| Summary/Abstract |
Firms around the world need to find ways to continuously reduce their carbon footprint, preferably in ways that are profitable or cost-effective. The opportunities available to them will change over time, as they implement the most profitable ones first and as technology changes. When designing and adjusting their carbon policies, policy-makers need to understand the abatement opportunities firms are facing. We explore this using data collected by CDP (formerly the Carbon Disclosure Project) on 20,920 carbon abatement projects implemented by more than 1400 firms worldwide over 7 years. Using fixed effects regression with energy price controls by country, our results show that the average payback period of implemented carbon emissions reduction projects remained relatively constant from 2010-2016, although there is tentative evidence that the projects are becoming smaller over time. We provide a novel firm-level perspective on carbon emissions reduction activities using data on projects implemented and reported by large, global firms, and discuss how the insights from such firm-level analysis can help inform the design and revision of carbon emissions policies over time.

| Summary/Abstract |
Prior research on adoption of rooftop solar has investigated various economic and psychological factors contributing to or impeding adoption. One psychological factor that has been linked to environmental behavior in other settings, but not yet in the context of rooftop solar, is place attachment, an individual's sense of attachment to their community. Using a survey of over 3700 homeowners in Los Angeles County, we examine the impact of place attachment, relative to that of pro-environmental attitudes, on the decision whether to consider rooftop solar and on the decision whether to adopt it. We find that an otherwise average homeowner with pro-environmental attitudes one unit above the mean is 5.66 percentage points more likely to consider rooftop solar, while the effect of place attachment on consideration is not significant. However, among respondents who consider rooftop solar, an otherwise average homeowner with one unit stronger place attachment is 7.59 percentage points more likely to adopt, while the effect of pro-environmental attitudes on adoption is not significant. Policymakers seeking to encourage adoption of rooftop solar should contemplate leveraging place attachment, and should recognize that different policy mechanisms will be effective for homeowners in general than for those who are already considering.
