The climate impact of wild pigs around the world is equivalent to the greenhouse gas emissions of 1.1m cars annually, according to new research.

Modelling by an international team of researchers estimates that feral pigs release 4.9m metric tonnes of carbon dioxide each year globally by uprooting soil.

Researcher Dr Christopher O’Bryan of the University of Queensland said feral pigs were one of the most widespread vertebrate invasive species on the planet.
