Sulfur hexafluoride - Wikipedia

Sulfur hexafluoride or sulphur hexafluoride, is an extremely potent and persistent greenhouse gas that is primarily utilized as an electrical insulator and arc suppressant. It is inorganic, colorless, odorless, non-flammable, and non-toxic. SF 6 has an octahedral geometry, consisting of six fluorine atoms attached to a central sulfur atom. It is a hypervalent molecule. Typical for a nonpolar gas, SF 6 is poorly soluble in water but quite soluble in nonpolar organic solvents. It has a density ofGet price

Combating climate change through executive compensation

Role of Executive Compensation as A Change AgentIncorporating CO2 Emissions as KPI in Performance Share PlansIntroducing A New Hyper-Long-Term Incentive PlanMeasurement and Target SettingImplementation ConsiderationsCall to ActionThis is where executive compensation can play an important role. Incentive plans have proven to be an effective tool to focus management’s efforts on key priorities and drive desired outcomes. As the saying goes, “what gets measured and rewarded, gets done!” As with all compensation issues, the linkage between CO2 emissions and executive compensation plans should begin with the company’s strategy. More and more companies are beginning to incorporate ESG measures within their short- and long-term incentive plans for senior executives; but there is still room for improvement. Analysis of company public disclosures conducted by Willis Towers Watson shows that while approximately 11% of top 350 European companies have CO2 emissions linked to their incentive plans, only 2% of United States S&P 500 companies have it. If sustainability and environmental goals are front and center of the company’s business strategy, then it should consider linking relevant ESG measures to executive incentiv...Get price
