Meat and Dairy Fail Climate Neutrality Goals.

Spread the love

The meat and dairy industry’s efforts to achieve ‘climate neutrality’ can be likened to reducing the amount of gasoline poured on an inflamed house while continuing to fuel the blaze. Their assertions of becoming ‘fire neutral’ are misleading, as the industry remains a significant contributor to climate change, challenging the meat dairy climate balance.

The impact of meat and dairy on the planet - Dr Joseph Poore

Imagine a house is on fire, and someone is actively pouring gas on the fire. They then pour a little less gas and want credit for doing so, despite still feeding the fire. Perhaps they claim they are now “fire neutral.” We’d rightly be very skeptical of such claims. Yet that is more or less what some influential supporters of the livestock industry have done.

Misleading Claims of Climate Neutrality

In recent years, there have been eye-catching studies published in peer-reviewed livestock science journals claiming that the meat and dairy industries are or can easily be “climate neutral.” These claims have gained significant attention and have been adopted by industry bodies and widely publicized. However, it is important to approach these claims with skepticism and a critical eye.

The Role of Methane Emissions

Methane is a potent greenhouse gas that contributes to global warming. It accounts for 0.5°C of global warming so far, and livestock production is responsible for about one-third of human-caused emissions. Methane is produced during the digestion processes in cattle, sheep, and other ruminants, and is emitted when they belch.

A Distorted Understanding of Science

In a recent paper published in the journal Environmental Research Letters, my co-author and I argue that the claims of climate neutrality in the meat and dairy industry represent a distorted understanding of the science. These claims can be used for greenwashing and undermine confidence in climate science.

The Problem with Definitions

The term “climate neutral” was originally used to refer to net-zero emissions of greenhouse gases. However, some of the reports we examined have subtly shifted the meaning of the term by using a new metric called GWP* (Global Warming Potential Star). This metric represents the warming impact of greenhouse gases over time. By using GWP*, these reports redefine climate neutrality as net-zero additional warming, rather than net-zero emissions.

The “Cooling Effect” and Its Limitations

These studies claim that a livestock sector with high but declining methane emissions can be considered climate neutral because it adds less additional methane to the atmosphere each year. They refer to this as a “cooling effect,” which is misleading since it only results in slightly less warming, not actual cooling. Furthermore, these studies fail to acknowledge that the “cooling” effect of methane reductions is temporary and that the level of emissions will still contribute to significant warming.

The Risks of Greenwashing

While GWP* has its merits when applied at the global level, using it to assess a specific sector like livestock can lead to greenwashing. Greenwashing is the practice of making misleading or unsubstantiated claims about the environmental benefits of a product, service, or industry. By presenting high-emitting industries as climate neutral, these claims can confuse businesses, consumers, and policymakers and undermine efforts to reduce emissions across all sectors.

The Urgency of Reducing Emissions

These recent claims of climate neutrality in the meat and dairy industry distract us from the urgent challenge of reducing emissions of all greenhouse gases from all sectors, including agriculture. It is important to focus on comprehensive strategies to address climate change rather than relying on questionable claims of neutrality.

In conclusion, it is crucial to approach claims of climate neutrality in the meat and dairy industry with skepticism. The use of metrics like GWP* can distort understanding and lead to greenwashing. Instead, we should prioritize efforts to reduce emissions across all sectors and work towards a more sustainable future.

FAQ’s

1. What are the claims of climate neutrality in the meat and dairy industry?

Some studies claim that the meat and dairy industries can be “climate neutral,” meaning they have net-zero emissions of greenhouse gases. This claim has gained attention and been widely publicized.

2. How do methane emissions contribute to global warming?

Methane is a potent greenhouse gas that contributes to global warming. Livestock production is responsible for about one-third of human-caused methane emissions. Methane is emitted during the digestion processes in cattle, sheep, and other ruminants.

3. What is the problem with the definition of “climate neutral”?

The definition of “climate neutral” has been subtly shifted by some reports, using a new metric called GWP*. This metric redefines climate neutrality as net-zero additional warming, rather than net-zero emissions of greenhouse gases.

4. What is the “cooling effect” mentioned in the studies?

The studies claim that a livestock sector with high but declining methane emissions can be considered climate neutral because it adds less additional methane to the atmosphere each year. However, this “cooling effect” only results in slightly less warming, not actual cooling, and the level of emissions still contributes to significant warming.

5. What is the risk of greenwashing in the meat and dairy industry?

Using metrics like GWP* to assess the livestock sector can lead to greenwashing, which is the practice of making misleading or unsubstantiated claims about environmental benefits. By presenting high-emitting industries as climate neutral, these claims can confuse businesses, consumers, and policymakers and undermine efforts to reduce emissions.
