USGBC Updated LEED-Green-Associate Exam Questions and Answers by ayub

Scope 1 greenhouse gas emissions are direct emissions from sources that are owned or controlled by the organization. On-site landfills are an example of a source of Scope 1 emissions, as they release methane and carbon dioxide from the decomposition of organic waste12.

Business travel, purchased electricity, and employee commuting are examples of sources of Scope 2 or Scope 3 emissions, which are indirect emissions from sources that are not owned or controlled by the organization. Business travel and employee commuting are Scope 3 emissions, as they occur from the activities of the organization’s value chain, such as suppliers and customers12. Purchased electricity is a Scope 2 emission, as it occurs from the generation of electricity that the organization consumes

According to LEED v4 BD+C LT Credit: Access to Quality Transit, determining whether a project has access to quality transit involves:

“Identifying the availability and frequency of existing and planned public transportation routes within walking distance of the project site.”

“Transit service must be at a defined level of frequency and include bus, rail, ferry, or other forms of public transportation.”

The key metric is the number of trips per day (both weekday and weekend) available at qualifying transit stops within a ¼- to ½-mile walk of the project. The credit assigns point values based on frequency and diversity of transit options—not parking or building design elements.

Option A (parking) relates to car use, which LEED aims to minimize.

Option B (surrounding density) supports sustainable location but does not directly measure transit access.

Option D (functional entries) relates more to walkability and building accessibility, not transit analysis.

Thus, Option C directly addresses the LEED intent for improving mobility and reducing vehicle dependence.

The triple bottom line is a business concept that states firms should commit to measuring their social and environmental impact—in addition to their financial performance—rather than solely focusing on generating profit, or the standard “bottom line”1. The triple bottom line can be broken down into “three P’s”: profit, people, and the planet2. Firms can use these categories to conceptualize their environmental responsibility and determine any negative social impacts to which they might be contributing1.

Native landscaping directly supports bothsite assessmentandoutdoor water use reductionby reducing irrigation needs and enhancing biodiversity:

“Install native or adaptive landscaping to reduce or eliminate irrigation demands… Site assessment is one of the most important parts of the integrative process…”

This synergy reflects environmental and water conservation priorities within the LEED rating system.
