Stockholm Treaty Lab


The Stockholm Treaty Lab Prize

Who can draft the international treaty with the greatest potential to encourage investment in climate change mitigation and adaptation?
Outcome announced
Global Exposure

Challenge Overview

Ambitious targets for curbing global warming were laid out in the 2015 Paris Agreement and the Sustainable Development Goals. Targets that, if they are to be met, will require investments amounting to trillions of dollars across the globe. Renewable energy must become even more affordable and available; energy-efficient transportation will be needed to carry an increasingly mobile world population; sustainable agriculture and forest restoration must substitute unsustainable land use and deforestation; and climate-resilient infrastructures must be built where global warming and rising sea levels already put communities at risk.

To some extent, the technologies necessary already exist – solar and wind power, energy-efficient vehicles, and carbon capture and storage – but enormous investments are needed to deploy these on a meaningful scale. In other areas, existing technologies fall short, and investments must be made in innovation and development. Such “green” investments present exciting and lucrative opportunities for investors.

Foreign investments tend to increase where they are protected by a stable and transparent legal framework, including a neutral and reliable enforcement mechanism. In the absence of such a framework, investors are often hesitant to deploy their funds. Yet no international legal instrument exists that specifically incentivizes and protects green investments. It is against this background that the SCC and its partners are launching the Stockholm Treaty Lab Prize  – an innovation prize that aims to address the “policy gap” between the objectives of the international climate change agreements, and the outcomes that those agreements envision.

The Stockholm Treaty Lab Prize will be awarded to the contestant team that drafts a forward-looking, innovative and workable model treaty that aims to encourage investment in climate change mitigation and adaptation. A treaty that, if implemented, would create transparent, stable and enforceable investment policy regimes. A treaty that has the potential to encourage investors to fund low-carbon projects, support technological innovation, and otherwise invest in a sustainable future.

One month before the submission deadline!

Jan. 26, 2018, 12:48 a.m. PST by Stockholm Treaty Lab

Dear Stockholm Treaty Lab participants,


With one month to go before the February 28 (at 23.59 CET) submissions deadline, we hope that drafting is going well for all of you. As I am sure you know by now, your entries should contain three documents: (1) the text of the Model Treaty, (2) argumentation demonstrating how the Model Treaty meets the assessment criteria (max. 25 pages) and a brief introduction of the contestant team. No more and no less.


Who selects the winner?

The jury members, whose job it will be to review the submissions and select a winner, had their first meeting on January 9. They are:

  • David W. Rivkin is a Partner at Debevoise & Plimpton and the Immediate Past President of the International Bar Association (IBA).
  • Per Klevnäs is a Partner at Material Economics. He previously worked at the Stockholm Environment Institute and the New Climate Economy.
  • Michael Lazarus is the Director of the U.S Center of the Stockholm Environment Institute and an expert in energy and environmental analysis.
  • Mutchucumaraswamy Sornarajah is Professor of Law at the National University of Singapore and has authored several books on public international law.
  • Annette Magnusson is Secretary General of the Arbitration Institute of the Stockholm Chamber of Commerce and the driving force behind the Stockholm Treaty Lab Prize.


A few words about the jury’s work

After the contestant teams submit their entries through the HeroX platform, the secretariat will review the submissions for completeness. To allow the jury to make a blind review, the names and affiliations of team members will be removed before the submissions are forwarded to the jury. Each jury member will evaluate all submissions against the assessment criteria and make a short list of five entries. In April, the jury will meet to select a winner from among the short-listed teams. We hope to announce the winner in May!


Promoting the Model Treaty from New York to Davos

The Treaty Lab team will work hard to ensure that the winning model treaty gets broad exposure and the attention of global stakeholders. This will include – but not be limited to – the following opportunities:


Good luck finalizing your submissions. We look forward to receiving them!


With great excitement,

the Stockholm Treaty Lab team


Model Treaty judging criteria reminder

Nov. 1, 2017, 1 p.m. PDT by Liz Treadwell


I'm sure everyone is working hard on their Model Treaty submissions, so I wanted to send along a reminder of what the judging criteria is. To maximize your points, your Model Treaty must effectively address each of these areas:


  • Compatibility (20 points). The Model Treaty is compatible with the Paris Agreement and the Sustainable Development Goals. It aims to facilitate states’ achievement of the climate-change objectives set out in those instruments. The Model Treaty is also compatible with fundamental principles of property law. 
  • Efficacy (20 points). If adopted by states, the Model Treaty will lead to a significant increase in green investments related to climate change mitigation and adaptation. To this effect, the Model Treaty proposes incentives and protections that serve foreign investors’ needs and interests. The claimed efficacy of the proposed incentives and protections is supported by research and data.
  • Viability (20 points). The Model Treaty is likely to be adopted by states around the world. Adoption is likely because the Model Treaty serves the states’ needs and interests, facilitates the achievement of climate-change goals, and does not unduly restrict the states’ ability to legislate and regulate.
  • Universality (20 points). The Model Treaty appeals to the potentially diverging interests of states and investors in different parts of the world. Where necessary, the Model Treaty includes alternative provisions from which contracting states may select the most appropriate based on context and circumstances.
  • Enforceability (20 points). The Model Treaty is binding and enforceable. It contains an effective dispute resolution mechanism, through which both investors and states can bring claims related to the Treaty.

If you need any clarification, you can email the HeroX team at or post a new topic in the Forum.


Have a wonderful day!
