Global Warming and Externality: Case Switzerland

Global Warming is the increase of Earth's average surface temperature due to effect of greenhouse gases, such as carbon dioxide emissions from burning fossil fuels or from deforestation, which trap heat that would otherwise escape from Earth.
Burning of fossil fuels leads to an increase in global warming and hence leads to a negative effect on the environment.
Negative externalities are the negative effects on a third party by the actions of another party. In the case of global warming in Switzerland, the negative externality is on the citizens of Switzerland.
For example, the increase in use of fossil fuels would increase the amount of carbon dioxide gas in the air which would be inhaled by the citizens. This is the marginal social cost whereas the costs paid by the company that burns the fossil fuels is only paying their production costs that is the marginal private costs. Hence, the marginal social costs are more than the marginal private costs since the costs are more than what the company is paying for. In this case, the demand is constant and hence the marginal social benefit and the marginal private benefit is the same. From this, we can conclude that global warming is a negative externality.


What the government is doing to prevent this?
1.       Many governments have introduced cap and trade schemes
2.       In Switzerland, the FOEN handles the environment maintenance and pollution and hence they are the body that makes laws for polluting firms to pay carbon tax and to make them buy cap and trade schemes.
3.       The FOEN (Federal office for the Environment) which is the body related to the environment and maintaining it in Switzerland. In Switzerland, the FOEN has decided set laws that companies would have to buy cap and trade schemes. The principal of cap and trade schemes is to maintain the amount of carbon emissions in the atmosphere and to control the pollution by selling a limited amount of cap and trade schemes that allow a company to emit a certain amount of carbon dioxide into the air and this would help the government know how much carbon dioxide is being emitted and helps them to control it the FOEN has undertaken ETS in Switzerland. ETS (emission trading schemes)
4.       Companies that are large and intensive need to buy cap and trade schemes compulsorily whereas smaller companies may participate in this emission trading scheme voluntarily. The companies that have an installed capacity of 20MW are needed to participate in these schemes while companied that have an installed capacity of 10MW may participate voluntarily.
5.    The FEON predetermines the amount of emissions allowed per cap and they lower it every year. Emission allowance- emission allowances that are not emissioned for free are auctioned off for companies to buy and they are held several times a year.
6.       Monitoring by companies in the ETS- companies in the ETS must report their annual emissions. These emissions are recorded in a monitoring system. These reports may be verified by an independent third party by the FOEN.
7.    Emissions allowed for free(benchmark approach)(Only the quantity of emission allowances required for CO2-efficient operations are issued for free to companies participating in the emissions trading scheme (ETS). This quantity is calculated on the basis of benchmarks.
8.    In principle, the quantity of emission allowances issued for free is calculated based on product benchmarks. These benchmarks determine the maximum quantity of emission allowances that are issued per unit produced (e.g. 1,514 emission allowances per tonne of aluminium). Each benchmark corresponds to the average emissions of 10 per cent of the most efficient installations. In order to ensure the same competitive conditions [1]that exist in the EU, the Swiss ETS applies the same benchmarks as those used in the EU ETS.)


These are the steps undertaken by the Swizz government to prevent global warming from being a negative externality since they have tried to bring the marginal private costs and marginal social costs close since they increased the marginal private costs by making firms pay for the carbon emissions and this also lead to a decrease in the marginal social costs since this scheme reduces the carbon emissions since companies would not want to spend excess amounts on carbon taxes and would hence cut down on their carbon emissions.
