With the economic concerns, health care debate, and climate skepticism delaying any immediate action on climate change policy in Washington, the door has been left open for other climate policy proposals. The question facing farm and forest landowners during this time of uncertainty is: How can the agriculture and forestry sectors deliver GHG reduction benefits under any policy option on the table?

To date, the lion’s share of attention has been given to the cap-and-trade policy (i.e., the Waxman-Markey bill and the Kerry-Boxer bill). Under a cap-and-trade system the agriculture and forestry sectors are expected to be uncapped sectors and are expected to deliver substantial quantities of offsets to capped entities at an early stage in the game.  This could represent a multi-billion dollar a year revenue stream for American foresters and farmers.  However, if a cap-and-trade system is not the chosen policy, there are still opportunities under the other options being considered.

One policy option that has received increasing attention recently is the “cap-and-dividend” plan highlighted by Senators Cantwell and Collins in their CLEAR Act bill.  At the core of CLEAR is an upstream cap on fossil carbon as it enters the economy with a hundred percent auction of permits to energy producers.  75% of the revenue from the auction is returned as a cash refund to every legal citizen. 25% of the revenue is directed to a dedicated trust, the Clean Energy Reinvestment Trust (CERT).   In direct contrast to cap-and-trade legislation, there is no use of domestic or international offsets for meeting compliance obligations. However, the CERT would fund cost-effective reduction/sequestration projects that verifiably reduce, avoid, or sequester GHG emissions.

Another policy option, though not a politically attractive alternative, would be a carbon tax.  This could mirror a similar program as a cap-and-dividend program where additional reductions are financed via tax revenue.

The key to delivering GHG reductions or sequestration outside a cap-and-trade policy is to keep the program as administratively simple and cost-effective as possible.  This can be done.  The advantage of a cap-and-dividend, carbon tax, or hybrid, unlike a cap-and-trade program, is that reductions coming from the agriculture and forestry sectors are not needed for compliance. They will be purely additional reductions beyond the already established cap or tax.  Thus, reductions may not be subject to the same offset rules, (i.e. additional, verifiable, registered, and permanent) as a cap-and-trade system, because they do not sacrifice the integrity of the emission reductions target.

What does this mean? In straight speak, it means that these reductions may be cheaper to deliver than under a cap-and-trade program.   Because they might not have to prove “additionality” and incur the many monitoring and verification costs as a cap-and-trade offset, they could be rolled into programs that already exist, such as the USDA’s Conservation Reserve Program or Conservation Security Program or newly established programs like Senator Shaheen’s bill that calls for USDA to administer a forest carbon incentive program.

There are many questions facing the farm and forestry sectors: How does the quantity of reductions compare among the policy options? How do the costs of reductions compare?  In sum, how does the net revenue for agriculture and forestry sectors compare among policy options? Because many of the details needed to answer these questions have yet to be determined, it is difficult to say. However, the next step will be to quantify the reductions that can be delivered under the different policies, examine the costs of the policies, and compare the potential revenue streams to the agriculture and forestry sectors.

When the models we use generate answers which violate common sense, it is time to check the prevailing assumptions within. The Manomet study for Massachusetts, “Biomass Sustainability and Carbon Policy Study”, essentially concludes that global warming will be exacerbated by substituting forest biomass energy for fossil fuels for the production of electricity. I do not have to think very hard or long to conclude that digging up ancient carbon from coal, oil, and natural gas is unlikely to reduce greenhouse gas emissions as compared to growing renewable biomass in our forests and harvesting it for energy use. Yet, this is exactly what the Manomet study tells us, wrapped in massive amounts of very sophisticated analysis.

I have no wish to invalidate the strong work product produced by a stellar team regarding an analysis of prime importance: Will renewable forest biomass or fossil fuels best serve our needs for a low-carbon energy future (1)? I do suggest a need to examine the logic behind some of the prevailing assumptions – explicit and inherent – in this extensive analysis. Here then are questions which need to be answered:

1. How do you choose the point in the growth and harvest cycle for forest biomass at which to begin the analysis? Manomet chose to begin the life cycle analysis with the day of harvest. If they had taken the other extreme and started the analysis the day after harvest (the first day of sequestration), the results would have flipped entirely and showed the huge benefits of biomass over fossil fuels instead of the reverse finding. Intuitively, the biomass must be grown and the carbon sequestered before it can be combusted anyway. The most defensible answer is probably to begin the analysis midway between harvests which will improve the relative status of biomass substantially.
2. How does Manomet justify basing this study on the assumption that whole forest harvests will be used for biomass energy? The expert groups I have worked with refused to consider this extreme case because they considered it outside the bounds of reasonable likelihood. These other experts describe actual practices where forest thinnings and forest residuals and harvested biomass byproducts – along with agro forestry, and other purpose-grown biomass – are the current and expected future sources of bioenergy feedstocks.
3. When the analysis assumes the use of biomass energy sources, how does Manomet justify excluding the avoided emissions benefits from not mining fossil fuels? The analysis does not assess the avoided greenhouse gas emissions – not to mention the huge other environmental, social, and economic consequences – from reductions in mountain-top coal mining, Gulf of Mexico deep water drilling, and natural gas hydrofracking. Similarly, the greenhouse gas emissions associated with the entire infrastructure of activities supporting our fossil fuel economy need to be considered. For example, we would be less likely to have the Middle East wars and the U.S. military effort to protect shipping lanes if we grew our own fuel supplies instead of importing oil?
4. Which form of life cycle analysis is appropriate for this type of policy-informing analysis, attributional or consequential? Manomet does not specify which form of life cycle analysis they have used or the reasons they choose one over the other. Yet the differences in outcomes for this type of analysis can be material. It appears that consequential is the appropriate analysis framework for this study and that instead, attributional, the less appropriate form was implicitly chosen.
5. Does the Manomet study give proper acknowledgement to the manner in which harvesting energy biomass and generating carbon credits produces supplemental income streams which will keep land in forests which may have otherwise been converted to urban development? Manomet anecdotally dismisses this issue by noting that current green biomass payments to forest owners are minimal. Yet this study, which is intended to inform policy development for coming decades, should consider the more robust biomass pricing which will emerge under future national renewable energy standards and cellulosic biofuel production. Similarly, the inevitable price of carbon from future policy will enhance carbon credits as a source of income. Avoided loss of forestland is an issue which needs a robust treatment beyond that received here.

This note is authored by a reader who confesses to having found time for only a brief scan of the Executive Summary and Chapters 5 and 6, the chapters most relevant to the carbon accounting issues. In the event the above five questions were answered in a satisfactory manner elsewhere in the study, apologies to the authors.

1 Manomet and the author of this note would both assume that energy efficiency and other forms of renewable energy or low-carbon energy are important too. The purpose of Manomet analysis was keyed to a comparison between forest biomass and fossil fuels for electricity and thermal generation in Massachusetts.
