Apple this week acknowledged it is still battling poor working conditions and environmental violations with some of its overseas supplier factories, but highlighted programs to solve ongoing issues, according to a company audit.

Apple’s annual Supplier Responsibility Report addressed conditions at 756 sites in 30 countries last year and scored facilities based on its Code of Conduct.

One bright spot: fewer children are working on the much-prized Apple devices.
