Los Angeles City-Owned Buildings to Go 100% Carbon Free
By Maria Stamas
Los Angeles Mayor Garcetti on Monday committed all new or substantially rehabilitated buildings owned by the City of Los Angeles to be 100 percent carbon free — and to use less carbon-intensive building materials in the process. His executive directive not only has Los Angeles leading by example on ways to reduce building emissions, it breaks new ground.
The announcement follows a growing trend of leading cities, such as Seattle, San Francisco and Pittsburgh, in committing new government building stock to be all-electric or become 100 percent emissions free.
Los Angeles also will become the first local government to adopt the state's Buy Clean California Act, requiring carbon emissions reductions from construction materials, including steel, flat glass and insulation beginning in 2021 for buildings such as fire stations, civic centers and libraries.
This executive directive is the latest step in L.A.'s sustainability efforts.
We also know that City Halls cannot tackle this work alone. Community engagement, both in policy development and implementation, will be essential to success. Housing, energy, workforce development and climate change are topics that involve every Angeleno in every community, and we must bring a diverse set of experiences and visions for the future to these policy discussions.
LA Becomes First CA City to Require Less Carbon in Construction Materials
Tackling the carbon emissions used in the materials for new construction — referred to as embodied carbon — is the next frontier of climate action and particularly important for cities. Without policy interventions, worldwide, new construction in cities will generate 100 gigatons of embodied carbon.
Los Angeles' new directive means the emissions performance of materials will be taken into account when an agency is contracting to buy steel, flat glass and mineral wool (insulation), as well as other products the city may add to the list for its buildings. Cement, as one of the most carbon-intensive of materials, would be a great one to look at next. Fortunately, the Carbon Neutral Cities Alliance will soon be publishing a framework for cities to go further in this space.
LADWP to Prioritize Equitable Access to Clean Energy Programs
Among his many directives, Mayor Garcetti also committed the Los Angeles Department of Water and Power to improve access to its clean energy programs specifically for low-income, affordable housing and multifamily properties. Los Angeles faces dual crises of housing affordability and growing climate change impacts, such as severe wildfires. Funding programs to provide energy efficiency and clean energy for these buildings while reducing utility cost burdens for renters will be a welcome relief.
LADWP has the potential to provide greater incentives to its rental housing customers, and so we expect this directive will accelerate progress toward fully programming the $100 million in energy efficiency funds for renters, which were approved by LADWP's Board in June of 2018.
Joining a New but Growing All-Electric Trend
Los Angeles joins a small, but growing trend of cities leading by example in constructing 100 percent clean energy municipal buildings. Already, the city has 26 all-electric buildings in development, totaling $1 billion in construction and 2 million square feet.
Seattle announced just last month it will be requiring all new or substantially altered City of Seattle buildings to operate without fossil fuels, and by January 2021, it will develop a strategy to eliminate fossil fuel use in existing city buildings.
San Francisco, in that same time period, announced all its new or renovated government buildings will be all-electric, the latest in the city's efforts to combat climate change.
Pittsburgh, too, recently committed its government buildings to become net-zero energy, meaning new buildings and major renovations will be highly efficient and produce as much renewable energy on-site or nearby as needed to offset the remainder of their emissions from heating water and warming or cooling their indoor spaces.
It's exciting to see the leadership exhibited by Los Angeles and other leading cities in this space. Not only are they leading by example, reducing emissions in their multi-billion-dollar building portfolios, but these cities are spurring demand for new technologies and less-carbon intensive materials, supporting workforce development and job creation, and paving the way for efficient, renewable, all-electric buildings across the country.
Already many developers are choosing to go all-electric on their own, and several cities across California are going beyond their own buildings to adopt building codes committing privately-developed new construction to go all-electric as well.
With continued commitment from the city and a robust community engagement process, the executive directives announced will significantly advance L.A.'s efforts to cut carbon emissions from buildings.

Summer and fall are great seasons to enjoy the outdoors. But if you're already spending extra time outside because of the COVID-19 pandemic, you may be out of ideas on how to make fresh-air activities feel special. Here are a few suggestions to keep both adults and children entertained and educated in the months ahead, many of which can be done from the comfort of one's home or backyard.
The coronavirus may linger in the air in crowded indoor spaces, spreading from one person to the next, the World Health Organization acknowledged on Thursday, as The New York Times reported. The announcement came just days after 239 scientists wrote a letter urging the WHO to consider that the novel coronavirus is lingering in indoor spaces and infecting people, as EcoWatch reported.

It is undisputed that vitamin D plays a role everywhere in the body and performs important functions. A severe vitamin D deficiency, which can occur at a level of 12 nanograms per milliliter of blood or less, leads to severe and painful bone deformations known as rickets in infants and young children and osteomalacia in adults. Unfortunately, this is where the scientific consensus ends.
Where Does the Deficiency Begin?<p>Nobody knows exactly how much vitamin D a person actually needs. The question of when a deficiency starts is correspondingly controversial. However, vitamin D is becoming increasingly popular.Not only is the pseudo-scientific literature on the "sun vitamin" experiencing an upswing, but the number of published studies has also increased enormously in recent years. For example, in 2019 <a href="https://academic.oup.com/edrv/article/40/4/1109/5126915" target="_blank">a study found that</a> Vitamin D is responsible for keeping the skeleton functional and is associated with cardiovascular diseases, type 2 diabetes and various types of cancer. <br></p>
An All-Rounder<p>Vitamin D levels in the body rise and fall according to sun exposure. If sufficient UV rays reach the skin, the body is able to produce the vitamin itself. However, the human body only derives an estimated 10 to 20 percent of its daily requirement from food.</p><p>The vitamin D that we synthesize from sunlight or food is not biologically active at first. Before the kidneys can produce the biologically active form of the vitamin, known as calcitriol, and release it into the blood, some metabolic processes must take place beforehand.</p><p>In addition, many organs have receptors to which the precursor of calcitriol binds. Further, this substance is also present in blood.</p><p>From this precursor, the organs then produce calcitriol themselves, which the body then uses for countless other processes in the body. This form of vitamin D thus regulates insulin secretion, inhibits tumor growth, and promotes the formation of red blood cells as well as the survival and activity of macrophages, which are important for the <a href="https://www.mdpi.com/2072-6643/5/7/2502/htm" target="_blank">immune system.</a></p>
Low Vitamin D, Severe COVID-19 Disease?<p>A research study carried out <a href="https://www.sciencedirect.com/science/article/pii/S2352364620300067?via%3Dihub" target="_blank">at the University of Hohenheim</a> has now established a link between vitamin D deficiency, certain previous diseases, and severe cases of COVID-19.</p><p>According to the study, "there is a lot of evidence that several non-communicable diseases (high blood pressure, diabetes, cardiovascular diseases, metabolic syndrome) are associated with low vitamin D plasma levels. These comorbidities, together with the often accompanying vitamin D deficiency, increase the risk of severe COVID-19 events."</p><p>"This statement is completely correct," said Martin Fassnacht, head of endocrinology at the University Hospital of Würzburg. However, he qualifies that it is a pure association, "i.e. a mere observation that these events occur together.</p><p>Dr. Fassnacht is very critical of the hype surrounding vitamin D, but not because he denies the vitamin serves important functions. However, studies on humans have not been able to show that vitamin D has the healing powers many often propagate.</p><p>Fassnacht says, "If you take a closer look, the hopes that the administration of vitamin D has a healing effect have not been confirmed so far."</p>
Association Versus Intervention Studies<p>Many studies on the vitamin are association or observational studies. "By definition, these studies cannot prove the causal relationship, but only point to mere correlations," said Fassnacht. The physician tries to illustrate this with an example:</p><p>"Imagine two groups of 80-year-olds. One group is spry, active and does sports. If you compare them with another group living in nursing homes, the difference in vitamin D levels will be dramatic. Life expectancy would also be extremely different."</p><p>But to try to explain the difference in fitness by vitamin D status alone is far too simplistic. "Vitamin D levels are a good measure of how sick someone is. But not more," says Fassnacht. </p><p>According to Fassnacht, none of the intervention studies carried out to date -- that specifically examined the effect of vitamin D on various diseases -- has been able to confirm the previous association and laboratory studies or the presumed positive effect of vitamin D.</p>
Further Research Is Needed<p>"If a coronavirus infection is suspected, it is therefore absolutely necessary to check the vitamin D status and quickly correct any possible deficit," said the recommendation of the paper published by the University of Hohenheim.</p><p>"Studies are underway to see whether vitamin D helps in COVID-19 infection, but I personally do not believe that this is really the case," says endocrinologist Fassnacht. Nevertheless, he says it is of course useful to carry out these studies.<br></p><p>"I don't want to rule out that there are actually subgroups of people who benefit from an additional vitamin D dose," he says. After all, this has been proven to be the case with a severe deficit.</p><p>In view of the study situation, Fassnacht does not think much of preventive, nationwide vitamin D substitutes. "My belief that the vitamin helps somewhere is very low. But, of course, I can be wrong."</p>
