Environmental Role-Play:

Global Management of Organochlorines


Lawrence Susskind, Sarah McKearnan, Mike Gordon, Adil Najam, Joshua Secunda, Granville Sewell, Parag Shah and Andrea Strimling

Thirteen-person, multi-issue facilitated negotiation among eight country representatives, four NGO representatives, and a working group chairperson must draft a treaty aimed at reducing harmful organochlorines; also known as "Chlorine Game"


Please note: you must order a copy (a.k.a. license/usage fee) for every person participating in the simulation in your course. This simulation has multiple roles, so you will be unable to complete your purchase without meeting the minimum quantity requirement of copies per role.

Soft copy vs. hard copy

You may order this role simulation in either soft copy (electronic) or hard copy (paper) format. If you select the soft copy option, you will receive an e-mail with a URL (website address) from which you may download an electronic file in Adobe Acrobat PDF format. You will have one week to download your materials from when you receive the email. You are then only authorized to use, print, or share the materials as many times as the number of copies you purchase. The TNRC charges for use of this simulation on a per-participant basis. Therefore, you must purchase a separate copy of this simulation for each person who will be participating, regardless of the number of roles in the simulation. You will only receive a link to one electronic file, which includes all general instructions, confidential instructions, and any teaching notes for the simulation. You should separate out the instructions before distributing to participants.

If you select the hard copy option, you will receive paper copies of this role simulation via the shipping method you select.

For additional information about the soft copy option, please visit our FAQ section, or contact the PON Teaching Negotiation Resource Center at tnrc@law.harvard.edu or 800-258-4406 (within the U.S.) or 301-528-2676 (outside the U.S.).

Please note: At the present time, Teaching Negotiation Resource Center soft copies are compatible with the following versions of the Adobe Acrobat Reader: English, German, French, Spanish, Swedish, Portuguese, Japanese, and Korean. If you have a different version of the Acrobat Reader, you may wish to download one of these at http://www.adobe.com/products/acrobat/readstep2.html, or contact the PON Teaching Negotiation Resource Center at tnrc@law.harvard.edu, 800-258-4406 (within the U.S.), or 301-528-2676 (outside the U.S.) for further assistance. This restriction does not apply to the freely available Teacher’s Package Review Copies.

Ordering a single copy for review

If you wish to review the materials for a particular role simulation to decide whether you’d like to use it, a PDF, or soft copy, version of the Teacher’s Package for the simulation is available as a free download from the description page of most role simulations and case studies. All Teacher’s Packages include copies of all participant materials. In addition, some Teacher’s Packages (but not all) include additional teaching materials such as teaching notes or overhead masters.

Ordering copies for multiple participants

To order multiple copies of a role simulation for use in a course or workshop, simply enter the total number of participants in the box next to “Quantity.” There is no need to calculate how many of each role is required.

If you are ordering hard copies, the Teaching Negotiation Resource Center will calculate the appropriate numbers of each role to provide, based on the total number of participants. For example, if you wish to order a 2-party role simulation for use with a class of 30 students, you would enter “30” in the box next to “Quantity.” You then would receive 15 copies of one role and 15 copies of the other role, for use with your 30 participants. As another example, if you ordered 30 participant copies of a 6-party role simulation, you would receive 5 copies of each role.

In the event that the number of participant copies you order is not evenly divisible by the number of roles in the simulation, you will receive extra copies of one or more roles. Participants receiving the extra roles may partner with other participants playing the same role, thus negotiating as a team. So, for instance, if you ordered 31 copies of a 2-party role simulation, you would receive 15 copies of the first role and 16 copies of the second role. One of the participants playing the second role would partner with another participant playing that same role, and the two would negotiate as a team.

Also known as Chlorine Game


In light of recent evidence indicating that organochlorine compounds may pose serious risks to human health and the environment, the Director of the United Nations Environment Programme (UNEP) has decided to gather a Working Group composed of representatives from eight countries, as well as four representatives from various relevant non-governmental organizations to produce a draft of an international treaty which would call for a phase out some of the most harmful organochlorines. Such a process entails resolution, at some level, of the scientific issues surrounding the potential dangers of widespread chlorine usage. Some argue that scientific evidence pointing to the dangers of chlorine is inconclusive, while environmental activists cite the issue as urgent. The issues that must be addressed are (i) how quickly and at what cost should organochlorines be phased out; (ii), which parties should bear the cost of the phase out; (iii) how should the Working Group be administrated and (iv) what impact should NGO’s have on the Working Group.



  • Underscores the relevance of general lessons about the "basic" skills of negotiations as they apply to multi-party, multi-issue negotiation: i.e. active listening, improving one's BATNA, focusing on interests instead of positions, inventing options of mutual gain, etc.
  • Enhances understanding about political dynamics and substantive outcomes likely to merge during an actual negotiation of a global treaty on organochlorines. Provides a means for exploring the technical, political and economic issues likely to be at stake in such a treaty negotiation.
  • Imparts an understanding of the dynamics of international environmental treaty negotiations as they are currently conducted.
  • Identifies who the critical actors in international environmental treaty negotiation are, what kinds of interests they bring to the table, why these interests are often seen to be in conflict, and how they might potentially be reconciled through a process of joint problem-solving.
  • Emphasizes the importance of understanding the interests of internal constituencies and designing negotiation strategies which manage the link between internal and external negotiations. This game also teaches the importance of creating external coalitions without letting internal coalitions crumble.
  • Demonstrates the value of organizing informal dialogue as a precursor to the formal convention-protocol treaty-making process.



This is a highly intensive exercise with considerable logistical requirements. A room with seating for 13 (or 25 depending on the number of participants) is required. Parties should be able to hear each other and the use of microphones is sometimes necessary. At least one break-out room is suggested. Given the long duration of this exercise, refreshments are also advised. This lengthy, complex case requires several hours of preparation time as well as several hours of negotiation time. Teaching staff are advised to be particularly well versed in these materials before commencing this game. Estimated Time Requirement8 hours spread over 2 days. The game can be played in an alternative short version which takes about 4 hours.
