Agriculture Methodology

Agriculture Methodology

Agriculture drives our societies and economies, but agricultural practices are also important factors in driving in-country GHG emissions. Climate-conscious agricultural policies represent a large opportunity for countries to reduce their emissions.

The Agriculture Guidance supports the assessment of the GHG impacts of agricultural policies and actions. This guidance fills a gap in currently available guidance, which includes project-level agricultural GHG accounting, but does not include GHG accounting at the agricultural policy level.

The Agriculture Guidance leverages existing methods and tools to provide general principles, concepts and a method for estimating GHG impacts. It includes:

  • Ex-ante assessment of expected future GHG effects
  • Ex-post evaluation of historical GHG effect to ensure intended results have been achieved
  • Links to data, tools, models and methods for quantifying GHG effects

The guidance focuses on agricultural policies and actions that mitigate GHG emissions from enteric fermentation and soil carbon pools.

Chapters 1 & 2
What is the guidance and why should I use it?
Empty div

These chapters provide an introduction to the guidance and an overview of objectives users may have in assessing the GHG impacts of agriculture policies. This section should be read to understand whether to use the guidance and to determine what objectives it will be used for.

Chapters 3 & 4
Overview of the methodology
Empty div

This section provides an overview of the types of agriculture policies, and mitigation practices and technologies, to which this guidance can be applied. It also lays out an overview of the steps involved in assessing the GHG impacts of agriculture policies, and provides guidance on planning the assessment.

Chapter 5
How to describe the policy or action being assessed
Empty div

In this chapter, users will get guidance on the first step of the assessment process, describing the policy that will be assessed. Guidance is also provided on deciding whether to assess an individual policy or a package of related policies and choosing whether to carry out an ex-ante (forward-looking) or ex-post (backward-looking) assessment.

Chapter 6
How to choose which GHG impacts and indicators to assess
Empty div

This chapter provides guidance for identifying the impacts of agriculture policies. The guidance helps users to develop a causal chain by considering how the policy will be implemented, who will be affected by the policy, what the potential intermediate effects of the policy will be, and how these effects cause GHG impacts.

Chapters 7 - 9
How to quantify the GHG impacts
Empty div

The guidance in Chapter 7 can be used for determining the baseline scenario and estimating emissions ex-ante or ex-post. Estimating the baseline emissions is optional as the guidance provides two ways for users to estimate GHG impacts. The activity data approach allows users to estimate the GHG impacts without explicitly determining separate baseline and policy scenarios. Chapter 8 helps users estimate expected future GHG impacts of the policy. Users can estimate impacts based on the implementation potential of the policy using either the emissions approach or the activity data approach. Chapter 9 provides guidance for estimating impacts ex-post. Ex-post assessment involves evaluating performance of the policy based on monitored or observed data collected during the policy implementation period.

Chapters 10 & 11
How to monitor indicators over time and report the results
Empty div

This section is relevant for all users. Chapter 10 identifies data and parameters to monitor over time and provides guidance on how to develop a monitoring plan. Chapter 11 provides a recommended list of information to be reported, which ensures the impact assessment is transparent and gives decision-makers and stakeholders the information they need to properly interpret the results.

Appendix A - C
Additional Guidance
Empty div

These appendices provide additional guidance or information on involving stakeholders in the impact assessment and discount rates. The final section explains how the scope of this guidance was selected.
