New Delhi: The Art of Living (AOL) Foundation is seeking the National Green Tribunal's permission to submit a bank guarantee rather than paying in cash Rs.4.75 crore as "environmental compensation" for causing damage to the Yamuna floodplain by organising a festival there.

The move by Sri Sri Ravi Shankar's AOL has been described by an environmentalist as "yet another attempt to frustrate the efforts to bring it to account for the damage it caused to the Yamuna floodplains" in Delhi.
