Simplification of Standards and Definitions
Carbon neutral fuels are those that neither contribute to nor reduce the amount of carbon into the atmosphere. Before an agency can certify an organization or individual as carbon neutral, it is important to specify whether indirect emissions are included in the Carbon Footprint calculation. Most Voluntary Carbon neutral certifiers such as Standard Carbon in the US, require both direct and indirect sources to be reduced and offset. As an example, for an organization to be certified carbon neutral by Standard Carbon, it must offset all direct and indirect emissions from travel by 1 lb CO2e per passenger mile, and all non-electricity direct emissions 100%. Indirect electrical purchases must be equalized either with offsets, or renewable energy purchase. This standard differs slightly from the widely used World Resource Institute and may be easier to calculate and apply.
The World Resource Institute, in addition to publishing many tables and help aids for calculating carbon footprints, only requires direct emissions to be reduced and balanced for carbon neutral status, however there is adequate encouragement to include all emissions sources. With this accounting, there are essentially two levels of Carbon neutral: Either all direct and indirect emissions, or only direct emissions.
Much of the confusion in carbon neutral standards can be attributed to the number of voluntary carbon standards which are available. For organizations looking at which carbon offsets to purchase, knowing which standards are robust, credible in permanent is vital in choosing the right carbon offsets and projects to get involved in. Some of the main standards in the voluntary market include; The Voluntary Carbon Standard, The Gold Standard and The California Climate Action Registry. In addition companies can purchase Certified Emission Reductions (CERs) which result from mitigated carbon emissions from UNFCCC approved projects for voluntary purposes. There are various resources available however to help companies navigate the often complex carbon offsetting standards maze.
The concept of shared resources also reduces the volume of carbon a particular organization has to offset, with all upstream and downstream emissions the responsibility of other organizations or individuals. If all organizations and individuals were involved then this would not result in any double accounting.
Regarding terminology in UK and Ireland, in December 2011 the Advertising Standards Authority (in an ASA decision which was upheld by its Independent Reviewer, Sir Hayden Phillips) controversially ruled that no manufactured product can be marketed as "zero carbon", because carbon was inevitably emitted during its manufacture. This decision was made in relation to a solar panel system whose embodied carbon was repaid during 1.2 years of use and it appears to mean that no buildings or manufactured products can legitimately be described as zero carbon in its jurisdiction.

Famous quotes containing the words standards and/or definitions:
“The things a man has to have are hope and confidence in himself against odds, and sometimes he needs somebody, his pal or his mother or his wife or God, to give him that confidence. He’s got to have some inner standards worth fighting for or there won’t be any way to bring him into conflict. And he must be ready to choose death before dishonor without making too much song and dance about it. That’s all there is to it.”
—Clark Gable (1901–1960)
“The loosening, for some people, of rigid role definitions for men and women has shown that dads can be great at calming babies—if they take the time and make the effort to learn how. It’s that time and effort that not only teaches the dad how to calm the babies, but also turns him into a parent, just as the time and effort the mother puts into the babies turns her into a parent.”
—Pamela Patrick Novotny (20th century)
