Effects are measured in terms of equivalency to the toxic effects of a benchmark environmental pollutant or in terms of comparative toxic units (CTUe) when calculated using the USEtox LCIA method. Endpoint impact An effect on human health, ecosystem quality, or resource availability directly experienced by a person or organism. Examples of endpoint impacts commonly measured in LCA studies are human health effects measured in disability adjusted life years, ecosystem quality effects measured in partially disappeared species over an area-year, or economic effects measured as the increased cost associated with extracting scarce resources. Eutrophication The potential of nutrient releases to cause harmful acceleration of Potential biological productivity in an ecosystem. Calculated at the midpoint level in terms of benchmark nutrient pollutants such as nitrogen or phosphate.

  • Taking a Life Cycle Approach to Automotive Environmental Policy
    Taking a Life Cycle Approach to Automotive Environmental Policy SUMMARY Policies with the goal of reducing climate change impacts from cars focus on reducing tailpipe emissions. While automakers can respond by improving fuel economy with lightweight materials, this can lead to an increase in carbon emissions over the life of a vehicle. Taking a life cycle approach to automotive environmental policy—from production to disposal—helps avoid such unintended consequences. Tailpipe Mitigation is Not Enough Most climate impacts from internal combustion vehicles come from tailpipe carbon dioxide (CO2) emissions. The other life cycle stages, which include vehicle production, fuel production, and vehicle disposal, have much lower greenhouse gas (GHG) emissions. Understandably, therefore legislators focus on curbing tailpipe CO2 emissions and increasing fuel economy. However, automotive climate policy with an exclusive focus on tailpipe emissions opens the door to unintended consequences. This is equally true for vehicles that use biofuels, electric power trains, or light-weight materials to increase fuel economy. As use phase emissions are minimized, Production phase share of emissions in the total life cycle increases significantly. Critics of biofuels contend that they can cause, directly or indirectly, more GHG emissions than they avoid. Sceptics of electromobility argue that the GHG emissions of producing electric vehicles—and the electricity to drive them—can outweigh their lack of tailpipe emissions. The production of light-weight materials is typically GHG-intensive, so their widespread use would significantly increase the climate change impact of vehicle production. Good environmental policy aimed at reducing climate impact from vehicles therefore needs to consider these “upstream emissions,” which could severely compromise or even negate their climate change mitigation goals.

  • LCT, LCA and Transitioning to a Circular Economy | July 2020 | LCANZ 1 LCT, LCA and CE at a Glance
    July 2020 This mapping process instinctively uses a LCT approach. However, it is important to note that the CE scope is typically broader than a single product line. LCT, LCA and In practice, this means aligning materials to either ‘biological’ or ‘technical’ cycles (see diagram, pg 2), such as developing and scaling reusable models or transitioning utilising a waste stream as an input into the manufacturing process. Design for effective re-use, recycling or composting at the end-of-life should be core to product or service development, including to a Circular consideration taken to maintain material quality and avoid ‘downcycling’. Mandatory product stewardship schemes proposed in New Zealand will benefit from both CE and LCA input at the design phase to help Economy deliver successful outcomes.

Faced with this background, circular economy (CE) and its industrial ecology (IE) pillar seem to be an efcient way to achieve sustainable development within the industrial sector. IE consists of optimizing the networking among industries by using energy and material exchange, which are generated from by-products and waste stocks. It aims to improve the environmental potentialities of integrated clusters called eco-industrial parks (EIPs). Policy in the European Union countries and in French territories has positively infuenced such EIP implementation by the establishment of a set of measures to develop the industrial symbiosis performances.
