Controversy has been sparked by
the perceived ambiguity or impracticality of the precautionary principle, the potential for its operation
to conflict with trade, economic or development priorities, cost implications of its adoption, the wide
discretionary leeway it allows decision makers, and the potential for this leeway to allow imposition of
particular environmental values or disguise trade-protectionist abuse. There has been wide
distrust of the principle, lack of clear or shared understanding of its meaning or relevance, little
analysis of its on-the-ground impacts, and scant guidance available for its application. Furthermore, while a range of concerns has been articulated by developing countries, the active policy debate over precaution has been largely dominated by corporate and environmental voices from developed countries.
