A "kibocsátási kvóta" is a regulatory limit set by governments or international agreements on the amount of greenhouse gases that a company or country can emit over a specific period. These quotas are part of efforts to combat climate change by reducing overall emissions and encouraging sustainable practices. Companies that reduce their emissions below their allocated quota can sell their excess allowances to others that exceed their limits. This market-based approach, often associated with systems like the European Union Emissions Trading System, aims to create financial incentives for reducing pollution and promoting cleaner technologies.
