Cambridge Global Challenges


The competition is looking for solutions that apply behavior change
insights to inspire and enable people to change the way
they consume – the way they cook, eat, dispose of waste,
purchase goods, travel, and more.

The Solution Search Contest is funded by Conservation International, National Geographic, rare, The Nature Conservancy, UNDP and WWF.


the judges are looking for campaigns and efforts that:

  • Increase plant-rich diets
  • Reduce end-user waste
  • Increase demand for products such as locallygrown staple trees, crops grown through regenerative or conservation agriculture, kelp or certified sustainable wood
  • Increase adoption of clean cookstoves
  • Reduce consumption of energy, water or relevant products, such as paper or cotton
  • And otherwise reduce greenhouse gas emitting behaviours amongst individuals, households and communities

We have categorized behavior adoption strategies into three core approaches:

  • Emotional appeals: Unleash the power of emotions to drive change
  • Social incentives: Change social norms to influence adoption
  • Choice architecture: Utilize context and timing to support change

The most urgent environmental challenges of our time share one thing in common – to solve them, people have to start behaving differently.

Award size

Two grand prizes of $25,000 each, awarded to the Judges’ Choice and People’s Choice.
