The meat and dairy industry’s impact on the climate is often overlooked, despite being a significant contributor to methane emissions. Methane levels have more than doubled in the past two centuries, with 600 million tonnes released annually, predominantly from human activity. This potent greenhouse gas is 80 times more effective at trapping heat than carbon dioxide over a 20-year period, making it a major driver of global heating.
Animal agriculture is a major source of methane emissions, responsible for 32% of human-caused methane emissions. The digestion process of livestock produces methane, as does the management of their manure. With 83 billion land animals slaughtered each year for meat production, the industry continues to drive these harmful emissions.
Changing Markets Foundation and Mighty Earth are calling on food retailers to take action by publicly reporting their emissions, setting science-based climate targets, and reducing methane emissions by at least 30% by 2030. Leading food retailers have the power to influence supply chains and consumer choices, making them key players in transitioning to a more sustainable food system.
Excessive meat consumption not only harms the environment but also poses risks to human health. Red and processed meat intake has been linked to various health issues, including heart disease, diabetes, and cancer. The World Health Organization warns of the dangers of processed meat in particular, citing its link to colorectal cancer.
In addition to the environmental and health risks, the meat industry’s use of antibiotics in livestock farming has contributed to the rise of antibiotic-resistant bacteria, posing a threat to public health. Antimicrobial resistance can lead to higher mortality rates, prolonged illness, and strain on healthcare systems worldwide.
Food retailers must develop climate plans to reduce methane emissions from meat and dairy sources, promote transparency in reporting, and set targets for methane reductions. Consumer awareness of the environmental and health impacts of food choices is growing, putting pressure on retailers to take action.
By addressing methane emissions and promoting sustainability, food retailers can not only lead the way in the fight against climate change but also rebuild consumer trust and establish themselves as leaders in the industry. Failing to address methane emissions now risks further damage to the planet, jeopardizing our future and the global economy.
As the urgency of the climate crisis escalates, it is essential for food retailers to step up and prioritize sustainability. By embracing this challenge, they can make a significant impact on reducing methane emissions and mitigating the effects of climate change.
