SOLAR RADIATION MODIFICATION (SRM)

Solar radiation modification refers to the intentional modification of the Earth’s shortwave radiative budget with the aim of reducing warming. Artificial injection of stratospheric aerosols, marine cloud brightening and land surface albedo modification are examples of proposed SRM methods. SRM does not fall within the definitions of mitigation and adaptation (IPCC, 2012b, p. 2). Note […]

SOLVENCY CAPITAL REQUIREMENT (SCR)

The solvency capital requirement is the amount of funds that insurance and reinsurance companies are required to hold under the European Union’s Solvency II directive in order to have a 99.5% confidence they could survive the most extreme expected losses over the course of a year. The SCR incorporates risks such as non-life underwriting, life […]

SOLVENCY II

The European Union’s Solvency II directive came into effect in 2016, putting solvency risk at the heart of a harmonised regulatory framework for insurance firms across EU member states. Solvency II is a far-reaching programme of prudential regulations, which vary in severity depending on the riskiness and diversity of an insurer’s business. Similar to the […]
