Description: The field of nutrition will face numerous challenges in coming decades; these arise from changing lifestyles and global consumption patterns accompanied by a high use of resources. Against this background, this paper presents a newly designed tool to decrease the effect on nutrition, the so-called Nutritional Footprint. The tool is based on implementing the concept of a sustainable diet in decision-making processes, and supporting a resource-light society. The concept integrates four indicators in each of the two nutrition-related fields of health and environment, and condenses them into an easily communicable result, which limits its results to one effect level. Applied to eight lunch meals, the methodology and its calculations procedures are presented in detail. The results underline the general scientific view of food products; animal-protein based meals are more relevant considering their health and environmental effects. The concept seems useful for consumers to evaluate their own choices, and companies to expand their internal data, their benchmarking processes, or their external communication performance. Methodological shortcomings and the interpretation of results are discussed, and the conclusion shows the tools' potential for shaping transition processes, and for the reduction of natural resource use by supporting food suppliers' and consumers' decisions and choice.

Description: The innovative software system "myEcoCost" enables to gather and communicate resource and environmental data for products and services in global value chains. The system has been developed in the consortium of the European research project myEcoCost and forms a basis of a new, highly automated environmental accounting system für companies and consumers. The prototype of the system, linked to financial accounting of companies, was developed and tested in close collaboration with large and small companies. This brochure gives a brief introduction to the vision linked to myEcoCost: a network formed by collaborative environmental accounting nodes collecting environmental data at each step in a product's value chains. It shows why better life cycle data are needed and how myEcoCost addresses and solves this problem. Furthermore, it presents options for a future upscaling of highly automated environmenal accounting for prodcuts and services.

Description: Sea level oscillations are the superposition of many contributions. In particular, tide is a sea level up-down water motion basically depending on three different phenomena: the Earth-Moon-Sun gravitational relationship, the water surface fluid reaction to atmospheric meteorological dynamic, and the Newtonian vertical adjustment of the sea surface due to atmospheric pressure variations. The first tide component (astrotide) is periodic and well known in all points of the Earth surface; the second one is directly related to the meteorological phenomenon, and then it is foreseeable; the Newtonian component, on the contrary, is not readily predictable by a general hydrostatic law, because the 𝐽 factor that represents the Newtonian transfer (from the atmospheric weight to the consequent sea level) is variable in each harbor area.The analysis of the gravity field permits to forecast the sea level variation due to meteorological tide events, and itsmetrological analysis highlights a compensation in the inverse hydrobarometric factor to be taken into account to correctly compensate atmospheric pressure variations in semibinding basins. This phenomenon has several consequences in HarborWaterside management and in water quality control as shown by the reported case studies and introduces a new reference parameter: the so-calledWater 1000.

Description: Many countries have started to develop policy programs for the sustainable use of natural resources. Indicators and targets can cover both a territorial and a life-cycle-wide global perspective. This article focuses on how a safe operating space for global material resource use can be outlined based on existing economy-wide material flow indicators. It reflects on issues such as scale and systems perspective, as the choice of indicators determines the target "valves" of the socio-industrial metabolism. It considers environmental pressures and social aspects of safe and fair resource use. Existing proposals for resource consumption targets are reviewed, partially revisited, and taken as a basis to outline potential target values for a safe operating space for the extraction and use of minerals and biomass by final consumption. A potential sustainability corridor is derived with the Total Material Consumption of abiotic resources ranging from 6 to 12 t/person, the Total Material Consumption of biotic resources not exceeding 2 t/person, and the Raw Material Consumption of used biotic and abiotic materials ranging from 3 to 6 t/person until 2050. For policy, a "10-2-5 target triplet" can provide orientation, when the three indicators are assigned values of 10, 2, and 5 t/person, respectively.

Description: Germany intends to present the Working Group on Ecosystem Monitoring and Management (WG EMM) the background document that provides the scientific basis for the evaluation of a marine protected area (MPA) in the Weddell Sea planning area. The contents and structure of the whole document reflect its main objectives, i.e. to set out the general context of the establishment of MPAs and to provide the background information on the Weddell Sea MPA (WSMPA) planning area (Part A); to inform on the data retrieval process (Part B), and to describe the results of the scientific analyses and the MPA scenario development with the directly science-based aspects of the WSMPA proposal, i.e. the objectives and the boundaries and zones of the MPA (Part C). Here, the authors intend to update WG EMM on the current state of Part C of the scientific background document. Part C informs on the data analysis and the MPA scenario development that were carried out within the framework of the WSMPA project. Chapter 1 contains an update of the data analysis that has been presented in our background document SC-CAMLR-XXXIII/BG/02, and had welcomed and endorsed as a foundation reference document for the Weddell Sea MPA planning by the Scientific Committee (SC-CAMLR-XXXIII, § 5.21). Chapter 2 provides a systematic overview of the newly conducted MPA scenario development. The proposed objectives (subchapter 2.1), borders (2.4) and zoning related aspects (based on subchapter 2.5) are intended to be incorporated in the WSMPA proposal.

Description: Accurate assessment of anthropogenic carbon dioxide (CO2) emissions and their redistribution among the atmosphere, ocean, and terrestrial biosphere is important to better understand the global carbon cy- cle, support the development of climate policies, and project future climate change. Here we describe data sets and a methodology to quantify all major components of the global carbon budget, including their uncertainties, based on the combination of a range of data, algorithms, statistics, and model estimates and their interpretation by a broad scientific community. We discuss changes compared to previous estimates as well as consistency within and among components, alongside methodology and data limitations. CO2 emissions from fossil fuels and industry (EFF) are based on energy statistics and cement production data, while emissions from land-use change (ELUC), mainly deforestation, are based on combined evidence from land-cover-change data, fire activ- ity associated with deforestation, and models. The global atmospheric CO2 concentration is measured directly and its rate of growth (GATM) is computed from the annual changes in concentration. The mean ocean CO2 sink (SOCEAN) is based on observations from the 1990s, while the annual anomalies and trends are estimated with ocean models. The variability in SOCEAN is evaluated with data products based on surveys of ocean CO2 measurements. The global residual terrestrial CO2 sink (SLAND) is estimated by the difference of the other terms of the global carbon budget and compared to results of independent dynamic global vegetation models forced by observed climate, CO2, and land-cover change (some including nitrogen–carbon interactions). We compare the mean land and ocean fluxes and their variability to estimates from three atmospheric inverse methods for three broad latitude bands. All uncertainties are reported as ±1σ, reflecting the current capacity to charac- terise the annual estimates of each component of the global carbon budget. For the last decade available (2005– 2014), EFF was 9.0 ± 0.5 GtC yr−1, ELUC was 0.9 ± 0.5 GtC yr−1, GATM was 4.4 ± 0.1 GtC yr−1, SOCEAN was 2.6 ± 0.5 GtC yr−1, and SLAND was 3.0 ± 0.8 GtC yr−1. For the year 2014 alone, EFF grew to 9.8 ± 0.5 GtC yr−1, 0.6 % above 2013, continuing the growth trend in these emissions, albeit at a slower rate compared to the average growth of 2.2 % yr−1 that took place during 2005–2014. Also, for 2014, ELUC was 1.1 ± 0.5 GtC yr−1, GATM was 3.9 ± 0.2 GtC yr−1, SOCEAN was 2.9 ± 0.5 GtC yr−1, and SLAND was 4.1 ± 0.9 GtC yr−1. GATM was lower in 2014 compared to the past decade (2005–2014), reflecting a larger SLAND for that year. The global atmospheric CO2 concentration reached 397.15 ± 0.10 ppm averaged over 2014. For 2015, preliminary data indicate that the growth in EFF will be near or slightly below zero, with a projection of −0.6 [range of −1.6 to +0.5] %, based on national emissions projections for China and the USA, and projections of gross domestic product corrected for recent changes in the carbon intensity of the global economy for the rest of the world. From this projec- tion of EFF and assumed constant ELUC for 2015, cumulative emissions of CO2 will reach about 555 ± 55 GtC (2035 ± 205 GtCO2) for 1870–2015, about 75 % from EFF and 25 % from ELUC. This living data update docu- ments changes in the methods and data sets used in this new carbon budget compared with previous publications of this data set (Le Quéré et al., 2015, 2014, 2013). All observations presented here can be downloaded from the Carbon Dioxide Information Analysis Center (doi:10.3334/CDIAC/GCP_2015).

Description: Reconstructions of Quaternary climate are often based on the isotopic content of paleo-precipitation preserved in proxy records. While many paleo-precipitation isotope records are available, few studies have synthesized these dispersed records to explore spatial patterns of late-glacial precipitation δ18O. Here we present a synthesis of 86 globally distributed groundwater (n = 59), 
cave calcite (n = 15) and ice core (n = 12)
 isotope records spanning the late-glacial (defined as
 ~ 50000 to ∼ 20000 years ago) to the late-Holocene (within the past ∼5000 years). We show that precipitation δ18O changes from the late-glacial to the late-Holocene range from −7.1 ‰ (δ18Olate-Holocene 〉 δ18Olate-glacial) to +1.7 ‰ (δ18Olate-glacial 〉 δ18Olate-Holocene), with the majority (77 %) of records having lower late-glacial δ18O than late-Holocene δ18O values. High-magnitude, negative precipitation δ18O shifts are common at high latitudes, high altitudes and continental interiors (δ18Olate-Holocene 〉 δ18Olate-glacial by more than 3‰). Conversely, low-magnitude, positive precipitation δ18O shifts are concentrated along tropical and subtropical coasts (δ18Olate-glacial 〉 δ18Olate-Holocene by less than 2 ‰). Broad, global patterns of late-glacial to late-Holocene precipitation δ18O shifts suggest that stronger-than-modern isotopic distillation of air masses prevailed during the late-glacial, likely impacted by larger global temperature differences between the tropics and the poles. Further, to test how well general circulation models reproduce global precipitation δ18O shifts, we compiled simulated precipitation δ18O shifts from five isotope-enabled general circulation models simulated under recent and last glacial maximum climate states. Climate simulations generally show better inter-model and model-measurement agreement in temperate regions than in the tropics, highlighting a need for further research to better understand how inter-model spread in convective rainout, seawater δ18O and glacial topography parameterizations impact simulated precipitation δ18O. Future research on paleo-precipitation δ18O records can use the global maps of measured and simulated late-glacial precipitation isotope compositions to target and prioritize field sites.

Chapter 1 describes the environmental data sets that were acquired for the evaluation of MPAs in the Weddell Sea planning area. Chapter 2 provides a systematic overview of the current data situation regarding ecological data sets. Most data sets are already presented in our background document SC-CAMLR-XXXIII/BG/02, which the Scientific Committee had welcomed and endorsed as a foundation reference document for the Weddell Sea MPA planning (SC-CAMLR-XXXIII, § 5.21).
