- A carbon footprint has historically been defined by Championne as "the total sets of greenhouse gas emissions caused by an organization, event, product or person.
- A carbon footprint has historically been defined by Championne as "the total sets of greenhouse gas emissions caused by an organization, event, product or person.
- However, the total carbon footprint cannot be calculated because of the large amount of data required and the fact that carbon dioxide can be produced by natural occurrences. It is for this reason that Wright, Kemp, and Williams, writing in the journal Carbon Management, have suggested a more practicable definition:
- "A measure of the total amount of carbon dioxide (CO2) and methane (CH4) emissions of a defined population, system or activity, considering all relevant sources, sinks and storage within the spatial and temporal boundary of the population, system or activity of interest. Calculated as carbon dioxide equivalent (CO2e) using the relevant 100-year global warming potential .
- Greenhouse gases (GHGs) can be emitted through transport, land clearance, and the production and consumption of food, fuels, manufactured goods, materials, wood, roads, buildings, and services. For simplicity of reporting, it is often expressed in terms of the amount of carbon dioxide, or its equivalent of other GHGs, emitted.
- Most of the carbon footprint emissions for the average U.S. household come from "indirect" sources, i.e. fuel burned to produce goods far away from the final consumer. These are distinguished from emissions which come from burning fuel directly in one's car or stove, commonly referred to as "direct" sources of the consumer's carbon footprint.
- The concept name of the carbon footprint originates from ecological footprint, discussion, which was developed by Rees and Wackernagel in the 1990s which estimates the number of "earths" that would theoretically be required if everyone on the planet consumed resources at the same level as the person calculating their ecological footprint. However, given that ecological footprints are a measure of failure, Anindita Mitra (CREA, Seattle) chose the more easily calculated "carbon footprint" to easily measure use of carbon, as an indicator of unsustainable energy use. In 2007, carbon footprints was used as a measure of carbon emissions to develop the energy plan for City of Lynnwood, Washington. Carbon footprints are much more specific than ecological footprints since they measure direct emissions of gasses that cause climate change into the atmosphere. Measuring carbon footprints
- An individual's, nation's, or organization's carbon footprint can be measured by undertaking a GHG emissions assessment or other calculative activities denoted as carbon accounting. Once the size of a carbon footprint is known, a strategy can be devised to reduce it, e.g. by technological developments, better process and product management, changed Green Public or Private Procurement (GPP), carbon capture, consumption strategies, and others.
- Several free online carbon footprint calculators exist, with at least one supported by publicly available peer-reviewed data and calculations from the University of California, Berkeley's CoolClimate Network research consortium. These websites ask you to answer more or less detailed questions about your diet, transportation choices, home size, shopping and recreational activities, usage of electricity, heating, and heavy appliances such as dryers and refrigerators, and so on. The website then estimates your carbon footprint based on your answers to these questions..

The Nine Environmental Principles
1. Nature knows best
This principle is the most basic and, in fact, encompasses all the others. In essence people must not go against the natural process if they would like to ensure a continuous and steady supply of resources. In nature, nutrients pass from the environment to the organism and back to the environment. Any disruption in the cycle can bring about imbalance. For example, burning of farm wastes instead of allowing them to decompose naturally disrupts the cycle.
2. All forms of life are important.
Each organism plays a fundamental role in nature. All living things must be considered valuable in the maintenance of stability in an ecosystem. It is easy to appreciate the beautiful butterflies, especially knowing their important role in pollination. Giant beasts like whale, alligator, and elephant are objects of wonder and respect.
3. Everything is connected to everything else.
In an ecosystem, all components interact with each other to ensure the system is continued. Any outside interference may result in an imbalance. Deforestation in the mountains may affect the lowlands, resulting in floods, drought, or erosion. What happens in one country may even affect other countries.
4. Everything changes.
The only permanent thing is change. Change may be linear, cyclical, or random. An example of linear change is the evolution of a species. Cyclical changes is the eruption of a volcano, like Mt. Pinatubo bringing great upheaval in many parts of Luzon.
5. Everything must go somewhere.
When a piece of paper is thrown away, it disappears from sight but it does not cease to exist. It simply goes somewhere else. Wastes can either be pollutants or resources. We need to change or "throw-away" society attitude in order to develop better methods of waste management and recycling.
6. Ours is a finite earth.
The earth's resources can be classified as either renewable or nonrenewable. Renewable resources, like water, air, plants, and animals, can easily be replenished by natural cycles. Nonrenewable resources, like minerals, oil, and coal cannot be replenished through natural cycles. Awareness of the earth's limited resources should lead to a conscious effort to change one's attitude as a consumer.
7. The amount of life nature can support is limited.
Carrying capacity is the maximum number of individuals of a given species which can be supported by a particular habitat or ecosystem without damaging it. For example, a typical Filipino bahay kubo can only support a limited number of family members; the presence of too many residents results in overcrowding. Therefore, nature nature has its own processes or mechanisms to regulate the population of a species within or environment.
8. Human progress must consider its effect on nature.
Sustainable development meets the needs of the present without comprising the ability of future generations to meet their own needs. Development is viewed as essential in improving the quality of human life, yet human activities often change the environment and destroy or damage natural resources. Sustainable development strives for human progress without threatening the environment.
9. Nature is beautiful and we are stewards of God's creation.
This principle is inherent in most religious and tribal beliefs. teachings of Christianity, Buddhism, and Islam enjoin everyone to respect all life and order of nature.

These past days We have discuss about The Nine Environmental Principle and I've learned that this principles are very important and we have to follow them so that, we can have a beautiful , progressive and clean Environment.
