The Intergovernmental Panel on
Climate Change (IPCC) has specified
five indicators of inventory quality:

Valuable Assistance for Preparing
National GHG Inventories

Your GHG inventory team can take advantage of valuable funding, support,
and technical resources to improve the quality of your national inventory.

Transparency: Assumptions and methods are explained clearly so the
inventory can be understood and replicated

• Apply for financial support from the Global Environment Facility for
preparing National Communications and Biennial Update Reports for
submission to the UNFCCC

Accuracy: Estimates reflect actual emissions and removals, with no
systematic overestimation or underestimation

Completeness: All existing, relevant sources, sinks, and gases across a
country's full geographic area are included

• Receive technical assistance on GHG inventory management,
methods, and activity data collection from the U.S. Environmental
Protection Agency and U.S. Agency for Internationa! Development

Consistency: The same methodologies and consistent data sets are
used for the base and all subsequent years in estimating emissions and
removals, so differences in results between years and categories reflect
real differences in emissions

• Participate in training from the UNFCCC Consultative Group of
Experts (CGE)

• Download Agriculture and Land Use (ALU) National GHG Inventory
software for estimating emissions and removals from Agriculture and
from Land Use. Land-Use Change, and Forestry, which is consistent
with Intergovernmental Panel on Climate Change guidelines

Comparability: The methodologies used to develop estimates of
emissions and removals, and how the inventory is reported, allow the
inventory to be compared to those developed by other countries

Activities Supported by National GHG Inventories

Build a Solid Foundation for Low Emission Growth

A greenhouse gas (GHG) inventory can be a valuable tool for developing policies
and programs that address climate change and economic development. GHG
inventories estimate emissions to and removals from the atmosphere over time.
This information can help your country:

•	Understand national GHG emissions, removals, and trends

•	Identify cost-effective policies and programs to reduce emissions

•	Measure success in reducing emissions and enhancing removals

•	Provide input into economic assessments

•	Enhance management of natural resources such as forest stocks
and food production

•	Fulfill United Nations Framework Convention on Climate Change
(UNFCCC) reporting requirements for Biennial Update Reports
and National Communications

But that's just the beginning!

GHG inventories provide an analysis of the economic activities associated with
emissions and removals, such as fossil fuel combustion, cement production,
forest management, crop production, and livestock production. In addition, the
process of collecting and analyzing the data needed to develop an inventory
supports participation in climate change programs, advances economic
development, informs investments, and helps with managing natural resources.

Participate in International Climate Change Programs

With a complete inventory, countries can:

•	Build technical expertise that can be applied to other climate change
policies and programs

•	More easily access climate financing, such as funds available from the
Global Environment Facility

•	Estimate and report forest-related carbon emissions and removals, which
will help a country prepare for participation in REDD+, an international effort
to create financial value for maintaining or increasing carbon stored from
forests in developing countries

•	Inform Low Emission Development Strategies (LEDS) and Nationally
Appropriate Mitigation Actions (NAMAs) to reduce emissions and promote
economic growth

Use Inventory Data and Analysis
to Support Multiple Priorities

Inventory data and emission estimates can help identify strategies for improving
a country's economy and managing natural resources. In many countries, data
relevant to preparing an inventory is collected for other purposes. If not, data
collected for inventory purposes can be used to support economic development,
natural resource management, and much more. For example:

•	Data on raw material production and energy consumption can be used to
help industry improve processes and increase efficiency

•	GHG emission rates (e.g., emissions per unit of milk or meat production)
can be compared to rates in other countries to identify and address
inefficiencies in livestock management

•	Data on the size and types of forests in your country (and how they change
over time) can be used to promote sustainable harvesting of timber for
wood products, ensuring the long-term viability of the timber industry, while
protecting watersheds and biodiversity and enhancing the tourism industry

•	Data on agricultural practices can be shared with land managers to create
sustainable approaches to food production, agricultural development, and
rural development

National GHG inventories provide a foundation for sustainable development
decisions and growth. A high-quality inventory can support a variety of areas of
activities and programs related to natural resource management, climate change
planning, and economic development, as illustrated in the figure below.
