A message from our Chairman & Chief Executive Officer.

SL Green has sustained its prominent position in New York City real estate by employing a pioneering business strategy supported by core values. We assembled a portfolio that creates long-term value and is responsive to dynamic market conditions. The transformative evolution of SL Green since our initial public offering two decades ago has been momentous, as every aspect of the company has grown in sophistication, efficiency, and adaptability. Corporate Social Responsibility is no exception, and the principles of Environmental, Social, and Governance (ESG) are integral to our success.

“The principles of Environmental, Social, and Governance (ESG) are integral to our success.”

Marc Holliday
Chairman & Chief Executive Officer

The growing importance of socially responsible investing means that ESG performance is inextricably linked with financial performance. At SL Green, the imperative to deliver value to shareholders has always been at the forefront of how we conduct our business. And because of our commitment to our core tenets – resilience, operational excellence, 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 decisions 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, Thomson Reuters, and CDP. These achievements are a testament to SL Green’s commitment to transparent and sound governance.

We are committed to differentiating abstract objectives from tangible solutions. At SL Green, we measure everything – being able to quantify our portfolio’s environmental impact is essential in understanding how it correlates with our organizational objectives and in our role as New York City’s largest commercial owner.

In 2019, City Council passed the Climate 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 renewable resources. In tandem, these new environmental laws present the most comprehensive framework with the objective of positioning New York as a leader in urban sustainability.

With our longstanding focus on operational 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 balanced 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 performance.

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 competitive in the hiring landscape.

Our impact extends beyond our physical 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 charitable causes selected by our employees, with a total of $2 million in donations contributed as an organization annually.

As a homegrown company, it is meaningful 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 committed to upholding our reputation as a sustainable, responsible, and ethical organization. I am proud of the progress we have made as a responsible corporate citizen and will continue to be an advocate of sustained ESG management.

A message from our Director of Sustainability.

Green buildings are no longer the exception, they’re the rule. At SL Green, we believe that a strategy for environmental stewardship must also address economic growth and development in order for it to be sustainable. As New York City’s largest commercial landlord, we can make a significant impact by stabilizing our carbon footprint.

Now, more than ever, it is essential that real estate owners and managers work in partnership with local and federal governments to shape policies that yield both environmental and economic benefits. But our vision alone won’t change the world.

Environmental challenges are best solved by encouraging human ingenuity and developing cutting-edge technologies. As a leader in commercial real estate, SL Green is committed to implementing best practices and operating at the highest efficiency standards to strengthen our community’s resiliency, while maintaining our responsibility to our shareholders.

For over 20 years, the fortunes of New York City and SL Green have been intertwined. Our company is built on the highest standard of integrity and a pioneering spirit. Together we can influence New York City’s environmental future.

Our Tenants

We’re delivering real results for the people under our roofs and, through our energy-efficiency initiatives, we’re providing extra value.

“Our partnership with the SL Green team focuses on saving energy at the building level, which in turn allows us as tenants to do our very best to conserve natural resources. This is important to us because we’re partnering with an organization that has the same philosophy we do by promoting sustainability.”

Kim Schutz
Associate Director of Operations of KPMG

“Working with SL Green has allowed us to implement energy efficiency projects that, as a tenant, we did not anticipate in our build-out. For instance, they’ve recently installed variable frequency drives and, although this was an SL Green initiative, we worked collaboratively to understand the benefits. In fact, we accrue the energy savings from many of SL Green’s projects through the realization of lower energy bills.”
