; Policy Landmarks
: '''The 'Kyoto Protocol' (1997)''' → The "First Attempt": it only "Forced" rich countries to cut emissions, but it "Failed" because the **US** refused to join and **China** wasn't included.
: '''The 'Inflation Reduction Act' (USA, 2022)''' → The "Biggest Climate Bill" in history: it uses **$370 Billion** in "Subsidies" to "Build a Green Economy" rather than "Taxing the Old One."
: '''SBTi (Science Based Targets)''' → A system where **Corporations** (like 'Microsoft' or 'Apple') set "Net Zero" goals that are "Verified" by scientists, making "Climate Policy" a "Business Standard."
: '''CBAM (Carbon Border Adjustment)''' → A "Climate Tariff" by the **EU**: if you "Export dirty steel" to Europe, you "Pay a Tax" at the border. This "Forces" the **Whole World** to clean up.
