The Obama administration on Tuesday outlined an ambitious plan for slashing U.S. greenhouse-gas pollution over the next decade, calling for accelerating the shift from fossil fuels to clean energy to stave off the worst effects of climate change.
Documents filed with the United Nations formally committed the United States to lowering total U.S. carbon emissions by 26 to 28 percent by 2025, compared with 2005 levels. White House officials called the plan “ambitious and achievable,” and said the pollution cuts could be made without hampering economic growth…
Stephen Harper’s government is reluctant to take action that burdens important sponsors who worry that even modest goals of reduction could result in critical injury. However, there is growing scientific skepticism about the accuracy of North America’s current greenhouse gas reporting. If emissions are proven to be substantially higher than claimed by government, citizens will demand comprehensive responses and that possibility worries powerful financial interests.
Forbes, a business magazine not given to climate change hysteria, reported on Natural Gas Leaks experienced by producers:
A new study released Tuesday suggests that the global oil and gas industries allow as much as 3.6 trillion cubic feet of natural gas — and almost certainly far more — to escape into the atmosphere annually. The leakage rate represents at least $30 billion in lost revenues, the analysis found, and it reinforces previous studies suggesting that the much-touted climate benefits of the expanding shale boom are unlikely to be realized unless these so-called fugitive emissions are brought under control.
While the chief component of natural gas, methane, breaks down in the atmosphere more quickly than carbon dioxide, it has far more planet-warming potential while it is present. The gas escapes from storage tanks and vents at oil production sites, and in even greater amounts all along the natural gas production and delivery chain — rising from wells, poorly constructed processing facilities, and leaky transmission and delivery pipelines. Over a 20-year time frame, the cumulative leakage in 2012, the new study suggested, would represent as much as 7 percent of total global greenhouse gas emissions — or the equivalent of about 40 percent of total carbon dioxide from coal-fired power production…
It is certain that Canada’s system of counting GHG emissions is thoroughly flawed. It depends almost entirely on self-reporting by industry and the federal government refuses to approve resources for effective oversight. It is an open secret among oil and gas producers that fugitive emissions are largely ignored. The following are extracted from Environment Canada reports:
How complete is Environment Canada’s report of GHG emissions? It is not worth much in BC nor is it accurate for the rest of Canada. In February, Vancouver Sun reporters Larry Pynn and Chad Skelton wrote The top 10 air polluters in B.C.. Excerpts:
…Industries are required to report data on some 300 pollutants where they meet the minimum threshold, [Francis Ries, a senior air-quality project engineer for Metro Vancouver] said, but the federal government lacks the staff to ensure accurate reporting.
…While pollution measurements from an industrial stack are relatively straightforward, the data does not account for “fugitive emissions” of which there can be plenty in the natural gas industry, both in pipelines and at processing plants, Ries noted.
“There’s not a lot of verification or oversight of the numbers,” he said.
…Ries noted that in 2012 industrial point sources represented about 44 per cent of the total human-generated emissions of the four pollutants analyzed by The Sun, transportation sources 41 per cent, and the remaining 15 per cent space heating, agriculture and other minor sources.
In terms of B.C.’s total greenhouse gas emissions of 61.5 million tonnes of carbon dioxide equivalent in 2012, transportation represented about 40 per cent, point sources 31 per cent and other categories 29 per cent.
“The point is that industrial point sources are not the only big sources of air pollution and greenhouse gases in B.C.,” Ries concluded.
BC Ferries is one example of unreported GHG emissions. A fuel usage report uncovered by The Tyee’s Andrew Macleod indicates the ferry company uses about 130 million litres of fuel annually. That suggests about 350,000 tonnes carbon dioxide equivalent, which would rank it in the top 10 of the province’s industrial GHG polluters.
