The Extraordinary Luxury of Time • Thanks for the opportunity to deliver a keynote address to the 24 th AIM workshop. • The AIM research team has been at the cutting edge of research for three decades and I’d like to talk about two issues that are on the frontier • One that AIM began work on 2 years ago—Fujimori et al. (2016) • The other is just emerging—45Q 2

The The Va Value of of Arti Articl cle 6 3

The Paris Agreement and Article 6 • The Paris Agreement uses a bottom up approach— Nationally Determined Contributions (NDCs) • Each member of the agreement determines what it can contribute to achieving the goals of the Paris agreement • Article 6 allows countries to jointly implement NDCs paris ‐ agreement ‐ and ‐ article ‐ 6/ Source: http://www.carbon ‐ mechanisms.de/en/introduction/the ‐ 4

How Valuable is Article 6? What is the potential economic value of implementing Article 6? • What is the potential size of the carbon market? • Who would be the sellers and who would be the buyers? • How much could costs be reduced? • How much additional ambition is enabled by cost reductions?

How much additional ambition could be enabled by cost reductions? Global CO 2 Emissions • We assume that the cost that 2030 40 each region is willing to 11% Reductions contribute to emissions mitigation is reflected in their 35 NDC, • We sum the costs and then Gt CO 2 assume that in each period, 30 the world limits emissions using Article 6 mechanisms. 25 • Each country increases its ambition so that its net cost, after trade, is identical to its 20 net cost under the I-NDC scenario. 2010 2025 2040 2055 2070 2085 2100 • Something more easily done in Independent Mitigation a model than the real world.

How Valuable is Article 6? • Article 6 holds significant potential to reduce cost and enhance ambition • Everyone could be better off through collaboration • 2030 global net benefit ~$270 billion • Realizing this potential is a real- world challenge • Near-term : Translating NDCs to Internationally Transferred Mitigation Outcomes (ITMOs) • Long-term : It could take any number of forms including NDC coalitions, ratchet mechanisms, or Source: https://unfccc.int/files/focus/long ‐ term_strategies/application/pdf/mid_century_strategy_report ‐ final_red.pdf other novel approaches. 17
