The China CleanTech Index outperformed all of its four benchmarks for the month of March 2015 and recorded a huge gain of 16.2%. This was driven by both strong gains across all Chinese stocks and the positive government sentiment towards environmental initiatives expressed at the National People's Congress.
The China CleanTech Index provides the April-June 2014 quarterly performance report. It includes: China CleanTech Index overview, China CleanTech Index performance, component sub-indicies and index component companies.
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.
The China CleanTech Index rose strongly in May 2013 to continue its strong performance for the year. Over the month, the Index outperformed all but one of its four benchmarks.
