Greenhouse gas emissions are one of the environmental impacts of electricity generation. Measurement of life-cycle greenhouse gas emissions involves calculating the global warming potential (GWP) of energy sources through life-cycle assessment. These are usually sources of only electrical energy but sometimes sources of heat are evaluated. [1]
H 2 O can function as a greenhouse gas because it has a profound infrared absorption spectrum with more and broader absorption bands than CO 2. Its concentration in the atmosphere is limited by air temperature, so that radiative forcing by water vapour increases with global warming (positive feedback). But the GWP definition excludes indirect ...
The SRES scenarios are "baseline" (or "reference") scenarios, which means that they do not take into account any current or future measures to limit greenhouse gas (GHG) emissions (e.g., the Kyoto Protocol to the United Nations Framework Convention on Climate Change). [2]
Carbon accounting (or greenhouse gas accounting) is a framework of methods to measure and track how much greenhouse gas (GHG) an organization emits. [3] It can also be used to track projects or actions to reduce emissions in sectors such as forestry or renewable energy .
Distribution of global greenhouse gas emissions based on type of greenhouse gas (data from 2014) Carbon dioxide (CO 2) is the dominant emitted greenhouse gas, while methane (CH 4) emissions almost have the same short-term impact. [5] Nitrous oxide (N 2 O) and fluorinated gases (F-gases) play a lesser role in comparison.
In the following, a short introduction to input-output analysis and its environmental extension for the calculation of material footprints or RME indicators is provided. . The inter-industry flows within an economy form an n×n matrix Z and the total output of each industry forms an n×1 vecto
Policies for environment, food and rural affairs are delivered in the regions by Defra's executive agencies and delivery bodies, in particular Natural England, the Rural Payments Agency, Animal Health and the Marine Management Organisation. Defra provides grant aid to the following flood and coastal erosion risk management operating authorities:
Here are the conversion factors for those various expressions of wind speed: 1 m/s = 2.237 statute mile/h = 1.944 knots 1 knot = 1.151 statute mile/h = 0.514 m/s 1 statute mile/h = 0.869 knots = 0.447 m/s. Note: 1 statute mile = 5,280 feet = 1,609 meters
