2030 target creating uncertainty around the future of fertilizer use

Opinion

The federal authorities has its eye on lowering nitrous oxide emissions from fertilizer, however it’s not clear the way it intends to succeed in its target, and whether or not the target is achievable with out having a detrimental impression on crop yields.

Final December, whereas saying the federal carbon tax can be growing to $170/tonne of CO2 equal, the Liberal authorities additionally unveiled a 30 per cent discount target for emissions from artificial nitrogen fertilizer by 2030, in comparison with 2020 as a benchmark yr.

The federal government says the discount is critical to fulfill Canada’s 2030 greenhouse gasoline emissions discount target and net-zero by 2050.

Agriculture and Agri-Meals Canada (AAFC) held casual conferences concerning the target with farm and business teams this previous spring. Extra formal consultations on how N fertilizer emissions may very well be decreased by 30 per cent have been deliberate for early this fall, however it’s seemingly they are going to now be delayed by the impending federal election marketing campaign.

Agriculture Minister Marie-Claude Bibeau’s workplace has repeatedly referred to the target as “voluntary” and “aspirational,” nonetheless there’s undoubtedly a perception amongst business stakeholders that it might not stay voluntary if push involves shove with assembly the 30 per cent purpose, which the authorities is relying on to scale back emissions by an estimated 4 megatonnes CO2 equal.

The large query: might the authorities in the end prohibit or cap the quantity of fertilizer farmers use to fulfill this 30 per cent target?

It will depend on whether or not emissions may be decreased by 30 per cent utilizing practices that decrease emissions per unit of fertilizer utilized, comparable to these underneath the 4R nutrient stewardship framework. Simply as essential, it additionally will depend on how emissions — and reductions in emissions — are measured.

In an electronic mail to RealAgriculture, a spokesperson for AAFC emphasizes “the 30 per cent reduction target is not aimed at reducing fertilizer use, but rather at associated nitrous oxide emissions, including direct emissions following fertilizer application, indirect emissions from nitrogen leached from fields, and indirect emissions from ammonia nitrogen volatilization.”

“All practices that could contribute to a reduction in nitrous oxide emissions associated with fertilizer use will be considered, including those associated with the 4Rs,” continues the AAFC official.

If 4R practices are acknowledged, there may be some analysis, together with work led by Mario Tenuta at the College of Manitoba, exhibiting enhanced effectivity fertilizers might probably cut back emissions inside vary of the 30 per cent target. Sorted then, proper?

Not so quick.

As a result of the AAFC spokesperson clearly say modifications in fertilizer emissions “will be measured in line with the methodologies used for reporting nitrous oxide emissions from the agriculture sector in the National Inventory Report (NIR) developed by Environment and Climate Change Canada.”

Even when 4R practices are acknowledged, the authorities’s timeline for implementing, measuring, and accounting for them can also be a difficulty, as from a farmer’s perspective, there are solely eight rising seasons between now and 2030.

This assertion appears to contradict the promise to acknowledge practices that cut back emissions depth, as the NIR hasn’t accounted for 4R practices in the previous.

The NIR follows the UN Intergovernmental Panel on Local weather Change’s requirements for estimating and reporting emissions, and the Canadian authorities is dedicated to utilizing the worldwide protocol, which implies it’s not clear how farm-level enhancements in lowering fertilizer emissions would even be captured in the authorities’s official greenhouse gasoline math.

Even when 4R practices are acknowledged, the authorities’s timeline for implementing, measuring, and accounting for them can also be a difficulty, as from a farmer’s perspective, there are solely eight rising seasons between now and 2030.

Add all of it up, and you may’t assist however surprise about the probability of restrictions on fertilizer use — a cap on emissions from nitrogen fertilizer — serving as the authorities’s mechanism for reaching the 30 per cent discount.

Fertilizer Canada, the Western Canadian Wheat Growers Affiliation, Grain Growers of Canada, and others are warning the authorities that restrictions on general fertilizer use would have a direct unfavourable impression on crop yields, farm incomes, and Canada’s general agricultural output. It’s attainable general emissions might even improve, as extra acres and different inputs, comparable to gas, would seemingly be required to supply the similar quantity of meals.

A mandated discount in fertilizer use would additionally contradict the Liberal authorities’s personal acknowledged targets for enhancing agricultural output in the often-quoted Barton Report and the lately handed Liberal coverage movement to advertise Canada as “an agricultural superpower.”

“Let me be clear: reducing N2O emissions by 30 per cent is extremely ambitious and perhaps even unachievable without compromising crop yields and thereby threatening global food security and our position as a global leader in agriculture,” famous Candace Laing, vice chairman of sustainability and stakeholder relations for fertilizer producer and retailer Nutrien, talking to the Home of Commons agriculture committee in Might.

It seems AAFC is conscious of the issues about how emissions from fertilizer will probably be measured. The contributors on this spring’s casual consultations obtained an electronic mail final month indicating future discussions might give attention to the problem of precisely measuring fertilizer emissions, in addition to methods to correctly measure and talk the impression of farm-level practices.

AAFC additionally says it’s in the course of of summarizing the suggestions it has obtained up to now to function a information for the formal consultations that have been to start in early fall.

In Europe, the EU has mandated a 20 per cent discount in fertilizer use, together with manure, by 2030.

Whether or not Canada’s fertilizer coverage will observe what’s taking place in Europe continues to be to be decided at this level, however the dialog, which might have a big impact on Canadian crop manufacturing, has began and can seemingly intensify in the coming months.
