Marsh & McLennan Companies (MMC) is a leading professional services firm that operates in the insurance brokers and services sector. The company is headquartered in New York City and has operations in over 130 countries worldwide. MMC provides a wide range of services to clients, including risk management, insurance brokerage, reinsurance, consulting, and technology solutions.

MMC is committed to decarbonisation and reducing its carbon footprint. The company has set a target to reduce its greenhouse gas emissions by 15% by 2025, compared to 2019 levels. To achieve this goal, MMC is implementing a range of initiatives, including energy efficiency improvements, renewable energy procurement, and the use of low-carbon transportation options.

One of the key ways that MMC is reducing its carbon footprint is through corporate energy management. The company has implemented a range of energy efficiency measures across its global operations, including lighting upgrades, HVAC system improvements, and the installation of energy-efficient equipment. These measures have helped to reduce the company's energy consumption and carbon emissions.

MMC is also actively pursuing renewable energy solutions to power its operations. The company has signed several corporate power purchase agreements (PPAs) to procure renewable energy from wind and solar projects. These agreements enable MMC to purchase renewable energy at a fixed price over a long-term period, providing price stability and reducing the company's exposure to energy price volatility.

In 2020, MMC signed a 10-year PPA with Enel Green Power North America for 90 MW of renewable energy from the Azure Sky wind project in Texas. The project is expected to generate over 350,000 MWh of renewable energy annually, which is equivalent to the energy consumption of over 30,000 homes. This PPA will enable MMC to reduce its carbon footprint by over 70,000 metric tons of CO2e annually, which is equivalent to taking over 15,000 cars off the road each year.

MMC is also exploring other renewable energy solutions, such as onsite solar installations and energy storage systems. The company has installed solar panels at several of its offices, including its headquarters in New York City, which has a 40 kW solar array. MMC is also exploring the use of energy storage systems to store excess renewable energy generated onsite, which can be used to power the company's operations during times of high energy demand or when renewable energy generation is low.

In addition to its own corporate energy management initiatives, MMC is also helping its clients to transition to renewable energy and reduce their carbon footprint. The company's consulting and advisory services help clients to identify and implement energy efficiency measures, procure renewable energy, and develop sustainability strategies. MMC's expertise in renewable energy and sustainability has helped many clients to achieve their decarbonisation goals and reduce their environmental impact.

Overall, MMC is a leader in the insurance brokers and services sector when it comes to decarbonisation and corporate energy management. The company's commitment to reducing its carbon footprint and transitioning to renewable energy is commendable, and its efforts to help clients achieve their sustainability goals are making a positive impact on the environment. MMC's focus on renewable energy and sustainability is a testament to its commitment to building a more sustainable future for all.
