Brief 4: Lessons From The Multilateral Trading System For Reforming The Architecture Of The International Environmental Regime, Thomas Cottier, Manfred Elsig, Judith Wehrli Feb 2012

Brief 4: Lessons From The Multilateral Trading System For Reforming The Architecture Of The International Environmental Regime, Thomas Cottier, Manfred Elsig, Judith Wehrli

Governance and Sustainability Issue Brief Series

Recent studies on environmental regimes suggest that important lessons and policy recommendations may be drawn from the functioning of the multilateral trading regime. This brief compares the needs and goals of the trade and environment regimes, and discusses how insights from over sixty years of experience of the multilateral trading system might provide ideas for redesigning the architecture of the international environmental regime. It further calls for a better dialogue and improved complementarities between the two fields in order to enhance coherence within international law.

Ch 21. 'Future Perspectives On Solar Fuels', Thomas A. Faunce Dec 2011

Ch 21. 'Future Perspectives On Solar Fuels', Thomas A. Faunce

Thomas A Faunce

This chapter opens by examining whether the research and development of molecular solar fuels will be characterized in future by its promotion of fundamental societal virtues such as equality and environmental sustainability. As a thought experiment, it presents a vision of some important elements of such a future world—one where energy is primarily not only a matter of global artificial photosynthesis (GAP), but of such virtues. Central to the future perspective presented here is nanotechnological construction with enhanced efficiency of each aspect of the natural photosynthetic process into units capable of inexpensive mass production for domestic use. This involves a …

Governing Planetary Nanomedicine: Environmental Sustainability And A Unesco Universal Declaration On The Bioethics And Human Rights Of Natural And Artificial Photosynthesis (Global Solar Fuels And Foods)., Thomas A. Faunce

Thomas A Faunce

Environmental and public health-focused sciences are increasingly characterised as constituting an emerging discipline—planetary medicine. From a governance perspective, the ethical components of that discipline may usefully be viewed as bestowing upon our ailing natural environment the symbolic moral status of a patient. Such components emphasise, for example, the origins and content of professional and social virtues and related ethical principles needed to promote global governance systems and policies that reduce ecological stresses and pathologies derived from human overpopulation, selfishness and greed— such as pollution, loss of biodiversity, deforestation and greenhouse gas emissions, as well as provide necessary energy, water and …

The Proposed Ban On Certain Nanomaterials For Electrical And Electronic Equipment In Europe: Global Security Implications, Thomas A. Faunce, Hitoshi Nasu

Thomas A Faunce

International collaboration on nanotechnology governance has so far paid little attention to security implications of regulating the use of nanotechnology. For example, the Coalition of Non-Governmental Organizations (initiated by the International Centre for Technological Assessment) developed 'Principles for the Oversight of Nanotechnologies and Nanomaterials' to provide a set of ethical standards for nanotechnology research and development (Kimbrell, 2009). Similar initiatives are observed at the national level, as has been seen in the Swiss Retailers Association Code of Conduct and the UK's Responsible NanoCode (Bowman and Hodge, 2009, pp.149-152). The Organization for Economic Co-operation and Development (OECD) has also been active …
