"Exxon Mobil Corp, the world's largest publicly traded oil company, has agreed to disclose more information about the environmental risks of hydraulic fracturing, the process known as fracking.

In an agreement with New York City's pension funds, which control Exxon shares worth roughly $1.02 billion, the company would report on risks surrounding disposal of fracking waste water, air pollution, methane emissions from oil and natural gas wells, and other issues.

Exxon plans to compile the information and publish it as a report on its website by September."
