Intergovernmental Panel On Climate Change (IPCC)

This section of the IPCC AR6 WGIII Technical Summary presents aggregate GHG emissions across global mitigation pathways and projected outcomes from current policies and emissions. It provides a foundational overview of climate action status…

Using a novel climate policy uncertainty (CPU) measure, this study shows that firms reduce future innovation (patents, citations, value) in response to climate policy risk, with green innovation less affected. The mechanism is a precautiona…

Under China's dual carbon goals, this study examines whether the Industry-Finance Cooperation Pilot Policy (IFCPP) enhances both quantity and quality of corporate green innovation. Using staggered DID on Chinese A-share listed firms (2012-2…

Weili Yue, Yasir Rasool

This study analyzes the impact of circular economy (CE) practices on CO2 emissions using panel data from European countries (2000-2022). Results show CE significantly reduces emissions, but its effect is smaller than that of green energy (G…

Dirzka, Christopher

This report analyzes the coherence of the FuelEU Maritime Regulation with related EU policies (ETS, AFIR, RED III) and identifies structural challenges for maritime decarbonization. A hydrogen supply gap constrains e-fuel availability, maki…

This annual review surveys the OECD's environmental law and policy work over the past year, focusing on climate change, carbon mitigation (including the Inclusive Forum on Carbon Mitigation Approaches), climate finance, plastics/circular ec…

Chi FAN

This paper analyzes how digital technologies shape global green trade through a three-dimensional framework of production, distribution, and market/governance. It argues that AI, blockchain, and IoT act as catalysts for green innovation and…

This dataset accompanies a global assessment of climate change mitigation and adaptation strategies implemented across cities worldwide. It enables comparative analysis of urban climate actions, supporting identification of effective approa…

Zheng L.

This paper overviews how G-7 countries are leveraging energy-efficient ecosystems to achieve net-zero emissions. It compares policies and practices, presenting best practices in energy efficiency technologies and policies.

Jordan A.J.

This paper analyzes the evolution of EU decarbonization policies as a dialectical interplay between durability and flexibility. It argues that balancing long-term target commitment with short-term policy adjustments is key to effective clim…

This paper proposes a theory of change for Buy Clean policies, linking interventions (e.g., EPD requirements) to outcomes like reduced embodied carbon and low-carbon market creation, and offers indicators for evaluating policy effectiveness…

Daniel Cassidy, Kelly de Bruin

This paper develops I3E-Transport, an Irish passenger transport model, to evaluate carbon taxation and ICE phase-out policies. Simulations for 2024–2050 show that while a carbon tax yields limited abatement, a comprehensive ICE ban from 203…

Oberthür S.

This paper analyzes the evolution of EU climate policy from emissions trading to the European Green Deal, focusing on policy mix and integration. It examines the role of the EU ETS and policy interactions, offering insights for future clima…

Yanyan Ma, Maomao Yu

This paper uses staggered difference-in-differences to examine China's Intelligent Manufacturing Policy's effect on reducing firms' pollution emission intensity relative to export value. It identifies four transmission channels: improved in…

Daoping Wang, Liying Xin, Yangjingzhuo Liu +1

This paper quantitatively evaluates the impact of local governments' carbon neutrality policies on carbon emissions in China, using a big dataset from 276 cities (2007-2021). Results show these policies effectively reduce emissions, especia…

This update from the UN High-Level Expert Group on Net Zero Emissions Commitments presents revised guidelines for non-state actors such as corporations and financial institutions. It emphasizes integrity, transparency, and robust transition…

Qudrat-Ullah H

This paper argues that long-term sustainability of nuclear energy depends on institutional legitimacy within sociotechnical governance. It develops a Trust-Equity-Transparency-Inclusion (TETI) Index and finds that higher transparency and st…
