Crash fault tolerance describes the capability of a distributed system to maintain its proper function despite the occurrence of crashes or failures in one or more of its components. When a distributed system possesses crash fault tolerance, it can be further fortified to achieve Byzantine fault tolerance. Byzantine fault tolerance empowers a distributed system to establish consensus among participants, even when faced with faulty or malicious behavior. Consensus plays a critical role in various tasks, including determining the accurate value of a shared variable, electing a leader, or validating the integrity of a business transaction. Compared to crash fault tolerance, Byzantine fault tolerance instills greater trust because it enables consensus even in the presence of malicious entities. This paper focuses on the performance evaluation of two blockchain solutions that exhibit Byzantine fault tolerance, in contrast to a blockchain solution that demonstrates crash fault tolerance. Specifically, the paper investigates the additional performance requirements associated with the enhanced trust resulting from Byzantine fault tolerance in e-business trading on both national and transnational scales. We analyze the resources needed to operate a business-to-business/business-to-government (B2B/B2G) compliance framework in two distinct geographic scenarios. The first examines the national scale, using Denmark as an example, which is the eleventh largest European country by GDP. The second scenario considers the scale of the European Union (EU) with its 27 member states (plus the United Kingdom). Full article

Hydrogen is fast becoming a new international “super fuel” to accelerate global climate change ambitions. This paper has two inter-weaving themes. Contextually, it focuses on the potential impact of the EU’s new Carbon Border Adjustment Mechanism (CBAM) on fossil fuel-generated as opposed to green hydrogen imports. The CBAM, as a transnational carbon adjustment mechanism, has the potential to impact international trade in energy. It seeks both a level playing field between imports and EU internal markets (subject to ambitious EU climate change policies), and to encourage emissions reduction laggards through its “carbon diplomacy”. Countries without a price on carbon will be charged for embodied carbon in their supply chains when they export to the EU. Empirically, we focus on two hydrogen export/import case studies: Australia as a non-EU state with ambitions to export hydrogen, and Germany as an EU Member State reliant on energy imports. Energy security is central to energy trade debates but needs to be conceptualized beyond supply and demand economics to include geopolitics, just transitions and the impacts of border carbon taxes and EU carbon diplomacy. Accordingly, we apply and further develop a seven-dimension energy security-justice framework to the examples of brown, blue and green hydrogen export/import hydrogen operations, with varying carbon-intensity supply chains, in Australia and Germany. Applying the framework, we identify potential impact—risks and opportunities—associated with identified brown, blue and green hydrogen export/import projects in the two countries. This research contributes to the emerging fields of international hydrogen trade, supply chains, and international carbon diplomacy and develops a potentially useful seven-dimension energy security-justice framework for energy researchers and policy analysts.

Transnational trade holds opportunities for prosperity and development if accompanied by a robust political and legal framework. Yet, where such a framework is missing, transnational trade is frequently associated with, among others, negative impacts on the environment. Applying a legal comparison, this article assesses if recent free trade agreements, i.e., the Mercosur Agreement, CETA and the EU–Vietnam Free Trade Agreement, negotiated by the European Union, have been underpinned with effective environmental standards so that they are in line with global environmental goals and avoid detrimental effects on climate and biodiversity. Besides that, we evaluate the extent to which these agreements at least enable and incentivise environmental pioneering policies in the trading Parties. In particular, we discuss the likely impacts of the agreements on the agricultural sector. The analysis finds that, while a few mandatory standards concerning, e.g., deforestation have been established, overall, the agreements lack a comprehensive legal framework to uphold/enhance environmental protection. Moreover, weak dispute settlement mechanisms to ensure compliance with sustainability measures limits their effectiveness. In addition, the provisions on regulatory cooperation and investor-state dispute settlement are likely to negatively affect the decision-making processes and (thus) discourage ecological pioneering policies in the trading Parties. Hence, there is a long way to go so that transnational trade is compatible with global environmental goals. Full article

Although forestry is not a regulated area in the European Union (EU), numerous decisions in other policy areas are related to forestry. However, its position outside of formal policy-making can result in the fact that actors, such as those within the forest industry, may have a larger role when compared to other policy sectors where the state system has an integrated role. This explorative study reviews the ways in which the forest industry in Sweden, one of the EU states with the most forest land, tries to protect and promote its interests on an EU-level. It concludes that a main way to influence decision-making in the EU is through lobbying, through its own organisations and through the transnational trade association, The Confederation of European Paper Industries (CEPI). The study shows that collectively conducted lobbying is largely preferred which means that internal communication is important since lobbying at the EU-level is potentially limited by the diverging positions of trade association members as well as among the different trade associations themselves.

Important transformations are underway in tropical landscapes in Latin America with implications for economic development and climate change. Landscape transformation is driven not only by national policies and markets, but also by global market dynamics associated with an increased role for transnational traders and investors. National and global trends affect a disparate number of social, political and economic interactions taking place at the local level, which ultimately shapes land-use and socio-economic change. This paper reviews five different trajectories of landscape change in tropical Latin America, and discusses their implications for development and conservation: (1) Market-driven growth of agribusiness; (2) expansion and modernization of traditional cattle ranching; (3) slow growth of peasant agriculture; (4) logging in production forest frontiers; and (5) resurgence of agro-extractive economies. Contrasting trade-offs between economic development and forest conservation emerge across these landscapes, calling for nuanced policy responses to manage them in the context of climate change. This discussion sets the background to assess how reduction of emissions from deforestation and forest degradation and enhancing carbon stocks (REDD+) aims should be better aligned with current landscape trajectories and associated actors to better address climate-change mitigation in forest landscapes with effective and equitable outcomes.
