Appen was founded in 1996 by Dr. Julie Vonwiller and Mark Brayan. The company started as a small business providing language resources to the speech technology industry. Over the years, Appen has grown into a global organization with over 1,400 employees and contractors in more than 130 countries. The company is headquartered in Sydney, Australia, with offices in the United States, the United Kingdom, and the Philippines.

Appen's services are designed to help businesses and organizations improve their data quality, increase their efficiency, and reduce their costs. The company's data annotation services are used to train machine learning algorithms, while its data collection services are used to gather information from various sources. Appen's data analysis services help businesses make sense of their data, providing insights that can be used to improve their operations.

In recent years, Appen has also been focusing on decarbonisation and renewable energy. The company has made a commitment to reduce its carbon footprint and become more environmentally sustainable. As part of this commitment, Appen has implemented a number of initiatives aimed at reducing its energy consumption and increasing its use of renewable energy.

One of the key initiatives that Appen has implemented is the use of corporate power purchase agreements (PPAs) for renewable energy. Corporate PPAs allow businesses to purchase renewable energy directly from renewable energy projects, such as wind farms or solar power plants. By entering into a PPA, businesses can secure a long-term supply of renewable energy at a fixed price, which can help them reduce their energy costs and their carbon footprint.

Appen has entered into several corporate PPAs for renewable energy, including agreements to purchase wind and solar power from projects in Australia and the United States. The company has also installed solar panels on the roof of its Sydney headquarters, which generate renewable energy to power the building.

In addition to its use of corporate PPAs, Appen has also implemented a number of energy efficiency measures to reduce its energy consumption. The company has installed energy-efficient lighting and heating systems, as well as motion sensors to turn off lights and equipment when they are not in use. Appen has also implemented a program to encourage employees to reduce their energy consumption, providing them with tips and incentives to save energy.

Appen's commitment to decarbonisation and renewable energy is not only good for the environment, but it also makes good business sense. By reducing its energy consumption and using renewable energy, Appen can reduce its operating costs and improve its bottom line. In addition, Appen's focus on sustainability can help the company attract and retain customers who are looking for environmentally responsible business partners.

Overall, Appen is a leading provider of data solutions that help businesses make informed decisions. With a focus on artificial intelligence and machine learning, the company's services are designed to improve data quality, increase efficiency, and reduce costs. In addition, Appen's commitment to decarbonisation and renewable energy demonstrates its dedication to sustainability and responsible business practices. As the world becomes increasingly focused on sustainability, Appen is well-positioned to help businesses navigate this new landscape and achieve their sustainability goals.
