Bioenergy to feature prominently in IPCC report on mitigating climate change
A draft UN report on the economics of global warming outlines the potential for big curbs in greenhouse gas emissions by 2030. The study, by the Intergovernmental Panel on Climate Change (IPCC), is due for release in Bangkok on May 4 after approval by scientists and more than 100 governments. It will be the result of the IPCC's Working Group III, following up on the previous reports (by Working Group I - which studied the fundamental scientific evidence for climate change, and Working Group II - which looked at the impacts on natural and human ecosystems). This third part will complete the IPCC's Fourth Assessment Report on Climate Change.
The draft recognises the potential bioenergy can play in reducing greenhouse gas emissions. Total emissions from human activities on this planet, mainly from burning fossil fuels, amounted to about 40 billion tonnes in 2000. The table (click to enlarge) outlines the potential cuts that can be made per economic sector under a low and a high investment scenario. It assumes that prices for emitting carbon dioxide, the main greenhouse gas, stay below €74/US$100 a tonne (current price in Europe: €0.79).
The sneak preview lists some approaches to curbing emissions per sector, and the contribution of both current and future technologies (bioenergy's contribution in italics).
Curbs from existing technologies:

The sneak preview lists some approaches to curbing emissions per sector, and the contribution of both current and future technologies (bioenergy's contribution in italics).
Curbs from existing technologies:
- Energy supply: more efficient supply and distribution, combined heat and power, switching from high-polluting coal to cleaner gas, nuclear power and renewable energies such as hydropower, solar, wind, geothermal and bioenergy. Can also include some early applications of carbon capture and storage, including bioenergy with carbon capture and storage, which is a carbon negative energy system.
- Transport: more fuel-efficient vehicles, hybrids, cleaner diesel, better public transport, bicycles.
- Buildings: efficient lighting, more effective insulation and ventilation, passive solar design for heating, cooling and ventilation, more efficient electrical appliances and heating and cooling devices, alternative refrigerants, better recycling.
- Industry: efficient electrical equipment, heat and power reuse, material recycling, control of non carbon dioxide gases.
- Agriculture: Improved management of crop and grazing land to improve soil carbon storage, restoration of degraded lands, better rice cultivation. Improved management of livestock and manure to reduce methane emissions. Better use of fertilisers, bioenergy crops to replace fossil fuels.
- Forestry: planting more trees, slowing rates of deforestation and land degradation, use of wood for bioenergy to replace fossil fuels.
- Waste: tapping methane from landfills, incineration of waste with use of the energy, composting of organic waste, recycling and minimising waste.
- Energy supply: carbon capture and storage for gas, biomass or coal-fired power plants, advanced nuclear power and renewable energies. Note, carbon capture and storage applied to biomass results in a carbon negative energy system.
- Transport: hydrogen-powered fuel cell vehicles, second generation biofuels, more efficient aircraft, advanced electric and hybrid vehicles with better batteries.
- Buildings: integrated solar photovoltaic electricity supplies, smart metering and intelligent control.
- Industry: advanced energy efficiency, carbon capture and storage for cement, ammonia, fertiliser and steel production, inert electrodes for aluminium manufacture.
- Agriculture: genetic technologies to improve energy crops.
- Waste: biocovers and biofilters to improve methane oxidation

One LAST thing; It's probably not a good idea to tie your wagon to this global warming/climate change hooey too firmly. You don't need it. Most reasonable people think that we're getting somewhere near Peak Oil, and that we're nowhere near peak demand.
A quick survey of global oil suppliers (Iran, Nigeria, Venezuela, Russia, etc. ad infinitum) and a glance at the prevailing crude prices is all the smarts need to convince them that it's time to make a move, and that biofuels need to be looked at.
The reason I say this is that all of the articles by PHDs in the fields of Climatology, Geology, Meteorology, etc. have one thing in common. They unanimously cry, "Bunk!"
You don't want Bioenergy to get all wrapped up in the public consciousness with a soon-to-be discredited heap of hogwash.
You're only as "Credible" as those you "hang with."
Thas'sall. Good job, as always.
