INTRODUCTION In recent years, Houston has made great strides in green building, moving into the top ten nationally on both LEED certified and Energy Star rated structures. At the same time, fewer steps have been taken to address transportation, which accounts for one third of U.S. greenhouse gas emissions. 3 To achieve greater sustainability, architects, planners, and developers must take the space between buildings into greater account. As in other metropolitan areas, Houston's commercial developers and property owners are continuing to embrace green building standards, particularly the U.S. Green Building Council's Leadership in Energy and Environmental Design (LEED) standard for new construction. As a result, new offices, schools, institutions, and commercial buildings are increasingly efficient, incorporating a full array of technologies to minimize energy use and greenhouse gas emissions. These are major steps in the right direction, but we can and must do more. Individuals spend only part of their day in any given home, office, school, or other facility. They must also travel between other locations. According to the U.S. Environmental Protection Agency, in 2009, approximately one-third of GHG emissions came from buildings and another one-third came from transportation. If we are to reduce total GHG emissions, it will not be enough to address only buildings. The (lack of) proximity of these daily destinations to one another is a significant driver of the energy consumption and emissions of travel. Further, the quality of the public infrastructure between destinations directly affects which travel modes are available. Destinations that are well-connected by wide sidewalks, bike lanes, or transit—complete streets—are likely to be reached on foot, bike, or transit. Distances that are connected only by auto-oriented roads or highways are likely to be traversed in cars. LEED for New Construction offers 17 (out of 110) points that are related to location of a building or the transportation options serving it. 4 However, none of these points is mandatory and in many cases they can be earned too easily. For example, points are available if there is any bus or other transit stop within 1/4 mile of a project, without regard for the frequency that buses stop there or whether the connectivity that would allow someone to get from the stop to the project site exists. In order to create greener buildings, it behooves developers and others making site-selection decisions to locate new buildings in or near existing activity centers, to take advantage of proximity to other destinations, and to help enable transit service, which works best where there's density. Getting the location right is especially important for new public facilities, including civic buildings, health clinics, schools, community and senior centers, etc. Second, it behooves owners of existing buildings and local jurisdictions to work together to retrofit streets (in the same way one might retrofit an older building) to make them complete, adding safe and convenient facilities for pedestrians and cyclists. By increasing density and completing street infrastructure, we can reinforce existing locations into livable centers, increasing travel options and reducing auto dependence.

The British Columbia Institute of Technology (BCIT) is Canada's premier polytechnic. In 2008, BCIT partnered with its local electricity utility to hire a full-time energy manager. The following year, BCIT's School of Construction and the Environment initiated a campus-as-living-lab of sustainability project called Factor Four in the seven buildings it occupies on BCIT's main campus in Burnaby. The purpose was to explore whether a four-fold (75%) reduction in materials and energy use could be achieved without compromising service levels. By 2016, the project achieved a 50% reduction in energy use and associated greenhouse gas emissions. Factor Four attracted over four million dollars in funding, engaged over 250 students from 12 educational programs, and produced over $200,000 savings annually. In 2017, BCIT set an ambitious target to reduce its annual greenhouse gas emissions 33% below 2007 levels by 2023, and 80% by 2050, across all five of its campuses. BCIT’s ultimate goal is to become both greenhouse gas neutral and a net energy producer. By setting ambitious targets and systematically implementing energy efficiency improvements, utilizing waste-heat exchange, fuel switching, and developing on-site renewable energy, BCIT is on track to achieving its energy management and climate change goals.

<p>The Earth’s population of seven billion consume varying amounts of planetary resources with varying impacts on the environment.  We combine the analytical tools offered by the socio-ecological metabolism and class theory and propose a novel social stratification theory to identify the differences and hot spots in individual resource and energy use. The theory is applied to German society and we use per capita greenhouse gas emissions as a proxy for resource and energy use. We use socio-metabolic profiles of individuals from an economic, social and cultural perspective to investigate resource intensive lifestyles. The results show large disparities and inequalities in emission patterns in German society. For example, the greenhouse gas emissions in the lowest and highest emission classes can differ by a magnitude of ten. Income, education, age, gender and regional differences (FRG vs. GDR) result in distinct emission profiles. Class differentiation is also noted as economic, cultural and social factors influence individual carbon footprints. We also analyze the role of digital technologies, regarding resource and energy consumption, as a proxy for cultural capital. Highlighting inequalities within societies is a step towards downscaling carbon emission reduction targets that are key to avoid transgressing climate change planetary boundary. We discuss the results in the context of climate policy implications as well as behavioral changes that are needed to meet climate policy objectives.</p>
