A Car-Free Zone In Berlin | Earth Wise

By Leave a Comment

The regional parliament in Berlin is considering the creation of a car-free zone in the German capital as a result of a petition from a local advocacy group.  The group – called the People’s Decision for Auto-Free Berlin – collected 50,000 signatures, which was enough to require the Berlin Senate to take up the issue.

The city ban would apply to the space ringed by the S-Bahn train line, which circles the city center.  Known as the Ringbahn, the area enclosed was already established as a low-emission zone in 2008.  It is 34 square miles in area, larger than Manhattan.  The ban would restrict vehicle use to trucks, taxis, emergency vehicles, and limited car-sharing programs.

In Berlin, a combination of regular trains, ample bike lanes, and a robust network of public buses makes getting around without a car more practical than in many other major cities.  In fact, automobiles account for only 17% of trips inside of the Ringbahn.

Even so, there is still a lot of car traffic in the city center.  Advocates for the plan believe it would lead to a city with cleaner air and more livable spaces for its citizens.

If the Berlin Senate rejects the measure, the advocacy group will seek to collect 175,000 signatures, which would force the Senate to consider the matter for a second time.  If it is rejected again, it would automatically go to a referendum in 2023.

In Europe, it appears that the revolution in transportation may not just be one about electric vehicles, but in some places may be toward the removal of vehicles in general.

More Extreme Wildfire Seasons | Earth Wise

By Leave a Comment

According to a new study led by researchers at Stanford University, autumn in California feels more like summer now as a result of climate change, and this hotter and drier weather increases the risk of longer and more dangerous wildfire seasons.

The research team, whose work was recently published in the journal Environmental Research Letters, found that the frequency of extreme fire weather conditions in the fall in California has doubled since the early 1980s.  Average temperatures during the season have increased by more than 2 degrees Fahrenheit, and rainfall has fallen by approximately 30%.  The most pronounced warming has occurred in the late summer and early fall.  That finding means that tinder-dry conditions coincide with the strong “Diablo” and “Santa Ana” winds that are typical in California at this time of year.     

In recent years, these conditions have fed large and fast-moving wildfires across California.  The state’s two largest wildfires, two most destructive wildfires, and the most deadly wildfire all occurred during 2017 and 2018, resulting in more than 150 deaths and $50 billion in damage.

Because summertime has typically been peak fire season, the recent spate of autumn fires is putting a strain on firefighting resources and funding.  The ongoing COVID-19 pandemic could further strain emergency resources.  Since fire-prone regions have historically shared  wildfire-fighting resources throughout the year, the consequences of California’s extended wildfire season could have a global impact.  (For example, California’s recent autumn wildfires have coincided with the beginning of wildfires in Australia). 

The researchers highlight some opportunities to manage the intensifying wildfire risk in California, including limiting the trajectory of global warming in keeping with the targets identified in the United Nations’ Paris agreement.

Lifestyle And Carbon Footprint | Earth Wise

By Leave a Comment

Many studies have shown, to no great surprise, that affluent lifestyles lead to larger carbon footprints. Households in Switzerland enjoy a high standard of living and a team of researchers there has been studying the consumption and travel habits of Swiss citizens to better understand the impact of various factors on carbon footprint. Key factors include household composition and income, and whether the households are in the city or the countryside – even though, in the end, people’s lifestyles do not differ greatly from one environment to another. 

A team of researchers at EPFL’s School of Architecture, Civil and Environmental Engineering analyzed data from Switzerland’s household budget survey for 2008, 2011 and 2014.  They combined that data with an environmentally extended input-output analysis to assess households’ carbon footprints by measuring their direct and indirect emissions.

Overall, households in the countryside have larger carbon footprints than those in the city, mainly because they travel more and use more energy in their homes. But urban households have larger carbon footprints than their rural counterparts when it comes to food, clothing, cultural activities and air travel.  

A household’s composition directly influences its carbon footprint. A two-person household has the largest per-capita carbon footprint, and it falls as the size of the family grows since many of the same resources are shared by more people. 

Income levels play an important role.  People consume without much thought because they can afford to and enjoy doing it. But there is a trend towards people becoming more conscious of their levels of consumption and trying to be more responsible in Switzerland.  Overall consumption has actually declined over the years studied.
