CITY Developments Ltd (CDL) deputy chairman and executive director Kwek Leng Joo, 62, has died in his sleep on Monday morning due to a sudden heart attack.

He is the younger brother of billionaire Kwek Leng Beng, executive chairman of CDL.

As an advocate of corporate social responsibility (CSR) for over two decades, Mr Kwek Leng Joo has raised CDL's standing as a green building champion and forerunner in corporate social responsibility.

"Mr Kwek's leadership, invaluable contribution and presence will be greatly missed by the board, management and employees of the CDL Group," CDL said in a statement on Monday.

"The Board sincerely appreciates Mr Kwek's dedicated service over the years, and together with CDL's management and employees, extend their deepest sympathies to his family."

Just last month, Mr Kwek was among four winners to be conferred the President's Award for the Environment (PAE) 2015, Singapore's highest environmental accolade that recognises individuals and institutions for their outstanding contributions in environmental and water resource sustainability in Singapore.

In his illustrious career, Mr Kwek contributed actively to the business and civic communities through many public appointments. He co-chaired the International Panel of Experts on Construction Productivity & Prefabrication Technology comprising leading experts in the field of design and construction management and productive methods.

Mr Kwek also served as president of the Singapore Chinese Chamber of Commerce & Industry (SCCCI) from 1993-1997 and 2001-2005 and is currently an honorary president of SCCCI. He is also president of Singapore Compact for CSR, which is the national CSR society and local network for the United Nations (UN) Global Compact.

A philanthropist, volunteer and an avid photographer, Mr Kwek has raised over S$3 million from the sale of his photo works and art books for various environmental and charitable causes. In September this year, Mr Kwek was listed on the 9th Forbes Asia's Heroes of Philanthropy List.
