Carbon Budget for Basic Needs:Implications of International Equity and Sustainability

The fundamental way of satisfying the basic needs of human development is to secure the basic needs,limit luxurious and wasteful emissions,and ensure the fulfillment of climate targets,so as to achieve intra-and intergenerational equity.In this paper,the author discusses and analyzes a series of challenges that the development has to face,such as poverty elimination,urbanization,and industrialization,and the problems of increased consumption that is brought about by the improvement of living standards;the author distinguishes the stock emission,which does not need annual updating,and the flow emission of regular consumption;the author also defines the standards of energy consumption and carbon emissions that can meet the basic needs.On this basis,the author proposes the concept and method of carbon budget,compares this method with other means,and in particular,studies and analyzes the implications of international equity and sustainability of carbon budget as part of the international climate regime design.     

The Concept and Theoretical Implications of Carbon Emissions Rights Based on Individual Equity

Climate change has become a hot topic in international environmental negotiations.For post-Kyoto international climate regime negotiations,many countries have proposed a variety of frameworks to share the emission reduction responsibilities and allocate carbon emission rights,and have tried to quantify the emission reduction obligations of all countries based on the perspectives of international equity and individual equity.In this paper,the authors have distinguished the concepts of carbon emissions rights based on these two perspectives respectively,have analyzed the relationship between carbon emissions per capita and economic development,and have calculated and compared the proportion of cumulative emissions per capita of different countries in history and future,and then authors conclude that emission reduction obligations should be allocated based on each country’s conditions,including historical emissions,development stage,and future demands.Developed countries should take the initiative to significantly reduce their emissions because they have already accomplished their industrialization process.However,developing countries are still in the process of industrialization,which requires more emission rights to meet their development needs.For China,the concept of carbon emissions based on individual equity can be used as a theoretical tool for the allocating the international carbon emissions rights.     

无机稳定剂处理重金属污染土壤

以重金属污染土壤为研究对象,比较了铁屑、蒙脱石、碳酸钙和羟基磷灰石4种稳定剂对土壤中Pb,Zn,Cd,Cu 4种重金属的稳定效果。实验结果表明,4种稳定剂稳定效率的大小顺序为：羟基磷灰石﹥碳酸钙﹥蒙脱石﹥铁屑。当稳定剂质量分数为10%时,羟基磷灰石、碳酸钙、蒙脱石和铁屑对Pb,Zn,Cd,Cu 4种重金属的平均稳定效率分别为99.63%,98.53%,97.15%,86.95 %。未加稳定剂时,土壤中的Pb以残渣态为主,Zn以残渣态和可交换态为主,Cd以残渣态为主,Cu以残渣态和可交换态为主;加入稳定剂后,土壤中4种金属可交换态的所占比例（简称占比）均显著降低,还原态的占比明显增大,残渣态的占比略有增大,氧化态的占比基本保持不变。     

再生水的环境安全管理机制研究

探讨了再生水回用潜在的环境安全问题,以及导致这些问题的原因。并提出了再生水安全回用的管理机制。建立再生水回用安全管理体系,是再生水回用政策得以顺利推进的基础。这一安全管理体系的建设应包括有关鼓励再生水回用的政策法规保障体系、标准体系、技术支持和安全管理手段。
