Most importantly, new estimates of N2O emissions from agriculture and from oceans and a surface sink of N2O have been included. Our estimates confirm that current food production is the largest anthropogenic source of N2O. However, its relative share in total anthropogenic emissions (about 60%) is smaller than in earlier studies (almost 80%). We estimate past trends in global emissions of N2O and use these as input to a simple atmospheric box model to calculate trends in atmospheric N2O concentrations for the period 1500–2006. We show that our revised estimates for global emissions of N2O are consistent with observed trends in atmospheric concentrations.","PeriodicalId":411329,"journal":{"name":"Greenhouse Gas Measurement and Management","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115274661","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Expanding the MRV regime to include mitigation actions is an opportunity to support, rather than burden, developing countries in their efforts to improve their climate performance over time, consistent with sustainable development—if done in a sensible way. The article reviews the essence of this debate and suggests one pragmatic approach to ensure that national actions are indeed measurable, reportable and verifiable, namely adopting a certification scheme for national climate management systems (NCMS, which would require countries to establish a climate policy, set national goals and timetables, secure resources to implement related national actions and track their progress over time). Based on the high level of agreement among Parties to the United Nations Framework Convention on Climate Change (UNFCCC) on the need for comprehensive frameworks to facilitate forestry and energy sector mitigation by developing countries, supported by financial resources, technology and capacity building, an NCMS certification scheme is well suited to add value to the existing MRV regime both for developed and developing countries.","PeriodicalId":411329,"journal":{"name":"Greenhouse Gas Measurement and Management","volume":"56 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123070529","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Moreover, we show an approach that models these positions in a planned profit and loss account, taking into account uncertainties and dependencies.

To guarantee credibility of the international climate policy regime, robust measurement, reporting and verification procedures are required. Compared to concrete emission reduction projects, assessment of the additionality of NAMAs is difficult. As only a subset of policy options leads to directly quantifiable emission reductions, the challenge is to define procedures that are conservative and still provide incentives to embark on policies with long-term and indirect effects. This requires a combination of an approach using default parameters and monitoring of key factors. Experience from methodologies used under the Clean Development Mechanism should be taken into account. Analysis of a renewable energy feed-in tariff in Korea and a nationwide demand-side management programme in Thailand shows that for the former, additionality and emission impacts of policies can be assessed, but require centralized, transparent data collection systems, an effective sector organization. The latter is probably not suitable for NAMA crediting under a stringent approach. To provide incentives for a greater number of developing countries, more standardized approaches would be required to allow covering policies that are more difficult to quantify.","PeriodicalId":411329,"journal":{"name":"Greenhouse Gas Measurement and Management","volume":"75 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127264160","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This article explains the features and rationale of the output-based offset (OBO) approach, outlines a candidate accounting methodology, discusses the potential advantages and limitations of such an approach relative to the area-based offset (ABO) approach that is standard practice in some settings, and introduces possible policy implications. By incentivizing improvements in agricultural efficiency, the OBO approach strives to achieve the dual goals of food security and climate change mitigation. It expands the toolkit for achieving reductions in agricultural emissions, rewards technological advancement in both emission reductions and yields, and offers promise for addressing the problem of accounting for leakage. But because it is based on improvements in GHG efficiency in agriculture rather than on absolute reductions, emissions and climate risks could continue to rise while credits are being issued. An OBO approach might work best as a transitional strategy to address emissions from sectors or countries likely to remain outside a strict regulatory cap. Because it is the total atmospheric concentration of GHGs that creates the environmental threat of climate change, policies should ultimately focus not on the intensity of emissions but rather on their absolute levels.","PeriodicalId":411329,"journal":{"name":"Greenhouse Gas Measurement and Management","volume":"235 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133396772","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

There is currently minimal infrastructure in place to develop or support this workforce. I define GHG measurement and management, which also serves as the title of this journal, as the application of science, engineering and economic principles to improve the way in which society mitigates the anthropogenic causes of global climate change by developing and providing reliable performance metrics related to GHG emissions and removals, and managing activities intended to reduce emissions to, and/or increase removals from, the atmosphere.
