Global warming potential (GWP) is a measure of how much heat a greenhouse gas traps in the atmosphere up to a specific time horizon, relative to carbon dioxide. It compares the amount of heat trapped by a certain mass of the gas in question to the amount of heat trapped by a similar mass of carbon dioxide and is expressed as a factor of carbon dioxide.

The edge required by renewable technologies is provided by a simplification of the energy supply train. This simplification consists in no longer eating animals. Animals have upside-down energy returned on energy invested values (EROIs), with up to 30 times as much energy having to be put into raising them as we get out of them through eating them or their products. At one time, when our fossil fuels sported extraordinarily high EROIs—100:1 in some cases—we could afford to take this sort of hit on our food-based energy supply. Now, however, we can no longer afford to do so. Moreover, the results of this grossly inefficient energy exchange are rising greenhouse gas emissions. By no longer eating meat, we can reduce greenhouse gas emissions by roughly 14%. Importantly, much of this reduction will be in methane and nitrous dioxide, which have very high global warming potential relative to carbon dioxide.

Mitigation Measures

Abstract The global warming potential GWPgas(H) relates radiative forcing of a single pulse emission of a greenhouse gas, the absolute global warming potential AGWPgas(H), to the respective radiative forcing of carbon dioxide over a defined time horizon H. Mitigation measures targeting short-lived climate forcers (SLCFs) or reversible measures need to be applied permanently to be effective in the long run, but cost effectiveness for a permanent application of a measure differs from a single application. We propose a concept for an absolute global warming potential of permanent yearly pulses AGWP’gas(H), and several options for alternative indices to replace or complement the GWP: For the GWPgas(H/H) and the GWPcgas(H/H) we keep the AGWPCO2(H) in the denominator, which allows the direct comparison with conventional estimates, while for the GWP’gas(H) we define a new metric replacing the denominator by the AGWP’CO2(H). Different cost-effectiveness indicators can be defined respectively. We demonstrate the concept on the example of typical greenhouse gases emitted or removed by the agricultural sector: methane, nitrous oxide and carbon dioxide, fossil and stored as soil carbon. We show that, compared to GWP-based cost-effectiveness analysis, measures targeting soil carbon are discouraged relative to measures targeting methane, nitrous oxide and fossil carbon dioxide.

The Impact

Abstract. This paper presents a simple model to describe the impact on global warming of methane (natural gas) when used for energy production. The model is used to estimate the near-term effect of energy policies based on natural gas as a bridge fuel. The results make it clear that the commonly employed global warming potential of methane with a 100-year time horizon has the following problems: 1: it produces misleading results; 2: is inconsistent with meaningful tracking of greenhouse gas emissions; and 3: is incompatible with the precautionary principle.

Greenhouse Emissions

Natural gas well blowouts can release a large amount of methane along with other greenhouse gases. According to the Intergovernmental Panel on Climate Change, the global warming potential (GWP) of fossil methane is 30 times higher than that of carbon dioxide in a 100-year time horizon. Here, we show that combustion can be used as a means to significantly reduce the global warming effect of greenhouse emissions from gas well blowouts: up to 90 percent of the effect can be eliminated by combusting the released natural gas. The 2015 Aliso Canyon storage well blowout is used as an example.

The Impact

Abstract In general, we can call the carbon footprint as emissions of gases that affect the Earth’s climate, while being used by humans. The impact of construction, building materials, structures, or the overall life cycle of a building on the environment is great. Sustainable architecture is gaining more prominence, using reduced carbon footprint. Today’s construction industry is increasingly moving towards sustainable construction, which is constantly being formed. The great weather fluctuations that take place from day to day are forcing us to reduce our greenhouse gas emissions. The global warming potential GWP (global warming potential) caused by these greenhouse gas emissions is increased to carbon dioxide CO2 and expressed as carbon dioxide equivalent CO2eq. Using GWP we can determine the carbon footprint of a product. The aim of this paper is to change the three compositions of the perimeter walls using LCA analysis (life cycle assessment) and to choose the composition that has the best carbon footprint and is therefore more advantageous. The need for a sustainable built environment is urgent due to its positive impact on the environment.
