Sustainability and Ethics
Assignment 1
Student Name: Thabo Nkosi
Student Number: 56789012
Module Code: SUS1501
Unique Number: 654321
Due Date: 28 February 2026
, 1. Introduction
The concept of sustainability has evolved from a niche environmental concern to a
central organising principle for human civilisation in the twenty-first century. At its core,
sustainability asks a deceptively simple question: how can humanity meet its present
needs without compromising the ability of future generations to meet theirs? This
definition, drawn from the landmark Brundtland Report of 1987, remains the most
widely cited and foundational understanding of sustainable development.
This assignment introduces the foundational concepts of sustainability, explores the
three pillars of sustainable development — environmental, social, and economic —
and examines how these dimensions are interconnected. It further investigates the
historical development of sustainability as a global concept, the role of key
international agreements, and the relevance of sustainability to the South African
context. The assignment draws on prescribed module material and relevant academic
sources to provide a comprehensive overview of sustainability and its ethical
dimensions.
2. Defining Sustainability: Concepts and Origins
2.1 The Brundtland Definition and Its Significance
The World Commission on Environment and Development, chaired by Gro Harlem
Brundtland, published its seminal report Our Common Future in 1987. The report
defined sustainable development as "development that meets the needs of the present
without compromising the ability of future generations to meet their own needs." This
definition was revolutionary because it integrated environmental sustainability with
human development, recognising that poverty and ecological destruction are deeply
interlinked.
The Brundtland definition introduced two key concepts: the concept of needs,
particularly the essential needs of the world's poor; and the idea of limitations imposed
by the state of technology and social organisation on the environment's ability to meet
present and future needs. These concepts laid the groundwork for the three-pillar
model of sustainability that would become the dominant framework for policy and
practice worldwide.
