Carbon Neutral
Being carbon neutral, or having a zero carbon footprint,
refers to achieving net zero carbon emissions by balancing a
measured amount of carbon released with an equivalent amount
sequestered or offset. Best practice for organizations and
individuals seeking carbon neutral status entails reducing and/or
avoiding carbon emissions first so that only unavoidable emissions
are offset. The term has two common uses:
It can refer to the practice of balancing
carbon dioxide released into the atmosphere from burning fossil
fuels, with renewable energy that creates a similar amount of
useful energy, so that the carbon emissions are compensated, or
alternatively using only renewable energies that don't produce
any carbon dioxide (this last is called a post-carbon economy).
It is also used to describe the practice, criticized by some, of carbon offsetting, by paying others to remove or sequester 100% of the carbon dioxide emitted from the atmosphere, for example by planting trees, or by funding 'carbon projects' that should lead to the prevention of future greenhouse gas emissions, or by buying carbon credits to remove (or 'retire') them through carbon trading. These practices are often used in parallel, together with energy conservation measures to minimize energy use.
The concept may be extended to include other greenhouse gases
measured in terms of their carbon dioxide equivalence.
When an individual or an organization sets out
to become carbon neutral it is usually achieved by combining the
following three steps:
-
Limiting energy usage and emissions
-
Obtaining electricity and other energy from a renewable energy source, either directly by generating it or by selecting an approved green energy provider, and by using low-carbon alternative fuels such as sustainable biofuels.
-
Offsetting the remaining emissions that cannot for the moment be avoided or generated from renewables in a responsible carbon project, or by buying carbon credits.
Being carbon neutral is increasingly seen as good corporate or state
social responsibility and a growing list of corporations and states
are announcing dates for when they intend to become fully neutral.
To be considered carbon neutral, an organization must reduce its
carbon footprint to zero. Determining what to include in the carbon
footprint depends upon the organization and the standards they are
following.
Generally, direct emissions sources must be reduced and offset
completely, while indirect emissions from purchased electricity can
be reduced with renewable energy purchases.
Direct emissions include all pollution from
manufacturing, company owned vehicles and reimbursed travel,
livestock and any other source that is directly controlled by the
owner. Indirect emissions include all emissions that result from the
use or purchase of a product.
