Describe the Carbon taxing and carbon trading that aims to reduce the amount of carbon emissions.

A. Carbon taxing imposes a fee on companies based on the amount of carbon dioxide they emit, providing financial incentives to reduce emissions. Carbon trading allows companies to buy and sell permits to emit a certain amount of carbon, creating a market-based approach to reducing emissions.
B. Carbon taxing involves government regulations to limit the amount of carbon emissions from industries, while carbon trading allows companies to voluntarily offset their emissions by investing in carbon reduction projects.
C. Carbon taxing and carbon trading are two different approaches to addressing climate change, with carbon taxing focusing on penalizing polluters and carbon trading emphasizing market-based mechanisms for emission reduction.
D. Carbon taxing and carbon trading are ineffective methods for reducing carbon emissions, as they allow companies to continue polluting by simply paying for permits or taxes without making meaningful changes to their operations.
