The HVE Standard: Four Grids, Ten Points, and Blocking Criteria

High Environmental Value has a reputation for being a complicated standard. It is above all one of an unusual logic: four independent grids, an identical threshold on each, no compensation possible between them. Once this principle is understood, preparation becomes methodical.

A single route since 2023

Until 2022, level 3 of the environmental certification of farms was accessible by two routes.

Route A assessed performance theme by theme, using composite indicators.

Route B was more global: it rested on the weight of inputs in turnover and on the share of agro-ecological infrastructure in the utilised agricultural area.

The revised standard, applicable to certificates issued since 1 January 2023, removed route B. There is now only one door to the HVE mention: route A.

This revision did three things at once: raise several performance thresholds, create new point-earning items, and introduce blocking criteria on the biodiversity and crop protection strategy themes. Certification became more selective, which explains part of the movement in certified numbers: after an unprecedented fall between July 2024 and January 2025, the number of certified farms rose again in the first half of 2025. At 1 June 2025, the ministry of agriculture recorded 39,738 HVE-certified farms, of which 32,509 — nearly 82 % — already fell under the revised standard.

The ten-point rule, with no compensation

The principle of route A holds in one sentence: the farm must obtain at least ten points on each of the four grids.

These grids correspond to the four themes of the scheme:

• biodiversity;
• crop protection strategy;
• fertilisation management;
• water resource management.

Each grid aggregates several items, whose scoring is set by regulation. The crucial point is the absence of compensation: totalling twenty points in biodiversity does not buy back eight points in crop protection strategy. Preparation therefore consists in identifying the weakest grid and working on that one, not maximising the total.

A second principle conditions all the calculations: certification covers the whole farm. A wine farm owning a few hectares of cereals must include them in the scope. There is no partial certification of a single line.

What each grid seeks to measure

The detail of the items and the scoring belong to the regulatory text in force, which must be consulted in its applicable version — do not build your strategy on a summary, this one included. The logic of each grid, however, is simple to grasp.

Biodiversity. The grid values the room left for non-productive elements and the diversity of the cropping plan. The share of the utilised agricultural area occupied by agro-ecological infrastructure — hedges, grass strips, copses, ponds, isolated trees — and the diversity of the crops present on the farm play a central role.

Crop protection strategy. The grid draws on the intensity of product use, assessed notably against treatment frequency indices referenced to benchmarks, and on the practices that reduce that use.

Fertilisation management. The balance of nitrogen fertilisation at farm scale and the practices limiting losses structure this grid.

Water resource management. The reasoning behind inputs and the irrigation-steering tools are assessed, with specific treatment for non-irrigated farms.

At its core, this architecture reflects a choice: measure outcomes rather than impose means. That choice has a scientific justification. The review by Kleijn and Sutherland published in 2003 in the Journal of Applied Ecology (“How effective are European agri-environment schemes in conserving and promoting biodiversity?”) had shown, from 62 studies across six European countries, that European agri-environment schemes produced very uneven effects depending on the species group, and highlighted the lack of robust evaluation of these schemes (see the study). It is precisely this criticism — means engaged without measured outcomes — that the indicator logic seeks to correct.

Blocking criteria: to be checked first

A blocking criterion is a requirement whose breach prevents certification, whatever the point total obtained. The revised standard introduced them on the biodiversity and crop protection strategy themes.

The practical consequence is an order of work:

1. check the blocking criteria;
2. identify the weakest grid;
3. work the items of that grid that earn points without upsetting the production system;
4. only then, consolidate the other grids.

Many farms do the reverse and discover at the audit that a comfortable total is not enough.

The data to prepare

The standard is played out on consolidated data. Gather, at whole-farm scale:

• the full cropping plan for the season, all productions;
• the census and measurement of agro-ecological infrastructure, with linear lengths and areas;
• the crop protection records, allowing the treatment indicators to be computed;
• the nitrogen fertilisation plan and balance;
• the irrigation data and the steering tools used.

The advice every auditor repeats: log as you go, in a single tool, with up-to-date areas. A season reconstructed a fortnight before the visit does not survive the verification of supporting documents.

This measurement work has a virtue beyond certification. The study by Lechenet, Dessaint, Py, Makowski and Munier-Jolain published in 2017 in Nature Plants (“Reducing pesticide use while preserving crop productivity and profitability on arable farms”) showed, across a large network of French arable farms, that a reduction in pesticide use was possible without loss of productivity or profitability in a majority of the farms analysed (see the study). But you must measure to know where you stand: the crop protection grid indicators serve that purpose too.

After the calculation, the audit

The points are not self-declared. The initial audit takes place on site, by appointment, with a certification body approved by the ministry of agriculture. The auditor checks the consistency between the declared data and the reality on the ground, verifies the supporting documents and computes the points obtained on each of the four grids.

The certificate is then issued for three years, with a surveillance audit during the cycle and a renewal audit before expiry. The full path, from the first self-assessment to the certificate, is detailed in our guide on how to obtain HVE certification.

Take action

Take your last season’s data and position yourself grid by grid, checking the blocking criteria first: it is the only diagnosis that will tell you whether the audit is a few weeks or a whole season away. For the whole scheme — levels, audit, valorisation, regulatory deadlines — see our guide to HVE certification, and the overview of French certifications to place this scheme among the others.
