The charity has begun the process of approaching agencies with a request for proposal. Proposals need to be submitted by 15 June as Unicef gears up for the festive fundraising activity.
On an international basis the charity has used TBWA Chiat Day LA and Droga 5 but has approached agencies beyond those it currently works with as it looks to drive awareness and revenues.
The pre-Christmas activity will follow a social media campaign in March that saw Unicef partner with environmental group Do The Green Thing to raise awareness of the effects that climate change has on children in developing countries.
A 90-second online film, voiced by UK newsreader Jon Snow, showed how a young boy would need to adapt in order to cope with drought and flooding bought on by climate change. The activity ran across Spotify, Facebook and Twitter.
In partnership with Lowe Indonesia, Unicef has been recognised by Adfest and One Show among others this year for its 'Screen off' campaign, encouraging families to switch off the TV and spend more together.
Unicef was unavailable for comment.
