Developing an IFC interoperabilityspecification for integrated and energyefficient building design
Human activities release greenhouse gases (GHG) that are warming and changing theclimate and putting at risk the life on the planet. Among these activities, the buildingsector has an important position as it consumes 30-40% of global energy. The primary useof energy is domestic heating, and it …

Observing Seasonal Cycles in Greenhouse Gas Fluxes with Automatic Flushing Chambers in a Low-Arctic Lake
… four times faster than the global average. Greenhouse gases (GHG) are causing a changing climate which is affecting permafrost thaw, sea ice melt, and changing hydrological dynamics. Lakes in the Arctic and sub-Arctic regions are increasingly recognised as important actors in the global …

Human Health Impact and Environmental Footprint of Transport Network Generated by Oil Sands In-Situ Thermal Facilities in West-Central Saskatchewan
Greenhouse gas (GHG) and air pollutant emissions are major contributors to global warming and environmental disruption. In Canada, the transportation sector is the leading source of air pollutants and the second largest source of GHGs; a similar pattern is observed in Saskatchewan. In west-central …

Trace Greenhouse Gas Fluxes in Upland Forests
Tree stems can act as a conduit for trace greenhouse gases (GHG) produced in the soil. However, the majority of studies describing tree stem fluxes of methane (CH₄) and nitrous oxide (N₂O) have focused on wetland ecosystems. Tree stem fluxes of GHGs on free-draining soils are understudied, but they …

Application of spatial planning strategies to achieve sustainable transport systems in rapidly urbanizing cities : a study of Abuja, Nigeria
… fuel loss and growing transport-related greenhouse gas emissions. Earlier studies have attributed these impacts to the legacy of the Modernist Planning/Master Planning paradigm which prevails in rapidly urbanizing cities in the global south region. While this strategic instrument is …

The Greatest Generation : a new retail store model for delivering energy efficiency in Massachusetts
The mitigation of greenhouse gases (GHG) and reduced energy consumption in the United States has proven to be a great challenge in the face of climate change. While technological innovation and renewable energy continue to evolve and scale to meet growing energy demands, energy efficiency has been …

The potential of airborne polarimetric synthetic aperture radar data for quantifying and mapping the biomass and structural diversity of woodlands in semi-arid Australia.
… in these levels of carbon dioxide and other greenhouse gases (GHG), with significant changes in climate predicted long term. The adoption of the Kyoto Protocol in 1997 heralded a new age in terms of greenhouse gas accounting and emissions responsibility, for all nations. In Australia, carbon …

Carbon Accounting in the Arboriculture Industry; Reduction of Greenhouse Gas Emissions from Tree Surgery
Increasing atmospheric concentrations of greenhouse gases (GHG) have been directly attributed to human activity; burning fossil fuels, land use change e.g. deforestation and energy production. Current practices in arboriculture rely heavily on fossil fuel based equipment to maintain trees in urban …

Beyond Health Co-Benefits: Air Quality-Related Equity Implications of US Decarbonization Policy
Emissions of greenhouse gases (GHG) that contribute to climate change are often associated with emissions of air pollutants that react to form fine particulate matter (PM2.5), which is a significant cause of premature mortality and disproportionally harms people of color and low-income populations …

Measuring Methane Emissions in the Urban Environment
… column dry air mole fractions of CH4 and other greenhouse gases (GHG). This network was expanded to five semi-permanent observatory sites and operated to measure emissions coming from the GTA. In order to confirm, quantify, and discover new sources of CH4 emissions in the GTA, a bicycle-based …

Carbon management and scenario planning at the landscape scale with GIS
… of increasing atmospheric concentrations of greenhouse gases (GHG) such as carbon dioxide. Responses to the threat of future climate change are both adaptations to new climate conditions, and mitigation of the magnitude of change. Mitigation can be achieved both through reducing emissions of …

Fossil fuel impact of buildings electrification in New York City
<p>New York City's commitment to reduce Greenhouse Gases (GHG) emissions 80% by 2050 (80X50) requires a deep citywide conversion from fuel combustion systems to more efficient technologies, such as air-source heat pumps. Moreover, this challenging goal relies also on a much cleaner grid with the …

Methane and carbon dioxide cycling in soils of the Harvard Forest
… et al., 2016) and can act as a net source of greenhouse gases (GHG). However, if organic material accumulates in soils faster than it is converted to CO2 by cellular respiration, soil becomes a smaller GHG source and even has the potential to become a GHG sink. Not much is known about factors …

Analysis of future carbon tax scenarios for South African gold mines
… 2019, and it places a price on the emissions of greenhouse gases (GHG). The second phase of the carbon tax will be implemented in 2023. Presently, there is uncertainty regarding the changes that will be made to tax policy during this review. This is especially problematic since GHG emissions …
