BACKGROUND The typical Western diet is associated with high levels of greenhouse gas (GHG) emissions and with obesity and other diet-related diseases. This study aims to determine the impact of adjustments to the current diet at specific moments of food consumption, to lower GHG emissions and improve diet quality. METHODS Food consumption in the Netherlands was assessed by two non-consecutive...
malaysia, as a small and developing country, must reduce carbon emissions because the country is one of the top co2-emitting countries in the asean region. therefore, the current study implements two environmental tax policies; carbon and energy taxes, in order to examine the impacts of these policies on the reduction of carbon emission in the whole of the economy by applying a computable gener...
hydrogen technology is becoming ever more relevant because hydrogen use can help containinggreenhouse gas emission if co2 capture and storage techniques are implemented in the hydrogen productiontechnology (when hydrogen is produced from fossil fuels). for this reason this work aims at carryingout a comparative analysis of possible energy scenarios in urban districts: a medium-small italian cit...
Global generation of municipal solid waste (MSW) is now ~1200 Tg/yr (1 Tg = 10 g), >70% of which is landfilled. Landfilling of waste contributes ~30-35 Tg methane (CH4 )annually to the world's total CH4 emission of ~550 Tg/yr. Recycling and thermal treatment of waste in wasteto-energy (WtE) facilities contribute equally to diverting MSW from the waste stream destined for landfills and to mitiga...
A technology protocol to govern long-term international greenhouse gas emission reduction is proposed. The protocol consists of three parameters: a graduation income, below which countries have no emission reduction obligations; a convergence rate, at which emission intensities should approach that of the most carbon-extensive countries; and an acceleration rate, at the which the most carbon-ex...
Ozone and PM2.5 concentrations over the city of Paris are modeled with the CHIMERE air-quality model at 4 km× 4 km horizontal resolution for two future emission scenarios. A high-resolution (1 km× 1 km) emission projection until 2020 for the greater Paris region is developed by local experts (AIRPARIF) and is further extended to year 2050 based on regional-scale emission projections developed b...
background & objectives:airq software proved to be a valid and reliable tool to estimate the potential short term effects of air pollution. in this study the airq2.2.3 model was used to evaluate adverse health effects caused by nitrogen dioxide(no2) exposure in ahvaz during 2009. materials & methods:the airq,developed by the world health organization (who) to predict health endpoints a...
Background Climate change can directly affect human health by varying exposure to non-optimal outdoor temperature. However, evidence on this direct impact at a global scale is limited, mainly due to issues in modelling and projecting complex and highly heterogeneous epidemiological relationships across different populations and climates. Methods We collected observed daily time series of mean...
[1] This paper presents the first model-based forecasts of future emissions of the primary carbonaceous aerosols, black carbon (BC) and organic carbon (OC). The forecasts build on a recent 1996 inventory of emissions that contains detailed fuel, technology, sector, and world-region specifications. The forecasts are driven by four IPCC scenarios, A1B, A2, B1, and B2, out to 2030 and 2050, incorp...
