Sustainability and Ethics in Engineering Notes

Sustainability and Ethics in Engineering

Introduction to Sustainability

  • Definition: Sustainability refers to meeting human needs and wants without exhausting productive resources (Mensah, 2019).

  • Three Pillars of Sustainability:

    • Social: Community, education, equity, health, well-being.

    • Environmental: Management of natural resources, air and water quality, energy conservation.

    • Economic: Focus on the bottom line, cash flow, and profitability (Purvis et al., 2018).

The Tragedy of the Commons

  • Overview: A situation where shared resources are overused and depleted because individuals act according to their own self-interest rather than considering the common good.

  • Relevance to Engineers:

    • Engineers often work in environments where they face these issues, impacting wider industries.

    • It is crucial to find collective solutions to ensure sustainable practices.

Planned Obsolescence

  • Definition: The design of products with a limited useful life, leading consumers to frequently replace them.

  • Impacts:

    • Creates artificial consumer demand and revenue for companies.

    • Results in increased environmental waste as multiple disposable goods are produced instead of long-lasting alternatives.

Unsustainable Technology

  • Challenges: Short-term benefits for firms using traditional, unsustainable technologies can lead to long-term environmental damage.

  • Incentives for Change: Without collective agreement among firms to adopt new technologies, individual firms may resist innovation due to perceived risks.

Economic Considerations in Sustainability

  • Funding Challenges: Developing sustainable technology often requires significant upfront costs and long-term investment without immediate profitability.

  • Collective Financial Responsibility: A need for a shared burden among firms to advance sustainable technologies.

Role of Engineers

As Citizens
  • Advocacy: Engineers can lobby for government action and policy changes that support sustainability.

  • Individual Actions: Encouraging reduced consumption at the personal level contributes to a more sustainable society.

As Engineers
  • Collaboration: Engineering bodies can coordinate and establish sustainable standards, making it easier for all companies to adopt changes simultaneously.

  • Technology Development: Engineers can drive innovation in sustainable technologies (e.g., electric cars, renewable energy).

  • Education: There is a need to educate consumers on repairing and maintaining products instead of replacing them.

Types of Solutions

Technical Solutions
  • Advantages:

    • Do not necessitate behavior changes from individuals.

  • Disadvantages:

    • Do not alter consumption patterns or attitudes.

    • Ambiguity regarding cost responsibilities.

Social Solutions
  • Advantages:

    • Impact consumption habits and environmental attitudes.

  • Disadvantages:

    • Require people to change their behaviors and necessitate coordination or force.

Integrated Approaches

  • Need for Dual Solutions: Addressing the tragedy of the commons cannot solely rely on technological advancements but also requires changes in social behavior and collective commitments.

Case Study: Google’s Project Ara

  • Overview of the project, aiming to develop a modular phone that promotes repair over replacement.

  • Challenges Faced: Issues of commercial viability and the eventual halt of project development led to the technology being sold to third parties.

Meeting Preparation (Hypothetical Scenario)

  • As an engineer at Google, consider the potential impact of continuing or halting the project.

  • Arguments for Continuing:

    • Essential for sustainable technology advancement.

  • Arguments Against Continuing:

    • Business focus on profit and viability for shareholders.

UN Sustainability Goals

  • Sustainable development aims to meet present needs without compromising future generations.

  • Five P's of Sustainable Development:

    1. People: End poverty, promote well-being.

    2. Planet: Protect natural resources and combat climate change.

    3. Prosperity: Ensure economic growth and fulfilling lives.

    4. Peace: Foster inclusive, peaceful societies.

    5. Partnership: Mobilize support for sustainable development globally.

Conclusion

  • Engineers hold a vital responsibility in advocating for and implementing sustainable practices.

  • Both technical innovations and social behavior changes are essential to address sustainability challenges effectively.
