These solvents often find their way into the water, soil and air resulting in significant pollution of the environment. Also known as sustainable chemistry or environmentally benign chemistry, green chemistry is a concept that is slowly being introduced at school level. Principle 5 prompts the consideration of auxiliary substances solvents, separation agents, drying agents etc. The removal of, or reduction in, chemical waste; the lowering of total energy requirements for chemical processes; and an increase in safety awareness are in the interests of humanity and the environment. As principle 9 indicates reagents used in catalytic amounts are preferable to reagents used in stoichiometric amounts. Synthetic methods should be conducted at ambient temperature and pressure. Principle 7 urges us to consider whether these starting materials can be derived from renewable resources. This necessitates the use of some energy source and most often this energy source is a fossil fuel. Here we will look at this from a climate chemistry perspective. Reducing waste One theme of green chemistry is how much of the reagents and solvents end up in the desired products, rather than as waste or by-products.

Measuring the efficiency of a reaction in this manner puts it into an entirely new perspective. Reducing the waste reduces the associated environmental problems. Most organic starting materials, such as the 1-butanol in Equation 1, are ultimately derived from crude oil, a nonrenewable depleting resource. Rather than consider the percentage yield and experimental atom economy separately, an even better indication of the efficiency of a reaction is to consider a combination of the two.
