Methane campaign is 100% politics
OPINION: We are endlessly told that livestock are responsible for half of New Zealand's total emissions.
The headline, created to excite interest, was "Scientists accuse New Zealand and Ireland of trying to cover up livestock emissions".
The article was referring to an open letter to Prime Minister Christopher Luxon. The scientists, some of whom are from New Zealand, explained the issues clearly. It was the journalists or sub-editors who appeared to be the source of the emotive words 'accuse', 'cover up' and also the term 'accounting trick'.
The scientists did state: "Adoptinf targets consistent with 'no additional warming' ignores the scientific advice. It implies that current methane emissions levels are acceptable. They are not."
The scientists also explained why, citing both the Paris Agreement of 2015 and the Methane Pledge of 2024.
In the confusion of different models, metrics, targets and politics, the economics are being lost. The overall goal seems to be suffering similarly.
The Government wants the country to be economically viable, and the primary sector is the foundation.
The various statements made about the primary sector during the lead up to and at the Fieldays at Mystery Creek made that clear.
New Zealand farmers need and want to be economically viable. That means being efficient.
Efficiency gains, made in the absence of producer support (subsidies) are what have put New Zealand in pole position for producing the most high-quality protein (meat and milk) for fewest greenhouse gases (GHG).
Speaking at the DairyNZ Farmers' Forum at the end of May, Vangelis Vitalis, Deputy Secretary, Trade and Economics for the Ministry of Foreign Affairs and Trade, explained that over 85% of the discussion on trade agreements have climate at their heart.
What is New Zealand doing to reduce its impact and keep playing on the global stage?
The answer lies in the Paris Agreement: "in a manner that does not threaten food production".
Whilst we debate about the metrics and targets and whether a different model should be used to calculate, effect, what are we doing to calculate our contribution of high-quality protein to the world?
Can we calculate how many of the essential amino acids that make up accessible protein are supplied through meat and milk for how many GHG?
StatsNZ data released at the beginning of May showed sheep numbers had decreased 3% in the year to June 30th 2024 to 23.6 million. Numbers of beef cattle had increased by 3% to 3.7 million, and deer numbers were down 4% to 709,000. Total dairy cattle numbers had decreased by 1% to 5.8 million, but production of milksolids had increased slightly (less than 0.5% from DCANZ data, reflecting a similar increase in the size of the milking herd (DairyNZ and LIC data)).
What is the effect overall on food being supplied to the global market?
The open letter from scientists to the Prime Minister reminded us that developed countries have a commitment under Article 4 of the Paris Agreement: their responsibility is that Nationally Determined Contributions (to GHG reductions) reflect their highest possible ambition.
The reduction pledge recognises the conclusion of the Intergovernmental Panel on Climate Change (IPCC) Sixth Amendment report "that swift reductions in methane pollution are a key component of actions to limit warming in line with the long-term temperature goal of the Paris Agreement..."
This statement acknowledges that methane is a short-lived gas, and that bringing emissions down will have a relatively rapid effect.
Bearing in mind the Paris Agreement phrase "Without threatening food production" gives us a path forward for staying with the developed countries (doing everything we can) while enabling farmers to continue supporting the economy (increasing efficiencies in producing high-quality protein).
And keeping the social licence to operate.
All farmers know that the best way of moving animals calmly is to open the gate, step back, and let the leaders think that going through is their own idea. This technique has been known to work on partners and children. Perhaps it is time to consider the benefits of this tactic when we are working with politics.
