Value-Action Gap

  • Definition: The gap between values (what we say we care about) and actions (what we actually do). The speaker identifies a value-action gap when there is a mismatch between stated values and everyday behaviors.

  • Example sequence illustrating the gap:

    • I compost.

    • I ride my bike to work.

    • I also have a car that I take skiing every weekday.

    • I have a cell phone that I feel is destroying my mind.

  • Personal conflict example: I love skiing; do I love skiing more than the environment? If asked, I’d say no, but actions (e.g., car use for skiing) suggest otherwise.

  • Core question: What structures impede acting in accordance with life-supporting values? The social sustainability piece is tricky to measure and understand.

  • Research direction: Dan and the speaker are developing a framework to understand why the values-action gap exists and what factors drive people to act in ways that don’t align with their stated values.

  • Social sustainability focus: Emphasizes the social piece that makes alignment difficult; not just individual choices but the social and institutional context.

  • Practical implication: Understanding this gap helps in designing policy, institutions, and interventions that align values with actions.

Sustainable Development Goals (SDGs)

  • There are 1717 Sustainable Development Goals.

  • Origin: Outcomes of conversations at multilateral conferences; developed by the United Nations Environmental Programme (UNEP).

  • Course relevance: SDGs will play a key role in the semester and appear on both the midterm and final, but students are not required to memorize all goals.

  • Structure and timeframe: SDGs provide a 15-year snapshot to track progress and compare across years; goals themselves are not updated frequently in the presentation context.

    • Question about updates: A student asks whether new goals could be added in the future (e.g., by 2027). The instructor explains that the structure provides a 15-year snapshot to compare years, implying that the goals themselves are not regularly added; however, the instructor also hints there may be data updates and that this remains a nuanced question.

  • Examples of goals and scope:

    • Life on Land (SDG 15) and biodiversity are highlighted as key areas within the broader SDG framework.

    • Biodiversity and ecosystems are framed as significant components within the
