Measuring CO2 emissions induced by online and brick-and-mortar retailing

We develop a method for empirically measuring the difference in carbon footprint between traditional and online retailing (“e-tailing”) from entry point to a geographical area to consumer residence. The method only requires data on the locations of brick-and-mortar stores, online delivery points, and residences of the region’s population, and on the goods transportation networks in the studied region. Such data are readily available in most countries, so the method is not country or region specific. The method has been evaluated using data from the Dalecarlia region in Sweden, and is shown to be robust to all assumptions made. In our empirical example, the results indicate that the average distance from consumer residence to a brick-and-mortar retailer is 48.54 km in the studied region, while the average distance to an online delivery point is 6.7 km. The results also indicate that e-tailing increases the average distance traveled from the regional entry point to the delivery point from 47.15 km for a brick-and-mortar store to 122.75 km for the online delivery points. However, as professional carriers transport the products in bulk to stores or online delivery points, which is more efficient than consumers’ transporting the products to their residences, the results indicate that consumers switching from traditional to e-tailing on average reduce their CO2 footprints by 84% when buying standard consumer electronics products.

Synsättet på förnyelsebara elkällor inom fastighetsbranschen

För mellan 40-50 år sedan så byggdes en miljon bostäder i Sverige. Idag har arbetet påbörjats med att renovera och restorera dessa bostäder, i samband med dessa åtgärder så görs även många åtgärder för att minska energianvändningen. Syftet med detta arbete var att ta reda på vad som var det mest ekonomiska valet av olika gröna elkällor. Även fastighetsägarnas egna tankar och uppfattningar ställs i relation till slutsatserna vid beräkningarna för att få en uppfattning om det stämmer överens. För att arbetet inte skulle bli för stort och krävande så gjordes dessa avgränsningar:  För att tiden skulle räcka till så avgränsades arbetet till Dalaregionen.  Arbetet har dessutom avgränsats till att bara undersöka ekonomin vid valet av de olika gröna elkällorna. Genom två olika undersökningar med mentometerknappar så kunde resultatet om fastighetsägarnas egna tankar och uppfattningar redovisas och analyseras. Vidare kunde fastighetsägarnas tankar och uppfattningar jämföras med beräkningarna och dessa slutsatser kunde då dras: Slutsatser:  Vindkraft var ej lönsam med dagens elpriser.  Av fastighetsbolag kunde det ses att deltagarna trodde olika på vad som gav bäst lönsamhet mellan vindkraft, solel eller grön el.

Residential planning, driver mobility and CO2 emission

The literature on residences and citizens’ transports has focused on either reforming traffic managing in response to residential relocation or post-evaluation of urban planning policies or the evolution of the urban spatial form. In a city there are hotspots that attract the citizens and most of the transportation in the city arises as the citizens’ movement between their residence and the hotspots. Little scholarly attention has been devoted to the possibility to minimize citizens’ transportation in the city by the urban planning of residential areas. In this paper we propose a method to evaluate the environmental impact (in terms of CO2-emissions) of urban plans of residential areas. The method is illustrated in a Swedish case of a midsize city which is presently preoccupied with urban planning of new residential areas in response to substantial population growth due to immigration. The residential plans aims to increase the compactness and residential density in the current center and sub centers leads to less CO2 emissions compare to urban expansion to the edge of the city. The plans of concentrated apartment buildings are more effective in meeting residential needs and mitigating CO2 emissions than dispersed single-family houses.
