Abstract:
All references to energy for pesticide production in agriculture can be traced
back to the original data of Green (1987). The most common method used to derive
values for current chemicals is to use the average of each category of active
ingredient. However a comparison of the mean and standard deviation of the
categories provides little justification for using anything other than the
overall average for agrochemicals, both for the total energy used and the
breakdown into the different sources of inherent and process energy. However it
is likely that using energy requirements derived directly from Green, such as
the mean or maximum will generally underestimate for chemicals introduced since
1985.
