CASE STUDY

CASE STUDY

MIYA: ENSURING A SUSTAINABLE WATER SUPPLY Water management company Miya recently announced a partnership in Portugal to develop a water efficiency project with a per formance-based contract that will prevent water losses of 1.4 billion litres. The project, based in the municipality of Chaves, will save the local government €2.3 million and allow the town to continue to generate monetary and water savings beyond the life of the contract, which ends in 2026. Since almost all of Miya’s Portuguese subsidiary’s revenue depends on its performance, the investment risk lies with the company, and not the municipality of Chaves. This performance-based approach ensures a win-win-win for Miya, the town and its people, and the environment.

CITYFIBRE: DIVERSIFYING AN INDUSTRY UK-based CityFibre has committed to promoting diversity, equity, and inclusion (DEI) in a historically homogenous industry. To achieve this, the company established an employee led Gender Network to create a space for gender issues and equality to be discussed without judgement, challenge existing bias, and advocate for measurable change. It also launched the Aspiring Managers Programme and a mentoring scheme, both of which serve to support the career development of women in the business. Illustrating the progress being made, a recent staff survey showed that 93% of women at CityFibre would recommend it as a place to work to others. As further testament to the success of its strategy, CityFibre was named a Times Top 50 Employer for Women in 2021. The company also publishes a public gender pay gap report, which shows that its wage disparity has rapidly shrunk over the past three years. Exemplifying the company's leadership in this area, CityFibre presented on its DEI strategy at Antin’s annual ESG Club meeting in December 2021 to allow other representatives from across the portfolio to learn from its best practices.
