This report delves into the interconnected concepts of sustainable marketing, green marketing, and ethical consumerism. It begins by defining sustainable marketing as a practice that meets current needs without compromising future generations' ability to meet their own, and then examines green marketing as a subset of sustainable marketing, emphasizing environmentally beneficial products and sustainable manufacturing processes. The report explores ethical considerations within sustainable marketing, focusing on the relationship between products and their surroundings, and the integration of socio-ecological marketing. Examples of sustainable marketing, such as Toyota's Prius and Volkswagen's 'clean diesel' vehicles, are provided. The report also details the elements of green marketing, including a balanced approach to social and technological aspects, qualitative product development, and a focus on genuine consumer needs. Issues in green marketing, such as the need for standardization, the relative newness of the concept, and its potential challenges in meeting customer satisfaction criteria, are addressed. The report then defines ethical consumerism as consumer activism based on 'dollar voting' and explores its issues, such as limited consumer impact on manufacturing and potential market monopolies. The report concludes with a case study of Wesfarmers' green marketing practices and includes references to relevant academic literature.
