Alumina Ltd is an Australian-based company that operates in the aluminum sector. The company was established in 2003 and is headquartered in Southbank, Victoria, Australia. Alumina Ltd is one of the world's largest producers of alumina, which is the primary raw material used in the production of aluminum. The company has operations in Australia, Brazil, and Guinea.

Alumina Ltd is committed to decarbonisation and reducing its carbon footprint. The company has set a target to reduce its greenhouse gas emissions by 30% by 2030. Alumina Ltd is working towards achieving this target by investing in renewable energy and implementing energy efficiency measures across its operations.

One of the ways Alumina Ltd is reducing its carbon footprint is through corporate energy procurement. The company has signed a corporate power purchase agreement (PPA) with a renewable energy provider to source a portion of its energy needs from renewable sources. The PPA allows Alumina Ltd to purchase renewable energy at a fixed price, which provides price certainty and reduces the company's exposure to volatile energy prices.

Alumina Ltd is also investing in renewable energy projects to reduce its reliance on fossil fuels. The company has invested in a wind farm in Brazil, which will provide renewable energy to its operations in the country. The wind farm is expected to generate 90,000 MWh of renewable energy per year, which will reduce Alumina Ltd's greenhouse gas emissions by 80,000 tonnes per year.

In addition to its renewable energy investments, Alumina Ltd is also implementing energy efficiency measures across its operations. The company has implemented a range of initiatives to reduce its energy consumption, including upgrading equipment, improving process efficiency, and implementing energy management systems.

Alumina Ltd's commitment to decarbonisation and renewable energy has been recognised by the Carbon Disclosure Project (CDP). The company has been awarded an A- rating for its climate change disclosure and has been included in the CDP's Climate A List for three consecutive years.

Alumina Ltd's commitment to decarbonisation and renewable energy is not only good for the environment but also for the company's bottom line. The company's investments in renewable energy and energy efficiency measures have reduced its energy costs and improved its operational efficiency.

In conclusion, Alumina Ltd is a leading player in the aluminum sector, with a strong commitment to decarbonisation and renewable energy. The company's investments in renewable energy and energy efficiency measures are not only good for the environment but also for its bottom line. Alumina Ltd's commitment to decarbonisation and renewable energy has been recognised by the CDP, and the company is well-positioned to continue to lead the way in sustainable business practices.
