Yandex is a Russian multinational corporation that specializes in internet-related products and services. Founded in 1997, the company has grown to become one of the largest internet companies in Russia and the world. Yandex operates in a variety of sectors, including search engines, online advertising, e-commerce, ride-hailing, and cloud computing. The company's revenue model is primarily based on advertising, with the majority of its revenue coming from contextual advertising.

In recent years, Yandex has made a commitment to decarbonisation and renewable energy. The company has set ambitious goals to reduce its carbon footprint and transition to renewable energy sources. Yandex recognizes that climate change is a global challenge that requires urgent action, and the company is committed to doing its part to address this issue.

One of the ways that Yandex is working towards decarbonisation is through its corporate energy strategy. The company has implemented a number of measures to reduce its energy consumption and increase the efficiency of its operations. For example, Yandex has invested in energy-efficient data centers and servers, which have helped to reduce the company's energy consumption and carbon emissions. In addition, Yandex has implemented a number of energy-saving measures in its offices and other facilities, such as LED lighting and motion sensors.

Another key part of Yandex's decarbonisation strategy is its use of corporate power purchase agreements (PPAs). A corporate PPA is an agreement between a company and a renewable energy provider, in which the company agrees to purchase a certain amount of renewable energy over a set period of time. By entering into these agreements, companies like Yandex can help to drive demand for renewable energy and support the growth of the renewable energy sector.

Yandex has signed a number of corporate PPAs with renewable energy providers in Russia and other countries. These agreements have helped to increase the share of renewable energy in Yandex's energy mix and reduce the company's carbon footprint. For example, in 2020, Yandex signed a PPA with a wind farm in the Rostov region of Russia, which will provide the company with 100% renewable energy for its data center in the region.

Yandex is also investing in renewable energy projects directly. The company has launched a number of solar power projects in Russia, including a 1 MW solar power plant in the Moscow region. These projects not only help to reduce Yandex's carbon footprint but also contribute to the development of the renewable energy sector in Russia.

Overall, Yandex's commitment to decarbonisation and renewable energy is an important step towards addressing the global challenge of climate change. By implementing energy-saving measures, signing corporate PPAs, and investing in renewable energy projects, Yandex is demonstrating its leadership in this area and setting an example for other companies to follow. As the world continues to transition to a low-carbon economy, companies like Yandex will play a critical role in driving this transition and helping to create a more sustainable future for all.
