Generated Summary
This report investigates the meat and dairy industry’s use of an alternative accounting method, GWP* (Global Warming Potential Star), to potentially mask the impact of their emissions. It explores how this method could allow companies to report lower greenhouse gas emissions without reducing livestock numbers. The study analyzes the implications of GWP* compared to the standard GWP100 metric, particularly focusing on methane emissions from livestock and its impact on global warming. The research involved examining internal documents, reports, and industry practices to understand the adoption and potential effects of GWP* on emission reduction targets and the overall perception of the industry’s environmental impact. The report emphasizes the role of the Paris Agreement and how the use of GWP* could affect countries’ abilities to meet their climate goals.
Key Findings & Statistics
- Methane is a significant contributor to global warming, with 32 percent coming from livestock, primarily cattle burps and manure management.
- Ireland is proud of its dairy exports, which hit a record value of €6.8 billion in 2022.
- Some Irish modeling scenarios suggest cattle numbers would have to fall “from 7.2m [million beef and dairy] animals to approximately 4m to get close to this [51 percent] level of reduction.”
- Ireland’s 1.6 million dairy herd.
- A 51% reduction target by 2030 as a result of methane emissions from the agriculture sector.
- For Tyson, an emissions reduction plan of 30 percent by 2030 using GWP* accounting means that, come 2030, the company would be removing almost 83 million metric tons from the atmosphere, according to Urbancic.
- The same calculation using GWP100 for that time period, suggests the company would actually be releasing – putting almost 60 million metric tons of pollution out into the atmosphere.
- For New Zealand, where half of the country’s emissions come from agriculture, a 10 percent emissions reduction target using GWP* could render the entire country methane negative by 2038.
- Yet using GWP100, the report says the same scenario would put emissions at 30 million metric tons of methane released into the atmosphere each year up to 2050.
Other Important Findings
- GWP* accounting allows companies reliant on large-scale, factory farming to present even small methane reductions as “pulling carbon out of the atmosphere.”
- GWP* metric was originally developed in 2018, by a group of researchers from the Oxford Martin School who argued that more commonly used GWPs, like GWP100, do not account for the way different greenhouse gasses have different atmospheric lifetimes and radiative impacts.
- GWP* essentially allows “the biggest producer countries and companies to avoid reducing the number of livestock and transforming food production systems.”
- The key difference between GWP* and GWP100 is that instead of measuring a conversion of methane into CO2 over a 100 year-period, GWP* allows “the scientists and industry groups promoting GWP* [to] assume that the baseline emissions would be set in the recent past, so the change in methane emissions would be compared to a much higher baseline.”
- GWP* “normalizes existing emissions and disproportionately rewards even small methane reductions.”
- Internal documents show the adoption of GWP* is linked to fears the country may, “[fail] to achieve an ambitious 51% reduction target” by 2030 as a result of methane emissions from the agriculture sector.
- The topic of methane and emission reduction is a sensitive one given that Ireland is proud of its dairy exports, which hit a record value of €6.8 billion in 2022.
- The freedom of information request also revealed internal briefing documents for Ireland’s international trade representatives, which stated that the agriculture ministry “would like to see progress in the area of metrics (GWP* v GWP100) which would better reflect the global warming impact of methane from livestock production systems.”
- Tyson has told Sentient Media that it uses GWP100 and “does not consider GWP* as an option.”
- The National Cattlemen’s Beef Association, a trade group representing cattle producers and meat companies such as Tyson and McDonalds, has used GWP* “to argue that American cattle ‘may not be contributing much at all to global warming’ and says it is working internationally via the International Beef Alliance ‘to ensure that everybody is working towards adoption of GWP*.”
- New Zealand currently reports on all its greenhouse gas emissions, including biogenic methane, using the GWP100 metric.
Limitations Noted in the Document
- The report focuses on the potential impact of GWP* and does not provide a direct assessment of the actual emissions of companies.
- The study relies on the examination of internal documents, which may be subject to biases or incomplete information.
- The report’s conclusions are based on the assumption that the meat and dairy industries will widely adopt GWP*.
- The analysis of the different metrics is not exhaustive.
- The report does not include direct measurements of methane emissions.
Conclusion
The report highlights the potential for the meat and dairy industries to manipulate their reported environmental impact through the use of GWP*. The findings suggest that GWP* could enable companies to present a misleadingly positive picture of their emissions, potentially hindering efforts to reduce greenhouse gas emissions and meet climate targets. The report emphasizes the importance of using the GWP100 metric for accurate reporting and the need for transparency in the industry’s environmental accounting practices. The study’s analysis reveals the complex interplay between industry practices, governmental policies, and climate goals, and calls for greater scrutiny of the environmental impact of meat and dairy production. The report concludes by highlighting the need for transparent and accurate measurement of greenhouse gas emissions to ensure meaningful progress in reducing the environmental impact of the agricultural sector. As Nusa Urbancic points out, GWP* essentially allows “the biggest producer countries and companies to avoid reducing the number of livestock and transforming food production systems.” The potential for misleading results necessitates a critical examination of the metrics used to assess the industry’s environmental footprint. The report’s findings have significant implications for climate policy, consumer awareness, and the broader effort to combat climate change.
