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

Methane is a potent greenhouse gas that contributes to global warming and climate change. It is produced when organic waste decomposes anaerobically (without oxygen) in landfills1. Construction and demolition waste, which accounts for about a third of all solid waste generated in the world2, often contains a large amount of organic materials, such as wood, paper, and food waste1. Therefore, disposal of solid waste from building construction and operations in landfills has a substantial effect on methane emissions13. Incineration of solid waste also produces greenhouse gases, such as carbon dioxide, carbon monoxide, and hydrochloric acid, but at lower levels than landfilling45. Volatile organic compounds (VOCs) are not greenhouse gases, but they can react with other pollutants to form ozone, which is a greenhouse gas and a health hazard4.

Composting toilets operate without water, making them ideal for reducing potable water consumption. LEED promotes such innovative technologies for achieving water efficiency credits​​.

The Integrative Process is most effective during the early design stage of a project. This is when key decisions about the project are being made that can have a significant impact on its sustainability performance. By considering sustainability objectives from the outset, teams can identify opportunities for synergies and cost savings that may not be apparent later in the project. References: LEED Green Associate Candidate Handbook, U.S. Green Building Council resources

The Forest Stewardship Council (FSC) is a third-party verification organization that certifies forest products that are sourced from responsibly managed forests that meet environmental, social, and economic standards12. FSC-certified wood products are considered environmentally preferable products under the LEED v4 Materials and Resources category, as they reduce the negative impacts of deforestation, habitat loss, and biodiversity loss34.
