New Guidance Launched to Help Countries Track Livestock Emissions

By CGIAR Research Program on Climate Change, Agriculture and Food Security CCAFS

92 developing countries included livestock-related emissions as a target for mitigation in their Nationally Determined Contributions (NDCs). One of the biggest challenges to achieving mitigation in the sector is tracking emissions, for which national inventories are a key tool. However, systems for measuring and monitoring changes in livestock greenhouse gas emissions are under-developed in many countries.

Challenges in compiling data about the activities related to livestock management is a primary barrier. Currently, most developing countries use the IPCC Tier 1 approach which only reflects a change in livestock numbers. Tracking reductions achieved through improvements in management and productivity requires a Tier 2 approach, which uses activity data to estimate emission factors. The problem is that Tier 2 approaches require more activity data, and a lack of good quality activity data is often perceived as a barrier to adopting a Tier 2 approach.

A new guidebook, jointly developed by the Global Research Alliance on Agricultural Greenhouse Gases (GRA), CGIAR Research Program on Climate Change, Agriculture and Food Security (CCAFS), the Food and Agriculture Organization of the United Nations (FAO) and UNIQUE forestry and land use GmbH, provides practical methods for countries to compile the activity data used to implement the IPCC Tier 2 methodology. The purpose is to support countries to improve the accuracy of the livestock emission estimates in national GHG inventories, and thus enable countries to better set their NDC mitigation targets, as well as measure and report progress.

The guidebook provides an 8-step framework for countries to compile activity data (see figure 1 below) and it helps answer the following questions:

  • How to define what data is needed?
  • How to collect the data needed, and how to assess data availability and data quality?
  • How to fill data gaps?
  • How to document the inventory and assess inventory quality?
  • How to plan for continuous improvement?

Each section contains:

  1. Practical guidance on the compilation of activity data,
  2. Overview of related IPCC good practices guidance,
  3. Tools for implementing the practical guidance,
  4. Methodological guidance that explains issues affecting decisions about how to compile activity data,
  5. Examples of how to implement the practical guidance, and
  6. Links to additional resources.

The guidebook provides practical methods for assessing data availability and data quality and practical methods for systematizing available data and filling data gaps using methods consistent with the IPCC guidelines. Through worked examples of gap-filling methods, the guidebook shows that an initial Tier 2 inventory can be compiled and used to identify priorities for data collection as part of a continuous improvement process.

The guidance was compiled around the same time as Kenya developed its first Tier 2 inventory for dairy cattle with support from the GRA, and several examples in this guidance are drawn from that experience. The guidebook is already being road-tested in other countries, and the experiences gained will contribute further methods and examples.

This guidebook fills a long-standing gap in learning resources dedicated to improving livestock GHG inventories. It shows that the lack of activity data is often more of a perceived, rather than a real, barrier to adopting a Tier 2 approach. When first adopting a Tier 2 approach for livestock GHG emissions, there are few countries—including developed countries—where all the necessary livestock activity data are readily available and of good quality.

Using the tools and methods explained in this guidebook, countries will be able to compile an initial Tier 2 inventory that is consistent with the IPCC guidelines and prioritize the use of resources for continual improvement over time. This will help countries to comply with the agreements on transparency under the Paris Agreement and will provide a better basis for identifying mitigation options and tracking change in emissions from the livestock sector.

In December 2019, Typhoon Kammuri flooded parts of Legazpi City, one of the biggest natural hazard hotspots in the country. Earlier that year, USAID had helped the local water district develop an emergency preparedness plan for maintaining and restoring water services when disasters strike.
Sustainable transportation is critical for both inclusive economic growth and low-emissions development. A long-term strategy (LTS) is a policy tool that establishes a vision and pathway towards sustainable, low-emissions development to 2050, and helps national planners understand the actions needed to achieve that vision while also supporting national climate commitments. 
In response to growing demand from countries seeking support for increased electric vehicle (EV) deployment to bolster climate change objectives, the USAID-NREL Partnership has developed several different projects aimed at streamlining development of EV charging infrastructure, workforce training, and grid management, which build upon the recently launched global Greening the Grid EV Toolkit.
