Hong Kong companies are ranked top in Asia in terms of corporate communication, according to a regional report. CSR Asia released its first Asia Business Barometer report yesterday comparing the disclosure of corporate social responsibility information by the 20 largest listed companies in four Asian economies - Hong Kong, Malaysia, Singapore and Thailand. The companies' rankings were based on 62 indicators of corporate social responsibility. With an average score of 42 per cent, Hong Kong companies outperformed the others across all indicators. Malaysian companies scored an average of 29 per cent, Thai companies 25 per cent and Singaporean companies 24 per cent. Five Hong Kong blue-chip companies were ranked in the top five: CLP Holdings HSBC, China Mobile, Hang Seng Bank and PetroChina. MTR Corporation ranked eighth. Siam Cement in Thailand, City Developments and SembCorp Industries in Singapore, and BAT Malaysia and Telekom Malaysia completed the top 10. CSR Asia, a consultancy and research company, gathered information from annual reports, corporate websites, press releases, brochures and presentations. 'It is about how much information is being disclosed by companies,' CSR Asia chairman Richard Welford said. 'It is disclosure and reporting of their corporate social responsibility activities in a full and transparent way. 'We looked at 80 of the biggest companies across Asia and looked at who was reporting the most. Hong Kong did quite well.' Although Hong Kong companies performed well against regional neighbours, most companies listed in the four countries had significant room for improvement, the report said. Malaysia, which came second to Hong Kong, had made a lot of effort to develop a strong, strategic approach to corporate social responsibility, but this had not shown up in CSR Asia's research.
