17 September 2010

On August 2, 2010, the Ecuador Court hearing the lawsuit brought by 30,000 rainforest residents against Chevron issued an Order directing both Chevron and the affected communities to submit a document setting forth and justifying their positions on the economic value of the damages. In accordance with the Court's Order, the Ecuadorian communities submitted a legal brief along with six Annexes prepared by environmental, economic, and medical consultants retained by the communities. These expert valuation assessments were submitted to add additional scientific analysis and insight for the Court on the issue of damages utilizing evidence in the record and from relevant public studies. This document is a summary of these supplemental analyses.

A 2005 letter signed by fifty eminent scientists and doctors from across Latin America, North America and Europe defending the approach used in these analyses to study health effects and decrying Chevron's "apparent interest in protecting itself by undermining the Amazonian people's quest for environmental justice" can be found here.
