However, the business case, especially in terms of making a profit, is not as easily applicable in all areas of environmental protection and in the countries that need the most support.

One example of this is the need to better finance climate change adaptation efforts - as is discussed in Chapter 4, less than a fifth of climate-related development finance targeted climate change adaptation in 2013.
