Request for Proposals – Borehole Drilling
The World Wide Fund for Nature (WWF) is an independent conservation organization, with over 30 million followers and a global network active in nearly 100 countries. WWF’s mission is to stop the degradation of the Earth’s natural environment and to build a future in which humans live in harmony with nature by conserving the world’s biological diversity, ensuring that the use of renewable natural resources is sustainable, and promoting the reduction of pollution and wasteful consumption.
