On July 14, 2015, Iran and the six world powers reached a landmark nuclear agreement known as the Joint Comprehensive Plan of Action (JCPOA).
On January 16, 2016, anti-Iran sanctions were lifted as the International Atomic Energy Agency (IAEA) verified Iran's nuclear program and 'Implementation Day' of the JCPOA started.
Coincident with Iran Enviro Fair, the 8th International Renewable Energy, Lighting and Energy Saving Exhibition is also to be held on that day.
