Nuclear power has been included as a separate footprint component in national Footprint calculations since Because it is difficult to calculate the extent of the nuclear demand on the biosphere, it was assumed that one unit of nuclear electricity had an equivalent Footprint to one unit of electricity produced with a world average mix of fossil fuels.
This change has been implemented in the edition of the National Footprint Accounts. The National Accounts Committee concluded that the emissions proxy approach for calculating the Footprint of nuclear electricity was not scientifically sound because:.
Actual carbon emissions associated with nuclear electricity are included in the National Footprint Accounts. However these emissions are only one among many environmental considerations relevant to nuclear power.
Therefore, for most nations, the effect of this methodological change on their results reported here will negligible. However, for countries with significant nuclear power supply such as Belgium, Finland, France, Japan, Sweden and Switzerland, the method change influenced their national Footprint values to a greater extent.
This exclusion of the nuclear Footprint component does not reflect a stance on nuclear energy. It simply acknowledges that only some aspects of nuclear energy are easily measured in terms of demand on regenerative capacity, the research question addressed by the Ecological Footprint.
However, the Living Planet Report—Japan for included an estimate for the biocapacity implications of the Fukushima accident. Jump to the Content FAQs. General What is the Ecological Footprint? What does the Ecological Footprint measure? Which Footprint calculator should I use? What is biocapacity? What is overshoot? How is an Ecological Footprint calculated? What is the proper way to use the term Ecological Footprint?
How does the Ecological Footprint relate to carrying capacity? What is the Water Footprint, and how is it related to the Ecological Footprint? What is an equivalence factor? What is a yield factor? When should I use the units global hectares, global hectare years, and global hectares per year? How does the Ecological Footprint address waste flows?
How does the Ecological Footprint account for recycling? What is a global hectare? Global hectares can also be converted into global acres. How accurate are Ecological Footprint measurements? How does Global Footprint Network address data quality? Are the Ecological Footprint calculations based on subjective judgment about the state of the world or the supposed need for environmental activism?
Are there any standards set for Ecological Footprint assessments? Is the Ecological Footprint the same as the carbon footprint? The carbon Footprint adds value to simple carbon emissions data in two ways: The carbon Footprint puts the magnitude of emissions into a meaningful context.
Many people do not know how to interpret 1, tonnes of carbon emissions, but they can easily understand that if 1, global hectares would be required to absorb this carbon, but only global hectares are available, this is a problem if we want to prevent this waste product from building up around us. The Ecological Footprint provides an overarching systems perspective that can reveal spill-over effects, when reducing demand in one area leads to an increase in demand elsewhere.
Would increasing the use of biomass fuels be more or less effective than returning cropland to forest cover? How does the Ecological Footprint treat water usage? What is the Water Footprint and how is it related to the Ecological Footprint? How does the Ecological Footprint account for pollution and toxic waste? We are using up many of our non-renewable resources such as copper, tin, coal and oil.
How does the Ecological Footprint measure this resource depletion? How does the Ecological Footprint relate to biodiversity?
Why is nuclear electricity no longer a separate Ecological Footprint component? The National Accounts Committee concluded that the emissions proxy approach for calculating the Footprint of nuclear electricity was not scientifically sound because: There is no scientific basis for assuming parity between the carbon footprint of fossil-fuel electricity and demands associated with nuclear electricity.
Biologically productive land and water can include arable land, pastures, and parts of the sea that contain marine life. The units for ecological footprint are global hectares gha , which measure the amount of biologically productive land with a productivity equal to the world average.
This land area is measured in terms of hectares, which each represent 10, square meters or 2. For some perspective, some ecological footprints of several countries are listed below. Note that ecological footprints can be counterbalanced by biocapacity , which refers to the ability of a biologically productive area to continuously generate renewable resources and clean up its wastes.
However, a carbon footprint measures the total amount of greenhouse gas emissions caused by an individual, organization, or activity. A carbon footprint is measured in units of carbon dioxide equivalents, which quantifies how much a certain amount of a greenhouse gas would impact global warming in reference to carbon dioxide. The carbon footprint thus concentrates on activities that would be related to greenhouse gas emissions, rather than considering an entire lifestyle as might be the case for calculating an ecological footprint.
A carbon footprint would be used, for example, to determine the impact that burning fossil fuels or consuming electricity would have on the environment. The ecological footprint considers many variables, and the calculations can become complicated. To calculate the ecological footprint of a nation, you would use the equation found in this research paper by Tiezzi et al. This equation compares the amount of goods consumed in a nation relative to how many of those goods were produced in the world, on average.
Equivalence factors, which differ depending on land use and year, help convert a specific land area into the appropriate number of global hectares. Yield factors take into account how different types of land can have smaller or larger impact on an ecological footprint calculation that factors in many types of products. The ecological footprint factors in the influence from many sources, but the calculation is very similar for each individual product.
After finding out the ecological footprint for every product, you would add all your answers to figure out the overall ecological footprint. Let's say you are growing carrots and corn on your farm and you want to figure out your farm's ecological footprint based solely on your crop production.
