May 3, 2021

Arlington, VA – Helping to spotlight local solutions to the world’s most challenging environmental problems, Solution Search today announced the 10 finalists in its Water Pollution & Behavior Change contest. The finalists were chosen from a pool of 100 submissions across 33 countries and will be eligible for two $25,000 grand prizes – the Judges’ Prize, which is determined by a panel of experts and the People’s Choice award, which relies on public voting. The winners will be announced in September 2021 during BE.Hive, a virtual summit and awards presentation event hosted by Rare’s Center for Behavior & the Environment.

Solution Search is a global crowdsourcing contest that surfaces, spotlights and accelerates solutions to environmental challenges that shift individual and community behavior. The approach combines the dynamism of a talent competition, the focus of a mission-driven organization, and the transparency of an online platform to identify how behavioral insights can help solve the world’s most challenging environmental problems.

This year’s contest is supported by Rare, 11th Hour Racing, The Circulate Initiative, the Inter-American Development Bank, Lonely Whale, The Nature Conservancy, and the Ocean Conservancy.

Voting to determine the People’s Choice prize is now open to all, and individuals can vote once per day for as many days as they want during the voting period. The public can vote between May 3 – June 11 by accessing the voting portal here.

In addition to the Grand Prizes, Solution Search: Water Pollution & Behavior Change will award a $10,000 Environmental Justice Prize to the best entry addressing the disproportionate impact of water pollution on communities of color, indigenous groups, and marginalized communities.
