A carbon-neutral product is one in which the emissions of carbon
dioxide during production are balanced by reductions or the purchase of
credits known as offsets that result in a net environmental benefit.
The concept is popular in many industries, including the construction
sector, and British Columbia legislators have demanded that the
province’s public service be carbon neutral by 2010.

Reinhold Krahn of SunSelect says that the family-run greenhouse
invested “many millions” of dollars to install wood boilers and energy
screens at its 70 acres of tomato and pepper greenhouses in the Lower
Mainland to generate the so-called “carbon credits” that helped it
produce carbon-neutral peppers. The project won SunSelect an award from
the British Columbia Innovative Clean Energy Fund in 2008.


BURNING WOOD WASTE IS CARBON NEUTRAL

Since burning wood waste releases no more carbon dioxide than wood does
when it decomposes naturally, it’s considered a neutral alternative to
burning natural gas. The practice garners credits – each one
representing the removal of 1,000 kilograms of carbon dioxide from the
atmosphere – for SunSelect in consequence.

“By using the energy from wood, you’re not adding any more carbon
dioxide to the environment, and so that’s where the reduction in carbon
dioxide emissions arises,” Krahn explained. “The difference in carbon
emitted is used to calculate your reduction in carbon emissions.”

SunSelect isn’t carbon neutral itself, however.

While it originally used its credits to offset carbon dioxide emissions
from its pepper shipments, Krahn said the bigger return has been from
selling the credits to other businesses through Vancouver-based
Offsetters Carbon Neutral Society. Offsetters pays credit suppliers
between $8 and $15 a credit, depending on the investment made to secure
carbon reductions.

Offsetters verifies the reduction of emissions at SunSelect on an
annual basis and handles the sale of any excess credits the greenhouse
generates. SunSelect’s agreement with Offsetters prevents Krahn from
disclosing how much he gets from the sale of offset credits, but he
indicates that the amount was significant enough to make the transition
to woodboilers worthwhile.

“The carbon credit program provided basically a source of funding to
allow us to defer some of the capital costs to get there,” he said.
“That’s why we participated in it.”


VOLUNTARY OFFSETS MARKET WILL TOTAL $250M IN 2012

Offsetters president and co-founder James Tansey expects the voluntary
market for offsets to total $250 million in 2012. But he told growers
attending the Pacific Agriculture Show in Abbotsford, B.C., earlier
this year that going carbon neutral can also create a marketing
opportunity.

“There’s brand equity value in doing these kinds of things,” Tansey
said, noting that Vancouver-based Harbour Air introduced a 50-cent a
ticket charge to offset flights and become a carbon-neutral air carrier
– and saw ridership rise 12 per cent.

The structures are also coming into place to ensure carbon-neutral
initiatives are genuine. British Columbia’s Pacific Carbon Trust will
issue credits only for projects launched after Nov. 27, 2008, although
older contracts for purchasing credits may be eligible for
participation in the trust if they expressly mention future projects.

Tansey claims that offsets are often more efficient for an operation
than making internal changes in how it does business. “It’s a more
economically efficient way of getting to carbon neutrality than by
doing it yourself,” he said.

This is partly why SunSelect, when it examined its business, chose to
sell its carbon credits to other companies rather than offset the minor
amount of emissions its pepper shipments were generating. The
environmental benefits of doing what it could to offset what another
company might be doing were greater, while generating proceeds that
offset the cost of its own carbon reductions.


WESTERN CLIMATE INITIATIVE EXPECTED TO BE IN PLACE BY 2012

Emily Blair, coordinator of the B.C. Agrifood Climate Action Initiative
that’s developing a plan for B.C.’s agriculture industry to participate
in the market for carbon offsets, said the province is aiming to cut
greenhouse gas emissions by 33 per cent from 2007 levels by 2020. The
government-owned Pacific Carbon Trust will administer carbon credits
prior to the Western Climate Initiative
(www.westernclimateinitiative.org) coming into effect (expected by
2012). The initiative includes B.C., Ontario and Québec, as well as
seven U.S. states, and will create an international market for the
exchange of carbon credits.

Projects considered for offset credits have to go beyond existing best practices to generate offsets.

“They have to be beyond business-as-usual and reduce greenhouse gas
emissions,” Blair said of the projects. “I think this is a good system
for the greenhouse sector.”
