International Climate Policy and Politics

How do geopolitics, populism, and global power relations influence international climate politics? Our researchers analyse these interdependencies and examine how countries of the Global South can promote sustainable development to engender fairer and more effective climate policy worldwide.

    Co-Creating Narrative-Based Near-Term Climate Predictions to Prepare for Volatile Future Climates (part of Excellence Cluster CLICCS / Phase II)

    The Cluster of Excellence “Climate, Climatic Change, and Society” (CLICCS), based at Universität Hamburg, is guided by the overarching question: "Which climate futures are possible and which are plausible?" This GIGA co-led project in the cluster's second phase aims to enhance the use of near-term climate predictions through the use of narratives, where effective narratives are not only founded in climate dynamics, but - through an iterative process - co-created with societal actors.

    Renewables and Carbon Offsets in the Global South: Impacts and Social Conflict (part of Excellence Cluster CLICCS / Phase II)

    The Cluster of Excellence “Climate, Climatic Change, and Society” (CLICCS), based at Universität Hamburg, is guided by the overarching question: "Which climate futures are possible and which are plausible?" This GIGA co-led project in the cluster's second phase investigates the socioeconomic and distributional impacts of renewable energy expansion and land-based carbon offsets in the Global South. It also scrutinises how these impacts lead to new or reinforce existing social conflicts.

    Leibniz Lab Systemic Sustainability

    The rapid loss of biodiversity and ongoing climate change are also the result of intensive agriculture. At the same time, they jeopardize agriculture and food security. The Leibniz Lab "Systemic Sustainability" brings together relevant knowledge in science and society on this fundamental challenge in order to promote the development and implementation of systemic solutions.

    Critical Intervention Points for European Adaptation to Cascading Climate Change Impacts

    A new study maps cascading climate risks to the European Union using stakeholder-driven impact chains and network analysis. It offers country-specific profiles and highlights key intervention areas—like water, livelihoods or violent conflict—to guide coherent, targeted adaptation policies.

    The Poverty and Distributional Impacts of Carbon Pricing on Households: Evidence from Ghana, Nigeria and Uganda

    How do carbon taxes affect African households? Evidence from Ghana, Nigeria and Uganda reveals that domestic carbon pricing is progressive overall, yet low-income households remain vulnerable—unless compensated. Our findings highlight how targeted transfers can offset welfare losses and even reduce poverty.

    Global Carbon Markets and Rural Development in Madagascar

    Carbon offset projects promise to benefit both climate mitigation and rural communities in the Global South. Evidence from Madagascar, however, showcases that three key constraints pose a challenge to the development potential of nature-based offsets in the voluntary carbon market.

    BRICS: Architekten einer neuen Weltordnung?

    Im 21. Jahrhundert vollzieht sich ein fundamentaler Wandel von einer unipolaren zu einer multipolaren Welt. Im Zentrum dieser Entwicklung steht die BRICS-Gruppe. Was 2001 als ökonomischer Verbund begann, ist heute ein komplexes Bündnis mit weitreichenden Ambitionen: Die Reform globaler Governance-Strukturen, die Herausforderung der westlichen Dominanz und die Schaffung alternativer Finanzsysteme – eine Veranstaltungsreihe mit der Landeszentrale für politische Bildung Hamburg.

    Social Impacts of Climate Change in Iraq, American University of Iraq, Baghdad Organisers: German Institute for Global and Area Studies (GIGA), GIGA Institute for Middle East Studies, American University of Iraq - Baghdad Prof. Dr. Eckart Woertz (Speaker)

    Prof. Dr. Eckart Woertz discussed climate change’s impact on food security in Iraq, highlighting a striking consensus: political crisis and poor governance were seen as the most critical threats to food security, even more so than water scarcity and climate Change.
