This paper reviews research across economics, political economy, political science, and public policy to investigate how institutions shape the adoption, implementation, and durability of climate policies. We examine how formal institutions (i) coordinate implementation capacity, (ii) anchor...

This study critically and constructively assesses how 'economic games' contribute to climate policy research via a pre-registered systematic scoping review of 165 sources. Researchers use economic games as empirical tools to measure cooperation while experimentally controlling the presence,...

This paper reviews research across economics, political economy, political science, and public policy to investigate how institutions shape the adoption, implementation, and durability of climate policies. We examine how formal institutions (i) coordinate implementation capacity, (ii) anchor...

The fossil-fuel foreign policy of the United States under President Donald Trump has intensified the conflict between petrostates and electrostates in international climate politics. At COP30 in Belém in November 2025, this cleavage was particularly evident in the dispute over a roadmap for the...

The Paris Agreement is designed to increase climate ambition gradually through a process of ratcheting up. What is the plausible endpoint of this process? We develop a tractable integrated assessment model in which countries interact through a decentralized general equilibrium and negotiate...

The study examines economic growth and climate change when system competition between countries causes drastic changes in their climate policies. The world is divided into two groups of countries: one that implements strict climate policies and another that refrains from doing so due to concerns...

As climate negotiators gathered in Belém for the 30th Conference of the Parties to the United Nations Framework Convention on Climate Change (COP30), the surrounding rainforest was in the spotlight, with COP30 being dubbed a “forest COP”. As one of its key projects, the Brazilian government...

Public support for climate policies that improve the region's resilience is crucial given climate risks. This paper contains the analysis of data from 13,547 respondents across 14 Asian economies, following a survey completed in July 2024. The analysis reveals widespread climate concern (91% of...

As the world approaches global warming tipping points, local climate engagement aims at climate actions that are equitable, effective and aligned with local needs. Strengthening and scaling up these initiatives can amplify impact, though efforts are often fragmented and require strengthened...

Across Africa, rising populations and increased socioeconomic activity in coastal areas are resulting in increasing marine pollution. Rather than expand their Blue Economies, countries need to combat pollution in coastal and marine waters to mitigate the threats posed to biodiversity, ecosystem...

Two phenomena are increasingly reshaping the world economy. One is the growing and well-documented importance of climate transition policies that differ across countries. The other is the stark rise of geoeconomic fragmentation (GEF) concerns. While differences in climate transition policies are...

Countries' current Nationally Determined Contributions (NDCs) under the Paris Agreement leave a substantial gap to the emissions reductions needed to limit global warming to 2°C. Böhringer et al. (2025) showed the large emissions reduction potential of global emissions trading even if...

This paper examines how donor countries can be motivated by self-interest to fund emission reductions in low- and middle-income countries (LMICs). While not solving the broader climate cooperation problem, we propose pragmatic measures that do not require global consensus on future climate risks...

China actively fosters practical green cooperation to advance global sustainable development, and strengthens global environmental governance initiatives, including the implementation of the Sustainable Development Goals (SDGs). However, this approach has often positioned China as more of a doer...

Climate policies do not operate in isolation but propagate through global production networks, affecting industries beyond national borders. This paper combines international input-output data with a granular instrumental variable approach to capture how foreign regulations transmit through...

Carbon pricing is becoming a mainstream tool to cut emissions and drive clean growth. The EU's own Emissions Trading System (EU ETS) has reduced covered emissions by 50% in 20 years while raising over €230 billion euros to support the transition - a success that inspires others. Today more...

The world is falling behind on the Sustainable Development Goals (SDGs), a situation exacerbated by recent geopolitical disruptions and challenges to international cooperation. This policy brief, based on a virtual roundtable in the context of the Hamburg Sustainability Conference (HSC) with...

On 14 July 2021, the European Commission adopted a series of legislative proposals implementing its plan to achieve climate neutrality in the EU by 2050. These included an intermediate target of at least a 55% net reduction in greenhouse gas emissions by 2030. The proposal involved changes to...

In the discussions being held at EU level about the 2040 mitigation target, the role of international credits has recently taken centre stage. The new momentum in those discussions is due in part to the German government having announced its support for a mitigation target of a net 90 per cent...

Since the 2016 Paris Agreement, countries and companies have been increasingly pressured to adopt appropriate response measures to climate change. However, it is not clear what factors drive firms to undertake climate change actions. Using a correlated random effects panel probit model, this...

Purpose - The study focused on the influence of internal environmental communication on organizational environmental governance and the adoption of green inbound logistics practices and the mediating role of organizational environmental governance on the relationship between internal...

The Association of Southeast Asian Nations (ASEAN) is dangerously exposed to mounting climate challenges and is an increasingly significant contributor to their proliferation. The region is highly vulnerable to rising temperatures and sea levels, extreme weather events, and environmental...

Objectives: This paper aims to analyze the relationship between carbon tax implemen- tation and CO₂ emissions reduction in European countries. It also seeks to assess the compatibility of national carbon tax policies with international climate commitments adopted under successive COP...

The focus of climate economics has traditionally been on CO2 as a negative externality. For decades, this has led policymakers to strongly focus on carbon pricing as the preferred climate policy instrument. But addressing the climate crisis differs fundamentally from a pollution problem. It...
