EPA memo steers water money to disadvantaged communities

Read the full story from the Associated Press.

The Biden administration issued guidance to states on Tuesday that it said will ensure the country’s largest-ever investment in water infrastructure doesn’t bypass disadvantaged communities that are disproportionately affected by environmental hazards like pollution.

The Environmental Protection Agency’s guidance memo applies to $43 billion in the infrastructure bill for making drinking water cleaner, improving sewage treatment and replacing lead pipes. The agency said the memo helps the Biden Administration meet its goal of addressing environmental needs in communities that often have high rates of poverty and unemployment.

The money will be distributed over five years and boost programs that give states and territories broad discretion in funding water projects — but with some parameters on how the money should be used. For example, the memo said nearly half of the $15 billion for lead pipe replacements must go to disadvantaged communities.

Disinformation, extremism make climate action tougher than it should be: McKenna

With the last vestiges of a three-week occupation gradually clearing out of downtown Ottawa, and at least one key convoy organizer showing up in court wearing an “I [heart] Oil and Gas” hoodie, a former federal environment minister is pointing to parallels between two of the urgent, science-based issues the country faces—the pandemic and the climate emergency.

“On the negative side, we’re seeing the role of disinformation. We see it on climate. We’ve seen it about vaccines,” said Catherine McKenna, who served as environment and climate minister from 2015 to 2019 and took waves of vitriolic abuse for her efforts.

“Folks may be wondering why I’m tweeting up a storm about what’s going on in Ottawa,” she told The Energy Mix in an interview last week. “It’s because I worry about democracy. We’re not going to get climate action unless we have a government that represents the people who are demanding that action.”

How climate change threatens the Winter Olympics’ future – even snowmaking has limits for saving the Games

The Winter Olympics is an adrenaline rush as athletes fly down snow-covered ski slopes, luge tracks and over the ice at breakneck speeds and with grace.

When the first Olympic Winter Games were held in Chamonix, France, in 1924, all 16 events took place outdoors. The athletes relied on natural snow for ski runs and freezing temperatures for ice rinks.

Nearly a century later, in 2022, the world watched skiers race down runs of 100% human-made snow near Beijing. Luge tracks and ski jumps have their own refrigeration, and four of the original events are now held indoors: Figure skaters, speed skaters, curlers and hockey teams all compete in climate-controlled buildings.

Innovation made the 2022 Winter Games possible in Beijing, but snowmaking can go only so far in a warming climate.

As global temperatures rise, what will the Winter Games look like in another century? Will they even be possible?

Former host cities that would be too warm

The average daytime temperature of Winter Games host cities in February has increased steadily since those first events in Chamonix, rising from 33 degrees Fahrenheit (0.4 C) in the 1920s-1950s to 46 F (7.8 C) in the early 21st century.

In a recent study, scientists looked at the venues of 19 past Winter Olympics to see how each might hold up under future climate change.

They found that by midcentury, four former host cities – Chamonix; Sochi, Russia; Grenoble, France; and Garmisch-Partenkirchen, Germany – would no longer have a reliable climate for hosting the Games, even under the United Nations’ best-case scenario for climate change, which assumes the world quickly cuts its greenhouse gas emissions. If the world continues burning fossil fuels at high rates, Squaw Valley, California, and Vancouver, British Columbia, would join that list.

By the 2080s, the scientists found, the climates in 11 of 21 former venues would be too unreliable to host the Winter Olympics’ outdoor events; among them were Turin, Italy; Nagano, Japan; and Innsbruck, Austria.

These venues would all be susceptible to problems associated with snowmaking.

Ideal snowmaking conditions today require a dewpoint temperature – the combination of coldness and humidity – of around 28 F (-2 C) or less. More moisture in the air melts snow and ice at colder temperatures, which affects snow on ski slopes and ice on bobsled, skeleton and luge tracks.

As Colorado snow and sustainability scientists and avid skiers, we’ve been watching the developments and studying the climate impact on the mountains and winter sports we love.

Conditions vary by location and year to year

The Earth’s climate will be warmer overall in the coming decades. Warmer air can mean more precipitation in some areas. It can also mean more winter rain, particularly at lower elevations. Over the globe, snow has been covering less area.

However, local changes vary. For example, in northern Colorado, the amount of snow has decreased since the 1970s, but the decline has mostly been at higher elevations.

A future climate may also be more humid, which affects snowmaking and could affect bobsled, luge and skeleton tracks.

Of the 15 Winter Games sports today, seven are affected by temperature and snow: alpine skiing, biathlon, cross-country skiing, freestyle skiing, Nordic combined, ski jumping and snowboarding. And three are affected by temperature and humidity: bobsled, luge and skeleton.

Technology also changes

Developments in technology have helped the Winter Games adapt to some changes over the past century.

Hockey moved indoors, followed by skating. Luge and bobsled tracks were refrigerated in the 1960s. The Lake Placid Winter Games in 1980 used snowmaking to augment natural snow on the ski slopes.

Today, initiatives are exploring ways to make skiing possible year-round with indoor skiing facilities. Ski Dubai, open since 2005, has five ski runs on a hill the height of a 25-story building inside a resort attached to a shopping mall.

But making snow and keeping it cold requires energy and water – and both become issues in a warming world. Water becomes more scarce in many areas. And energy, if it means more fossil fuel use, further contributes to climate change.

The International Olympic Committee recognizes that the future climate will have a big impact on the Olympics, both winter and summer. It also recognizes the importance of ensuring the adaptations are sustainable.

The Winter Olympics could become limited to more northerly locations, like Calgary, Alberta, or be pushed to higher elevations.

Summer Games are feeling climate pressure, too

The Summer Games also face challenges. Hot temperatures and high humidity can make competing in the summer difficult, but these sports have more flexibility than winter sports.

For example, changing the timing of typical summer events to another season can help alleviate excessive temperatures. The 2022 World Cup, normally a summer event, is scheduled for November so Qatar can host it.

What makes adaptation more difficult for the Winter Games is the necessity of snow or ice for all of the events.

Future depends on responses to climate change

In uncertain times, the Olympics offer a way for the world to come together.

People are thrilled by the athletic feats, like Jean-Claude Killy winning all three Alpine skiing events in 1968, and stories of perseverance, like the 1988 Jamaican bobsled team competing beyond all expectation.

The Winter Games’ outdoor sports may look very different in the future. How different will depend heavily on how countries respond to climate change.

Gen Z And sustainability: The disruption has only just begun

Read the full story in Forbes.

Since Sustainability is a topic on all retailers’ minds, I thought it would be helpful to put the whole subject into perspective with some eye-opening data from a recent report First Insight produced in partnership with the Baker Retailing Center at the Wharton School of the University of Pennsylvania. First Insight published a similarly themed report in early 2020, and the changes in consumer thinking that have transpired in just a few years are nothing short of remarkable. The brands and retailers who begin to integrate these generational preferences now will be the ones best prepared for the future.

Since 2019, as more Gen Zers have matured into young adults, their collective voice has become a greater force within the world at large. This demographic cohort comprises young people born after 1997, meaning that the oldest members of this generation turn 25 this year. Also known as the “Tik Tok” generation, they are profoundly committed to making choices that align with their values. Often these choices put the health of the planet first, and include cutting down on consumption, reducing one’s carbon footprint, supporting small batch producers and local businesses, participating in the circular economy, and purchasing previously owned—not new—items. No generation before them has shown the same widespread commitment to any societal issue since the Boomers were protesting the Vietnam war in the late 1960s/early 1970s. Retailers and brands need to pay close attention, because by 2031, Bank of America predicts that Gen Z’s income will surpass that of their next older generation, Millennials, and they will become “the most disruptive generation ever.”

Three NREL teams win REMADE awards to remake recycling, manufacturing, and more

REMADE aims to make a circular economy happen—and soon. In December 2021, the institute awarded $33.2 million to 23 new research projects. Three of those teams include advanced manufacturing experts from the National Renewable Energy Laboratory (NREL). According to the REMADE Institute, these 23 projects could eliminate carbon emissions equivalent to the annual emissions of more than 5.2 million cars.

For their three projects, NREL researchers will help create a new college-level course, collect better data to understand barriers to recycling, and develop best practices for recycling solar panels.
