MRV of Soil Organic Carbon: where we are and what is missing?
Martial Bernoux
Climate and Environment division

A MRV system refers to any process or system which aims to assess and monitor the
impacts of mitigation measures and/or the support provided (measuring) and to
document this information in a transparent way (reporting), so that it can be examined
for accuracy (verification).
M = Measurement (or estimation), sometime “Measuring” or “Monitoring”
R = Reporting (at different level: national, international,…)
V = Verification (sometime Verifying) includes Quality Control (QC) and Quality Assurance (QA)
What is MRV?
MRV of national inventory (e.g. sources and sinks of GHG)
MRV of policy (e.g. NAMA, mitigation measures)
MRV of project (CDM, …)
MRV of implementation (e.g. financial flow)
MRV of a REDD-plus activities
… MRV of soil carbon …
or more broadly MRV of soil C sequestration and GHG fluxes related to soil management
MRV of actions in the Paris Agreement context and ETF

Criteria to respect
Consistency: Same methodology apply along years and uses consistent datasets
Completeness: All GHG and all sinks and sources category are reported
Accuracy: Not biased and reduced uncertainty as far as possible
Transparency: Assumptions, hypothesis and methodologies used are explained
and documented
Comparability: Comparable methods should be used by all stakeholders of
the MRV system
Guidance from the Task Force on National GHG Inventories (TFI) which main objective is to develop and refine an
internationally-agreed methodology and software for the calculation and reporting of national GHG emissions and removal
The Guidelines evolved concomitantly with UNFCCC/KP and PA needs and decisions

Where are we?
Soils are in Volume 4 (AFOLU)
https://www.ipcc-nggip.iges.or.jp/public/2019rf/vol4.html
• Updated References SOC stocks for mineral soils
• New Tier 2 method (based on simple soil C model)
• Examples of Tier 3 approaches (Australia, Finland, Japan, USA)
• Updated and new scaling factors: default stock change factors for land use (FLU), input (FI) and management (FMG)
The Tier 2 steady-state method, based on a soil
C model, features intermediate complexity
between Tier 1 and Tier 3 methods

Then what is missing? A clear and unambiguous “signal” from policy makers
A unique opportunity: Koronivia Joint Work on Agriculture
(a) Modalities for implementation of the outcomes of the five in-
session workshops on issues related to agriculture and other
future topics that may arise from this work;
(b) Methods and approaches for assessing adaptation, adaptation
co-benefits and resilience;
(c) Improved soil carbon, soil health and soil fertility under
grassland and cropland as well as integrated systems,
including water management;
(d) Improved nutrient use and manure management towards
sustainable and resilient agricultural systems;
(e) Improved livestock management systems;
(f) Socioeconomic and food security dimensions of climate
change in the agricultural sector.
Under the UNFCCC not the Paris Agreement!

The narrative is evolving from
“Soil Carbon sequestration“ to “heathy soil”
We have never been so close to have a conclusion/decision
at next COP that would be a game-changer
A clear signal supporting more investments for healthy soils
Research, modalities, pilot phases, scaling up.…
Soils fully considered in most NDC

Soils in NDCs Moving from the current situation to using the full potential offered by “soils”
 Soil MRV systems should be connected with other AFOLU subsectors/activities (nutrient
and manure management, livestock management, …) and all topics of the KJWA
decisions (adaptation, food security, socio-economic dimensions)
 Soil MRV systems should be part/compatible of a broader national system serving
different reporting needs:
 UNFCCC: Modalities, procedures and guidelines (MPGs) for the enhance
transparency framework (ETF) for action and support, this means also
(BTR, NC, BUR
 Outside the UNFCCC: UNCCD, CBD, SDGs, etc…)
 National capacities (including research) should be developed / strengthened
 Develop robust institutional arrangement for MRV
Challenges (old/new) are still in front of us
