text: Criticism A number of organisations and individuals have criticised aspects of the 'Green Economy', particularly the mainstream conceptions of it based on using price mechanisms to protect nature, arguing that this will extend corporate control into new areas from forestry to water. Venezuelan professor Edgardo Lander says that the UNEP's report, Towards a Green Economy, while well-intentioned "ignores the fact that the capacity of existing political systems to establish regulations and restrictions to the free operation of the markets – even when a large majority of the population call for them – is seriously limited by the political and financial power of the corporations."
  Ulrich Hoffmann, in a paper for UNCTAD also says that the focus on Green Economy and "green growth" in particular, "based on an evolutionary (and often reductionist) approach will not be sufficient to cope with the complexities of [[climate
  change]]" and "may rather give much false hope and excuses to do nothing really fundamental that can bring about a U-turn of global greenhouse gas emissions. Clive Spash, an ecological economist, has criticised the use of economic growth to address environmental losses, and argued that the Green Economy, as advocated by the UN, is not a new approach at all and is actually a diversion from the real drivers of environmental crisis.  He has also criticised the UN's project on the economics of ecosystems and biodiversity (TEEB), and the basis for valuing ecosystems services in monetary terms.
