Each year the RELX Environmental Challenge is awarded to projects that best demonstrate how they can provide sustainable access to safe water or sanitation. There is a $50,000 prize for the first place entry and a $25,000 prize for the second place entry. The winners also receive free access for one year to ScienceDirect, our Scientific, Technical & Medical business’ database of full text, scientific information. Projects must have clear practical applicability, address identified need and advance related issues such as health, education, or human rights.
