The Economics of Ecosystems and Biodiversity

The Economics of Ecosystems and Biodiversity (TEEB) is a study led by Pavan Sukhdev. It is an international initiative to draw attention to the global economic benefits of biodiversity. Its objective is to highlight the growing cost of biodiversity loss and ecosystem degradation and to draw together expertise from the fields of science, economics and policy to enable practical actions. TEEB aims to assess, communicate and mainstream the urgency of actions through its five deliverables—D0: science and economic foundations, policy costs and costs of inaction, D1: policy opportunities for national and international policy-makers, D2: decision support for local administrators, D3: business risks, opportunities and metrics and D4: citizen and consumer ownership.

One motive for the study was to establish an objective global standard basis for natural capital accounting. Estimates establish the cost of biodiversity and ecosystem damage expected to cost 18% of global economic output by 2050 [1] and currently at over US$2T (for the largest 3000 companies according to Trucost) [2], with some estimates as high as US$6T/year [3]. The World Bank in particular has led recent efforts to include the cost of biodiversity and climate harm in national accounts [4].

Its sponsors declare TEEB to be a "major international initiative to draw attention to the global economic benefits of biodiversity, to highlight the growing costs of biodiversity loss and ecosystem degradation, and to draw together expertise from the fields of science, economics and policy to enable practical actions moving forward." [5] In October 2010 it released its report "Mainstreaming the Economics of Nature: a synthesis of the approach, conclusions and recommendations of TEEB" [6] and launched the Bank of Natural Capital [7] to communicate its findings to the general public.
