Task Force on National Greenhouse Gas Inventories

Views on IPCC TFI contribution to
implementation of Paris Agreement
IPCC Side Event: 2006-2016: 10 years of the 2006 IPCC Guidelines
Way forward to support the Paris Agreement

Eduardo Calvo
IPCC Task Force on National Greenhouse Gas Inventories

Background (1)• Methodologies to estimate GHG emissions
and removals that were developed by IPCC
are used or referenced at various levels.
– Not only for National GHG inventories (BRs,
BURs, NCs)
– But also for:• Clean Development Mechanism under the KP• REDD+

New Supplementary Guidance in 2013

Background (2)＋Currently, Non Annex I Parties use theseunder the UNFCCC.
Non-Annex I Parties are encouraged
to use GPGs.

1995 IPCC
Guidelines

GPG2000

GPG2003(non-LULUCF)(LULUCF)

Annex I Parties must use
from 2015
2006 IPCC
Guidelines

Revised 1996 IPCC
Guidelines

Actually, 2006 Guidelines are being usedby more and more Non-Annex I Parties.
Revision/Update by the IPCC

Paris Agreement (1)Paragraph 31, Decision 1/CP.21

Mitigation• Requests the APA to elaborate guidance foraccounting for Parties’ NDCs for consideration
and adoption by CMA1, which ensures that:– (a) Parties account for anthropogenic emissions
and removals in accordance with methodologies
and common metrics assessed by the IPCC
and adopted by the CMA1;

Paris Agreement (2)Article 13, paragraph 7

Transparency• Each Party shall regularly provide thefollowing information:– (a) A national inventory report of anthropogenic
emissions by sources and removals by sinks ofgreenhouse gases, prepared using goodpractice methodologies accepted by the
IPCC and agreed upon by the CMA1;

Paris Agreement (3)• A key input into the global stocktake will comefrom the enhanced transparency framework foraction and support and other relevant inputs from
Parties (including national GHG inventory).
• In order to build mutual trust and confidence andto promote effective implementation of the Paris
Agreement, an enhanced transparency
framework for action is required and for that,
good quality and credible GHG inventory
estimates are essential.

IPCC-43 (Nairobi, 11-13 April 2016)• Approved the TFI’s proposal on Refinement of 2006
IPCC Guidelines, including production of a Methodology
Report(s) [IPCC-XLIII/Doc. 6, Corr.1].
– Refinement of the current available guidance is necessary inorder to provide an updated and sound scientific basis for
future international climate actions, particularly those under
the Paris Agreement.
– Refinement work will not revise the 2006 IPCC Guidelines,
but will provide an update, supplement and/or elaboration of
the 2006 IPCC Guidelines.

Methodological work in support of
the Paris Agreement• Methodology Report(s) to refine the 2006 IPCC
Guidelines– Final draft will be considered for adoption/acceptance by
IPCC at the session in May 2019.
(= 4 years prior to the 1st Global Stocktake)• Other tools (Supporting Materials) such as EFDB, IPCC
Inventory Software, FAQ website– Continuously improved and updated.

Possible relevance to other work
• Some areas of expertise which are required to produce
a Special Report on 1.5oC may be related to TFI, e.g.:– Climate drivers, emission pathways, forcing scenarios, andrelationship with the transparency framework– Adaptation/mitigation costs, trade-offs and co-benefits;
adverse impacts of human response measures; including
emission feedbacks– Transformation pathways including emission trends anddrivers, transparency in reporting, timing, technology
transitions and societal aspects– Negative emission technologies, including carbon
capture, utilisation and storage
