The recent publication of Wal-Mart's report on its sustainability efforts has the rare quality of being genuinely impressive. Dramatic goals and powerful follow-through have made for a completely transformed company since the retail giant announced its plan in 2005.

Since 2010, they've eliminated 120,000 metric tons of emissions, saved some $231 million through recycling programs, and doubled their supply of locally sourced produce. From sea to shining sea Wal-Mart has overseen everything from solar panel installations to waste management programs that have prevented over 80% of its trash from reaching the landfill.

Led by sustainability executive Lee Scott, it's clear that Wal-Mart has made fiscally responsible as well as meaningful change to its operations - which is good news no matter how you slice it.

The inevitable 'but' comes when you examine the broader impact of Wal-Mart's effects on the environment and the culture at large - effects that cannot be easily internalized. The simple hard truth is that the pace of consumption by Wal-Mart and its customers is currently unsustainable, and won't cease to be so until renewable energy sources are in place.

Currently, Wal-Mart consumes renewable energy more than its competitors - about 20% - but that's as far as it can go without outside help.

Perhaps it's time that the government and businesses alike took note of its trend-setting industry partners and actively fostered a healthy environment for sustainability.

Elon Musk's Boring Co. planning wider tunnels for freight

Elon Musk’s tunnelling firm plans underground freight tunnels with shipping containers moved on “battery-powered freight carriers”, according to reports

Elon Musk’s drilling outfit The Boring Company could be shifting its focus towards subterranean freight and logistics solutions, according to reports. 

A Boring Co. pitch deck seen and shared by Bloomberg depicts plans to construct wider tunnels designed to accommodate shipping containers. 

Founded by Tesla CEO Musk in 2016, the company initially stated its mission was to offer safer, faster point-to-point transport for people, particularly in cities plagued by traffic congestion. It also planned longer tunnels to ferry passengers between popular destinations across the US. 

The Boring Co. completed its first commercial project earlier this year in April. The 1.7m tunnel system is designed to move professionals between convention centres in Las Vegas using Tesla EVs. It says the Las Vegas Convention Centre Loop can cut travel time between venues from 45 minutes to just two. 


Boring Co.'s new freight tunnels

The Boring Co.'s new tunnel designs would allow freight to be transported on purpose built platforms, labelled as “battery-powered freight carriers”. The document shows that, though the containers could technically fit within its current 12-foot tunnels, wider tunnels would be more efficient. Designs for a new tunnel, 21 feet in diameter, show that they can comfortably accommodate two containers side-by-side, with a one-foot gap between them.

The Boring Co.’s new drilling machine, dubbed Prufrock, can tunnel at a rate of one mile per week, which is six times faster than its previous machine, and is designed to ‘porpoise’ - mimicking the marine animal by ‘diving’ below ground and reemerging once the tunnel is complete. 

Tesla’s supply chain woes 

Tesla is facing its own supply chain and logistic issues. The EV manufacturer has raised the price of its vehicles, with CEO Musk confirming the incremental hike was a result of “major supply chain pressure”. Musk replied to a disgruntled Twitter user, confused as to why prices were rising while features were being removed from the cars, saying the “raw materials especially” were a big issue.

Car manufacturing continues to be one of the industries hit hardest by a global shortage in semiconductor chips. While China’s chip manufacturing levels hit an all-time high in May, and the US is proposing a 25% tax credit for chip manufacturers, demand still outstrips supply. Automakers including Volkswagen and Audi have again said they expect reduced vehicle output in the next quarter due to a lack of semiconductors, with more factory downtime likely
