This study compares evaluations of 14 game-changing climate innovations by 260 global experts against LLM-generated personas from ChatGPT, Gemini, and Claude, prompted with matching occupational, geographic, and gender traits. LLMs showed f…

Wegener, Moritz, Neuwahl, Frederik, Salvucci, Raffaele +5

Presents energy-supply findings of the CETO2026 deep-decarbonization pathway for the EU, built with the POTEnCIA hybrid model and aligned with the European Climate Law. Electricity demand more than doubles to over 6000 TWh by 2050, with win…

This study builds AFOLU-India, a model recalibrated for Indian agriculture, to project GHG emissions to 2050 and assess mitigation potential and abatement costs across four scenarios. Emissions rise from ~345 Mt CO2eq (2005) to 390–505 Mt b…

Modi, Dhruv, Kennedy, Kathleen, Zhao, Alicia +3

This paper develops an automated vetting toolkit to diagnose and correct state-level input calibration in GCAM-USA, an integrated assessment model. It combines EIA API data retrieval, output harmonization, diagnostic visualization with algo…

Fragkiadakis, Dimitris, Manfroni, Michele, Fragkiadakis, Kostas +1

This study quantifies socio-economic implications of EU industrial decarbonization to 2050 using the GEM-E3 CGE model, extended with a technology-rich steelmaking module and a dedicated industrial CCS module. Comparing a frozen policy pathw…

Chanda, Debmallya, Peralta, Catarina, Verdolini, Elena +1

This paper adds a dedicated digital-services sector to the WITCH integrated assessment model, capturing digitalisation's dual role of raising electricity demand while boosting energy productivity. Digital services are produced from digital …

Kim, Haein, Kim, Yong-Gun, Jung, Tae Yong +1

This study soft-links a global CGE model (UNICON-G) with a bottom-up power optimization model (UNICON-POWER) to assess hydropower degradation in Laos, Thailand, and Vietnam under deep decarbonization. A ~20% hydropower shortfall by 2040 rai…

Alexander, Kling, Holtz, Georg

Uses ITOM-Cement, a bottom-up optimization model covering site-level clinker kilns to regional milling, to assess EU27+UK cement decarbonization pathways. It highlights three cross-sector dependencies—steel slag as SCM, competition with pet…

Madianos, Michail, Fragkos, Panagiotis, Baka, Maro +4

A review of 77 integrated assessment and energy system models finds agriculture is widely simplified as a static land-use emissions source rather than a dynamic energy consumer. The authors classify agricultural operations into pre-producti…

Neumann, Rebecca B

Tracing CDR estimates across 51 sources and IPCC scenarios, this study shows the widely cited 10 Gt CO2/yr durable CDR target did not derive from direct reading of IPCC outputs. It originated as an informal 2017 news estimate, was declared …

This study examines how ancillary services revenue affects the valuation and bankability of green hydrogen investments. It appears to integrate grid-service income streams into hydrogen project economics. Methodological details and findings…

Byeongho Yu, Dongsu Kim, Heejin Cho +2

This paper addresses building decarbonization through electrified thermal management, combining a VRF heat-recovery system with domestic hot water integration. It targets improved energy efficiency and reduced fossil-fuel dependence in buil…

Thant Zin Aung, Adriana Saraceni, Bart Vos +4

This paper examines how the EU's three main decarbonization policies should be realigned through a life cycle perspective, and what this implies for the sustainability of urban logistics. It argues for greater policy coherence and broader s…
