"Optimal Use of Carbon Sequestration in a Global Climate Change Strategy: Is there a Wooden Bridge to a Clean Energy Future?" by Franck Lecocq, Kenneth Chomitz, July 2001, World Bank, Development Economics Research Group, Infrastructure and Environment
Is carbon sequestration really a good way to "buy time" until new energy technologies become available and competitive? This paper tries to rigorously assess this argument using an economic model (an intertemporal optimization model) where both abatement of fossil fuel emissions and biomass sequestration can be used to mitigate climate change.
The paper sets up a climate policy optimization model with emission abatement and deforestation prevention. The objective is to minimize total costs of climate change, i.e. the sum of mitigation costs and climate change damages. There are two ways to achieve this objective: to reduce fossil-fuel emissions or to use carbon sequestration.
Through analyses of the cases of permanent and temporary sequestration, the paper presents the following insights:
"- When permanence can be guaranteed, sequestration is equivalent to abatement from fossil fuel combustion. Where it is impossible to guarantee permanence of individual projects, it may be possible to apply the same reasoning to portfolios of projects, adjusted for the expected proportion of non-permanent projects.
- Explicit contracts for temporary sequestration make sense only when the rationale for mitigation is reduction of damages, and current marginal damages of climate change are thought to be significant: sequestration is then cost-effective because it postpone damages. In this case, there's a rationale to begin temporary sequestration contracts immediately, and they will probably be renewed indefinitely.
- Such temporary sequestration contracts also make sense when the rationale for mitigation is keeping concentration below some threshold, but only when concentrations are approaching that threshold. Here the sequestration project serves to bridge the "hump" of high energy abatement costs. Under this rationale, sequestration follows a "bang-bang" optimal dynamics, and begins immediately only if the goal is to stabilize at very low concentration levels."
Although the paper sees only limited usefulness of temporary carbon sequestration based on the argument of "buying time" for new technologies, it does not rule out its usefulness on other grounds, such as the chances of bringing about permanent changes in land management practices, the value in saving time to gain information, and so on.

- Carbon sinks and Biodiversity Conference
The Ministry of the Walloon Region in Belgium is organizing an international conference on 'Carbon sinks and Biodiversity'. The conference will take place in Liege, Belgium, from 24 to 26 October 2001, just before the 7th Conference of the Parties (COP-7) of the UNFCCC.
The conference aims to contribute to increase synergies among the various stakeholders (scientists, foresters, agronomy and nature conservation experts, NGO and decision makers). It is expected to address useful recommendations for conciliating land use, carbon sequestration and biodiversity to the European Union and international fora such as the CBD and the UNFCCC.
The conference on "Carbon sinks and Biodiversity" will be organized in five sessions: general introduction, forest ecosystems, agricultural lands, other terrestrial ecosystems and "Recommendations".

Contribution by André Gabus: After the climate compromise in Bonn:.
ECO GROUPS ARE GOOD PLAYERS BUT RESTORING DEGRADED NATURAL FORESTS IN DEVELOPING COUNTRIES IS TO WAIT FOR QUALIFYING AS CARBON OFFSET
Environmental groups definitely won a battle when convincing European governments to resist that forests should be used as "sinks" to soak up carbon dioxide in the atmosphere. As recognized later, this position led to the collapse of the previous round of talks for implementing the Kyoto Protocol in The Hague last November. For reaching an agreement in Bonn, the European Union had to accept a certain amount of sinks. These groups can be considered as good losers about this issue, when reading their respective recent declarations (see Box 1: Eco Groups - What They Said Before & After). ...
Furthermore, they are modest winners in keeping a low profile on this other issue (open by them) about the Clean Development Mechanism (CDM) for the South. It is now confirmed that, in developing countries, forest sinks will be limited to only afforestation or reforestation activities. A request from a number of Umbrella Group countries (Japan, Australia, New Zealand, Canada, United States) that an option be included providing for all sinks project types within the CDM was rejected in Bonn.
As a result, enriching plantations on degraded natural forests are excluded for certified emissions reduction credits, at least for the first commitment period 2008-2012 (see Box 2: Decisions and Definitions). It is a pity in particular for Western and Central African countries where forest industries were prepared in some cases to help reconstituting natural forest with commercial plantations. ...
For sure, operators interested in both timber harvesting and carbon dioxide absorption in the tropics within the CDM will have the possibility to carry on projects on deforested lands (as defined in Box 2). However these lands are occupied by agriculture in most countries where restoring forests is most needed. ...
Under these conditions, the Kyoto Protocol will give poor chances to a new departure of forestry in developing countries. ...

While 178 nations compromised on language for the Kyoto Protocol and set
the stage for individual country ratification of the treaty, the U.S.
did not participate. Ironically, many of the deals struck in Bonn fell
in the direction the U.S. has long favored. Virtually all the important
compromises addressed the costs of meeting a country's Kyoto target. But
none involved enforceable actions, as Raymond J. Kopp discusses in this
