The Paris Agreement of 2015

• Adopted by consensus on 12 December 2015; (Entered into force 4 November 2016)

• A global goal: “Holding the increase in the global average temperature to well below 2°C above pre-industrial levels and pursuing efforts to limit the temperature increase to 1.5°C above pre-industrial levels”

• But the (Intended) Nationally Determined Contributions (NDCs) form main mean of implementation

Article 14“The Conference of the Parties … shall periodically take stock of the implementation of this Agreement to assess the collective progress towards achieving the purpose of this Agreement and its long-term goals (referred to as the ‘global stocktake’)”

• First “test” stocktake in 2018… Talanoa dialogue• For 1,5 deg C difference 2018 – 2023 is crucial• Countries are now formulating their mid-century strategies

First Global Stocktake in 2023 and every five years thereafter; they will assesss progress towards achieving the overall objectives. • Inform Parties in updating and enhancing their NDCs• Intended to increase ambition

• Oriented around three questions:• Where are we?• Where do we want to go?• How do we get there?

• Input 1.5 deg C report and evidence via the portal (stocktake gets IPCC AR report)• Intention stimulate to further enhance ambition, no name calling• Integrated assessment models can contribute to this process

How can we contribute

• Global pathways consistent with the overall objective (where do want to go?)

• Assessment of the total contribution of national policies, NDCs and MCSs (where are we?)

• Assessment of the gap (where are we?)• Comparison of work at the global and national level (where are we?)

• Suggestions on how the gap can be closed (How do we get there?)

• Assessment of the gap (where are we?)

• Current policies reduce GHGs by 3.5 GtCO2‐eq [2.0 to 5.5]

• Policies fall short of NDCs: 11.2 [7.0‐7.0] GtCO2eq.

• Gap with : • 2°C : 23.7 [9.0‐37.4]

How can we contribute• Comparison of work at the global and national level (where are we?)

Regional carbon budgets (2010-2050)

In all regions large gap between 1.5/2 and current policies

Further strengthening needed in all countries

Some countries close to meeting NDC, but those have larger gaps with Paris target scenarios

• Restrictions on new coal and gas power plants w/o CCS

• Energy efficiency improvements in industry and buildings

• Upscaling of industry CCS

• Fuel efficiency improvements in road transport and aviation

• Increase of electric vehicle share

• More efficient use of nitrogen in agriculture

• Eliminating deforestation and 10 mio ha/yr afforestation

• Moderate carbon pricing

How to strengthen this role?

• Dialogue workshops between IAM modellers and policy makers and otherstakeholders

• Cooperation with other research communities (transition sciences)• Service scenarios (annual updates)• Focus more on the opportunities/obstacles at the national level

This project has received funding from the European Union’sHorizon 2020 research and innovation programme under grantagreement No 642147 (CD‐LINKS).

ClimateWorks and UMD

• Starting to explore the idea of an independent Global Stocktake

• 1st scoping workshop in Bonn, May 9 of 2018

• Initial meetings focus on assessing interest

• Multiple interests and sensitivities
