The Patrick Administration recently released new rules on biomass energy that will do more to protect critical forest resources. Photo credit: Lizard10979 @ flickr.

Last week, the Patrick Administration released new proposed final rules and guidance on the state’s incentives for biomass energy. It is a big win for our forests, for the role of science in policy making, for efficiency, and for environmental advocates across Massachusetts. I’m proud of the Patrick administration for their tireless work on this issue.

So, what exactly IS biomass? Generally speaking, in the energy context, “biomass” refers to a class of fuels derived from trees and plants. Other types of biomass fuel are organic wastes such as livestock manure, spoiled food, and even sewage. These fuels are, in turn, converted into various forms of useful energy (electricity, heat, transportation fuels) by a very broad spectrum of established and emerging technologies.

When we hear about biomass energy, most often the focus is on large electric power plants. There are many such biomass power plant proposals pending throughout New England, including several in Massachusetts. We hear about them in the news, but rarely is there much talk about why so many biomass power plants are in the permitting pipeline right now. Although not often noted, the reality is that these projects are responding to state and federal economic incentives.

One might assume that state and federal biomass incentives are specifically designed to promote projects consistent with our clean energy and climate objectives, right? Unfortunately, that has not been the case.

Understanding of the substantial potential climate and environmental impacts of biomass power plants has lagged behind the incentive programs. When the incentive programs were created, no one was focused on the potential climate impacts of building power plants that burn whole trees to produce electricity, for example. The thinking was that if a tree were used as fuel, it simply needed to be replaced with a newly planted tree and – voila! – some of our energy needs would be met with a “renewable” fuel.

To the contrary, as we now understand, burning whole trees as fuel results in a climate “double whammy”:

1. Instantaneously releasing all the carbon stored in each tree into the atmosphere; while also
2. Taking whole trees out of commission as carbon “sinks,” no longer capturing and storing new carbon emissions.

Thankfully, the last few years have provided a huge wake-up call. We’ve seen an increasing body of peer-reviewed science about the potential climate impacts of irresponsible use of biomass energy. The forward-looking Patrick Administration itself commissioned a groundbreaking study, culminating in the 2010 “Manomet Report,” to bring that science home to Massachusetts in the context of a hard look at better-designed state incentives for biomass. And now, just last week, the Patrick Administration released new proposed final rules and guidance that infuse this science into the state’s biomass incentives. You can read a copy of CLF’s official statement here.

From a preliminary review, we are delighted to see that the newly proposed Massachusetts rules embrace the three key pillars of responsible policy governing biomass incentives:

1. Adopting science-based standards to seriously account for the climate impacts of eligible biomass facilities and the fuels they use, and ensuring that incentives no longer will be directed toward projects that can seriously undermine our climate objectives;
2. Curbing wasteful use of limited biomass resources by requiring most eligible facilities to meet a minimum efficiency standard of 50-60% (as compared to many existing facilities that are in the range of only 25% efficient);
3. Protecting forests against over harvesting of biomass fuels, for example by prohibiting the harvest of fuels from old growth forests or steep slopes that are vulnerable to erosion, requiring minimum amounts of tree tops and limbs to be retained on the forest floor to replenish nutrients and provide habitat, etc.

Hats off to the Patrick Administration and the team of policymakers who worked tirelessly to infuse the science into such an important policy! They appear to have done a remarkable job balancing many competing interests and considerations, setting a standard that we hope other states and the nation will follow.

If a tree falls in the forest in order to fuel in an inefficient electric power plant, does it make noise?  You bet it does.  This morning, dozens of advocates rallied at the Massachusetts State House to make a little noise while calling for the strengthening of the Commonwealth’s rules for forest wood-fueled – i.e., “biomass” – energy incentives.

Last year, we cheered as the Patrick Administration commissioned a ground-breaking study, known as the “Manomet Report,” to help understand the climate impacts of biomass energy.  That Report reaffirmed a growing scientific understanding that burning whole trees for energy can be worse than burning coal because of what I refer to as the “double whammy” effect:  (1) the immediate release into the atmosphere of the carbon stored in the tree; and (2) the tree that has been cut no longer is available to absorb new carbon from the atmosphere – or help promote clean water, wildlife habitat, shade or other benefits.

Based on the Manomet Report, the Administration released an encouraging framework for revised biomass regulations that included the key policy pillars of science-based carbon accounting, strong sustainable harvesting requirements, and minimum efficiency standards for capturing the energy stored in biomass fuels.  Unfortunately, the latest version of the regulations and related guidance have been substantially weakened, treating all forms of biomass as “carbon neutral” over a short period of time, promoting the removal of all harvest residues from the forest floor, and encouraging the cutting of whole trees for biomass fuel.  This retreat is disturbing both in terms of likely impacts in Massachusetts and the precedent it would set for other states, the nation, and beyond.

As we spelled out at today’s State House rally, Massachusetts still has an historic opportunity to “get it right”.  To make this happen, CLF and many others are asking for three simple things:

1.       The final biomass regulations must be based on the SCIENCE, consistent with the core lessons of the Manomet Report;

2.       Incentives must be reserved for practices that DO NO HARM to our forests, for example by leaving sufficient tree tops and limbs in forests to replenish soil nutrients and provide habitat;

3.       Benefits should be limited to those practices and facilities that AVOID WASTE by efficiently using biomass fuel, ensuring that the majority of its energy potential is captured and used.

The specific changes to the draft rules that we are seeking are spelled out in greater detail here.

Massachusetts’ forests currently absorb a whopping 10% of all the greenhouse gas emissions we produce each year from electric power generation, transportation, heating, cooling and all other activities combined. This doesn’t mean that we need to leave all forests untouched – there is a role for sustainably harvested forest products of many kinds, just as there is a role for untouched forest reserves.  But we do need to watch out for the “double whammy” and make certain that limited ratepayer-funded clean energy dollars are not steered toward wasteful forest harvesting and combustion practices that would move us away from the clean energy future we seek.

CLF praised the Patrick Administration today for announcing its new regulations on biomass energy for Massachusetts. CLF has been instrumentally involved in the state’s  debate over biomass, helping to bridge the gap between environmental interests, forest advocates and policymakers in the state. CLF and others have fought for science-based rulemaking that would allow certain biomass projects to receive state subsidies only if they contribute to the state’s greenhouse gas reduction goals while ensuring protection of its valuable forestry resources.

“We are encouraged that the state has looked to the latest science and public input to craft these nation-leading regulations and to identify more responsible policies for biomass energy in Massachusetts,” said CLF Massachusetts Director Sue Reid. More >
