Methodologically, we:
✔️ Extend Känzig (2023)’s EU ETS event dataset
✔️ Use surprises in carbon and critical metals futures
✔️ Identify shocks via Proxy-SVARs and sign restrictions
✔️ Run Structural Scenario Analyses
✔️ Validate using a structural DSGE

This tells us that 𝗰𝗹𝗶𝗺𝗮𝘁𝗲 𝗽𝗼𝗹𝗶𝗰𝘆 𝗳𝗼𝗿𝘄𝗮𝗿𝗱 𝗴𝘂𝗶𝗱𝗮𝗻𝗰𝗲
🏦 Can be an important policy tool
🌍 It affects macro outcomes and expectations
🌱 It can accelerate the transition

✅…without causing inflation

Path shocks affect climate-related expectations:
♻️ Investors rebalance toward greener assets
🛡️ Perceived climate risks fall
📉 Growth and consumption expectations fall
📈 Financial uncertainty rises

🏦 Monetary policy eases after a path shock.
✅ No trade-off, as inflation and output both fall.

In a structural counterfactual with no monetary easing,
➡️ emissions drop 3x more
➡️ output and prices drop 2x more

We back this up with an environmental DSGE model featuring:
🏭 green vs brown firms
💸 carbon taxes
🏦 monetary policy

The model reproduces the same inflation dynamics:
🔹 Stance shock = cost-push shock
🔹 Path shock = demand shock

Why is a path shock deflationary?
🔻 Households expect lower future income
➡️ reduce consumption today 🧺
📉 Aggregate demand falls more than supply
➡️ Inflation declines

Think of path shocks as 𝗳𝗼𝗿𝘄𝗮𝗿𝗱 𝗴𝘂𝗶𝗱𝗮𝗻𝗰𝗲 on climate policy.

🔹 Both shocks reduce emissions and output
🔹 But they have opposite effects on inflation:
  ⚠️ Current stance → inflationary (cost-push)
  🌱 Path shock → deflationary (demand-driven)

We exploit high-frequency surprises in carbon futures, critical minerals, and stock prices around announcements in the EU ETS

Our goal: disentangle
✅ “Current stance” shocks: changes in current carbon policy
✅ “Path” shocks: changes in future trajectory of carbon policy
