## Assessment Instructions

<details>

<summary><strong>Intent</strong>: What is the purpose of this indicator?</summary>

This indicator assesses the actions the entity has taken to reduce waste production and optimize disposal methods across its portfolio. It captures the initiatives implemented over the past three years to enhance waste stream management across its assets.

</details>

<details>

<summary><strong>Input</strong>: How do I complete this indicator?</summary>

### Terminology

**Composting landscape and/or food waste**

> Composting is the controlled decomposition of organic material which produces useful soil amendment products. Engage in landscape and/or food waste composting either on-site or by contracting with a composting service provider.

**Ongoing waste performance monitoring**

> Track and measure ongoing waste volumes generated on a minimum quarterly basis, by either weight or volume, to help identify diversion and recycling opportunities within the organization. Conduct a minimum annual review to evaluate performance.

**Recycling**

> A program for materials that can be locally recycled and contracted with a recycling service provider. Provide appropriately sized recycling collection and storage areas within the entity’s real estate holdings to enable occupants to sort, collect and divert materials from landfill.

**Waste stream management**

> Hazardous and non-hazardous waste including reuse, recycling, composting, recovery, incineration, landfill, and on-site storage.

**Waste stream audit**

> A formal process used to quantify the type and amount of waste being generated, by weight or volume, to help identify effective waste reduction, separation and recycling opportunities.

**Measure**

> The actual project or activity undertaken/implemented to improve energy efficiency as part of the selected category.

## Frequently Asked Questions

<details>

<summary>Why can't I report efficiency measures that were implemented more than three years ago?</summary>

Although water efficiency initiatives implemented more than three years ago remain relevant, their impact is already accounted for in the consumption data reported under the Energy, GHG, Water, and Waste Aspects.

</details>

<details>

<summary>Can I report efficiency measures implemented during the construction stage?</summary>

Yes. For standing investments (operational assets), as long as the measures were implemented within the past three years (i.e., the reporting year and the two years prior), participants can report them, even if they were implemented during the construction phase.
