The other agencies that pitched against TBWA for lead agency status will gain a place on the Carbon Trust’s roster. These include McCann Erickson, JWT and a partnership between Beta and WDMP.
WCRS, which previously held lead agency status on the account, declined to repitch for the business when the Carbon Trust called a statutory review in February.
Universal McCann will continue to handle media buying on the account.
A Carbon Trust spokesman said: "No contract has been awarded yet."
