Marriott International is a global hospitality company that operates in the Room Revenue - Hotels sector. Founded in 1927, the company has grown to become one of the largest hotel chains in the world, with over 7,600 properties in 133 countries and territories. Marriott International is committed to sustainability and has set ambitious goals to reduce its environmental impact, including decarbonisation and increasing the use of renewable energy.

One of the key areas where Marriott International is focusing its sustainability efforts is in decarbonisation. The company has set a goal to reduce its greenhouse gas emissions by 30% by 2025, compared to 2019 levels. To achieve this goal, Marriott International is implementing a range of measures to reduce energy consumption and increase the use of renewable energy.

One of the ways that Marriott International is reducing its energy consumption is through the implementation of corporate energy initiatives. The company has implemented a range of energy efficiency measures across its properties, including the installation of LED lighting, the use of energy-efficient HVAC systems, and the implementation of smart building technologies. These measures have helped Marriott International to reduce its energy consumption and save money on energy costs.

In addition to energy efficiency measures, Marriott International is also increasing the use of renewable energy. The company has set a goal to source 50% of its electricity from renewable sources by 2025, and is working to achieve this through the implementation of corporate power purchase agreements (PPAs). These agreements allow Marriott International to purchase renewable energy directly from wind and solar farms, providing a reliable and cost-effective source of renewable energy.

Marriott International has already signed several corporate PPAs, including a 15-year agreement to purchase energy from a wind farm in Texas. This agreement will provide Marriott International with 90,000 megawatt-hours of renewable energy each year, enough to power over 8,000 homes. Marriott International has also signed a PPA to purchase energy from a solar farm in California, which will provide the company with 30,000 megawatt-hours of renewable energy each year.

In addition to corporate PPAs, Marriott International is also investing in on-site renewable energy projects. The company has installed solar panels at several of its properties, including the Marriott Marquis Washington, DC and the JW Marriott Desert Springs Resort & Spa. These projects help to reduce the properties' reliance on grid electricity and provide a reliable source of renewable energy.

Overall, Marriott International is committed to sustainability and is taking a proactive approach to reducing its environmental impact. The company's focus on decarbonisation, corporate energy initiatives, corporate PPAs, and renewable energy is helping to reduce its greenhouse gas emissions and move towards a more sustainable future. As a global leader in the hospitality industry, Marriott International is setting an example for other companies to follow and demonstrating that sustainability can be both good for the environment and good for business.
