Cities, due to population concentrationhave large ecological footprints and have become ground zero for footprint reduction. This approach can also be applied to an activity such as the manufacturing of a product or driving of a car. This resource accounting is similar to life-cycle analysis wherein the consumption of energybiomass foodfiberbuilding materialwater and other resources are converted into a normalized measure of land area called global hectares gha.
The footprint can also be a useful tool to educate people about carrying capacity and overconsumptionwith the aim of altering personal behavior. Ecological footprints may be used to argue that many current lifestyles are not sustainable.
Such a global comparison also clearly shows the inequalities of resource use on this planet at the beginning of the twenty-first century. Inthe average biologically productive area per person worldwide was approximately 1. Methodology[ edit ] The ecological footprint accounting method at the national level is described on the web page of Global Footprint Network  or in greater detail in an academic paper.
While improvements are still possible, there are already standards available sincewith updates in Despite being populated by relatively "mainstream" home-buyers, BedZED was found to have a footprint of 3. The report did not measure the added footprint of the 15, visitors who have toured BedZED since its completion in Findhorn Ecovillagea rural intentional community in MorayScotlandhad a total footprint of 2.
However, the residents alone have a footprint of 2. However this should not be surprising, since the two methods address different research questions.
Newman has argued that the ecological footprint concept may have an anti-urban bias, as it does not consider the opportunities created by urban growth.
New York and Singapore respectively — may lead to the perception of these populations as "parasitic". This is because these communities have little intrinsic biocapacity, and instead must rely upon large hinterlands.
Critics argue that this is a dubious characterization since mechanized rural farmers in developed nations may easily consume more resources than urban inhabitants, due to transportation requirements and the unavailability of economies of scale.
Furthermore, such moral conclusions seem to be an argument for autarky. Some even take this train of thought a step further, claiming that the Footprint denies the benefits of trade.
Therefore, the critics argue that the Footprint can only be applied globally. For example, replacing ancient woodlands or tropical forests with monoculture forests or plantations may improve the ecological footprint.
Similarly, if organic farming yields were lower than those of conventional methods, this could result in the former being "penalized" with a larger ecological footprint. If the use of ecological footprints are complemented with other indicators, such as one for biodiversitythe problem might be solved.
A life cycle analysis centered on the Swedish Forsmark Nuclear Power Plant estimated carbon dioxide emissions at 3. The net result of the study was that nuclear power produced 3.
This compares to for natural gas and for coal according to this study. The study also concluded that nuclear power produced the smallest amount of CO2 of any of their electricity sources.
The World Nuclear Association provides a comparison of deaths due to accidents among different forms of energy production. In their comparison, deaths per TW-yr of electricity produced in UK and USA from to are quoted as for hydropower, for coal, 85 for natural gas, and 8 for nuclear.
List of countries by ecological footprint The world-average ecological footprint in was 2. There is also a high variation within countries, based on individual lifestyle and economic possibilities.With member countries, staff from more than countries, and offices in over locations, the World Bank Group is a unique global partnership: five institutions working for sustainable solutions that reduce poverty and build shared prosperity in developing countries.
The threats of climate change are real, but the solutions are now. An emission intensity (also carbon intensity, C.I.) is the emission rate of a given pollutant relative to the intensity of a specific activity, or an industrial production process; for example grams of carbon dioxide released per megajoule of energy produced, or the ratio of greenhouse gas emissions produced to gross domestic product (GDP).
Emission intensities are used to derive estimates of. In our definitive MXR Carbon Copy Review, we find out if it's really the best analog delay pedal out there.

Most of San Antonio’s global warming emissions are tied to energy use in buildings and from motor vehicles, according to the most thorough attempt to date at measuring the city’s carbon footprint.
