Peru adopted new and more flexible air quality standards on Wednesday after the old standards were criticised by mining companies and President Pedro Pablo Kuczynski.

A decree published by the environment ministry raised the maximum amount of sulphur dioxide, a byproduct of smelting copper and other base metals, that can be emitted to 250 micrograms per cubic metre per 24 hours, from the 20 micrograms per cubic metre previously.
