As concerns rise over plans to pipe Canadian tar sands oil to the East Coast for the first time, a dormant effort to clean up the region's fuels is showing new signs of life.
The Northeast States for Coordinated Air Use Management (NESCAUM) has accelerated a project to crunch the full "life cycle" carbon emissions of vehicle fuels used in the region—from their extraction through to their refining, transportation and combustion.
With the fuel tracker, NESCAUM hopes to advance a clearer picture of the transport sector's sizable—and growing—contribution to regional greenhouse gas emissions.
The new data, expected to be released later this year, could be the underpinning of a climate policy several years in the works called the Clean Fuels Standard.
In 2009, NESCAUM, a nonprofit association of air quality agencies, began working with 11 states on the fuel standard, which could change the Northeast's transportation systems by requiring oil refiners and distributors to lower the amount of carbon in their fuels by up to 15 percent over 15 years. The program was to resemble the landmark low-carbon fuel regulations in place in California.
But last year, the states shelved formal work on the policy indefinitely due to a mix of political, economic and legal factors.
Now, a sense of urgency is once again building for action as industry plans several pipeline projects that could open a gateway for carbon-heavy oil sands to travel from western Canada to Eastern states.
Matt Solomon, transportation program manager for NESCAUM, said work on the fuel tracker kicked into gear last month, largely because of the "strong likelihood" that the region's fuel mix would soon get dirtier.
Currently, most of the petroleum that flows to the East Coast is light or medium crude oil; 11 percent is heavy oil mainly from Brazil, Cameroon and Venezuela.
About half of the total arrives as crude oil or refined products by ocean tanker, barge or railroad from more than a dozen countries and Midwest states. The rest is refined on the Gulf Coast and is transported mostly through a 5,500-mile pipeline that runs from Houston, Texas, to northern New Jersey, owned by Colonial Pipeline Company.
Solomon and others flagged three main pipeline proposals as potentially disruptive to the Northeast's fuel footprint:
►The Keystone XL pipeline. If approved by the Obama administration, the proposed 1,700–mile Keystone XL would transport oil from tar sands mines in Alberta to Texas for refining. Once refined, some of the Canadian heavy oil could reach the East Coast via the existing Texas-to-New Jersey pipeline. Colonial Pipeline spokesperson Steve Baker confirmed that possibility, but could not say whether plans have been made.
►TransCanada's East Coast route. TransCanada Corp., the Keystone XL's Canadian builder, could also supply tar sands oil to the Atlantic Coast by converting part of its cross-Canada natural gas pipeline to oil and expanding the line. The pipeline could link to the Irving Oil Corp. refinery in Saint John, New Brunswick, which currently supplies fuels to New England. "It's not a Plan B, it's a Plan A, and it will go if the market supports it," Russ Girling, the firm's CEO, told Bloomberg this month.
►Enbridge Line 9 reversal. Enbridge Inc., Canada's biggest pipeline operator, will begin to reverse the flow of its Line 9 pipeline this spring in order to move heavy Canadian crude further east—from Ontario to refineries in Toronto, and eventually to Montreal. Line 9 could potentially connect to another cross-border pipeline that, if reversed, would send tar sands oil from Montreal into Maine. The owner of that line, Portland Montreal Pipe Line Corp., has previously expressed interest in switching the flow to move Canada's oil to New England.
Oil Sands Among the Most Polluting
Calculating the full life cycle of emissions for each fuel is a crucial but "nightmarish accounting exercise," Solomon said.
California's Low-Carbon Fuel Standard uses a similar life cycle analysis to determine carbon intensity scores for 250 types of crude—about 60 of which are high carbon—plus alternatives like liquid biofuels, natural gas and electric cars.
The scheme, the first of its kind in the world, went into effect last year and requires the state's fuel mix to be 10 percent less carbon-intensive by 2020. Oil producers, importers and fuel blenders that exceed carbon intensity limits must reduce their scores by buying tradable credits or investing in cleaner alternatives.
The program ranks oil from the tar sands as among the most polluting of all fuels, with values of 106 to 111 grams of CO2 equivalent per mega joule, depending on where and how they're produced. Light crudes from Saudi Arabia, by comparison, score just under 94 grams, according to the California Air Resources Board, which enforces the mandate.
The European Union's preliminary Fuel Quality Directive gives oil sands crude an almost identical value. Both laws could discourage investment in Canada's heavy oil and other carbon-intensive sources of crude, clean fuel advocates say.
NESCAUM expects to complete the initial phase of its fuel calculator this year. It will continually update the tool as new or more accurate data become available, Solomon said.
