Amgen Inc. is a leading biotechnology company headquartered in Thousand Oaks, California, United States of America. The company was founded in 1980 by William K. Bowes Jr. and George B. Rathmann, and it has since become one of the largest biotech companies in the world. Amgen's mission is to serve patients by discovering, developing, and delivering innovative human therapeutics. The company's product portfolio includes biologic medicines for the treatment of cancer, cardiovascular disease, bone health, and other serious illnesses.

Amgen's commitment to sustainability is evident in its efforts towards decarbonisation and renewable energy. The company recognizes the urgent need to reduce greenhouse gas emissions and mitigate the effects of climate change. In 2020, Amgen announced its goal to achieve carbon neutrality across its global operations by 2027. This ambitious target includes a 40% reduction in emissions by 2025, using a 2016 baseline.

To achieve its decarbonisation goals, Amgen is implementing a range of initiatives, including energy efficiency improvements, onsite renewable energy generation, and the use of renewable energy certificates (RECs) and carbon offsets. The company is also exploring the use of corporate power purchase agreements (PPAs) to procure renewable energy directly from wind and solar farms. PPAs are long-term contracts between a company and a renewable energy provider, which guarantee a fixed price for electricity over a specified period. By entering into PPAs, Amgen can support the development of new renewable energy projects and reduce its reliance on fossil fuels.

Amgen's commitment to renewable energy is also evident in its corporate energy strategy. The company has set a goal to source 100% of its electricity from renewable sources by 2025, and it is making progress towards this target. In 2020, Amgen sourced 55% of its electricity from renewable sources, up from 40% in 2019. The company is also investing in onsite renewable energy generation, such as solar panels and fuel cells, to reduce its reliance on grid electricity.

In addition to its decarbonisation and renewable energy efforts, Amgen is also committed to reducing its overall energy consumption. The company has implemented a range of energy efficiency measures across its operations, including lighting upgrades, HVAC improvements, and the use of energy-efficient equipment. These measures not only reduce Amgen's carbon footprint but also help to lower its operating costs and improve its bottom line.

Overall, Amgen's commitment to sustainability is evident in its efforts towards decarbonisation and renewable energy. The company recognizes the urgent need to reduce greenhouse gas emissions and mitigate the effects of climate change, and it is taking action to achieve its ambitious goals. By investing in renewable energy, energy efficiency, and corporate PPAs, Amgen is not only reducing its carbon footprint but also demonstrating its commitment to a sustainable future.
