Greenhouse gas emissions from bioenergy systems: impacts of timing, issues of responsibility
Brussels, Belgium, March 8th – 10th, 2010
Jointly organised by
Task 38 – Greenhouse Gas Balances of Biomass and Bioenergy Systems
Scope and objectives of the conference
The IEA Bioenergy Task38 conference on Greenhouse gas emissions from bioenergy systems: impacts of timing, issues of responsibility consists of two days of presentation and discussion on issues including
- How can indirect land use change due to bioenergy be quantified and managed?
- What is the impact of timing of GHG emissions from land use change, and emission reductions and sequestration associated with bioenergy systems?
- Who should take responsibility for GHG emissions due to land use change associated with bioenergy?
- Can policy mechanisms be used to recognize impacts of timing, and issues of responsibility?
The goals of the conference were:
- Share knowledge and increase understanding of the impacts of timing and issues of responsibility for greenhouse gas (GHG) emissions from bioenergy systems.
- Draft a summary document including recommendations, that will be circulated broadly, and presented to the IEA Bioenergy Executive Committee.
- Convey the key points and recommendations in a briefing paper for policy-makers, to inform negotiations toward the post-2012 climate change agreement.
- Enhance an informal alliance of researchers interested in these topics, currently known as the “Graz Group”, that will continue to discuss these issues and work together to draft journal papers and briefing papers for policy-makers
