Climate Economics

This guide helps you get your bearings in Climate Economics before you start exploring the interactive timeline, framework graph, and concept maps.

Before You Dive In

Climate Economics studies environmental externalities and policy design for sustainability under uncertainty.
Rough timeline: Pigouvian taxation and welfare analysis -> resource and conservation economics -> climate integrated assessment -> transition and adaptation policy design.
Start with externalities and property-rights logic before moving to climate-risk dynamics.
Use Noosaga to compare frameworks by instrument: carbon pricing, standards, permits, subsidies, or hybrid approaches.

ExternalityCost or benefit imposed on others outside market transactions.

Pigouvian taxCorrective tax set to align private and social marginal costs.

Cap-and-tradeQuantity-based policy that sets an emissions cap and allows permit trading.

Social cost of carbonMonetized damage from emitting one additional unit of carbon.

Discount rateParameter that weights future climate damages relative to present costs.

Treating carbon pricing as sufficient without complementary innovation and distribution policy.

Assuming valuation uncertainty implies inaction.

Confusing short-run compliance costs with long-run transition gains.

Open the interactive view and scan the framework timeline. Which frameworks came first? Which ones overlap? Where are the big transitions?

Click into individual frameworks to read what each one claims, where it came from, and how it relates to its neighbors.

See how the key ideas within a framework connect. This is useful for figuring out what to learn first and what depends on what.

Take the quiz for any framework you've read about. It's a quick way to find out whether you actually understood the core ideas or just skimmed them.
