In 2001 a number of national employers’ associations of the chemical industry decided to engage in social affairs at European level. This set-forth the foundation of the European Chemical Employers Group (ECEG) by 11 founding national employers' associations in January 2002.  Currently, ECEG represents 18 national members, which are related to up- and downstream industries.

In 2004 on behalf of the European Chemical Industry ECEG entered into a formalised Social Dialogue in the form of a Sectoral Social Dialogue Committee (SSDC) together with its social partner, the then European Mine, Chemical and Energy Workers' Federation (EMCEF).  The EMCEF dissolved and merged into industriAll Europe Trade Union in May 2012.

In December 2009 the General Assembly of ECEG decided to register as an international non-profit association under Belgian law (“aisbl”). This process was finalised in 2011.

In 2012 ECEG celebrated its 10th anniversary.
