"As a bank and insurance company,understanding weather change and climate risk and how this impacts our customers and our business makes not only good environmental sense but helps us protect and enhance shareholder value and makes good business sense,"Ms McLoughlin told Suncorp's AGM in Brisbane.
Many thousands of protesters joined rallies around the country last week demanding more government action on climate change.
Suncorp faced a number of questions over its green credentials and climate change policies at the annual general meeting including from environmental lobby group,Market Forces,which urged greater disclosure of its targets to cut ties with fossil fuel companies.

"If Suncorp wants to claim that its business is in line with keeping global warming below 1.5 degrees and the Paris Agreement ... then it can't be supporting the expansion of the oil and gas industries,"Market Forces campaigner Pablo Brait said.
Ms McLoughlin said Suncorp's business policies were in line with the transition that was taking place in the broader community in regards to moving away from reliance on fossil fuels.
She said the company's exposure to fossil fuels made up less than 0.5 per cent of the business.
