged these initiatives to grow our program. The result was industry-leading performance achieved across top ESG rating frameworks, including Bloomberg, ThomsonReuters, andCDP. These achieve- ments are a testament to SL Green’s commitment to transparent and sound governance. We are committed to differentiating abstract objectives from tangible solu- tions. At SLGreen, wemeasure everything – being able to quantify our portfolio’s environmental impact is essential in under- standing how it correlates with our orga- nizational objectives and in our role as New York City’s largest commercial owner. In 2019, City Council passed the Cli- mate Mobilization Act, which regulates New York City building emissions. New York State followed suit with the passing of the Climate Leadership & Community Protection Act, which established the goal of converting the state's energy to re- newable resources. In tandem, these new environmental laws present the most comprehensive framework with the ob- jective of positioning New York as a leader in urban sustainability. With our longstanding focus on opera- tional excellence, we are well positioned to meet the challenges associated with this emerging legislation. SL Green is represented at the highest levels of industry, City, and State organizations responsible for developing the blueprint of New York’s environmental future. This involvement ensures that the City and the State’s environmental goals are bal- anced with technical feasibility and economic rationality. What makes me most proud is the team we have assembled, which maintains

SL Green’s excellence day in and day out. The long-term sustainability of our company is dependent on our people. It is our priority to create a workplace environment that fosters a spirit of innovation and encourages high per- formance. We empower our employees to drive our workplace culture by implementing their valued feedback and recommendations across all levels of the company. We are introducing measurable corporate objectives for human capital aimed at attracting and retaining top talent, and continuously evaluate ways to make ourselves com- petitive in the hiring landscape. Our impact extends beyond our physi- cal footprint because the success of SL Green and New York City go hand in hand. Volunteerism and philanthropy are ingrained in SL Green’s ethos. We are committed to donating to charita- ble causes selected by our employees, with a total of $2 million in donations contributed as an organization annually. As a homegrown company, it is mean- ingful for our people to be able to enrich the lives of thousands of New Yorkers and support causes that are aligned with our values. As Chairman of the Board, I am commit- ted to upholding our reputation as a sustainable, responsible, and ethical organization. I amproud of the progress we have made as a responsible corporate citizen and will continue to be an advocate of sustained ESGmanagement.

The Bigger Picture SL Green recognizes climate change as a significant envi- ronmental challenge to the continued economic vibrancy of New York City. The IPCC (Intergovernmental Panel on Climate Change) suggests that in order to slow rising global tempera- tures, greenhouse gas emissions must be reduced. In response, New York City has committed to reduce greenhouse gas emissions 80% by 2050 , with an interim reduction of 40% by 2030 . As the largest commercial office owner in New York City, SL Green is committed to reducing greenhouse gas emissions across our portfolio. Real estate assets generate both direct and indirect greenhouse gas emissions through base building operations. Direct emis- sions (Scope 1) are generated onsite from fossil fuels used for heating and hot water. Indirect emissions (Scope 2) are generated offsite from steam and electricity supplied by local utilities. In addition to emissions generated to support base building operations, tenant energy consumption (Scope 3) contributes to the overall carbon footprint of a building. SL Green reduces Scope 1 and Scope 2 greenhouse gas emis- sions by optimizing building operations, implementing intensive energy management, and deploying capital investment in state-of-the-art equipment. But our emission reduction strategy goes beyond those under our direct control— we equip our tenants with tools to achieve Scope 3 energy reductions within their spaces. EMISSIONS MANAGEMENT

IN NEW YORK CITY, 67% OF GREENHOUSE GASES ARE EMITTED FROM BUILDINGS USING NATURAL GAS, ELECTRICITY, FUEL OIL, AND STEAM.

CARBON REDUCTION TARGETS NYC Mayor’s Carbon Challenge SL Green voluntarily participates in the New York City Mayor’s Carbon Challenge. We identified a selection of properties across 8 million square feet and have committed to a 30% reduction in Scope 1 and Scope 2 greenhouse gas emissions intensity over a 10-year period. CDP - Carbon Disclosure Project We voluntarily participate in CDP (formerly known as the Carbon Disclosure Project), an annual investor survey on climate change, which evaluates company performance and risk management strategies. To demonstrate our com- mitment to emissions management, we established a portfolio-wide green- house gas intensity reduction goal of 30% by 2025 for Scope 1, Scope 2, and Scope 3 emissions. 30% Reduction in SL Green’s greenhouse gas emissions intensity by 2025

ACHIEVING THE SLG STANDARD THROUGH CAPITAL IMPROVEMENTS Operational efficiency is a core strategy for our energy management program — it is cost-efficient, scalable portfolio-wide, and can be rapidly deployed. This best-in-class operation is enabled by our long-term investments in building infra- structure. Capital improvements increase a prop- erty’s overall value, reduce operating costs, and modernize our base building systems. An ice plant is a high efficiency cooling system that stores ice to generate chilled water for air conditioning. The ice is produced overnight during off-peak hours when the electric grid generates the fewest emissions, avoiding the demand for carbon-intensive power plants. We partnered with Trane to install the most efficient chiller on the market at 11 Madison Avenue , reducing utility costs and carbon emissions. The installation is projected to save over $14 million in utility bills and reduce the building’s carbon footprint by 1.4 million pounds of CO 2 over a 20-year period.

ENERGY OPTIMIZATION CLASS “A” OPERATION

DAY-TO-DAY Energy Management Tools BMS (Building Management System) All SL Green office properties are equipped with automated building systems that centralize the direct digital control of building systems and monitor space conditions with single-pane viewing. Real-Time Energy Management Platform We installed iES EnergyDesk in 20 million square feet of our operating properties. This software solution empowers our Engineering Team to respond to building conditions in real time by detecting irregularities, tracking occupancy, and monitoring energy use in 15-minute intervals. Load Based Optimization System (LOBOS) We deployed LOBOS at select properties to maximize efficiency and improve tenant comfort. This is an intelligent optimization tool used for large-scale air conditioning systems that automatically adjusts setpoints to optimal levels.

Environmental challenges can be managed by deploying innovative technology. At SL Green, we are laser focused on exploring commercially available solutions to optimize our day-to-day energy management program. Over the past decade, we have incorporated portfolio-wide programs and technologies that set the baseline for efficient building operations.

SL Green Chief Operating Officer, Edward V. Piccinich (right), accepting the Energy Efficiency Leader Award from Trane President of Commercial HVAC, Donald Simmons (left). We executed the installation ahead of schedule, which quali- fied us for $2.4 million in Con Ed incentives. On the heels of our success at 11 Madison, we deployed the Trane ice plant earlier this year at 220 East 42nd Street , securing $2.8 million in additional Con Ed incentives. This project will generate nearly $11 million in utility savings and reduce the building’s carbon footprint by 766,000 pounds of CO 2 over a 20-year period.

REDUCING PEAK DEMAND Demand Response Action Plan The cornerstone of our energy management platform is demand response – an event triggered by either our electric utility Con Edison (Con Ed) or the grid operator NYISO (New York Independent System Operator) – which calls for a volun- tary reduction in electric consumption. When there is a threat to grid reliability, SL Green curtails electric consumption to do our part in ensuring a stable energy system in New York City. The process begins when Con Ed or NYISO sends a curtailment notice to iES, who passes the signal through EnergyDesk to our Engineering and Property Management Teams. The Engineering Team at each property activates the property- specific response protocol, which includes powering down nonessential equipment, turning off ancillary lighting, reduc- ing elevator operations, and adjusting temperature setpoints without jeopardizing tenant comfort. In tandem, the Property Management Team notifies tenants of the changes in build- ing operation and encourages their participation to reduce energy usage.

Material Selection SL Green partners with qualified vendors and collaborates with tenants to reduce the demand on virgin resources and reuse durable materials during construction. At One Vanderbilt, steel rebar used throughout the building comprises 90% recycled content, and the concrete mix is com- posed of recycled byproducts including slag and fly ash. Organics Recycling Approximately 35% of New York City’s waste stream is composed of organics, including food waste and compostable products, which can be diverted from landfills. To address this waste reduction opportu- nity, we piloted a composting program at our corporate headquarters and diverted over 2,000 pounds of organics in a 6-month period. Electronic Waste In accordance with New York State’s Electronic Equipment Recycling and Reuse Act of 2010, SL Green implemented procedures to properly dispose electronic waste, including computers, keyboards, and bat- teries. We recycled over 5,000 pounds of electronic waste in 2018 through our complimentary program offered to tenants, preventing hazardous material from contaminating the waste stream.

SL Green manages waste and recycling operations across 21 million square feet, and has developed a coordinated logistics plan as part of our standard operating procedures. We partner with our tenants, employees, union stakeholders, and vendors to reduce the amount of waste that is sent to landfills. In one year alone, we increased our recycling rate by nearly 2%, moving closer to our corporate goal of a 50% recycling rate by 2025, which is in alignment with the LEED v4 threshold.

Operational Strategies SL Green implemented a color-coordinated recycling system to streamline proce- dures and improve source separation. We have equipped our janitorial staff with double-barrel waste bins to ensure that waste streams remain sepa- rated, from initial pick-up in tenant spaces to drop-off at the loading dock. All waste storage areas in the loading dock, freight elevator landings, and back- of-house areas are distinguished with signage that illustrates the correct hauling procedures. Tenant Engagement SL Green’s Sus- tainability Team offers annual recycling trainings to over 100,000 individuals who work in buildings across our portfolio. We offer recycling walkthroughs where we help tenants identity ways to im- prove recycling rates. We also distribute educational material and sample signage to help support tenant implementation of SL Green’s recycling program.

Ongoing Education In collaboration with SEIU Local 32BJ, over 500 of SL Green’s janitorial staff are trained on proper waste collection procedures on an annual basis. All presentations are translated into a variety of languages to ensure the material is accessible for all employees. Monthly Tracking SL Green requests monthly waste reports from our haulers to monitor and measure the effective- ness of our recycling procedures. This data is benchmarked in ENERGY STAR’s Portfolio Manager WasteTracker tool. Waste Audits In partnership with our environmental consultant, Sustainable Investment Group (SIG), SL Green’s waste stream is audited annually to identify sources of conta- mination and areas to improve recycling rates. These results are then pre- sented to Property Management and tenants to create customized corrective action plans.

Leak Detection SL Green’s engineers are responsible for visually inspecting water systems throughout our buildings to ensure they are operating under optimal conditions. We also deploy auto- matic sensors on our steam traps to notify our engineers of potential water loss. This proactive approach prevents future leaks and wasted water. Daily Monitoring Engineers review water logs daily to compare trends and identify consumption irregularities. This protocol ensures that our engineers are responding to fluctuations in system operations. Low-Flow Fixtures Our team capi- talizes on every opportunity to retrofit existing toilets, urinals, faucets, and showers with low-flow fixtures. The specifications are aligned with the LEED v4 standard of performing 20% better than code requirements. Water Tracking SL Green tracks water consumption data through ENERGY STAR’s benchmarking tool, Portfolio Manager. This data is disclosed to New York City’s Department of Buildings (DOB) to fulfill the annual reporting requirements outlined under Local Law 84 of 2009. Landscaping At SL Green, we incor- porate biophilic design into the built environment. We prioritize landscaping

that is indigenous to New York because native plants are adapted to local envi- ronmental conditions, require less water, and promote regional biodiversity. CAPTURED RAINWATER The most efficient water-saving technologies will be deployed at SL Green’s ground-up development, One Vanderbilt. This includes a water reclamation system, where rainwater will be collected, stored, and reused for our cooling towers. This reduces our demand for fresh surface water or groundwater, and is projected to save over 1 million gallons of water per year. AUTOMATED METERING The next evolution of SL Green’s water-management strategy is monitoring consumption in real time. We implemented this technology at 555 West 57th Street and 110 East 42nd Street, and plan to deploy this across five additional properties by the first quarter of 2020.

Water scarcity is a key environ- mental issue, and SL Green is leading by example through our responsible water manage- ment program. Our strategy includes installing low-flow fix- tures, encouraging responsible resource management among building operators and tenants, and monitoring consumption data across 100% of our owned and managed portfolio. Fixture upgrades decreased our water consumption by 30% across the LEED certified buildings in our Manhattan portfolio, equivalent to saving 29 million gallons of water per year.

>1,000 SL Green Paid Employee Volunteer Hours VOLUNTEERISM At SL Green, we are only as strong as the com- munities in which we operate. The importance of community engagement is twofold — it strengthens local resiliency and provides social growth opportunities for our employees outside of the office. Our employees, assets, and business deliver the best results when they are integrated into the community and contribute positively to a greater societal purpose. Park Cleanup Every year SL Green employees celebrate Earth Day by cleaning up our backyard in New York City parks. Together with the Mayor’s Office and our tenants, we pick up litter, repaint infrastructure, and replant flowers and trees. American Corporate Partners Veteran Mentorship SL Green employees volunteer in a mentorship program to provide post-9/11 veterans with resumé review, interview prepa- ration, career exploration tips, and networking opportunities. Mentorship Program SL Green hosted 25 students from Robert F. Wagner Junior Secondary School, where the student- to-college-advisor ratio is 500:1. SL Green’s team dedicated it's time to empower New York’s future workforce by helping students with interviewing skills, resumé writing, and career counseling. Ladders for Leaders Since 2016, SL Green has partnered with the New York City Mayor’s Office to provide students with internship opportunities that develop workplace readiness skills and business etiquette.

Affordable Housing At SL Green’s ground-up residential development, 185 Broad- way, 30% of the newly constructed units will be rent regulated to ensure the affordability of housing on New York City’s rental market.
