Generic ecological impact assessments of alien species in Norway: a semi-quantitative set of criteria

The ecological impact assessment scheme that has been developed to classify alien species in Norway is presented. The underlying set of criteria enables a generic and semi-quantitative impact assessment of alien species. The criteria produce a classification of alien species that is testable, transparent and easily adjustable to novel evidence or environmental change. This gives a high scientific and political legitimacy to the end product and enables an effective prioritization of management efforts, while at the same time paying attention to the precautionary principle. The criteria chosen are applicable to all species regardless of taxonomic position. This makes the assessment scheme comparable to the Red List criteria used to classify threatened species. The impact of alien species is expressed along two independent axes, one measuring invasion potential, the other ecological effects. Using this two-dimensional approach, the categorization captures the ecological impact of alien species, which is the product rather than the sum of spread and effect. Invasion potential is assessed using three criteria, including expected population lifetime and expansion rate. Ecological effects are evaluated using six criteria, including interactions with native species, changes in landscape types, and the potential to transmit genes or parasites. Effects on threatened species or landscape types receive greater weightings

Subsidy Regulation in WTO Law: Some Implications for Fossil Fuels and Renewable Energy

This contribution discusses WTO subsidies disciplines in the context of the energy sector. After laying out the relevant disciplines, it will discuss the paradox of WTO law with respect to subsidies towards fossil fuels vis-à-vis those towards renewable energy. It is clear that subsidies on clean energy production and consumption are needed to correct market failures and to promote legitimate policy goals such as contributing to sustainable development through the scale up of clean energy, including expanding its trade.2 However, experience has shown that support schemes for clean energy by their nature and design make them sensitive to WTO dispute settlement. Much more harmful subsidies on fossil fuels, on the other hand, are omnipresent yet often escape being addressed in the multilateral trading system. The contribution will draw upon the examples of ‘energy dual pricing’ and Feed-In Tariffs (FITs). It will argue that while it may be difficult to tackle fossil fuels subsidies in the WTO forum, more efforts are needed to (re)legalise environmental subsidies
