IPCC Mitigation of Climate Change report released

The Intergovernmental Panel on Climate Change released its report on Mitigation of Climate Change on 04 May 07 in Bangkok. Here is what the Summary for Policymakers says about the transport sector.

11. There are multiple mitigation options in the transport sector , but their effect maybe counteracted by growth in the sector. Mitigation options are faced with many barriers, such as consumer preferences and lack of policy frameworks (medium agreement, medium evidence).

  • Improved vehicle efficiency measures, leading to fuel savings, in many cases have net benefits (at least for light-duty vehicles), but the market potential is much lower than the economic potential due to the influence of other consumer considerations, such as performance and size. There is not enough information to assess the mitigation potential for heavy-duty vehicles. Market forces alone, including rising fuel costs, are therefore not expected to lead to significant emission reductions.
  • Biofuels might play an important role in addressing greenhouse gas (GHG) emissions in the transport sector, depending on their production pathway. Biofuels used as gasoline and diesel fuel additives/substitutes are projected to grow to 3% of total transport energy demand in the baseline in 2030. This could increase to about 5-10%, depending on future oil and carbon prices, improvements in vehicle efficiency and the success of technologies to utilise cellulose biomass.
  • Modal shifts from road to rail and inland waterway shipping and from low-occupancy to high-occupancy passenger transportation, as well as land-use, urban planning and non-motorized transport offer opportunities for GHG mitigation, depending on local conditions and policies.
  • Medium term mitigation potential for CO2 emissions from the aviation sector can come from improved fuel efficiency, which can be achieved through a variety of means, including technology, operations and air traffic management. However, such improvements are expected to only partially offset the growth of aviation emissions. Total mitigation potential in the sector would also need to account for non-CO2 climate impacts of aviation emissions.
  • Realizing emissions reductions in the transport sector is often a co-benefit of addressing traffic congestion, air quality and energy security.

  1. thanks for the info.I”l check it for another section such agriculture or forest related.

    Biofuel might play important role?
    hmm..that’s correct,we must see how biofuel made, where it from and how it made by.
