Environmental economics is a subfield of economics that focuses on the economic impacts of environmental policies and the economic causes of environmental issues. It aims to balance economic growth with environmental sustainability by valuing natural resources and incorporating environmental costs into market decisions.
Marginal Abatement Cost (MAC) represents the cost of reducing an additional unit of pollution or emissions, serving as a critical tool for evaluating the cost-effectiveness of different environmental policies and technologies. Understanding MAC helps policymakers and businesses prioritize actions that yield the greatest environmental benefit for the lowest economic cost, facilitating optimal resource allocation in climate change mitigation strategies.
Pollution allowances, also known as emissions permits, are tradable certificates that allow a certain level of pollution emissions, typically used in cap-and-trade systems to control environmental pollution. They incentivize companies to reduce emissions by allowing them to sell excess allowances if they emit less than their allotted amount, thus creating a market-driven approach to environmental regulation.
Fossil fuel phase-out is the gradual reduction in the use of fossil fuels to mitigate climate change and promote sustainable energy sources. It involves transitioning to renewable energy, improving energy efficiency, and implementing policies that support decarbonization and reduce greenhouse gas emissions.
