We use Earth's measured energy imbalance, paleoclimate data, and simple representations of the global carbon cycle and temperature to define emission reductions needed to stabilize climate and avoid potentially disastrous impacts on today's young people, future generations, and nature.

The impact of policies which involve trade - offs between one GHG and another (such as replacing coal with natural gas, which would reduce CO2 but might increase methane emissions) is especially uncertain, since current models of both gases» life - cycles (and thus their relative GWPs) may need to be revised in the future.

Focusing the LCA on three key impacts — direct land use, life cycle greenhouse gas (GHG) emissions, and fossil fuel requirements — the researchers identified PV electricity for battery electric vehicles as the superior sun - to - wheels conversion method.

Tax approximate CO2 emissions from final combustion of biofuels and biomass based strictly on product type without attempting to account for carbon sequestered during growth cycles or emitted during harvesting, distillation or other chemical processing or land - use impacts.

The policy problem is a chain of numbers, each of which can be assigned a clear, unambiguous, unmetaphysical estimated probability distribution: the emissions trajectory, the carbon cycle feedbacks, the climate response, the ocean chemistry response, the ice sheet response, the impacts, these are all quantitative.

Even if the regulation reduces the emissions by coal plants by 15 %, the impact on the total carbon cycle will be 0.03 % of natural emissions.

Riverkeeper retained Synapse to assess the potential impacts to energy reliability and electric power sector air emissions associated with the construction and operation of a closed - cycle cooling system as the «best technology available» (BTA) for the Indian Point nuclear power plant, in order to inform the analysis being conducted by the New York State Department of Environmental Conservation (NYSDEC) under the New York State Environmental Quality Review Act (SEQRA).

Both the type of feedstock and the manner in which it is developed and harvested significantly affect land use and life - cycle global warming emissions impacts of producing power from biomass.

Wind energy is emission - free so that it does not pollute the environment or contribute to climate change — the single biggest threats to wildlife in that climate change can disrupt reproductive cycles, shift ranges, alter hibernation habits, and impact the availability of prey.

Disturbances such as Superstorm Sandy and Hurricane Katrina cause large impacts to the terrestrial carbon cycle, forest tree mortality and CO2 emissions from decomposition, in addition to significant economic impacts.

Energy efficiency and reducing reliance on coal for electricity generation not only reduces emissions of greenhouse gases, but also reduces emissions of fine particles which cause many premature deaths worldwide as well as reducing other health impacts from the coal fuel cycle.

Truly only one negative feedback in the planet's overall carbon cycle can act with sufficient speed and strength to avert catastrophic climate impacts: The dominant carbon - based life form on this planet will have to respond to the already painfully clear impacts of our carbon emissions by slashing those emissions sharply and eventually running the planet on carbon - negative power.

Similarly, an assessment of lithium - ion batteries released by the Swedish Environmental Research Institute last year found GHG emissions from battery production were largely due to the manufacturing process, while mining and refining had a relatively small impact on the life cycle.

Any projection of overall environmental impacts and emissions is complicated by the fact that several major applications retain the bulk of their fluorinated gases during their respective life cycles, resulting in the accumulation of significant stocks that need to be responsibly managed when these applications are eventually decommissioned.

Recent studies with actual data have estimated the impact of cycling on air pollution and carbon dioxide emissions.

Studying the tax code's impact on GHG emissions the panel will necessarily focus heavily on energy, both the life cycles of different energy sources and their uses in different sectors such as electricity generation, transportation, industrial processes, and consumer uses (including in households).

I suppose the battle - lines here are drawn between on the one - hand those who believe in either significant natural feedbacks impacting the carbon cycle as - we - speak or who believe today's mitigation measures are useless, and on the other - hand those who would welcome some signs of a weakening of the accelerating CO2 - rise as this would encourage more mitigation actions (and less hand - wringing) and who consider CO2 emissions reporting is more than «fluff».

Example research papers on the impact of fossil fuel emissions on tropical cyclones, on sea level rise, and on the carbon cycle demonstrate that the conclusions drawn by researchers about their anthropogenic cause derive from circular reasoning.

Like a full life - cycle analysis for judging the impact on net emissions of a switch in energy - generation technologies, a full Earth - system analysis should become the new standard in judging climate - policy proposals.

There is a wide range in the estimated heat - trapping emissions and other environmental impacts from each biofuel over its life cycle (i.e., from farm to finished fuel to use in the vehicle), depending on the feedstock, production process, and model inputs and assumptions.

In terms of greenhouse agents, the main conclusions from the WGI FAR Policymakers Summary are still valid today: (1) «emissions resulting from human activities are substantially increasing the atmospheric concentrations of the greenhouse gases: CO2, CH4, CFCs, N2O»; (2) «some gases are potentially more effective (at greenhouse warming)»; (3) feedbacks between the carbon cycle, ecosystems and atmospheric greenhouse gases in a warmer world will affect CO2 abundances; and (4) GWPs provide a metric for comparing the climatic impact of different greenhouse gases, one that integrates both the radiative influence and biogeochemical cycles.
