A public good is non-excludable and non-rivalrous (everyone can use it, and use doesn't reduce availability, e.g., national defense, street lighting). A common good (or common-pool resource) is non-excludable but rivalrous (anyone can use it, but use reduces availability, e.g., fishing grounds, forests). Both are accessible to all, but only common goods suffer from depletion.
In other words, public goods are “ non-rivalrous,” but common goods are “rivalrous.” Because of these features, the consumption of common goods by one person reduces one or more other person's ability to consume the same good.
Remember, common goods are not like public goods such as national defense or public sanitation. The national defense can't generally be used up (unless of course the country is invaded). But, like a public good, common goods are non-excludable.
Examples of particular common goods or parts of the common good include an accessible and affordable public health care system, an effective system of public safety and security, peace among the nations of the world, a just legal and political system, an unpolluted natural environment, and a flourishing economic system ...
The government plays a significant role in providing goods such as national defence, infrastructure, education, security, and fire and environmental protection almost everywhere. These goods are often referred to as “public goods”.
In economics, a public good (also referred to as a social good or collective good) is a commodity, product or service that is both non-excludable and non-rivalrous and which is typically provided by a government and paid for through taxation.
For a good to be a public good, it must be nonexcludable and nonrival. So, for example, public transportation is not a public good. It is excludable, because the transit company won't give you a ride if you don't pay the fare. It's also rival because public transportation has limits.
In philosophy, economics, and political science, the common good (also commonwealth, common weal, general welfare, or public benefit) is either what is shared and beneficial for all or most members of a given community, or alternatively, what is achieved by citizenship, collective action, and active participation in ...
Cars are considered private goods because they are excludable (only those who own or have access to a car can use it) and rivalrous (one person's use of a car prevents another from using it).
The common good is reached when we work together to improve the wellbeing of people in our society and the wider world. In line with Catholic Social Teaching, the rights of the individual to personal possessions and community resources must be balanced with the needs of the disadvantaged and dispossessed.
What are the two main characteristics of a public good?
A public good has two key characteristics: it is nonexcludable and nonrivalrous. These characteristics make it difficult for market producers to sell the good to individual consumers. Nonexcludable means that it is costly or impossible for one user to exclude others from using a good.
When businesses engage with the common good, they are assuming a broader engagement with society through the integration of moral codes into their operations. The commons problem requires a focus on sustainable management and community-based organizing to ensure that shared resources are used equitably and responsibly.
The “common good” is deontological and focuses on the fairness of the rules and processes themselves, not just the end results. “Common good” decisions or actions benefit all or most members of a community, often through shared resources or services.
Five examples of public goods are: national defense, street lighting, clean air, public parks, and basic scientific research. These goods are non-excludable and non-rivalrous, meaning everyone can benefit from them without reducing their availability to others.
Thus, a lighthouse's service is also non-rival. Another example of a public good is the air we breathe. People can't be stopped from using air, nor does breathing limit someone else's ability to breathe. Yet more examples of public goods are disease prevention and national defense.

What is the difference between a public good and a common good?
If a good is both non-rival, and non-excludable it is a Public Good. If it is both rival and excludable, it is a Private Good. If a good is rival, but non-excludable it is a Common Pool. If a good is non-rival but excludable it is a Club Good.
To be classified as a public good, the product or service must remain non-excludable and non-rivalrous. The types of public goods include security, education, knowledge, infrastructure, environment and health.
A public good is any product or service that is available to all residents of a society, such as national defense, police and fire services, clean air, and drinking water.
