When selecting a SHS agent with environmental concerns, which factors should be considered?

• A. Global warming potential
• B. Ozone depletion potential
• C. Regulatory restrictions
• D. All of the above

Answer: (D)

When choosing a SHS agent with environmental concerns, you evaluate how the agent affects the environment now and in the future, plus how rules apply to it. Global warming potential measures the agent’s climate impact relative to CO2 over a specific time horizon; a lower GWP means less contribution to warming. Ozone depletion potential shows how likely the agent is to harm the stratospheric ozone layer; a lower or zero ODP is preferable for protecting the ozone. Regulatory restrictions reflect current and upcoming laws, bans, or phaseouts that could affect availability and compliance. Because each of these factors addresses a different aspect of environmental impact and regulatory risk, you consider all of them together to make a responsible choice. In practice, you’d aim for low GWP, no or minimal ODP, and favorable regulatory status, recognizing that one factor alone could be misleading if regulations change or alternatives differ in climate impact.
