The Impact

This chapter examines the impact of improving feed efficiency on the environmental impact of livestock production. It starts by discussing the relation between greenhouse gases and dairy production, highlighting how important it is to the dairy sector to find ways of decreasing greenhouse gas output. The chapter then moves on to discuss the origins of methane and reactive nitrogen excretions in ruminants. A section on improving feed conversion efficiency is also included, which is then followed by a review of the nutritional practices that can be used to enhance feed conversion efficiency and decrease methane excretion. The chapter also examines the nutritional practices that can be used to increase milk protein efficiency and nitrous oxide excretion as well. Discussions on genetics and feed conversion efficiency and postabsorptive metabolism and feed conversion efficiency are also provided.

Climate Convention

The historical responsibility of countries listed in the Annex I of the Convention on Climate Change has been used extensively as a justification for the lack of action of countries not included in Annex I to reduce their greenhouse gas emissions. We analyzed the contribution of non-Annex I countries to the CO2 emissions in the period 1850 - 2006 to assess their relative contribution to total CO2 emissions. In the period 1980 - 2006 non-Annex I countries represented 44% of the total but this contribution increased in the period 1990 - 2006 to 48%. If we extrapolate present trends to 2020 they will represent 56% in the period 1990 - 2020. The "historical responsibility" of Annex I countries is therefore decreasing. If we take 1990 as the starting year in which the Climate Convention recognized clearly that greenhouse gases are interfering dangerously with the climate system, it becomes very difficult to attribute "blame" and "guilt" to Annex I for their historical contributions. It becomes also quite clear the need of non-Annex I countries to engage with Annex I countries in the effort to reduce emissions. The Copenhagen Accord has no mention of "historical responsibilities".

Global Carbon

There is strong scientific consensus that the concentration of greenhouse gases in the atmosphere is increasing due to human activities and that this is leading to changes in the Earth’s climate. Fluxes between terrestrial ecosystems and the atmosphere are a significant component of the global carbon cycle and actions to increase net storage in terrestrial ecosystems (often called sinks) will delay the build up of greenhouse gases in the atmosphere. There is still political debate as to which sinks may be accounted in compliance with the Kyoto Protocol. The decisions made will affect the total costs of compliance with the Kyoto Protocol by a factor or two to four. Geological sequestration may also reduce emissions by an amount of the same order as sequestration in terrestrial sinks. Biological and geological sequestration offer a significant opportunity to buy several decades of time to make an efficient transition to technologies and economies that release less greenhouse gasses to the atmosphere from energy production and industrial processes.

The United States is moving closer to enacting a policy to reduce domestic emissions of greenhouse gases. A key element in any plan to reduce emissions will be to place a price on greenhouse gas emissions. This paper discusses the different approaches that can be taken to price emissions and assesses their strengths and weaknesses.

Dangerous Climate Change

Emissions of CO2 and other greenhouse gases can be reduced significantly using existing technologies, but stabilizing concentrations will require a technological revolution—a “revolution” because it will require fundamental change, achieved within a relatively short period of time. Inspiration for a climate–technology revolution is often drawn from the Apollo space program or the Manhattan Project, but averting dangerous climate change cannot be “solved” by a single new technology, deployed by a single government. The technological changes needed to address climate change fundamentally will have to be pervasive; they will have to involve markets; and they will have to be global in scope. My focus in this paper is not on the moderate emission reductions that can be achieved using existing technologies, but on the breakthrough technologies that are needed to reduce emissions dramatically. The challenges are formidable. Indeed, it is possible that the revolution needed to dramatically reduce emissions of greenhouse gases will fail. Should the climate change abruptly, the incentive to “engineer” the climate will be strong. There will be a climate–technology revolution, but its nature will depend on the institutions we develop to address the challenge we face.

Reduce Emissions

There is a long way to reduce emissions with the high speed of urbanization and economic growth in Beijing. In this article, depend on the IPCC country listing guidelines of greenhouse gases, carbon emissions has been calculated of Beijing beteeen1992-2011, then analysis of its historical characteristics . Beijing should seize the opportunity to research and carry out carbon recycling and energy saving technology in a planned and staged way.

There is growing concern about climate change resulting from increasing concentrations of greenhouse gases (GHGs) in the atmosphere. Several techniques including efficiency improvements and increased use of renewable energy sources will be needed to limit emissions of greenhouse gases to the atmosphere. Another technique that can help to reduce emissions substantially is capture and storage of CO2 (CCS). This article will describe the main technologies that can be used to capture CO2 from coal- and gas-fired power plants, including postcombustion capture, precombustion capture, and oxy-combustion. The current status of these technologies, their performance and costs, and possible future developments will be reviewed. The article considers changes in CO2 capture technologies, fuel costs, and plant construction costs that have occurred since the Intergovernmental Panel on Climate Change (IPCC) Special Report on CCS was written. The article will draw on work carried out by the IEA Greenhouse Gas R&D Programme and other leading organizations working in this field. The analysis concentrates on coal-based gasification combined cycle power plants with precombustion capture and pulverized coal combustion plant with postcombustion capture.
