The work included data from a variety of sources, including national emissions inventories kept by the United Nations, global estimates of energy use and direct measurements of atmospheric CO2 concentrations, and involved dozens of authors from institutes around the world.

This work presents direct measurements of methane emissions from multiple sources at onshore natural gas production sites incorporating operational practices that have been adopted or become more prevalent since the 1990s.

As a completely electric vehicle, with no gasoline engine as a range extender (as is found in cars like the Chevrolet Volt), there are no direct emissions, although its overall carbon imprint will depend on how the electricity's generated at its source.

I'm not talking concentration in the atmosphere — rather, annual direct emissions from tailpipes, etc vs other sources (e.g. rotting vegetation, animals breathing).

The «emissions reductions» approach, including cap - and - trade systems and other economic incentive mechanisms as well as direct regulatory controls, will require power plants, cars, and many other GHG sources to become more «efficient» by cutting their discharges.

Also this would seem to indicate that the emission center of highest intensity is not direct back at the source but offset by about 25 % from the angle of incidence.

This bipartisan bill directs the EPA to do a four - phase study that 1) develops a universal definition of black carbon; 2) identifies global black carbon sources and reduction technologies; 3) identifies current and possible international funding opportunities to mitigate black carbon emissions; and 4) identifies opportunities for future research and development.

They compared estimated emissions for shale gas, conventional gas, coal (surface - mined and deep - mined) and diesel oil, taking into account direct emissions of CO2 during combustion, indirect emissions of CO2 necessary to develop and use the energy source and methane emissions, which were converted to equivalent value of CO2 for global warming potential.

Unlike a company's carbon footprint, which focuses only on those processes that are subject to the direct influence of the company, a life cycle assessment also incorporates emissions from sources outside the corporate boundary.

Scope 1: Direct GHG emissions occur from sources that are owned or controlled by the company, for example, emissions from combustion in owned or controlled boilers, furnaces, vehicles, etc.; emissions from chemical production in owned or controlled process equipment.

Emissions factors for each technology were determined through a meta - analysis of multiple sources, accounting for direct and indirect eEmissions factors for each technology were determined through a meta - analysis of multiple sources, accounting for direct and indirect emissionsemissions.

Direct GHG emissions are emissions from sources that are owned or controlled by the reporting entity.

PHEVs can reduce direct emissions at the vehicle tailpipe and indirect emissions at the fuel source when they recharge by electricity produced by a portfolio of efficient combustion, non-emitting or renewable generation.

Net - zero emissions will require carbon capture and storage (CCS) for all fossil fuels and other technologies (e.g., biomass with CCS or direct air capture) for residual emissions from fossil fuel extraction and from other anthropogenic sources such as agriculture.

Methane is an important part of the anthropogenic radiative forcing Methane emissions have a direct GHG effect, and they effect atmospheric chemistry and stratospheric water vapour which have additional impacts natural feedbacks involving methane likely to be important in future — via wetland response to temperature / rain change, atmospheric chemistry and, yes, arctic sources There are large stores of carbon in the Arctic, some stored as hydrates, some potentially convertible to CH4 by anaerobic resporation [from wikianswers: Without oxygen.

The «direct» tax proposals under consideration — taxing emissions at the source, a gas tax, etc. — have a certain logic and efficiency to them and avoid the muddle of derivatives (the dangers of which we can all now see only too well).

Whether GHG Reductions Are Direct or Indirect Direct emission reductions are those that occur at sources (or sinks) that are directly owned or controlled by the project developer, i.e., the entity that will operate the project and receive Climate Reserve Tonnes (CRTs).

And you and I would agree, I'm sure, that if the proper externality taxes and policies on safety (all energy sources, etc), power plant siting, mining, the electric grid, agricultural emissions, etc, were put in place, with maybe some public investments directed toward pre-mass market technologies, etc, then whatever mix of sources develops should be good.

Comprehensive policies directed at reducing greenhouse gas emissions from sources other than energy, for example waste, industrial emissions, fugitives, land - use change, deforestation and agriculture.
