A necessary prerequisite for impactful climate mitigation action is the availability of suitable and reliable baselines of emissions. This is especially true for urban and citylevel actions and strategies that need reliable local data about emissions to prioritize actions and investments to achieve the highest possible impact. We describe the work of the Carbon Track and Trace project (CTT) don...

BACKGROUND Since sugarcane areas have increased rapidly in Brazil, the contribution of the sugarcane production, and, especially, of the sugarcane harvest system to the greenhouse gas emissions of the country is an issue of national concern. Here we analyze some data characterizing various activities of two sugarcane mills during the harvest period of 2006-2007 and quantify the carbon footprint...

NH3, CH4 and N2O emissions from dairy cattle and pig slurries were quantified. The effect of the following treatments was investigated: untreated covered slurry, mechanically separated slurry, anaerobically digested slurry, slurry covered with a layer of straw, and slurry aeration. Measurements were carried out with dairy cattle and with pig slurry, in winter and in summer. After storage, slurr...

1 Pete Smith has been a Coordinating Lead Author for Chapter 8 " Agriculture " of the IPCC Working Group III fourth assessment report "Mitigation of Climate Change". Abstract Energy efficiency and greenhouse gas emissions are closely linked. This paper reviews agricultural options to reduce energy intensities and their impacts, discusses important accounting issues related to system boundaries,...

In light of concerns over climate change and the need for national inventories for greenhouse gas reporting, there has been a recent increase in interest in the ‘carbon foot printing’ of products. A number of LCA-based carbon reporting tools have been developed in both the agricultural and renewable energy sectors, both of which follow calculation methodologies to account for GHG emissions from...

This paper sets out my comments on DEFRA's new guidance on how to price greenhouse gas emissions – 'carbon' for short – into economic appraisal in the UK. The DEFRA paper begins by drawing a distinction between the social cost of carbon and the shadow price of carbon for use in government economic appraisal in the UK. While the terminology is confusing, this is an improvement on previous guidan...

reducing co2 emission and lowering the concentration of greenhouse gases in the atmosphere has quickly become one of the most urgent environmental issues. while a variety of technologies and methods have been developed, the separation of co2 from gas streams is still a critical issue. apart from establishing new techniques, the exploration of membrane materials with high separation performance ...

Agriculture contributes about 60% of New Zealand’s total greenhouse gas emissions. Management practices for reducing these emissions will be required to meet our future international commitments. This paper presents estimates of two practical on-farm measures for reducing total greenhouse gas emissions from an average dairy farm on the West Coast of the South Island of New Zealand: 1) the incor...

The 2007 Bali conference heard repeated calls for reductions in global greenhouse gas emissions of 50 per cent by 2050 to avoid exceeding the 2 degrees C threshold. While such endpoint targets dominate the policy agenda, they do not, in isolation, have a scientific basis and are likely to lead to dangerously misguided policies. To be scientifically credible, policy must be informed by an unders...
