This chapter presents a range of viewpoints on the social responsibilities of the engineering profession. These social responsibilities of the engineering profession are in many ways synonymous with macroethics. Analysis of the engineering codes of ethics and educational requirements are used to support these arguments, and are compared with the perceptions of engineering students and working engineers. The social responsibilities of engineers include human safety and environmental protection in engineering designs. But it may extend further to include pro bono work and considerations of social justice issues. Research has found that perceptions of the professional social responsibilities of engineers vary across different countries/cultures, engineering disciplines (e.g., mechanical versus environmental engineers) and by gender. The impact of engineering education and broader college experiences on evolving notions of professional social responsibility will be described, in particular community engagement. Concerns about decreasing commitment to socially responsible engineering among college students, a so-called "culture of disengagement" will be presented, as well of the interaction of students' social goals for engineering and leaving engineering studies.
