Special features of the land

sector

Difficult to separate anthropogenic and

natural effects

High uncertainty for some sources and sinks

Possible elements of a long-term vision

Modular accounting framework, applicable to all

IPCC methodologies for reportingBroad coverage of key sources and sinksFlexibility in some aspects“Once in, always in” ruleUp-front informationTechnical assessment processReporting on carbon stocksReporting of qualitative information on

safeguards and landscape approaches

Step 3• IPCC Tier 2 or 3 reporting, high accuracy

• Good data availability, complete time series• Typical contribution type: Economy-wide goal covering the land sector

Module A: Emissions and removals from forestry / land use change

Module B: Non-CO2 emissions from agriculture

Module C: GHG emissions from wetlands

Step 2• IPCC Tier 2 reporting, medium accuracy

• Better data availability, time series data (but with gaps)• Typical contribution type: Sectoral baseline or reference levels


Module B: Non-CO2 emissions from agriculture

Step 1• IPCC Tier 1 reporting, low accuracy

• Limited data availability, fragmented time series• Typical contribution type: Policies and measures, projects



What are the aims and possible elements of a long-term vision for land sector reporting and accounting in the post-2020 climate regime?

Which aspects of the post-2020 land sector reporting and accounting framework should be agreed at the international level, and which should be nationally-determined?
