We used Comparative Risk Assessment methods to estimate the health effects of alternative urban land transport scenarios for two settings-London, UK, and Delhi, India. For each setting, we compared a business-as-usual 2030 projection (without policies for reduction of greenhouse gases) with alternative scenarios-lower-carbon-emission motor vehicles, increased active travel, and a combination of...

escalating development of tourism and petroleum industries in small islands such as lavan-iranrequires sound solid waste management. in the present investigation, three scenarios which consist of thecombination of landfill, recycling, incineration and composting and their environmental impacts have beenevaluated for 7514 kg/day of waste generation in lavan island. for this purpose, life cycle a...

We analyze the different regional and generational contributions to increases of C02 concentrations resulting from fossil-fuel use since the onset of the industrial revolution. Equitable future per capita emission allowances under a range of concentration stabilization scenarios (additional 140, 280, and 420 ppm over pre-industrial levels) by the year 2100 are outlined. The intraand inter-gener...

Abstract. Air pollution is a major issue in China and one of the largest threats to public health. We investigated future changes atmospheric circulation patterns associated with haze events Beijing region severity during these conditions from 2015 2049 under two different aerosol scenarios: maximum technically feasible reduction (MTFR) current legislation scenario (CLE). In both cases greenhou...

The Colombian Orinoco savannas (254 thousand km 2 ), also known as Orinoquia or Llanos, have been steadily transformed into pastures for more than a century, and since the 1990s, commodity crop intensified production. cropland area expanded at 12% yr ?1 during 2007–2018 period (65% larger in 1996–2007). Yet, we estimate that cattle ranching occupied ten times (34%) (3.2%) 2018. rest of Orinoqui...

Mass casualty and pandemic events pose a substantial challenge to the resources available in our current health care system. The ability to provide adequate oxygen therapy is one of the systems that could be out-stripped in certain conditions. Natural disasters can disrupt manufacturing or delivery, and pandemic events can increase consumption beyond the available supply. Patients may require m...

According to the previous pieces of research, the building sector consumes about 40 % of total yield energy and produce one-third of GHG pollution emission. This point shows the significant potential in two aspects of energy optimization and pollution reduction in this field. The purpose of this research as a case study is to construct a residential building and develop the paths for reaching a...

This paper presents a computational framework for optimal design of non-prismatic reinforced concrete box girder bridges. The variables include the geometry of the cross section, tapered length, concrete strength and reinforcement of box girders and slabs. These are obtained by the enhanced colliding bodies optimization algorithm to optimizing the cost and again CO2 emission. Loading and design...

This paper is an examination of carbon dioxide emission mitigation scenarios within the forestry and energy sectors in Mexico. It is primarily intended to illustrate how, using a proper strategy, it is possible to identify development options that result in significant CO2 emission reductions while simultaneously advancing national sustainable development priorities. 1
