Biodiversity Finance and Economics

updated May 2017

The cost of national action plans to achieve biodiversity targets agreed at the 2010 conference of the Convention on Biological Diversity (CBD) has been estimated at “between US$ 150 billion and US$ 440 billion per year.” by a UN High Level Panel. Targets for biodiversity finance required by the more recent 2015 Sustainable Development Goals will be even more demanding. Nonetheless, most scientists believe that the ultimate costs of not achieving these targets would be higher still.

As such financial goals are almost certainly out of reach, environmentalists press governments to take a more holistic view, addressing areas of expenditure which lead to destruction of biodiversity – such as inappropriate agriculture and fishing subsidies.

Whatever level of costing is deemed appropriate, the poorest countries will require assistance in funding their biodiversity plans. This topic is prominent in the biennial CBD conferences but the outcome is invariably similar to that for climate finance, with vague assurances that small amounts of aid funding can leverage large amounts of private sector engagement.

The richer countries, too, face the challenge of resourcing substantial price tags attached to their action plans. There is widespread interest in experimenting with financial mechanisms which aim to overcome the failure of contemporary economics to reflect the value of biodiversity in market prices.

A series of reports demonstrating possible economic tools has been published under the heading of The Economics of Ecosystems and Biodiversity (TEEB), a research initiative sponsored by the UN Environment Programme. By attributing monetary values to “ecosystem services”, the studies argue that decision-making by policymakers and businesses could be better informed; for example, by comparing the cost of restoring a damaged ecosystem with the economic benefit of a development.

The idea of “payments for ecosystem services” (PES) is well established. The best known example has evolved in climate change negotiations for tackling deforestation. Reducing Emissions through Deforestation and Forest Degradation (REDD) involves payments to forest communities in return for measurable conservation of the forest inventory. In practice, designing such schemes in low income countries is proving far more complicated than the basic principle implies.

The TEEB publications introduce ideas that go further than PES schemes, many under the banner of “innovative” private sector finance and “market mechanisms” for biodiversity. A 2013 UK government publication, described as a “best practice guide”, states that “examples of market-based mechanisms include trading systems in which irreversible damage (to biodiversity) in one place is compensated for through improvements elsewhere (eg biodiversity offsetting).” The European Commission has also conducted a consultation on biodiversity offsetting.

Many environmentalists question the scientific basis of offsetting. Critics of market mechanisms anticipate the biodiversity equivalent of carbon trading which has a chequered history in raising climate finance. And they  object in principle to putting a price on functions in nature which are critical to human life, observing that it is impossible to calculate the cost of restoring an extinct species or an ecosystem which has totally collapsed.

If the economics of biodiversity fails at the extremes, then there may be no choice but to respect a combination of science and the precautionary principle in our search for sustainable development.
