Mostafa Kamal Tolba

Record year1987

summaryDuring the 1987 ozone-protocol negotiations, the FRUS text §§1, 3 records that the interim chair's group, with effective leadership assistance from Tolba, narrowed disagreements over the stringency of controls and the timetable; he prepared compromise text for subsequent negotiations. The draft had not at that time won the agreement of all participating countries and cannot be written as a one-person outcome of treaty, implementation, or environmental benefit.

M rationaleThe text of the US State Department cable dated 1987-05-08, §§1, 3 provides specific group assistance and compromise text on control provisions rather than merely a job title, so it is assessed as institutional-negotiation service at M5.3. The plan had not yet been formally agreed by the delegations at that time; the M covers only a high-leverage but narrow bridging outcome, not the civilizational benefits of the entire Montreal Protocol.

attribution rationaleTolba 0.20; prior work in science and law 0.16; interim chair's group, negotiation, and drafting 0.22; national delegations 0.19; UNEP/secretariat 0.12; technical stakeholders 0.05; unresolved 0.06.

overlap boundaryCredits only the documented leadership assistance in the interim chair's group in 1987, the narrowing of disagreements over stringency/timetable, and compromise text on control provisions for subsequent negotiation; the cable explicitly states that delegations had not yet formally agreed to the plan, so it does not count the final protocol's science, drafting, adoption, ratification, industrial transition, implementation, or ozone-recovery benefits.

Evidence gapsOriginal records of the 1987 meeting and the compromise-text version chain are needed to confirm the scope of his writing, team revision, and final-text adoption.

Record year1975–1976

summaryProposed the ozone-risk programme, advancing scientific monitoring, impact assessment, and sustained intergovernmental coordination.

M rationaleThe Ozone Secretariat has clear records of the scope of Tolba's 1975 proposal and the 1976 action plan, so M5.1 is assigned. Its independent value was to institutionalize scientific risk as a framework for continuing assessment; the 1987 negotiation point consumes only its inputs and does not duplicate general scientific or final-treaty value.

attribution rationaleTolba 0.18; scientific prior work 0.20; UNEP programme team 0.20; scientists 0.17; Governing Council representatives 0.12; UNEP 0.08; unresolved 0.05.

overlap boundaryCount only the ozone-risk programme proposed by Tolba in 1975, and the organizational residue of its conversion through UNEP's collective process into the 1976 World Plan of Action; scientific discoveries, the text and adoption of the 1985 Vienna Convention, the 1987 Montreal compromise negotiations, and subsequent implementation are excluded.

Evidence gapsThe original text of the 1975 proposal, Governing Council deliberations, and the drafting chain for the 1976 action plan are still missing; the individual share cannot be expanded into sole designer of the plan.

Record year1974–1976

summaryParticipated in turning transboundary pollution issues in the Mediterranean into a path of regional cooperation and treaties jointly involving coastal states.

M rationaleUNEP's text explicitly records Tolba and colleagues as participating in the 1975 decision on the treaty route, and positions the MAP/Barcelona system as the foundation of Regional Seas, sufficient to add an institutional-template outcome family at M5.2. This value covers early organization and route selection; it is not raised according to the number of countries subsequently covered or pollution improvements.

attribution rationaleTolba 0.16; marine science and institutional prior work 0.16; UNEP/MAP team 0.20; coastal-state negotiators 0.25; scientific-assessment team 0.09; institutions 0.08; unresolved 0.06.

overlap boundaryCount only the residue of Tolba and UNEP colleagues choosing a coastal-state treaty route and organizing Mediterranean regional cooperation in the early formation of Regional Seas/MAP from 1974 to 1976; the Barcelona Convention text, national adoption, expansion to 18 regional systems, subsequent agreements, and pollution improvements are all excluded.

Evidence gapsRecords of MAP meetings and the drafting chain from 1974 to 1976 are still missing, so a higher individual share for Tolba in the scheme text, budget, and specific institutional design cannot be determined.

Record year1989

summaryIn 1989, Tolba sought views from governments, institutions, and non-governmental organizations in preparation for the next United Nations environmental conference. This was a bounded convening and procedural service; the conference agenda, decisions, funding, and subsequent programmes still belong to the participants, UNEP team, and institutions.

M rationaleThe source provides a specific consultation action in 1989, sufficient to estimate a limited institutional service at M4.5; its scope is narrower than the Montreal compromise text and cannot be raised from the 17-year tenure or the office itself.

attribution rationaleTolba 0.23; secretariat team 0.24; participating governments/institutions/NGOs 0.25; institutional prior work 0.12; UNEP 0.10; unresolved 0.06.

overlap boundaryCount only the 1989 cross-government, institution, and NGO consultation and service of preparing the subsequent environmental conference, explicitly recorded in UNEP narrative materials; do not fold in the entire 1975-1992 tenure as Executive Director, the conference's final resolutions, national policies, or global environmental improvements.

Evidence gapsTerms of reference for the 1989 consultation, the compilation of views, and conference materials are needed to confirm the specific outcome and scope of individual decision-making.
