What does the relationship between CO2 emissions and GDP, and why?
In general, richer countries will produce more CO2 per capita in comparison to poorer ones since richer countries observe higher levels of production and consumption.

Why do countries richer countries emit more than poorer countries?
Richer countries also have the means to create more effective environmental policies to project and manage their resources. The curved line of best fit on the Environmental Performance Index vs GDP per capita graph indicates that differences in income result in major EPI differences for poor countries but aren’t as major in richer countries.

Are there any policies that benefit both businesses and the environment?
Policies and measures that provide more monetary benefits than they consume in costs extend left of a vertical abatement cost curve; these policies are win-win. Upon implementing these policies, significant abatement would occur, and monetary benefits would be greater than costs.

What would the feasible frontier look like after considering win-win policies?
The feasible frontier would increase, and more consumption and abatement would be possible. The new frontier has a positively sloped part where environmental quality and consumption are increasing; after all win-win measures are introduced, costs begin to rise to achieve further abatement. Such potential oftentimes goes unrealized.

With these factors considered, what type of policies might be more effective?
These factors indicate that policies that ban harmful practices would be better than those that make them more expensive.

How can policies use the polluter pays principle?
Since the principle aims to dissuade negative environmental effects by making polluters pay for the consequences of their actions. the way a policy uses the polluter pays principle is through placing a tax on the polluting activity.

Is making the polluter pay the most efficient environmental policy approach?
In poorer countries, such a policy may seem unfair; if a lower-income family is still using wood fires to cook as opposed to electricity, causing more environmental effects, it would seem unfair to tax them as opposed to providing them with better resources. Using the same example, providing subsidies for more sustainable materials would be more cost-effective than tracking down and getting payments from thousands of entities.

EPI vs GDP per capita: graph tells us the relationship between a country’s wealth and its environment

The relationship between CO2 emissions and GDP is such that richer countries tend to produce more CO2 per capita compared to poorer countries. This is because wealthier nations have higher levels of production and consumption. Additionally, richer countries have the means to implement more effective environmental policies and manage their resources. There are policies that can benefit both businesses and the environment. These are policies and measures that generate more monetary benefits than the costs they incur. Such policies fall to the left of a vertical abatement cost curve and are considered win-win. Implementing these policies leads to significant abatement while ensuring that the monetary benefits outweigh the costs. Considering win-win policies, the feasible frontier would expand, allowing for increased consumption and abatement. The new frontier exhibits a positively sloped section where both environmental quality and consumption are increasing. However, costs begin to rise after all win-win measures are introduced, limiting further abatement. Unfortunately, this potential often remains unrealized. Given these factors, policies that outright ban harmful practices are generally more effective than policies that simply make them more expensive. By using the polluter pays principle, policies can discourage negative environmental effects by making polluters bear the costs of their actions. This principle is often applied through the imposition of taxes on polluting activities. While making the polluter pay can be an efficient environmental policy approach, it may seem unfair in poorer countries. For instance, taxing a lower-income family for using wood fires to cook instead of electricity, despite causing more environmental harm, may be perceived as unfair. In such cases, providing subsidies for more sustainable alternatives may be more cost-effective than tracking down and collecting payments from numerous entities.

Similar to how subsidizing more sustainable energy can improve the quality of life for lower-income citizens, some governments provide grants for higher education, also improving the quality of life for their lower-income citizens.
