Report for EEA assesses feasibility and impacts of resource taxation for iron/steel, copper and phosphorus
Resource (or raw material) taxation can be applied at different levels: extraction (mining), first industrial use (e.g. for P, fertiliser production) or final consumption (e.g. for P, fertiliser use). In all cases, there are risks for any industry or use which is subject to international competition, because producers or users (mines, food production) outside Europe would not be subject to the tax. This can be neutralised through “Border Tax Adjustment” (BTA).
Avoiding penalising European industry or farmers
Although BTA taxation might be relatively feasible for e.g. imported fertilisers and phosphorus containing industrial substrates (phosphate rock, phosphoric acid), because of the relatively small number of players and the homogeneous nature of the products concerned, it would be much more complex for imported food and animal feeds (difficulty of defining phosphorus content, large number and wide range of importing companies and operators).
The report notes the challenge that “the agricultural sector faces strong international competition, that it is seen as a relevant economic sector, that it receives strong political support and many subsidies in most countries, and that it has a very strong lobby”.
Justification and advantages
The report identifies the following reasons for need for action on phosphorus:
- Non-substitutable in its main use, agriculture
- Considerable environmental impact
- Geopolitical issues related to reserve distribution in different countries in the world
- Tendency to mine lower grade rock
- Impurities in phosphate rock, e.g. cadmium, uranium
- EU is 92% dependent on imported phosphorus
It is noted that overall use efficiency is low (only around 10% of mined P is effectively used) and that use per hectare is highly variable between different European countries (from 3 to 13 kgP/ha/year).
A possible taxation scheme should therefore have as objectives
- To secure long-term availability and reduce import dependency
- To reduce phosphorus losses into surface water
- To close the phosphorus cycle as far as possible, reducing inputs and outputs and developing recycling
In particular, the scheme should provide incentives to recycling, to reduction of losses from arable and animal farms, and to reduce the use of phosphate rock with high heavy metal contents.
Experience with phosphorus taxes
Experience from several EU states is summarised:
Overall, analysis of these examples suggests that the taxes had little effect unless the level was quite high. However, there was a long-term effect of better information and awareness of farmers. The Netherlands MINAS tax on farm nutrient surpluses was considered effective, but had difficulties of administrative complexity, and has been replaced by regulatory policies using the same based (obligation for farm nutrient balances). The Sweden tax scheme is considered effective, probably because the level of taxation is relatively high (3.3€ per g cadmium exceeding 5gCa/tonneP) and because it was accompanied by action programmes to reduce use.
The report notes that these experiences did not include BTA on imported products containing phosphorus, such as food products.
Stimulating innovation and efficiency
The report notes that the prices of raw materials is often relatively low, so that taxation would have to be at a very high level to modify use patterns sufficiently to significantly reduce resource consumption, environmental impact.
Phosphorus in fertiliser, however, offers a specific case, in that it is non-substitutable and essential for agricultural production. An appropriate level of taxation on virgin mineral phosphorus use could thus potentially stimulate both improvements in efficiency of use on farms and innovation and implementation of recycling (better use of or phosphorus recovery and recycling from organic sources such as sewage or manures).
Short-term price elasticity for phosphate fertilisers is cited as maybe -0.1 to -0.25, suggesting that a 10-fold price increase would be needed to reduce use by 50%, assuming that this can be substituted by phosphorus from organic streams (sewage, manure).
A high potential for increasing phosphorus use efficiency is identified throughout the use chain, not just in fertiliser use, but also in food production and dietary choice.
The report notes that a tax on products implying high phosphorus use in their production (e.g. meat) could be more effective that a tax on phosphorus fertilisers, but would pose implementation issues because of difficulties in calculating how much phosphorus is needed to produce one kilogramme of meat. Nonetheless, the current reduced rate of VAT on meat could be questioned.
The report concludes that probably no single tax tool could effectively target all uses of phosphorus and that a phosphorus use tax should be part of a policy mix with other instruments. In particular, the report notes that there are a number of tools in agricultural policy, including bio-fuels policies and agricultural subsidies which could be adjusted to incite phosphorus use efficiency, reduce phosphorus losses, reduce soil erosion, and encourage phosphorus recycling.
