NEW YORK (AP) — Exxon Mobil issued a report Tuesday that acknowledges the environmental risks of hydraulic fracturing but also defends the practice as being better for the environment than other types of energy production and generation.

Under pressure from the corporate responsibility group As You Sow, as well as New York City Comptroller Scott Stringer and other shareholders, Exxon agreed earlier this year to reveal more about how it manages the risks involved with the drilling technique, known as fracking.
