This article presents a green roof cost-benefit analysis (CBA). Green roofs are roofs which are partially or completely covered by vegetation. We discuss the benefits and costs of light self-sustaining vegetated roofs. The benefits of the ecosystem services (ES) provided by green roofs can be classified into private and public benefits. We apply the selected valuation methods first in Helsinki, Finland and subsequently explain how results can be transferred to other urban locations. Past research and this study show that private benefits are usually not high enough to justify the expensive investment for a private decision maker. However, when the public benefits are added to the private benefits, social benefits are higher than the costs of green roofs in most cases.Past research quantified most types of the benefits, excluding scenic and biodiversity benefits. Scenic benefits denote the intangible benefits that people derive from the presence of green space, including at least aesthetic and psychological ones. In this article, special emphasis is placed on the valuation of the scenic benefits; these are among the most challenging benefits to valuate in monetary terms. We employ hedonic pricing theory, implemented via spatial regression models, and green roof implementation scenarios in order to estimate the aggregate willingness to pay for a “unit” of green roof. The results show that the scenic benefits can be a significant attribute in cost-benefit calculations. Yet, the amount of benefits strongly depends on the green roof design.

Green roofs respond to a need of today’s society to orient its development towards sustainability. Architecture and urban planning, as builders of the modern city, play a crucial role in the search for a balance between social, environmental and economic growth. Green roofs imply recognized benefits in all three fields, but a study of the economic viability of these solutions is necessary, especially in the field of rehabilitation with tighter budgets. Through a cost-benefit analysis throughout its useful life, it is intended to avoid that the initial construction cost of a green roof, or any sustainable construction, could discourage users, helping them to understand its global dimension from an economic point of view.

Is It Worth the Costs? Using Cost-Benefit Analysis to Minimize the Collateral Consequences of Convictions

Public Benefits

The collateral consequences of criminal convictions are costly for convicted individuals, victims, taxpayers, and society as a whole. Many of these costs are above and beyond the initial sentence, and they have far-reaching consequences. People with criminal records often struggle to find jobs, attend college, receive public benefits, and vote. Many reoffend, which places a high-priced burden on the victims, the surrounding community, and the taxpayers who fund the justice system. Fortunately, programs and policies can address these effects. But debates surrounding these programs and policies are often dominated by one of two perspectives: either a focus on the anticipated benefits or a primary concern with costs. Cost-benefit analysis can be an enormously helpful tool for policymakers when assessing the merits of a program and determining whether to invest scarce resources in criminal justice programs and policies.

The current practise of cost-benefit analysis inWestern countries consists of a collection of various incompatible ideas and methodologies to obtain replicable numbers for the costs and benefits of major public spending plans. This paper describes the main elements of the dominant methodology, which combines consumer and producer surplus, price-taking, government-inputs-as-outputs, hedonic pricing of externalities, and the issue-specific use of partial or general equilibrium thinking. The paper then discusses how that methodology can be augmented and partially replaced by looking at how prospective policies would change the total number of WELLBYs (life satisfaction-adjusted years of life) of the population. The ability of the WELLBY methodology to address complex externalities is illustrated by the Easterlin Discount, which is a proposed reduction factor of 75% on all estimates of private consumption benefits to offset the envy caused in others.
