I've found two valid sources for reference #4: "Spash, C. L. (2011) Terrible economics, ecosystems and banking. Environmental Values 20(2): 141-145."
These sources are the publisher's website of the free html version of said article, containing a link to a website providing the free pdf version for it as well[1] and the website itself hosting the free pdf version of the article given above.[2]
The website providing the pdf unfortunately doesn't offer a static link, which could just be copied and pasted into the source text of the criticism of TEEB section, but a dynamic link instead, which changes everytime you retreive the pdf document from the hosting website.
Furthermore, I would also like to suggest that in terms of consistency, the current given Format of reference #4:
"Spash, C. L. (2011) Terrible economics, ecosystems and banking. Environmental Values 20(2): 141-145."
corresponds to the formatting of reference #3:
"Spash, C.L. 2008. How much is that ecosystem in the window? The one with the bio-diverse trail. Environmental Values, vol. 17, no. 2, 259-284"
Thus the new formatting for reference #4 would result in:
"Spash, C. L. 2011. Terrible economics, ecosystems and banking. Environmental Values, vol. 20, no. 2, 141-145".
(I've tried to highlight the corresponding changes that I've made by writing in bold and italic combined.)
