Description
This paper recounts a project journey that was taken to explore how replacing plastics with less harmful materials can drive positive environmental impact. The project examined the scope and impacts of plastic pollution attributable to healthcare delivery and the adverse impacts it has on population health. Identifying potential options to replace plastics was accomplished by obtaining access to one of the world’s leading materials databases. This access enabled identification of several alternative materials with documented uses as plastic replacements. Evidence of successes that have been achieved in replacing plastics with less harmful materials was gathered by conducting interviews with international materials experts and senior executives from several different industries. These examples are combined with the research findings on alternative materials to construct a case that taking action can yield financial benefits while doing less harm to people and the planet. The completed project presents a framework that can be followed in future efforts to replace plastics. While the scope of the project focused on the plastic pollution problem from a healthcare perspective, the framework that was created is portable and can be adapted for use in any organization or industry seeking to replace plastics and drive change to create a healthier future.

Description
As arid cities’ water scarcity concerns grow, so does the importance of residential water conservation. Understanding the drivers of participation in water conservation programs can aid policymakers in designing programs that achieve conservation and enrollment targets while achieving cost-effectiveness and distributional goals. In this study I identify and analyze the characteristics that drive participation in the Southern Nevada Water Authority’s Water Smart Landscaping rebate program – a program that pays homeowners to replace their grass lawns with xeric landscaping – and how those characteristics change over time as rebate values and water prices vary.
In order to determine what characteristics influence participation in this program I gathered data from multiple sources. I use a panel dataset of household water consumption that spans 12 years of approximately 300,000 homes. I merged this dataset with home structural characteristics, geographical, and demographic context. I then use these characteristics in a linear probability model, with school enrollment zone fixed effects to determine their influence on a household’s probability of participation. School zones are used to control for unobserved characteristics, such as demographics, which are not at a household level. I then utilize these school zone fixed effects in a 2nd stage regression to decompose these elements and analyze their effect on participation.
I find that a household’s water costs, as reflected in the marginal price faced in the summer and the differential between summer and winter water bills, as well as yard size are primary factors that influence participation. I also show that changes in rebate value and water rates can affect different types of households. There is also evidence to support that neighborhood characteristics affect a household’s likelihood of participating.
