Second-life EV batteries find use in railway crossings

Read the full story at New Atlas.

Eventually the battery packs at the heart of electric cars are going to reach the end of their useful lives, but their story doesn’t necessarily end there. They can still retain enough charge for other applications, such as energy storageboating and even classic car conversions. Now Nissan has found another use for such batteries, replacing lead acid units in emergency power supplies at railroad crossings with second-life Leaf batteries – something the company says was previously unheard of.

Lack of power grids sealed fate for early electric cars

Read the full story from Lund University.

New research shows that insufficient infrastructure was key in American car manufacturers choosing gasoline cars over electric cars in the early 20th century. If electricity grids had spread just 15 or 20 years earlier, a majority of producers would have likely opted for electric cars, according to the study.

More trees mean healthier neighborhoods, and a new map is helping the city of Chicago identify neighborhoods that could benefit from increased investment in street trees.

Health geographer and data scientist Marynia Kolak and a team of fellow University of Chicago researchers recently partnered with Chicago’s Department of Public Health to develop a new advanced mapping tool—one that combines tree data with other metrics related to health outcomes, including air quality, surface temperature and traffic volume.

Decarbonizing your supply chain: Where to begin?

Read the full story at GreenBiz.

Unlike many operational decarbonization challenges, reducing supply chain emissions isn’t simply a matter of financing and applying technological solutions — it’s a matter of building and maintaining relationships. This article describes five actionable steps for decarbonizing supply chains. By following these steps, we suggest organizations can build and maintain positive relationships with their suppliers.

Global EV sales rise 80% in 2021 as automakers including Ford, GM commit to zero emissions: BNEF

Read the full story at Utility Dive.

Electric vehicles (EV), including battery electric and plug-in hybrids, made up 7.2% of global car sales in the first half of 2021, up from 2.6% in 2019 and 4.3% in 2020, according to new data from BloombergNEF. In North America, EVs made up 3% of sales in the first half but industry observers say 5% is possible as second half sales pick up.

“Global momentum towards zero-emissions road transport has accelerated significantly,” BNEF said in a report released Wednesday on the transportation sector prepared for the 2021 United Nations Climate Change Conference (COP26).

News of higher EV sales came alongside a commitment from General Motors, Ford and other automakers for all new car sales to be zero emission by 2040. Governments, including New York and California (but not the United States), also signed the pledge.

Climate change: Mars and PepsiCo offer lessons in decarbonization, call for a ‘redesign’ of supply chains

Read the full story from Yahoo Finance.

With world leaders vowing increased scrutiny over businesses’ climate policies at the UN Climate Change Conference (COP26) and regulators crafting disclosure rules to increase transparency around firms’ climate risk profiles, executives are scrambling to accurately map their carbon footprint.

Companies that have already set detailed, science-based targets describe the practice as a ‘monumental task,’ particularly in efforts to reduce Scope 3 or indirect emissions.

Warming temperatures increasingly alter structure of atmosphere

Read the full story from the National Center for Atmospheric Research.

Climate change is having an increasing impact on the structure of Earth’s atmosphere, a new international study shows. The research draws on decades of observations to quantify that warming temperatures are playing a greater role in pushing up the top of the lowest level of the atmosphere by about 50-60 meters per decade.
