  • Points to make: Easier to estimate impact of some types of contributions than others (estimate both future emissions levels to see how going wrt 2C, estimate emissions reductions from action, to understand effort, equity). Points to trade-off between participation and ex-ante understanding. BOUNDED FLEXIBILITY.Unique information needsE.g. baseline for BAU goal -> concept of BOUNDED FLEXIBILITYE.g. energy efficiency goal, need to understand what target is, how will be measured, AND what it means in terms of GHGsE.g. LULUCF – should we have a common approach? In Kyoto, all these functions integrated – but this doesn’t allow non-GHG targets, baselines, or long-term transformation.
  • Transcript

    • 1. Climate Change Expert Group www.oecd.org/env/cc/ccxg GHG or not GHG: Accounting for diverse mitigation contributions in the post-2020 climate framework Christina Hood (IEA) Based on the draft discussion paper by C. Hood, G. Briner and M. Rocha CCXG Global Forum 19 March 2014, Breakout Group B
    • 2. 2 Climate Change Expert Group Outline: Session 1 (9.30-11h) Functions and elements of accounting Exploring accounting for different types of mitigation contributions  GHG and non-GHG contributions
    • 3. 3 Climate Change Expert Group GHG framed contributions Expressed relative to base year, baseline (e.g. BAU or GDP), or as a fixed level Non-GHG contributions that have a short-term impact on GHG emissions  E.g. renewable energy, energy efficiency, forest cover Contributions targeting long-term transformation  E.g. infrastructure investment or regulation, technology development Diverse mitigation contributions
    • 4. 4 Climate Change Expert Group Mitigation contributions Actual national emissions levels ex ante ex post Track via GHG inventories Enable understanding of intended mitigation contributions and their GHG impacts Track progress in implementation of mitigation contributions and their GHG impacts Understand (or avoid) expected transfers of GHG units within or between Parties that could lead to double counting Track actual transfers of GHG units within or between Parties NationalscaleGlobalscale Functions of an accounting framework
    • 5. 5 Climate Change Expert Group Headline number Type Period applied Scope Base year or baseline Expected mitigation transfers Ex ante description of GHG mitigation contribution GHG inventories Accounting for land use sector emissions / removals Actual transfers of mitigation outcomes (via market or non- market approaches) Ex post tracking of progress towards GHG mitigation contribution exanteexpost Accounting for GHG contributions Prag, Hood and Barata (2013)
    • 6. 6 Climate Change Expert Group Headline number Information needed to estimate expected GHG emissions reductions Other specific information, depending on contribution type Expected mitigation transfers Ex ante description of non-GHG mitigation contribution GHG inventory Actual mitigation transfers (market or non- market) Ex post tracking of progress towards non-GHG mitigation contribution exanteexpost Track progress in implementation of non-GHG contribution Ex post understanding of GHG emissions levels and emissions reductions achieved Conversion to GHG Contribution converted to GHG impact Accounting for non-GHG contributions
    • 7. 7 Climate Change Expert Group There could also be a package of non-GHG and long-term contributions either To support delivery of GHG contribution As stand-alone goals Understanding multiple contributions ex-ante ? Assess expected GHG reductions as a package Assess consistency of GHG and non-GHG contributions Multiple mitigation contributions
    • 8. 8 Climate Change Expert Group A common approach? Extension of KP-style “activity” accounting Land-based (UNFCCC inventory) approach Extend concept of reference levels to other activities … or a choice between several standard approaches? Approaches to land use accounting
    • 9. 9 Climate Change Expert Group Questions for discussion  Could some mitigation contributions be expressed only in terms of non-GHG metrics?  For contributions not expressed as an absolute GHG quantity, how important is ex-ante estimation of expected GHG impacts, in addition to ex-post tracking of actual GHG emissions?  How could countries receive recognition for actions that are likely to reduce emissions in future, but not in the short term?
