Understanding the Basics of Carbon Pricing
Launch library · evergreen read
Carbon pricing puts a direct financial cost on emitting greenhouse gases, aiming to make the environmental cost of emissions, previously absorbed by the wider public and future generations, appear directly on the balance sheet of whoever is actually doing the emitting, rather than treating it as a cost borne entirely elsewhere.
The two most common approaches are a carbon tax, which sets a fixed price per tonne of emissions directly, and an emissions trading scheme, which sets a fixed total quantity of allowed emissions and lets the market determine the price through ongoing trading of a limited number of permits.
Both approaches share the same underlying economic logic: once emitting carries a genuine cost, businesses and individuals have a direct financial reason to reduce emissions where doing so is cheaper than paying the associated carbon price, encouraging investment in cleaner technology and processes over time as that price signal takes hold.
