Apple has issued a $1 billion (£0.8bn) green bond to finance clean energy and environmental projects.
It comes a year after its first green bond of $1.5 billion (£1.2bn) – the largest from a US corporation – and follows Donald Trump’s decision to pull out of the Paris climate deal.
The technology giant said its second green bond is meant to show businesses are still committed to the green goals set out in 2015.
Hawaii recently became the first US state to formally adopt pledges backing the Paris climate agreement.
Apple Chief Executive Tim Cook was said to be one of several CEOs who directly appealed to Trump to keep the US in the pact.
Lisa Jackson, Apple’s Vice President of Environment, Policy and Social Initiatives said: “Leadership from the business community is essential to address the threat of climate change and protect our shared planet.”
