WHAT — PREVENTION AND POLICY SLOGANS — RULES
AQI alerts. Ban on CFCs. Emission standards as a phrase. If the NBF book names a Pakistan act, use that name only — do not invent law. 3R: reduce, reuse, recycle — applied to waste and energy. This page separates the idea from the wider topic “PREVENTION AND POLICY SLOGANS” so it can be revised and assessed on its own.
WHY — Why this topic matters
PREVENTION AND POLICY SLOGANS — RULES is an independent FBISE learning unit because students must use its definitions, conditions, equations, or trends separately in explanations and calculations.
HOW — How it works
AQI alerts. Ban on CFCs. Emission standards as a phrase. If the NBF book names a Pakistan act, use that name only — do not invent law. 3R: reduce, reuse, recycle — applied to waste and energy. Examples: Montreal named; AQI named; No scrubber blueprint. Exam use: Exam prevention list: less fossil burn, converters named, low-S fuel, CFC bans (Montreal named), AQI slogans — not how to emit.
