Cats and Dogs and the Planet

 Cats and dogs come with a steep carbon pawprint. This is mainly because of their diet, which includes a lot of meat and animal products.

1. The meat consumption of cats and dogs in the US produces around 64 million tonnes of CO2 per year, the equivalent of a year’s worth of driving from 13 million cars, according to a 2017 study published in the journal PLOS One.

   The study found that cats and dogs are responsible for 25 to 30 per cent of the environmental impact of meat consumption in the US. A country made up of just cats and dogs would rank fifth in the world for meat consumption, after Russia, Brazil, the United States and China, the analysis concluded.

2. “Pets have many benefits, but also a huge environmental impact,” said Gregory Okin, author of the study and a geography professor at the University of California, Los Angeles. 

3. Dry pet food production emits 106 million tonnes of carbon dioxide each year, more than countries such as Mozambique and the Philippines, according to a 2020 study by researchers at the University of Edinburgh. 

4. A country producing the same amount of carbon emissions would be the world’s sixtieth highest emitter, the researchers said. Dry food production for cats and dogs uses around 49 million hectares of agricultural land, roughly twice the size of the UK, annually, the study found.

5. 1. “Even accounting for the use of by-products in pet foods, the feeding of companion animals plays a role in environmental change. This is a topic that has been previously overlooked, but we have shown that pets and how they are fed should be considered alongside other actions to reduce climate change and biodiversity loss,” said Peter Alexander,  a senior researcher in food security at the University of Edinburgh.

6. There are already sustainable plant-based products available made from chickpeas, lentils and soybeans.

   According to the Pet Food Manufacturers’ Association, insect-based pet food offers a nutritious, sustainable alternative to food made from animal products. Insects are rich sources of protein and often contain high fats, minerals and amino acids. Insect farming uses a fraction of the land, energy and water required for traditional agriculture, and has a significantly lower carbon footprint. While cows and sheep need huge swathes of pasture to graze on, insects can be reared easily in small spaces. Crickets produce up to 80 per cent less methane than cows, according to a study by researchers from the University of Wageningen in the Netherlands.
