Orange County Convention Center (OCCC) in Orlando, the second largest conference space in the US, will host MPI’s event on 23-26 July.
MPI president Bruce MacMillan said: "We are thrilled to bring WEC 2011 to a city like Orlando with such a rich history in corporate social responsibility."
MPI chose the OCCC partly due to the venue’s corporate social responsibility bid element.
The venue uses solar energy and runs a climate change education centre, as well donating products from conferences to local charities.
OCCC deputy general manager Kathie Canning said: "We are rolling out the green carpet for WEC attendees. Orlando has enjoyed a long-lasting and successful relationship with MPI and it was an easy decision to present our CSR initiatives for meeting planners at WEC."
