Climate change is an example of market failure as there are no property rights to much of the environment and so there are no incentives to reduce pollution nor are there legal means to reduce contributions and thus the absence of property rights deepens the pollution problem. Market based solutions are policy instruments that use price and quantity controls to incentivise polluting firms to reduce and eliminate negative environmental externalities and reach the optimal level of pollution. Also due to the absence of a market there is also no market price with which to communicate preferences for environmental protection. In order to curb greenhouse gas emissions and mitigate climate change, there are widely thought to be four market-based solutions

A subsidy works as a negative tax and can be used to increase pollution abatement. Firms would receive a subsidy per unit of pollution abatement or as a lump sum in the form of a grant, loan or tax allowance which they would then spend of pollution abatement. If it is per unit of pollution reduction subsidy and is set at the same rate as a tax (MAC=MD) then the effects are symmetric and the graph would be the same as a tax (see Figure 1). The firm would reduce their level of pollution until the subsidy equalled their MAC and then would not reduce their pollution any further as they would have to lose money to do …show more content…
Under tradable permits, the government sets the level of pollution allowed per firm, and supplies the corresponding fixed level of permits available in the economy (S1). By introducing permits, the government has created an incentive for firms to reduce pollution, and if they are successful in reducing their pollution, firms can sell their extra permits to make a profit. Figure 3 shows the Market for Pollution Permits, when the government first introduces tradable permits (S1) the market demand is Q1 at a price of P1. Firms can decide to; (1) take the cost of reducing pollution, investing in green technology or increasing the efficiency of their factors of production, or (2) continue to pollute at the same level and buy permits at the market price. The firm will choose the option that will cost the least amount of
