Keystone Climate Impact ‘Four Times’ Greater Than US Govt Estimate

Oil-Sand-Trucks-Athabasca-Shell_466Running from Canada to Texas, the future of the US$5.4 billion pipeline, which would carry oil from the Alberta tar sands, has become a key test of the White House’s “green” credentials.

Earlier this year the State Department declared Keystone’s possible environmental impacts to be negligible, carrying bitumen that would simply replace oil produced elsewhere.

But scientists from the Stockholm Environment Institute say this analysis did not take into account its affect on global markets.

While State calculated Keystone could lead to the release of 27 million tonnes of CO2e a year, Peter Erickson and Michael Lazarus argue the figure could be as high as 110 million.

In a supply and demand analysis, published in the journal Nature Climate Change, they say the pipeline’s full capacity of 830,000 barrels of oil a day could see international prices fall slightly and demand rise.

“The key message is that the oil market impacts of Keystone XL could be significant – and have an emissions impact four times greater than the US State Department found,” Erickson told RTCC.

“That also suggests that this type of analysis – analysing the possible market effects of other fossil fuel infrastructure projects – suggests that more analysis of those could be warranted, as they could have similar effects”.

The new findings are significant, given President Barack Obama’s pledge to only proceed provided it does not “significantly exacerbate” carbon pollution.

The pipeline has polarised opinion in the US, with the Canadian government and many Republicans broadly backing the project, which they say would create 6,500 jobs.

Critics say those investments would be better spent on clean energy, pointing to the fact that carbon-heavy tar sands are the source of some of the world’s dirtiest oil.

In March nearly 400 people taking part in ‘XL Dissent’ were arrested outside the White House, claiming its construction would run against President Obama’s high profile climate action plan.

In April the administration delayed a decision, which is now likely to be after the midterm elections in November.

Lazarus said it is still unclear why the State review, which was seized on by supporters of the pipeline as evidence it should be built, did not include a section on Keystone’s international impact.

“It’s not clear if this was an oversight or a limit in the scope of what they looked at in terms of global implications…so we’re not so much critiquing the study but saying there’s something missing here,” he said.

High cost fossil fuel projects are coming under increasing scrutiny ahead of a potential UN climate change agreement, scheduled to be signed in Paris next December.

Research by the Carbon Tracker NGO suggests many fossil fuel assets could become “stranded” if governments agree on policies to limit global warming.

These include multi-billion dollar investments in tar sands, the Arctic and other unconventional gas and oil exploration projects around the world.

Started in year 2010, ‘Climate Himalaya’ initiative has been working on Mountains and Climate linked issues in the Himalayan region of South Asia. In the last five years this knowledge sharing portal has become one of the important references for the governments, research institutions, civil society groups and international agencies, those have work and interest in the Himalayas. The Climate Himalaya team innovates on knowledge sharing, capacity building and climatic adaptation aspects in its focus countries like Bhutan, India, Nepal and Pakistan. Climate Himalaya’s thematic areas of work are mountain ecosystem, water, forest and livelihood. Read>>
