emissionsbaserade

Emissionsbaserade, also known as emissions-based trading or cap-and-trade, is an environmental policy mechanism designed to reduce greenhouse gas emissions by setting a limit on the total amount of emissions that can be emitted by a group of emitters, and allowing them to buy and sell emission allowances to meet that limit. The system is based on the principle of "polluter pays," where emitters are required to pay for the right to emit a certain amount of greenhouse gases.

The cap-and-trade system typically involves the following steps:

1. A cap is set on the total amount of greenhouse gas emissions that can be emitted by a group of emitters.

2. Emission allowances are created, representing the right to emit a certain amount of greenhouse gases.

3. Emitters are allocated a certain number of emission allowances based on their past emissions or other factors.

4. Emitters can buy and sell emission allowances on an open market.

5. Emitters must hold enough emission allowances to cover their emissions, and any excess allowances can be sold.

The cap-and-trade system is designed to create a market for emission allowances, which can drive down the cost of reducing emissions and incentivize emitters to adopt cleaner technologies. It is also designed to be flexible and adaptable, allowing for changes in the cap and the allocation of emission allowances over time.

Cap-and-trade systems have been implemented in various forms around the world, including the European Union Emissions Trading System (EU ETS) and the Regional Greenhouse Gas Initiative (RGGI) in the United States. The effectiveness of cap-and-trade systems in reducing greenhouse gas emissions is a subject of ongoing debate, with some studies suggesting that they can be an effective tool for reducing emissions, while others suggest that they may have limited effectiveness.
