CO2 emissions from international shipping, which are currently unregulated, are predicted to rise from 2.7% today to 18% in 2050. International bunker fuel emissions have been excluded from any commitment in the Kyoto Protocol; the UNFCCC conference in Copenhagen also failed to bring about clear...

Climate engineering (CE) and carbon capture and storage sub-seabed (CCS-S) are currently controversially debated options to address climate change. Our paper provides empirical evidence on the public perception of two different CE measures, namely, stratospheric sulphate injection (SSI) and...

International cooperation is at the core of multilateral climate policy. How is its effectiveness harmed by individual countries dropping out of the global mitigation effort? We develop a multisector structural trade model with emissions from production and a constant elasticity of fossil fuel...

International trade is highly imbalanced both in terms of values and in terms of embodied carbon emissions. We show that the persistent current value trade imbalance patterns contribute to a higher level of global emissions compared to a world of balanced international trade. Specifically, we...

Oceans regulate our climate, provide us with natural resources such as food, materials, substances, and energy and are essential for international trade, recreational, and cultural activities. Free access to and availability of ocean resources and services, together with human development, have...

Global food markets demand the adoption of food standards by small-scale farmers in developing countries when they enter international markets. While a conventional certification with GlobalGAP can be a market entry condition for conventional food, especially for horticultural products, organic...

It is still difficult for biofuel producers to proof the contribution of their biofuels to reducing carbon emissions because the production of biofuel feedstocks can cause land use change (LUC), which in turn causes carbon emissions. A carbon map can serve as a basis to proof such contribution....

Biodiversity can sometimes only be preserved if natural habitats are excluded from human uses. Such protection measures generate positive externalities at the global scale. This holds especially for protection in developing countries that host great parts of global biodiversity. For...

Nationally implemented protected area measures for biodiversity conservation generate cross-border externalities. For internalizing these externalities at the international level, the Global Environment Facility (GEF) has been established as a multilateral mechanism of transfer. This paper...
