Regulation of Air Pollution: Israel

I. IntroductionII. Air Quality StandardsIII. Clean Air Requirements For Industrial FacilitiesIV. Reduction of Vehicular Pollutionv. Reducing Greenhouse GasesVI. Renewable Fuel StandardsIsrael considers a reduction in its reliance on natural gas and its replacement with renewable fuels to be important objectives, both strategically and for environmental reasons. Meeting these goals is expected to reduce the dependence of the state on imports of oil and protect the environment by reducing levels of pollution. The regulation of fuel emissions and policies for the encouragement of renewable fuel sources are based on a variety of laws, regulations, government decisions, and programs. The main legislative instrument for the control of air quality is the Abatement of Nuisances Law 5721-1961. This Law makes it illegal to cause any considerable or unreasonable noise or air pollution, including odors, “if it disturbs or is likely to disturb a person in the vicinity or a passerby.”The Law authorizes the Ministry of Environmental Protection “to issue nuisance removal orders, and, in case of noncompliance, to remove the nuisance and to charge the person responsible with double...Get price

insulating gas: The Truths and Myths of this Greenhouse Gas

Sulfr hexafluoride is damaging to the environment: TRUE. Along with CFCs, HCFCs, HFCs and PFCs, sf 6 is an industrial gas that doesn’t exist naturally in the atmosphere and so impacts the radiation balance, contributing to climate change. gaz sf6 is the energy industry’s “dirty little secret”: FALSE. Sulfr hexafluoride is certainly no secret in the Norwegian energy industry. Its use is highly regulated, and many of its users are working together to share experience and come up with viable alternatives insulating gas is used in wind turbines: TRUE. sf6 gas is used not in the turbine itself, but in the switchgear that controls the current generated by the turbine.
