The company was founded in 1997 and is headquartered in New York City. SL Green is one of the largest office landlords in New York City, with a portfolio of over 100 properties totaling more than 40 million square feet of space.

As a major player in the commercial real estate industry, SL Green is committed to sustainability and decarbonisation. The company recognizes the importance of reducing its carbon footprint and has implemented a number of initiatives to achieve this goal. One of these initiatives is the implementation of energy-efficient building systems and technologies. SL Green has invested in energy-efficient lighting, HVAC systems, and other building technologies to reduce energy consumption and lower its carbon emissions.

Another way that SL Green is working towards decarbonisation is through the use of renewable energy. The company has partnered with renewable energy providers to source renewable energy for its properties. This includes the use of solar power, wind power, and other renewable energy sources. By using renewable energy, SL Green is able to reduce its reliance on fossil fuels and lower its carbon emissions.

In addition to using renewable energy, SL Green is also exploring the use of corporate power purchase agreements (PPAs) to further decarbonize its operations. A corporate PPA is a contract between a company and a renewable energy provider that allows the company to purchase renewable energy directly from the provider. By using a corporate PPA, SL Green can secure a long-term supply of renewable energy at a fixed price, which can help the company to reduce its carbon emissions and lower its energy costs.

SL Green is also committed to corporate energy management, which involves the monitoring and management of energy use across its properties. The company has implemented a number of energy management programs to reduce energy consumption and improve energy efficiency. This includes the use of energy management software, which allows the company to track energy use and identify areas where energy can be saved.

Overall, SL Green Realty Corp. is a leader in the commercial real estate industry when it comes to sustainability and decarbonisation. The company recognizes the importance of reducing its carbon footprint and is taking proactive steps to achieve this goal. By investing in energy-efficient building systems and technologies, using renewable energy, and exploring the use of corporate PPAs, SL Green is working towards a more sustainable future.
