Understanding countries’ net-zero targets
Virtual CCXG Global Forum on the Environment and Climate Change
September 2021
Sirini Jeudy-Hugo (CCXG)
Based on: ‘’“Understanding Countries’ Net-Zero Emissions Targets”, S. Jeudy-
Hugo, L. Lo Re and C. Falduto (2021, draft)
2 Climate Change Expert Group
Outline
• Context and background
• Unpacking countries’ net-zero targets
• How countries are translating net-zero targets into near-term policies
• Conclusions
3 Climate Change Expert Group
Context and background
• To meet the temperature goal of the Paris Agreement, Parties aim to “achieve a
balance between anthropogenic emissions by sources and removals by
sinks of GHGs gases in the second half of this century” (Article 4).
• Supported in 2018 IPCC Special Report and 2021 IPCC Sixth Assessment Report.
• Increasing number of net-zero commitments by countries and non-state
actors, but also a growing gap with near-term actions and open questions.
• Different pathways to reach net-zero with different risks, uncertainties,
challenges and opportunities

NET-ZERO
TARGETS
6 Climate Change Expert Group
Translating net-zero targets into near-term plans
• 31 countries have adopted interim targets on their pathway to net-zero
• NDCs can be a useful tool to periodically set/adjust interim targets to net-zero
• Improved alignment between mid-term (NDCs) and long-term (net-zero) targets
• LT-LEDS, sectoral plans and domestic strategies can support implementation
• Lessons from country experiences in target setting and implementation
7 Climate Change Expert Group
Conclusions
• Growing number of countries’ net-zero targets provide welcome signals of intent,
however targets are diverse and difficult to compare.
• Many details are currently unclear and the devil is in the details as different
approaches could have different outcomes.
• Greater clarity on key dimensions of countries’ net-zero targets, especially
how countries plan to meet their commitments, is important to improve
understanding of different net-zero targets and overall implications for
achieving the temperature goal of the Paris Agreement.

CCXG Forum, September 2021, Sirini Jeudy-Hugo

  • 1. Climate Change Expert Group www.oecd.org/env/cc/ccxg.htm Understanding countries’ net-zero targets Virtual CCXG Global Forum on the Environment and Climate Change September 2021 Sirini Jeudy-Hugo (CCXG) Based on: ‘’“Understanding Countries’ Net-Zero Emissions Targets”, S. Jeudy- Hugo, L. Lo Re and C. Falduto (2021, draft)
  • 2. 2 Climate Change Expert Group Outline • Context and background • Unpacking countries’ net-zero targets • How countries are translating net-zero targets into near-term policies • Conclusions
  • 3. 3 Climate Change Expert Group Context and background • To meet the temperature goal of the Paris Agreement, Parties aim to “achieve a balance between anthropogenic emissions by sources and removals by sinks of GHGs gases in the second half of this century” (Article 4). • Supported in 2018 IPCC Special Report and 2021 IPCC Sixth Assessment Report. • Increasing number of net-zero commitments by countries and non-state actors, but also a growing gap with near-term actions and open questions. • Different pathways to reach net-zero with different risks, uncertainties, challenges and opportunities
  • 4. 4 Climate Change Expert Group Mapping countries’ net-zero targets (as of 11 August 2021)
  • 5. 5 Climate Change Expert Group Unpacking countries’ net-zero targets Sectoral coverage  Economy-wide  Scope unclear  Exclude specific sectors Governance mechanisms  Regular reporting cycles  Independent expert bodies  (High-level) committees Stakeholder engagement  Stakeholder groups  Citizen assemblies Terminology  Net-zero emissions  Climate neutrality  GHG neutrality  Carbon neutrality Scope of GHG emissions  All GHG emissions  Only CO2 emissions  Exclude specific gases  Scope unclear Timeframe 2030 2050 2060+ NET-ZERO TARGETS
  • 6. 6 Climate Change Expert Group Translating net-zero targets into near-term plans • 31 countries have adopted interim targets on their pathway to net-zero • NDCs can be a useful tool to periodically set/adjust interim targets to net-zero • Improved alignment between mid-term (NDCs) and long-term (net-zero) targets • LT-LEDS, sectoral plans and domestic strategies can support implementation • Lessons from country experiences in target setting and implementation
  • 7. 7 Climate Change Expert Group Conclusions • Growing number of countries’ net-zero targets provide welcome signals of intent, however targets are diverse and difficult to compare. • Many details are currently unclear and the devil is in the details as different approaches could have different outcomes. • Greater clarity on key dimensions of countries’ net-zero targets, especially how countries plan to meet their commitments, is important to improve understanding of different net-zero targets and overall implications for achieving the temperature goal of the Paris Agreement.
