Should We "Go Green"?

August 2007

To benefit society and the environment ethically, or to benefit both policyholders and their stockholders financially, should property-liability insurers join the current global trend to "go green"? If so, how can we be certain that becoming "green" will not someday put our insureds and us in the financial "red"?

by George L. Head, Ph.D.*

Let us focus on standard commercial property-liability policies, setting aside environmental pollution as a sometimes separately covered peril. This means that environmental pollution liability is not an issue here. Instead, a key issue is whether encouraging policyholders to change their products, procedures, and materials to ones that better protect the environment will generate benefits for policyholders and for insurers that will exceed the costs of making these changes.

We need to examine whether insurers' granting lower premiums or discounts to their commercial insureds who adopt environmentally friendly practices will reduce these policyholders' overall costs, increase insurers' underwriting profits, and brighten the insurance industry's still-tarnished public image. We need to consider whether this is the time, and whether environmental responsibility is the issue, for our industry to move forward.

Green Means "Go"

It's easy to want to go green. Reducing toxins and promoting cleaner, less hazardous manufacturing techniques throughout our environments improves the public's health, including that of the employees, the customers, and those who live and work in our neighborhoods. This alone will obviously reduce the health hazards and injury losses an insured faces when handling, storing, or using toxic, caustic materials or breathing in toxic fumes. Therefore, insureds will face fewer health or injury hazards for which they can be sued reducing liability claims.

In short, encouraging insureds to protect the environment also protects insurers' underwriting results for bodily injury, not to mention the property damage claims prevented when spills of hazardous materials are eliminated by switching to earth-friendly substances.

The easiest way insurers can encourage insureds to go green is by offering them premium discounts. These discounts, while still less than the increase in underwriting profits, should be sufficient to motivate insureds to practice greater environmental responsibility. Therefore, these discounts should reward steps that have true environmental benefits, be it in product choice or in the manufacturing process. To illustrate, some insurers are now offering up to 10 percent discounts on their premiums for automobile insureds who choose hybrid cars.

Because going green is such a currently popular trend, it is important that the public recognize that insurers are in tune with their concerns. By addressing the issue of environmental responsibility, insurers demonstrate to their policyholders that they can and will respond to the changing demands of our times. Showing that they are responsive to change, insurers hopefully will earn public and regulatory support well into the future.

Red Means "No Go"

Despite the positives of promoting a cleaner environment and its all-around good effects on our policyholders and the general public, insurers need to keep a realistic perspective on the scope of environmental change. Is there really anything insurers can do, or encourage their policyholders to do, that will have a meaningful impact on climate change or worldwide pollution? To protect their underwriting profits, insurers must not act too hastily.

For example, insurers should not grant premium discounts that unthinkingly encourage insureds to adopt untested new technologies that do not actually generate long-term environmental improvements and therefore do not reduce actual insured losses or—worst of all—actually create new bodily injury or property damage losses. Furthermore, we should not tempt policyholders with premium discounts that encourage them to incur large upfront costs they cannot reasonably expect to recover, especially if insurers find in a year or two that they must cancel their once enticing discounts because something newer, cheaper, and more efficient emerges. To illustrate, ethanol—a fuel once heralded by environmentalists—now has become controversial due to its rising manufacturing costs and the impact it has had on commodity prices, making even the average American's breakfast more expensive.

Being responsive to the public is a fine quality for insurers to have. Policyholders depend on insurers to guide them in practicing responsible risk management, implementing practices that in the long run will benefit both them as individual entities and society as a whole. Our industry's reputation depends on time-tested actuarial principles, not on social fads or political "fashions." Let us not act in haste.

No Time To Be Yellow

"Going green"—done not with "yellow" cowardice but with correct caution—seems to me to be the way for insurers to go. Following the ethical principle of "doing the greatest good for the greatest number," first introduced by Jeremy Bentham and other Utilitarians in the Eighteenth century, and currently followed by today's financial corporate executives, I suggest that insurers consider a seven-step process in deciding whether to grant premium discounts. These discounts would be given to insureds who take carefully defined, environmentally responsible actions that generate net global consequences whose expected present value is positive.

The seven steps for estimating the expected present value of the probable net global consequence (or EPVNGC) for each alternative course of policyholder action are:

  1. Separating consequences into three groups—those which affect (a) an insurer's stockholders, (b) an insurer's policyholders, and (c) members of the public.

  2. For each consequence for each affected group, assigning a positive (plus) value to those consequences which generate a benefit for that group, and a negative (minus) value to those consequences which generate a cost for that group.

  3. Estimating an average dollar value for each benefit/cost for each member of each affected group.

  4. Estimating the number of people in each affected group.

  5. For each consequence for each group, estimating the probability of that consequence actually occurring.

  6. Discounting each cost or benefit by an appropriate factor for the time value of money (such as the federal funds discount rate) for the time interval between when an insured incurs the expenses of taking an environmentally friendly action and when the insured begins receiving the premium discounts and perhaps other financial benefits of that action. (For many such actions, this time interval is essentially zero, making such discounting unnecessary.)

  7. Giving the benefits positive values and the costs negative values as determined in step 2, multiply for each consequence the value in step 3 by the number of people in step 4, multiply again by the probability in step 5, and, if necessary, discount by the value factor in step 6 to arrive at an expected present value of the probable net global consequence (EPVNGC) for each alternative.

Basing their decisions on calculations such as these, insurers should consider giving premium discounts for those policyholder actions that offer significant positive EPVNGC values. It is important that the policyholder actions that earn premium discounts be specified in detail and that policyholders truly take these actions to qualify for these discounts. Moreover, these calculations should guide, not replace, insurers' actuarial and senior management judgment.

This decision process for choosing which, if any, policyholder actions merit premium discounts for "going green" is complex. More importantly, however, it is a decision process that insurers should follow if they wish to be environmentally and ethically responsible to the insureds, stockholders, and society they strive to protect and serve.
