Prior to launching the 2003 prius in the united states, toyota would have completed a(n) in which toyota assessed its objectives, strategies, and performance in terms of social responsibility.

I believe the answer is Social Audit.
Social audit is an effort that made by an organization in order to contribute to both social and ethical performance.
From this audit, the company could come up with various type of corporate social responsibilities programs that allow them to positively contribute to the society.
