Negative-emissions insurance

Focus on negative emissions

The promise of negative emissions.

IN THEIR PERSPECTIVE “The trouble with negative emissions” (14 October, p. 182), K. Anderson and G. Peters assert that negative-emissions technologies are an “unjust and high-stakes gamble.” This characterization would sideline negativeemissions technologies and remove potentially important options from the portfolio for mitigating and ameliorating climate change. As Anderson and Peters acknowl...

Modeling of the Negative Surplus in Insurance

Abstract. An insurance activity model that allows to evaluate the duration of the negative surplus is presented in this paper. Assuming the surplus process as continuing if ruin occurs, we consider how long this process will stay below zero. The compound Poisson continuous time surplus process is used for the model development. Analytical formulas are obtained for estimating the expected value ...

Multivariate negative binomial models for insurance claim counts

It is no longer uncommon these days to find the need in actuarial practice to model claim counts from multiple types of coverage, such as the ratemaking process for bundled insurance contracts. Since di↵erent types of claims are conceivably correlated with each other, the multivariate count regression models that emphasize the dependency among claim types are more helpful for inference and pred...

Negative CO2 emissions via enhanced silicate weathering in coastal environments

Negative emission technologies (NETs) target the removal of carbon dioxide (CO2) from the atmosphere, and are being actively investigated as a strategy to limit global warming to within the 1.5-2°C targets of the 2015 UN climate agreement. Enhanced silicate weathering (ESW) proposes to exploit the natural process of mineral weathering for the removal of CO2 from the atmosphere. Here, we discuss...
