(How) Does Diversity Still Matter for the IPCC? Instrumental, Substantive and Co-Productive Logics of Diversity in Global Environmental Assessments

To what extent has the Intergovernmental Panel on Climate Change (IPCC) succeeded in its ambition to shape a more diverse environmental expertise? In ways are diversity important IPCC? What purposes does serve IPCC’s production of global assessments and thus knowledge general? These questions explored by analyzing quantitative demographic data latest two assessment cycles (AR5 AR6) qualitative from semi-structured interview study with IPCC experts. The analysis shows that there have been improvements recent years across measures gender (women comprising 34% authors AR6 compared 21% AR5), regional representation proportion developing countries (35% 31% AR5). not, however, distributed evenly when looking at seniority authors, nor comparing working groups, WGI (the physical science) remaining much less (28% female authors) than WGII (impacts) (41% WGIII (mitigation) (32% authors). interviews suggest rather viewing as challenge it should be viewed an opportunity build capacity. Distinctions between scientific expertise ‘diversity voice’ need reconsidered terms both substantive instrumental value range knowledge, experience skills add process climate knowledge. concluding discussion, three points raised: (i) issue will probably grow importance due fact complex task transforming society increasingly come into focus; (ii) crucial for maintain develop capacity make assessments; (iii) not reduced simply means improving making assessments, but also improve outcomes assessments.
