With over 160 companies falling under the coverage of the Index and with a combined market capitalisation of over 2.2 trillion Renminbi (US$370 billion), the China CleanTech Index presents a picture of the Chinese cleantech industry's growth in a single measure.
The combined investment themes of China and environment provide a compelling case for investment. The sector remains volatile as it matures and reacts to environmental and industry development policy shifts. The quality and scale of the companies included in the sector varies widely and strong research into both sub-sectors and companies is essential before committing to the sector.
The cleantech sector is fundamentally different to Socially Responsible Investments (SRI) or Environmental, Social and Governance (ESG) performance. SRI and ESG look at incremental improvements in company performance and can be seen as 'operational hygiene' measures that find the best in class. Cleantech focuses on companies whose output positively enhances the communities and ecologies in which they reside. It is about doing 'more good' rather than 'less bad'.
The China CleanTech Index provides the definitive measure of the performance of Chinese cleantech companies that are listed on stock exchanges around the world.
