Green economics have so far been considered external to mainstream economics and there is a lot of discussion about whether they have any major points in similar. Green economics states that in the world we live in, needs looking after and if our daily transactions or dealings with each other affect the natural atmosphere, then it should be taken into account in decision making. As the natural resources are scarce, we can not use them wastefully, thus, our use of them should be noted.

Despite these derivations, there have been many individuals and economists who have criticized the neoclassical theories, especially when it came to the lack of attention given to the environment or the ecology. Green critics say that mainstream economists consider environmental and ecological considerations as externalities, which are a cost or benefit arising from an economic transaction or deal that affects a third party or people who are not directly related to the transaction. Conventional economics assume that the society's preferences are fixed and does not change or evolve with time or analysis.
The green economists have often also shown distrust about capitalism which refers to an economic system where ownership is in private hands and economic decisions are made by the market economy.
