Dear Sarah,

here is a scale for children:

Children's Environmental Attitudes and Knowledge Scale (CHEAKS),

Thank you Béatrice. This scale seems more focused on attitudes. I was wondering if you know any scales that measure environmental behaviors ?

The idea is that the attitudes reflect our behaviors but this it not necessarily the case:

Mind the Gap: Why do people act environmentally and what are the barriers to pro-environmental behavior?

Abstract

Numerous theoretical frameworks have been developed to explain the gap between the possession of environmental knowledge and environmental awareness, and displaying pro-environmental behavior. Although many hundreds of studies have been undertaken, no definitive explanation has yet been found. Our article describes a few of the most influential and commonly used analytical frameworks: early US linear progression models; altruism, empathy and prosocial behavior models; and finally, sociological models. All of the models we discuss (and many of the ones we do not such as economic models, psychological models that look at behavior in general, social marketing models and that have become known as deliberative and inclusionary processes or procedures (DIPS)) have some validity in certain circumstances. This indicates that the question of what shapes pro-environmental behavior is such a complex one that it cannot be visualized through one single framework or diagram. We then analyze the factors that have been found to have some influence, positive or negative, on pro-environmental behavior such as demographic factors, external factors (e.g. institutional, economic, social and cultural) and internal factors (e.g. motivation, pro-environmental knowledge, awareness, values, attitudes, emotion, locus of control, responsibilities and priorities). Although we point out that developing a model that tries to incorporate all factors might neither be feasible nor useful, we feel that it can help illuminate this complex field. Accordingly, we propose our own model based on the work of Fliegenschnee and Schelakovsky (1998) who were influenced by Fietkau and Kessel (1981).

Exactly, it is not necessary that if an individual has environmental attitudes, that he would act upon that. That is why measuring attitudes may be very tricky. And I am trying to measure the real environmental behaviors and determine their factors.

Thank you for the reference, it is very interesting.  

NEP scale was used globally to measure environmental attitudes

My Handbook of Management Scales contains some scales related to environmental issues. Maybe check out whether one of them could be adapted: https://en.wikibooks.org/wiki/Handbook_of_Management_Scales
