According to Patrick Hanson

the CEO of Luxaviation, a Luxembourg-based luxury airline firm, having pets can be just as polluting as travelling by private jet. In defence of his own industry, he declared recently that one of his company’s customers produces around 2.1 tonnes of CO₂ each year, roughly the same emissions as three pet dogs.

The environmental impact of pets is often overlooked. But more than half of people worldwide have a pet in their home, and this number is rising. As of 2023, pet ownership in the US reached 66% of households, an increase from 56% in 1988.

One study, published last year, suggested that feeding a 10kg dog (roughly the size of a standard Dachshund) wet food is associated with the equivalent of 6,541kg of CO₂ emissions each year. This equates to 98% of the total emissions of an average Brazilian citizen.

In 2017, another study produced equally alarming results. This study revealed that the emissions stemming from the production of dry cat and dog food in the US amounted to between 25% and 30% of the emissions associated with animal products consumed by all US citizens.
