This old technology getting some fresh attention is a trend investors may not want to miss: Heat pumps. Heat pumps provide both air conditioning and heat — all in one device. Heat pumps could play a viable role in this regard," Muhedini said in a research note last week. The DOE also runs a Residential Cold Climate Heat Pump Technology Challenge , which is partnered with Trane, Carrier, and Johnson Controls, among other leading heat pump makers. In the chemicals sector, companies that produce more eco-friendly refrigerants for heat pumps could one day reap the benefits of recent legislation in the U.S. that will ban next year the production of heat pumps that use refrigerants with high levels of global warming potential.

All of this has given rise to climate adaptation, a sector that aims to mitigate against and adapt to the risks associated with climate change. For James Brennan and Navjit Sagoo, two of the scientists behind climate risk analytics startup Climate X, it is imperative that adaption efforts go hand in hand with those working to curb rising temperatures. Indeed, Bank of America analysts predicted the climate adaptation industry would be worth $2 trillion a year by 2026. Climate X made its calculations based on the UN's Intergovernmental Panel on Climate Change's RCP8.5 scenario, which has been deemed to be a "very high" baseline for emissions. Mike Segar/ReutersAll hands on deckThe need for climate adaptation is clear but often overlooked until an extreme weather event occurs, according to Landesman and Chaudhury.

But there's also a blooming black market in greenhouse gases. HFCs are commonly used in refrigerators and air conditioners, but they're also potent greenhouse gases. There's been a thriving black market for climate-altering refrigerant chemicals since the 1990s, at times as lucrative as selling cocaine. KAMIL KRZACZYNSKI/AFP via Getty ImagesThe black market "comes with the territory" of regulation, Doniger said. At the height of the CFC black market, many cars still used those refrigerants for their air conditioners.

CNN —A California man was arrested and charged Monday with allegedly smuggling potent, planet-heating greenhouse gases from Mexico, marking the first such prosecution in the US, according to a statement from the US Attorney’s Office for the Southern District of California. He is then alleged to have sold them for a profit on sites including Facebook Marketplace and OfferUp. These greenhouse gases are short-lived in the atmosphere, but powerful — some are thousands of times more potent than carbon dioxide in the near-term. “The illegal smuggling of hydrofluorocarbons, a highly potent greenhouse gas, undermines international efforts to combat climate change,” said David M. Uhlmann, the assistant administrator for the EPA’s Office of Enforcement and Compliance Assurance. In 2016, nearly 200 nations including the US agreed to the Kigali Amendment to reduce planet-heating pollution from these greenhouse gases.

On Monday, a California man became the first in the nation to be arrested and charged with smuggling the powerful gases into the United States, a felony offense, according to the United States Attorney’s Office for the Southern District of California. Mr. Hart then posted the refrigerants for sale on OfferUp, Facebook Marketplace and other sites, and sold them for a profit, federal agents say. Mr. Hart pleaded not guilty. He faces charges of conspiracy, importation contrary to law and sale of merchandise imported contrary to law. Attempts to reach lawyers for Mr. Hart were unsuccessful.

But industry experts say governments need to offer incentives for companies to bring sustainable AC technologies to market and scale up. Removing humidity requires cooling air to the point at which water vapour becomes a liquid to be drained. This inability to get rid of humidity without first cooling the air makes conventional ACs less efficient. The company's AC prototype uses these materials to dry out air, aiming to produce fewer emissions than traditional ACs. More than 1 billion people living in warm climates still lack access to cooling, according to nonprofit Sustainable Energy for All.

☆ Scientists said the ozone hole was recovering. That good news was premature, one study claims
▼ + stars: | 2023-11-21 | by ( Angela Dewan | ) edition.cnn.com time to read: +4 min

But in a new study published Tuesday, some scientists claim it may not be recovering at all, and that the hole may even be expanding. In a paper, published by Nature Communications, they found that ozone levels have reduced by 26% since 2004 at the core of the hole in the Antarctic springtime. They used historical data to compare that behavior and changing ozone levels, and to measure signs of ozone recovery. “Altogether, our findings reveal the recent, large ozone holes may not be caused just by CFCs,” Kessenich said. “Those events have been shown to have strongly decreased the ozone hole size,” he said, “so including those events would probably have nullified any long-term negative trend.”

Instead this year’s ozone hole was about average size for the last 20 years, even a bit smaller than 2022’s, according to NASA and the National Oceanic and Atmospheric Administration. From September to mid October, the ozone hole this year averaged 8.9 million square miles (23.1 million square kilometers), which is the 16th largest since satellites started tracking in 1979. It peaked this year at 10 million square miles (26 million square kilometers), about the size of North America. The ozone hole and thinning ozone layer has improved a bit thanks to the 1987 Montreal Protocol, when countries in the world agreed to stop producing many of the chemicals that deplete ozone, Newman said. The ozone hole was at its biggest in 2000 at nearly 11.6 million square miles (29.9 million square kilometers), according to NASA data.

(AP) — The U.S. Environmental Protection Agency on Monday proposed banning the cancer-causing chemical trichloroethylene, which can be found in consumer products including automobile brake cleaners, furniture care and arts and crafts spray coating. “Today, EPA is taking a major step to protect people from exposure to this cancer-causing chemical.”Massachusetts Sen. Edward Markey, who has led the effort to ban TCE, welcomed the move. Political Cartoons View All 1215 Images“With this rule, we can see a future where we will no longer be manufacturing, processing and distributing a chemical known to be deadly,” Markey said. The chemical presents an “unreasonable risk of injury to health or the environment” in 52 of 54 uses in industrial and consumer products, the EPA has found. The 2016 law required the EPA to evaluate chemicals and put in place protections against unreasonable risks.

The Global Cooling Pledge – set to be announced at the upcoming United Nations climate summit, COP28 – represents a tough request given the cooling industry is only expected to grow. The emissions from both the refrigerants and the energy used in cooling now account for about 7% of global greenhouse gas emissions, and are expected to triple by 2050 as temperatures continue to rise. "We need cooling, but it has to become more efficient," UNEP Cool Coalition global coordinator Lily Riahi said. Another 13 commitments outlined in the draft pledge include establishing minimum energy performance standards for air conditioning by 2030, and including cooling emissions in countries' overall climate action plans, called Nationally Determined Contributions. The UNEP estimates that global efforts to tackle cooling emissions could have a significant impact by 2050, avoiding the release of up to 86 billion metric tonnes of carbon dioxide equivalent.

They're “the most potent greenhouse gases known to modern science,” as one research paper put it and they're growing fast. With the Environmental Protection Agency required to phase out one family of the chemicals 85% by 2036, the push is on to develop and spread cleaner alternatives. With more than 200 million gasoline cars in the U.S. alone, Groll said that amounts to approximately 100 million pounds of refrigerant leaking out into the atmosphere each year. The need to minimize refrigerant leaks has spurred a reuse and reclamation industry. ___Associated Press climate and environmental coverage receives support from several private foundations.

Refrigerants used in fridges, freezers and cars change from a fluid to a gas to transport heat away from the place you want cooled. In refrigerators, the refrigerant starts as a liquid and expands into a gas, which forces it to cool down. The refrigerant then flows through condenser coils where it releases its heat out and cools back into a liquid. The cycle starts over when the refrigerant enters the expansion device, where the fluid spreads out, cools, and once again turns into a gas. Methane, the second most important greenhouse gas after carbon dioxide is 28, or 28 times worse.

Climate Alliance and the Biden administration are expected to announce a pledge Thursday to quadruple the number of heat pumps in U.S. homes by 2030, from 4.7 million to 20 million. Heat pumps use little electricity, yet are able to heat and cool buildings. Buildings account for more than 30% of global greenhouse gas emissions. The pledge on heat pumps is a collection of state initiatives to work toward the goal of ramping down emissions to zero by 2050. Alliance governors have pledged to collectively reduce their greenhouse gas emissions by at least 26% by 2025 and at least 50% by 2030, compared to 2005 emission levels.

A startup making air conditioning systems more efficient has just raised a $12.5 million seed round co-led by VC funds At One Ventures and Fifth Wall, which invests in real estate tech. California-based Mojave has developed an air conditioning system that uses 50% less energy and 20% less refrigerant than existing systems, it claims. A heating, ventilation, and air conditioning (HVAC) system's footprint is mainly split between the energy used to control the temperature and what it takes to remove humidity, the research found. The "big breakthrough" was finding a way to cool the desiccant with cool air, Farese said. The startup is tackling the outdoor air system (DOAS) market, which refers to systems that precondition air coming into a building from outside.

Companies Novatek PAO FollowMOSCOW, June 13 (Reuters) - Russian company Novatek (NVTK.MM) said on Tuesday it has developed its own technology to produce large-scale volumes of liquefied natural gas (LNG), a key step in boosting LNG production and raising Russia's global share in the fuel market. The company said it obtained a Russian patent for its proprietary technology called "Arctic Mix" for large-scale natural gas liquefaction using mixed refrigerants. Novatek also said the production process has been developed to implement the company's large-scale projects on gravity-based structures with a production capacity of more than 6 million tonnes per year for one producing line. Russia lacks LNG production technologies following withdrawal of Western companies with their know-how last year over Moscow's actions in Ukraine. "This innovation is an important step towards the localization of liquefaction process trains in alignment with the Company's strategic objective to develop LNG technologies in Russia," Novatek said.

☆ UN says ozone layer slowly healing, hole to mend by 2066
▼ + stars: | 2023-01-09 | by ( The Associated Press | ) www.nbcnews.com time to read: +4 min

Earth’s protective ozone layer is slowly but noticeably healing at a pace that would fully mend the hole over Antarctica in about 43 years, a new United Nations report says. “In the upper stratosphere and in the ozone hole we see things getting better,” said Paul Newman, co-chair of the scientific assessment. Natural weather patterns in the Antarctic also affect ozone hole levels, which peak in the fall. A third generation of those chemicals, called HFC, was banned a few years ago not because it would eat at the ozone layer but because it is a heat-trapping greenhouse gas. The report also warned that efforts to artificially cool the planet by putting aerosols into the atmosphere to reflect the sunlight would thin the ozone layer by as much as 20% in Antarctica.

The emissions were equal to the annual greenhouse gas emissions of more than 59,000 automobiles, according to the EPA’s greenhouse gas equivalency calculator. Under such a scenario Duke Energy would likely have years of low emissions punctuated by a single year of high emissions. While other utilities have participated for decades in a voluntary program with the EPA to reduce SF6 emissions to next to nothing, Duke Energy has not. Brooks said Duke Energy is also targeting its most leaky equipment for faster replacement. The figure is roughly half of 1% of all greenhouse gas emissions worldwide, far smaller than yearly emissions of carbon dioxide, the primary driver of climate change.
