Insulation maker Kingspan Group said today it was raising €750m from a so-called green private placement.
A green placement refers to a type of instrument that is specifically earmarked to raise money for climate and environmental projects.
The company called the issue the largest corporate green private placement globally to date.
It said the weighted average fixed interest coupon is 1.78% a year, with weighted average maturities of 9.7 years.
Geoff Doherty, Kingspan's chief financial officer, said the company was "delighted" to have agreed terms on its first Green Private Placement at a compelling fixed interest rate.
"The pricing is a testament to Kingspan's planet passionate strategy and provides long term capital to further develop the group in the years ahead," Mr Doherty said.
"As well as extending our maturity profile this transaction will leave us with in excess of €2 billion of cash and committed undrawn facilities," he added.
