Methods of measuring an organisations environmental impact

In this instance, with no planning constraints, environmentally conscious designers might look to resource efficiency as a very important value.

So if a process produces only methane as a gas, the LCA will express it as a Carbon Dioxide equivalent. In a way, we've all been used to at least one of its concerns for decades - the conservation of energy has been a focus of the Building Regs since the oil crisis of the s. You get what you measure It is often said 'You get what your measure' which generally holds true. Early on, the NRC recognized that risk assessments could not always be quantitative, and most recently, the NRC emphasized the need for tools for fuller characterizations of cumulative risks, including qualitative ones, that adequately account for the full range of chemical and other stressors, particularly for environmental justice contexts. There is a significant literature on program evaluation, including methods for measuring program performance, including but not limited to Cronbach , Chelimsky , Vedung , Stufflebeam , and Posner On the other hand, almost all policy actions are premised on assumptions about future conditions. The availability of standardized economy-wide input-output coefficients for ready use simplifies this challenge. Most benefit-cost analyses then aggregate the measure of individual net benefits to find a social net benefit and Page 62 Share Cite Suggested Citation:"4 Sustainability Assessment and Management: Process, Tools, and Indicators.

As stated in a previous NRC report a, p. The exposure assessment characterizes elements of the exposure, for example its intensity, frequency, and timing.

It will be important for EPA to establish a systematic way to analyze and quantify alternatives. Although typically not called integrated assessment models, models used for ecosystem-services valuation are also examples that integrate models from multiple disciplines to assess the benefits and costs of alternative policy choices.

However, it is commonly accepted that the more immediately calculable impacts associated with the manufacture, use and disposal of a product are the most important and provide a sound enough base for assessment and comparison.

An LCA looks at the processes involved in the manufacture, use and disposal of any given product LCAs are used to assess all products, not just construction products.

The range of options and the associated social including healthenvironmental, and economic impacts for each option would be presented along with any trade-off analyses that may have been undertaken.

Tools for calculating environmental impact

Most companies now realise that the majority of their impacts sit in their supply chains and they require methods and tools to address this. The roles of the decision makers and the offices contributing expertise will need to be defined and accountability measures should be in place to ensure that the decision maker gives due consideration to the results of the assessment in acting on the subject. In this way, the value of preserving space for occupants effectively 'trumps' the value of resource efficiency and the pollution associated with petro chemicals. Explicit justification: All trade-offs must be accompanied by an explicit justification based on openly identified, context-specific priorities as well as the sustainability decision criteria and the general trade-off rules. In this model, scenarios of socioeconomic development pathways modeled include population growth, fossil fuel use, and food demand. Enabling opportunities into business value Measurement is not just for measurement's sake. However, it is not always possible to approach these questions quantitatively. A wide variety of analytic approaches and tools are used in conducting a risk assessment. Sustainability and the U. This evaluation can be assisted by identifying additional data to better characterize system linkages and responses in indicators other than those that are used to assess goals. Search Measure Measurement is absolutely key to achieving real change. Results should be available as early as is practicable; an assessment may show the need for further information or action on particular issues. Most sustainability indicators are transformations of these data, and the experts involved in the sustainability-indicator efforts have been guided by a need, not only for relevance, but also for practicality. The committee expects that EPA will adopt trade-off rules that are consistent with its existing legal authority and that are based on consideration of trade-off rules used elsewhere.

Integrated assessment models, such as the Global Change Assessment Model GCAMarose in the study of climate change, bringing together global circulation models and economic models to assess the probable benefits and costs of alternative energy- and climate-policy choices Hannam et al.

In the struggle to provide identical overall u-value, the specifier will look to a more 'dimensionally-efficient' product - usually a non-renewable oil-based material such as polyurethane or phenolic foam.

Open process: Proposed compromises and trade-offs must be addressed and justified through processes that include open and effective involvement of all stakeholders.
