EY, formerly known as Ernst & Young, is a multinational professional services firm headquartered in London, United Kingdom. The company operates in the Other Professional Services sector and offers a wide range of services including audit, tax, consulting, and advisory services to clients across the globe. EY is one of the largest professional services firms in the world, with a workforce of over 300,000 employees in more than 150 countries.

Decarbonisation is a key focus area for EY, as the company recognizes the urgent need to reduce carbon emissions and mitigate the impact of climate change. EY has set ambitious targets to reduce its own carbon footprint and has committed to becoming a carbon-neutral organization by 2025. The company is also working with clients to help them achieve their decarbonisation goals and transition to a low-carbon economy.

One of the ways in which EY is helping clients to decarbonize is through its corporate energy services. EY offers a range of energy management services to help clients optimize their energy usage, reduce costs, and improve their environmental performance. This includes energy audits, energy efficiency assessments, and the development of energy management strategies.

In addition to energy management, EY is also helping clients to transition to renewable energy sources through its corporate power purchase agreement (PPA) services. A corporate PPA is a long-term contract between a company and a renewable energy provider, which allows the company to purchase renewable energy directly from the provider. This enables companies to reduce their carbon footprint and secure a reliable, cost-effective source of renewable energy.

EY has significant expertise in the corporate PPA market and has helped numerous clients to secure renewable energy contracts. For example, EY worked with a major pharmaceutical company to secure a 15-year PPA for a wind farm in Scotland, which will provide the company with 50% of its UK electricity needs. EY also worked with a global technology company to secure a PPA for a solar project in India, which will provide the company with 80% of its electricity needs in the country.

EY is also helping clients to finance renewable energy projects through its renewable energy advisory services. EY provides financial and technical advice to clients looking to invest in renewable energy projects, including wind, solar, and biomass. This includes project feasibility assessments, financial modeling, and risk analysis.

EY is committed to driving the transition to a low-carbon economy and has set ambitious targets to reduce its own carbon footprint. The company has implemented a range of initiatives to reduce its energy usage and increase its use of renewable energy sources. For example, EY has installed solar panels on the roof of its London office, which generate around 10% of the building's electricity needs. The company has also implemented energy-efficient lighting and heating systems, and has introduced a range of measures to encourage employees to reduce their energy usage.

In addition to its own decarbonisation efforts, EY is also working to raise awareness of the importance of decarbonisation among its clients and stakeholders. The company regularly publishes thought leadership reports and hosts events on the topic of decarbonisation and the transition to a low-carbon economy. EY is also a founding member of the Climate Group's RE100 initiative, which brings together companies committed to using 100% renewable energy.

In conclusion, EY is a leading professional services firm that is committed to driving the transition to a low-carbon economy. The company offers a range of services to help clients decarbonize, including energy management, corporate PPA, and renewable energy advisory services. EY is also taking significant steps to reduce its own carbon footprint and raise awareness of the importance of decarbonisation among its clients and stakeholders. With its expertise and commitment to sustainability, EY is well-positioned to help clients navigate the challenges of the transition to a low-carbon economy and achieve their decarbonisation goals.
