Negative externalities occur when the actions of individuals or businesses have harmful effects on others, for which they do not pay the full cost. This is known as Market Failure. In the context of environmental issues, negative externalities can arise from activities that contribute to pollution or climate change. One specific area where negative externalities are of concern is in the case of emissions. Emissions of greenhouse gases, such as carbon dioxide, contribute to climate change and have wide-ranging negative impacts. However, the costs associated with these emissions are often not fully borne by the emitters themselves, leading to a market failure.
To address this issue, there is a growing interest in Tracking and charging negative emissions with blockchain. Blockchain technology offers a transparent and secure way to track and verify emissions reductions or negative emissions. By using blockchain, it becomes possible to create a system where emitters are held accountable for their emissions and are required to pay for the negative externalities they generate. This approach has the potential to incentivize businesses and individuals to reduce their emissions and invest in technologies or practices that lead to negative emissions. By accurately tracking and charging for negative emissions, blockchain can help create a more sustainable and equitable system where the costs of emissions are properly internalized.
