1) Current greenhouse gas emission reporting methods provide simple estimates that may not accurately reflect actual emissions and do not help guide mitigation.
2) Process-based models can provide more detailed and accurate estimates of emissions by taking into account factors like soil type, temperature, fertilizer use and crop growth, which inter-annual reporting methods do not.
3) Improving emission estimates through measurement data, refined models and reporting approaches can help develop agricultural systems that reduce environmental impacts from greenhouse gas emissions.
CCS Assessment in the Philippines - Carlo Arcilla and Raymond TanGlobal CCS Institute
This presentation was given as part of the CCS Ready workshop which was held in association with the 6th Asia Clean Energy Forum (20 – 24 June, Manila)
The workshop discussed the range of measures and best practices that can be implemented to prompt the design, permitting and construction of CCS projects when designing or building a new fossil fuelled energy or industrial plant.
The workshop hosted participants of the Asian Development Banks’ Regional Technical Assistance Program who updated the group on the outcomes of their individual projects.
This presentation provides an update on the current project being undertaken under the Asian Development Bank’s Regional Technical Assistance Program which aims to conduct an analysis of the potential for CCS, culminating in a road map for a CCS demonstration project in the Philippines.

Carbon dioxide, methane and nitrous oxide emissions from an oil palm plantati...CIFOR-ICRAF
Although nitrous oxide only makes up 8% of global greenhouse gas emissions, it has nearly 300 times the global warming potential of carbon dioxide. In this presentation, CIFOR scientist Kristell Hergoualc’h explains results from collaborative research between CIFOR, ICRAF, CIRAD and PT Bakrie, which show that nitrogen fertiliser can exacerbate the production of soil nitrous oxide greenhouse gases when applied to oil palms grown on deep peat. She gave this presentation on 23 February 2012 at the International Conference on Oil Palm & Environment (ICOPE) held in Bali, Indonesia. The conference had the theme ‘Conserving forest, expanding sustainable palm oil production’.

emissions from measurements and
modelling in the land use sector
Bob Rees, Kairsty Topp
ICARB workshop, 5 February 2013
2. Reporting metrics
• UK greenhouse gas emissions reported using
internationally agreed protocols (IPCC)
• Provide simple rule based accounting system
• Underpin C footprinting tools
• Unlikely to reflect actual emissions
• Unhelpful in guiding mitigation

• Current inventory reporting of agricultural GHG
emissions provide a crude estimate of actual
emissions
• Improved reporting will help improve the accuracy
of emissions and help to deliver mitigation
• Revised emission factors in improved modelling will
provide opportunities for the development of
farming systems with reduced environmental
impact
