For PEAT’s Sake! Another Pathway Averting Climate Change

Posted on December 1, 2016 by Nicholas Robinson

After the smoke clears, damage still emerges from last spring’s wild and vast fires around Fort McMurray in Alberta. The NYT Science Times  (August 9, 2016) reported how fires like these are destroying Earth’s peat deposits, releasing volumes of greenhouse gases into the atmosphere.  Long-dead plant material in peat holds ancient carbon, which photosynthesis removed from the air. Worldwide, buried peat holds 30% of all carbon dioxide.

Most know peat only as dried “peat moss” used to enrich flowerbeds. Canada harvests 40,000 acres of peat moss, exporting 90% to the USA for gardeners. Peat is dried when mined. Exposed to the air, the peat oxidizes and its stored carbon is released. In Alberta, peat covers 65% of the oil sands. Cleared to permit surface mining, Alberta’s peat releases upwards of 47.3 million tons of stored carbon into the air. The wild fires ignited this exposed peat, and set peat in the ground ablaze. Fires are still smoldering, awaiting winter rains and snows.

Peat fires burn all around the world until rains extinguish them. Beyond billions of dollars in economic damage, natural systems are impaired. NASA provides an online observatory revealing the extent of these fires. This summer’s Siberian wild peat fires burn on.

Companies unlawfully burn peat in Indonesia to convert wet peat forests to palm oil and pulp plantations. Indonesia’s greenhouse gas emissions from burning peat are today equal to all the climate-changing emissions of China or the USA. Each year since 1997, the smoke from these fires causes air pollution locally in Riau and across the Straits of Malacca in Kuala Lumpur and Singapore.  Southeast Asia’s peat emissions are adding one gigaton of carbon dioxide a year. The Indonesian “Haze” is well documented, as in NASA’s 2014 recorded images.

Although peat deposits exist in all Earth’s regions, peat covers only 3% of the land surface. Peat has accumulated to depths of 30 feet or more. While drained or degraded peat areas are found today on 0.4% of the lands, these areas currently contribute 5% of total greenhouse gas emission. Their volume of emissions grows daily.

Mining of peat is an additional cause of the destruction of peat deposits and carbon emissions.  Peat is mined like coal in Ireland and in each Scandinavian country to fuel electricity generating plants. A new peat-fired power plant has opened in Uganda. The untapped peat in Central Africa is huge. Peat bogs in the Congo exceed the entire landmass of Great Britain. 

Some countries are taking steps to limit disturbance of peat deposits.  Finland, New Zealand and Great Britain are debating ending their exploitation of peat in order to help stop global warming.  Since 1989, Kew Botanical Garden in London has banned the use of peat, although the U.K.’s annual emissions  of carbon dioxide from mining peat for use in compost remain at 400,000 tons.  To stop air pollution of Moscow and halt ongoing greenhouse gases releases, Russia is re-wetting peat areas drained in the 1920s by the USSR. Russia’s protected wilderness areas hold the world’s largest preserved peat habitats.  Peat is protected in federal parks lands of Alaska.

Alternatives exist for every use of peat. Countries could legislate to ban peat sales and restore damaged peat deposits. States like New York or Massachusetts have already done so by adopting strict wetlands laws. The need to reduce greenhouse gas emissions provides a strong reason to ban sales of peat moss, and prohibit peat mining in Minnesota and nationally.  Emission-trading schemes can help finance transitions from peat abuse to peat preservation.

Peat preservation is critical. Paleoecologists mine peat for knowledge, learning how plants thrived and died over the 11,000 years since the last Ice Age. Peat reveals how climates change.  Accumulating slowly at 1 mm/year, peat is an irreplaceable record of life on Earth. Peat areas also host essential biodiversity.  Indonesia’s peat loss jeopardizes its Orangutan and Sumatran tiger habitat. In less than ten years, the Kampar Peninsula lost 43% of its peat, releasing 1.9 gigatons of greenhouse gases.  Indonesia has lost 18.5 million hectares of forests, an area twice the size of Ireland.

United Nations climate negotiators so far have ignored the plight of peat. At the 2015 Paris climate negotiations, Singapore stated that, “emissions of these fires by errant companies in Indonesia are more than the total CO2 emissions of Germany. This is comparable to the emissions of Japan.”  It is sobering to reflect that Southeast Asia’s peat emissions are matched by those in Canada and elsewhere.

This month, the World Conservation Congress of the International Union for the Conservation of Nature met in the USA for the first time. The 5,000 IUCN delegates in Hawai’i adopted a call for the worldwide protection of peat. Some efforts have begun. The United Kingdom is studying a “Peat Code” to finance peat restoration and preservation by payments to offset other gas emission. In Germany, “MoorFutures” are being offered in Bavaria for investors to finance peat offsets.

Much is at stake. If the climate warms and the peat is allowed to dry and burn across Africa, Asia, Siberia and elsewhere, run-away emissions can result. Aware of mounting environmental degradation, a year ago the nations in the UN General Assembly adopted a new Sustainable Development Goal, to “protect, restore and promote sustainable use of terrestrial ecosystems” by 2030.  For peat’s sake, let us get on with it.

FWS Goes Back to Square One On Listing the Wolverine. It’s Not Going to Be Any Easier This Time Around.

Posted on October 27, 2016 by Seth Jaffe

In April, Judge Dana Christensen vacated the Fish and Wildlife Service’s decision to withdraw its proposed listing of a distinct population segment of the North American wolverine WolverineSnowas threatened under the Endangered Species Act (“ESA”).  Bowing to the inevitable, the Fish and Wildlife Service ("FWS") has published in the Federal Register a formal acknowledgement that the Court’s vacatur of the withdrawal of the proposed listing returns the situation to the status quo.

In other words, the proposed rule that would have listed the wolverine distinct population segment ("DPS") is back in play.  Specifically, the FWS announced that

"we will be initiating an entirely new status review of the North American wolverine,hugh-jackman-wolverineto determine whether this DPS meets the definition of an endangered or threatened species under the Act, or whether the species is not warranted for listing.

FWS also reopened the comment period on the proposed listing and invited the public to provide comment, identifying nine specific areas in which it sought comments, including

"Information on the projected and reasonably likely impacts of climate change on the wolverine and its habitat, including the loss of snowpack and impacts to wolverine denning habitat.

This is all well and good and certainly required under Judge Christensen’s order, but neither Judge Christensen nor FWS has the tools necessary to address the core issue here, i.e., the unwieldy nature of the ESA.  It simply wasn’t designed to solve all of the ecological problems resulting from climate change.

It would be nice if Congress weren’t completely dysfunctional.

RGGI Is a Success Story. When Will It Be Obsolete?

Posted on September 29, 2016 by Seth Jaffe

When RGGI rggilogo2was first implemented, I heard Ian Bowles, then Secretary of Energy and Environmental Affairs in Massachusetts, say more than once that the purpose of RGGI wasn’t really to reduce greenhouse gas emissions or jump start the clean energy economy.  Instead, the goal was much more modest; it was simply to demonstrate that a trading regime could work.  The RGGI states were to serve as a model, to be the laboratory of a GHG allowance system.  The hope was certainly that RGGI would succeed its way into obsolescence.  Surely, by 2016, there would be a federal statutory basis for GHG regulation.

It’s now September 2016 and a federal statutory basis for a GHG trading system remains a seemingly distant hope (this post is definitely not about the Clean Power Plan).  We may still be waiting, but we do at least have substantial data from the laboratory that is RGGI.  In fact, yesterday, RGGI released its analysis of The Investment of RGGI Proceeds through 2014.  Some highlights:

  • Power sector GHG emissions have decreased by more than 45% since 2005, while regional GDP has increased by about 8%.
  • The total value of RGGI investments reached $1.37 billion through 2014.
  • Energy efficiency has taken up 58% of RGGI investment. The report states that the expected return is $3.62 billion in lifetime energy bill savings.
  • Clean and renewable energy make up 13% of investments, with an expected return of $836 million in lifetime energy bill savings.

One can quibble with these numbers.  They don’t really provide a reliable comparison to what would have happened in the absence of RGGI.  Nonetheless, it’s pretty clear that RGGI does work.  We can reduce GHG emissions without giving up on economic growth, and we can use the regulatory process to move our energy economy where it needs to be.

Now, if someone could just figure out a way to make RGGI obsolete, that would be true success.

ALL SPECIES MATTER

Posted on August 25, 2016 by Stephen Herrmann

GONE. The Bramble Cay melomys is no more.  The small rodent, the only mammal endemic to the Great Barrier Reef, is the first documented extinction of a mammal species due to contemporary climate change.  So says Luke Leung, a scientist from the University of Queensland.  “The key factor responsible for the death of the Bramble Cay melomys is almost certainly high tides and surging seawater, which has traveled across the island” destroying the animal's habitat and food source, said Dr. Leung.

Australia’s most isolated mammal had not been seen since 2007.  The report confirming the extinction of the Bramble Cay melomys, however, was not released until June 2016, in order to give scientists time to verify the loss of the species.  Upon release of the report, Dr. Leung said it was the first such extinction due to contemporary climate change.  He said his team “collected data, looked at other research and left no stone unturned” before making that assertion.  Dr. Anthony Barnosky, a professor at the University of California at Berkeley and a leading expert on climate change's effect on the natural world, said the claim seems “right on target to me”.

Both Drs. Leung and Barnosky believe that the climate change responsible for the demise of the melomys is caused by humans.  Whether caused by humans, aided and abetted by humans or merely not abated by humans, the extinction of the Bramble Cay melomys is, sadly, unlikely to be the last species loss to be caused by the effects of contemporary climate change.  How many more?

The Global Warming Solutions Act Requires MassDEP to Promulgate Declining Annual GHG Emissions Limits for Multiple Sources: Yikes!

Posted on May 23, 2016 by Seth Jaffe

On Tuesday, the Supreme Judicial Court of Massachusetts (SJC) ruled that MassDEP had violated the Global Warming Solutions Act progress-on-2020-planby failing

"To promulgate regulations that address multiple sources or categories of sources of greenhouse gas emissions, impose a limit on emissions that may be released, limit the aggregate emissions released from each group of regulated sources or categories of sources, set emissions limits for each year, and set limits that decline on an annual basis."

Phew.

The SJC gets the final word, so I won’t spend much time explaining why the SJC got it wrong, though I will note that to suggest that the legislature’s use of the phrase “desired level” of GHG emissions unambiguously requires MassDEP to establish hard targets was at best overenthusiastic.

The bigger question at this point is what the decision means.  First, it’s clear that MassDEP must establish hard declining emissions limits for more than one, but less than all, categories of GHG emitting sources.

Second, MassDEP must promulgate regulations that limit total emissions – not emission rates.

Third, the regulations must truly control Massachusetts sources.  The SJC specifically found that RGGI doesn’t satisfy the GWSA requirement, in part because Massachusetts sources can purchase allowances from out of state facilities.

But where does this leave MassDEP?  In a deep hole, for sure.  Unless it wants to ditch RGGI, it can’t regulate power generation, because the type of program that the SJC said is required would simply be incompatible with RGGI.

How about mobile sources?  They are the largest growing source of GHG emissions.  Unfortunately, we come back to the SJC’s injunction that MassDEP must regulate total emissions, not emission rates.  You tell me how MassDEP is going to issue regulations setting a cap on mobile source emissions.

The only obvious candidates I see are buildings and industrial sources other than power generation.

I don’t envy MassDEP – and the nature of the task only emphasizes the extent of the SJC’s overreach here – but I said I wouldn’t get into that.
