# Shinichiro Fujimori Back to [[Authors/@BjornLomborg/People/People|Lomborg People]] · [[Authors/@BjornLomborg/BjornLomborg-x-profile|@BjornLomborg]] · Topic: [[Topics/Climate Change Science and Policy Debate/Climate Change Science and Policy Debate|Climate Change Science and Policy Debate]] **Role:** Integrated-assessment modeller; lead developer of the AIM (Asia-Pacific Integrated Model) CGE scenarios that supply the cost side of Lomborg's NetZeroCostBenefit.com - Lomborg's site takes its net-zero cost from the AIM model's net-zero-by-2050 scenario (world GDP 7.2% below current policies in 2050, 7.8% below AIM's 2020-policies run), and draws 81 of its 961 cost scenarios from the AIM scenario archive (cited on the site as Fujimori 2021). See the [[Authors/@BjornLomborg/Post Analyses/Post Analysis - BjornLomborg on NetZeroCostBenefit and EU Net Zero for 0.0268 Degrees (2026-11-10)|NetZeroCostBenefit analysis]] and [[Authors/@BjornLomborg/Post Analyses/Post Analysis - BjornLomborg on Net Zero Not Saving Money and 96 Percent of Scenarios (2026-11-10)|96-percent-of-scenarios analysis]]. - His Objections page also cites Fujimori, Oshiro, Hasegawa, Takakura and Ueda (2023), [Climate change mitigation costs reduction caused by socioeconomic-technological transitions](https://doi.org/10.1038/s44168-023-00041-w) (*npj Climate Action* 2: 9), which finds that behaviour change and other transitions can cut mitigation costs sharply. Lomborg rejects those assumptions; the paper itself is mainstream literature. - Affiliation: Kyoto University and NIES (Japan's National Institute for Environmental Studies) ⚠️ from memory, not re-checked this run. - See also [[Topics/Climate Change Science and Policy Debate/People/Bjørn Lomborg|Bjørn Lomborg]].
