Abu Dhabi Islamic Bank has launched a $500 million 5-year green sukuk, an arranging bank document showed on Wednesday.

The Islamic lender set the spread at 115 basis points over the U.S. Treasuries, tightened from 145 BPS over the benchmark earlier in the day after the orders topped $2.20 billion, the document showed.
