Ecodriving and Carbon Footprinting: Understanding How Public Education Can Reduce Greenhouse Gas Emissions and Fuel Use

Ecodriving is a collection of changes to driving behavior and vehicle maintenance designed to impact fuel consumption and greenhouse gas (GHG) emissions in existing vehicles. Because of its promise to improve fuel economy within the existing fleet, ecodriving has gained increased attention in North America. One strategy to improve ecodriving is through public education with information on how to ecodrive. This report provides a review and study of ecodriving from several angles. The report offers a literature review of previous work and programs in ecodriving across the world. In addition, researchers completed interviews with experts in the field of public relations and public message campaigns to ascertain best practices for public campaigns. Further, the study also completed a set of focus groups evaluating consumer response to a series of websites that displayed ecodriving information. Finally, researchers conducted a set of surveys, including a controlled stated-response study conducted with approximately 100 University of California, Berkeley faculty, staff, and students, assessing the effectiveness of static ecodriving web-based information as well as an intercept clipboard survey in the San Francisco Bay Area. The stated-response study consisted of a comparison of the experimental and control groups. It found that exposure to ecodriving information influenced people’s driving behavior and some maintenance practices. The experimental group’s distributional shift was statistically significant, particularly for key practices including: lower highway cruising speed, driving behavior adjustment, and proper tire inflation. Within the experimental group (N = 51), fewer respondents significantly changed their maintenance practices (16%) than the majority that altered some driving practices (71%). This suggests intentionally altering driving behavior is easier than planning better maintenance practices. While it was evident that not everyone modifies their behavior as a result of reviewing the ecodriving website, even small shifts in behavior due to inexpensive information dissemination could be deemed cost effective in reducing fuel consumption and emissions

Why carbon footprinting (and carbon labelling) only tells half the story

The UK is a world leader in the use of carbon footprints. The introduction of PAS2050 has legitimised carbon footprinting and manufacturers and retailers have responded by estimating carbon footprints for selected products. In industrial production, where the relationship between inputs and outputs is constant and the process is tightly controlled, carbon footprints tend to be reproducible. However, agricultural production is different, being influenced by biological, geological and climatic variation. Thus, although the use of a single value to represent the carbon burden of a food product is appealing, in practice it can be misleading. This paper discusses the variability associated with carbon footprints of agricultural products and considers the value of carbon labelling. We suggest that carbon footprinting is a useful approach that will assist in the transition to a low carbon society but that current approaches to carbon labelling may not help consumers understand the carbon burden of agricultural products

Carbon footprinting for design education

The use of Carbon Footprinting as a metric for gauging the sustainability of products has gained momentum in the past five to ten years. As such it needs to be introduced to design students studying sustainable design modules, despite the recognised limitations of the approach. Following the completion of the literature review, a teaching package comprising an introductory lecture, the new carbon footprinting tool – ‘Dirty Carbon’ and a practical workshop were developed. The new tool was assessed with design students against an industry leader called ‘Sustainable Minds’. Students (n=42) were provided with contextual information on what a carbon footprinting is by attending the lecture, then taught how to use the two tools and asked to perform a full carbon footprint analysis of a product using both tools within a workshop setting. The outputs from the project showed that Dirty Carbon outperformed the market leader in a teaching context. Further testing through end of semester exams demonstrated that the new teaching package had contributed to a high level of knowledge attainment regarding carbon footprinting

Food Miles, Carbon Footprinting and their potential impact on trade

To obtain market access for NZ food exports to high value developed country markets exporters are having to comply and consider environmental factors such as carbon footprinting. This growth in demand for environmental attributes is shown in the rise of the food miles debate or concept. Food miles is a concept which has gained traction with the popular press arguing that the further food travels the more energy is used and therefore carbons emissions are greater. This paper assesses, using the same methodology, whether this is the case by comparing NZ production shipped to the UK with a UK source. The study found that due to the different production systems even when shipping was accounted for NZ dairy products used half the energy of their UK counterpart and in the case of lamb a quarter of the energy. In the case of apples the NZ source was 10 per cent more energy efficient. In case of onions whilst NZ used slightly more energy in production the energy cost of shipping was less than the cost of storage in the UK making NZ onions more energy efficient overall. The paper then explores other developments in market access to developed markets especially the rise in demand for products to be carbon footprinted and the introduction of carbon labelling. A review of latest methodology in carbon footprinting the PAS from the UK is reviewed and implications for trade assessed.

Carbon Footprinting the Internet

The internet is the world's fastest growing CO2 emitter and tech companies are just beginning to come to terms with their carbon footprints. Using the example of a google search, this article touches on the difficulty of an accurate carbon footprint calculation and raises awareness about the environmental effects of web browsing

Carbon emissions locked - in trade

In recent years there has been a growing concern about the emission trade balance of countries. It is due to the fact that countries with an open economy are active players in the international trade, though trade is not only a major factor in forging a country’s economic structure anymore, but it does contribute to the movement of embodied emissions beyond the country borders. This issue is especially relevant from the carbon accounting policy’s point of view, as it is known that the production-based principle is in effect now in the Kyoto agreement. The study aims at revealing the interdependence of countries on international trade and its environmental impacts, and how the carbon accounting method plays a crucial role in evaluating a country’s environmental performance and its role in the climate mitigation processes. The input-output models are used in the methodology, as they provide an appropriate framework for this kind of environmental accounting; the analysis shows an international comparison of four European countries (Germany, the United Kingdom, the Netherlands, and Hungary) with extended trading activities and carbon emissions. Moving from the production-based approach in the climate policy, to the consumptionperspective principle and allocation [15], it would also help increasing the efficiency of emission reduction targets and the evaluation of the sustainability dimension and its impacts of international trade. The results of the study have shown that there is an importance of distinction between the two emission allocation approaches, both from global and local level point of view

Assessment of CO2 emissions reduction in a distribution warehouse

Building energy use accounts for almost 50% of the total CO2 emissions in the UK. Most of the research has focused on reducing the operational impact of buildings, however in recent years many studies have indicated the significance of embodied energy in different building types. This paper primarily focuses on illustrating the relative importance of operational and embodied energy in a flexible use light distribution warehouse. The building is chosen for the study as it is relatively easy to model and represents many distribution centres and industrial warehouses in Europe. A carbon footprinting study was carried out by conducting an inventory of the major installed materials with potentially significant carbon impact and material substitutions covering the building structure. Ecotect computer simulation program was used to determine the energy consumption for the 25 years design life of the building. This paper evaluates alternative design strategies for the envelope of the building and their effects on the whole life emissions by investigating both embodied and operational implications of changing the envelope characteristics. The results provide an insight to quantify the total amount of CO2 emissions saved through design optimisation by modelling embodied and operational energy
