McDonald's Corporation is a global fast food chain that operates in over 100 countries, including the United States of America. The company is known for its signature menu items such as the Big Mac, Quarter Pounder, and the iconic golden fries. McDonald's has been in operation for over 60 years and has become a household name in the fast food industry.

In recent years, McDonald's has taken significant steps towards decarbonisation and reducing its carbon footprint. The company has set ambitious sustainability goals, including sourcing 100% of its coffee, palm oil, and fish from sustainable sources by 2020. Additionally, McDonald's has committed to reducing greenhouse gas emissions by 36% by 2030, compared to its 2015 baseline.

One of the ways McDonald's is achieving its sustainability goals is through corporate energy management. The company has implemented energy-efficient practices across its restaurants, including LED lighting, high-efficiency kitchen equipment, and HVAC systems. These measures have resulted in a significant reduction in energy consumption and associated carbon emissions.

McDonald's has also implemented corporate power purchase agreements (PPAs) to increase its use of renewable energy. PPAs allow companies to purchase renewable energy directly from a generator, often at a lower cost than traditional energy sources. In 2019, McDonald's signed two virtual PPAs for wind and solar energy, which will provide the company with 380 MW of renewable energy annually. This is equivalent to the energy needed to power over 2,500 restaurants in the United States.

In addition to PPAs, McDonald's has also invested in on-site renewable energy generation. The company has installed solar panels on several of its restaurants, which generate clean energy and reduce the restaurant's reliance on the grid. McDonald's has also implemented a pilot program to test the use of biogas, a renewable energy source produced from organic waste, to power its restaurants.

McDonald's has also taken steps to reduce its waste and increase recycling. The company has set a goal to recycle 100% of its packaging by 2025 and has implemented a packaging design that uses fewer materials and is easier to recycle. McDonald's has also launched a pilot program to test reusable cups and containers in select restaurants.

Overall, McDonald's is committed to sustainability and decarbonisation, and is taking significant steps to reduce its carbon footprint. The company's efforts to increase its use of renewable energy, implement energy-efficient practices, and reduce waste are commendable and demonstrate its commitment to sustainability. As a global leader in the fast food industry, McDonald's is setting an example for other companies to follow in their pursuit of sustainability.
