Sustainer Members

Members who make a recurring monthly or quarterly gift as part of Earthwatch’s Sustainer program help to save time and resources by eliminating the need for pledge forms and renewal mailings. Sustainers will be given one summary statement of giving at the end of the calendar year in lieu of monthly receipts, and may elect to receive donor newsletters and other publications electronically.

YOUR SUPPORT MATTERS

Earthwatch depends on donations—above and beyond what we raise from volunteers who participate in our expeditions—to deliver our global conservation mission. In fact, volunteer contributions provide only half of the total resources Earthwatch needs to sustain over 20 global field research expeditions, a wide variety of educational programs, corporate sustainability trainings, and more each year.
