While neither idea was ever implemented, both were examples of a “technosignature” or a “technomarker” – a tell-tale indication of past or present technological activity, pointing out the existence of an advanced planetary civilization. Frank is looking at what kind of signature a planet’s technology might leave in its spectra.
We’ve been hearing a lot lately about geoengineering – the various scientific theories and governance ideas that could eventually lead to technological interventions to help cool the planet. In fact, the academic sources that this story describes as “supporters” simply support the goal of further studying geoengineering.
The direct emissions of nitrogen oxides (NO X ) associated with truck pollution exacerbates asthma , and NO X leads to the formation of ozone, which shows clear evidence for reduced lung function and increased mortality. We in Colorado have many days of problematic ozone. California is leading the way, but states are ready to follow.
The types of projects eligible under the CPP range widely, but notably the agency is focused on already proven zero-emission technologies, like electric tractor trucks, tugboats, and cargo handling equipment. The program is squarely focused on zero-emission equipment and projects – combustion technologies are explicitly ineligible.
Several trends today—economic, technological, environmental, and regulatory—are contributing to a transformation of the grid and a parallel evolution in grid reliability tools.
And New Jerseys pollution calamity isnt limited to rivers; ozone pollution is among the worst in the nation. According to the American Lung Association, all counties in New Jersey except for one fell into metropolitan areas that ranked among the twenty-five worst for ozone pollution.
The agency’s air quality modeling indicates that most areas would receive an ozone reduction of less than 0.1 These air quality impacts are minimal compared with the major ozone reductions resulting from the 1998 SIP Call, which resulted in more than 80,000 megawatts of coal capacity being retrofitted with SCRs. ppb by 2025.
A local air district approved a rule requiring warehouses to adopt clean technologies or pay a mitigation fee. These state and federal standards require areas to reach certain ambient concentrations of ozone to be considered in “attainment.” By Joshua T. Bledsoe and Jennifer Garlock. Further Actions.
China is intent on using the Winter Olympics to showcase how they’re at the forefront of implementing low-carbon technologies and thereby tackling climate change. Natural CO2 refrigeration at the ice rinks to 100% renewables-powered venues are just some of the technologies implemented. Photo credit: Beijing 2022. By Anders Lorenzen.

Magic smartphone trees: technology for a circular economy. The book has some positive pictures too, such as one showing the dramatic global reduction in consumption of substances that damage the ozone layer as a result of the Montreal Protocol that was implemented in the 1980s.
After the 2014 shutdown Toledo spent $53 million to install an ozone treatment system at the city’s drinking water plant to safeguard customers from algal toxins, said Andrew McClure, the plant’s administrator. Then there is the ongoing cost of putting that equipment to work. ” .
The Basin does not meet the state or federal ambient air quality standards for ozone and particulate matter, and existing regulations have to date proved insufficient to bring the Basin into compliance. The SCAQMD is the local agency responsible for attaining these clean air standards in the Basin. Facility-Based Mobile Source Measures.

As we explained in our brief, under the federal Clean Air Act, states are required to submit SIPs detailing strategies to come into attainment with federal air quality standards for pollutants like ozone and PM2.5.
Ohio EPA has proposed rules that will require additional Volatile Organic Compound (VOC) and Nitrogen Oxide (NOx) emission controls for certain manufacturing and industrial operations located in the Cincinnati and Cleveland 2015 ozone nonattainment areas. Like VOCs, NOx is a precursor compound which can form ozone.
. -- The Department of Environmental Protection published notice in the February 3 PA Bulletin inviting comments on proposed State Air Pollution Implementation Plan Regional Haze Best Available Retrofit Technology and setting three public hearings March 7 in Norristown, March 7 in Harrisburg, March 7 in Pittsburgh DEP Regional Offices.
Their mitigation recommendations include calls to adopt stronger national and international accountability mechanisms for emissions cuts; policy and financing innovations to promote faster deployment of zero-emissions technologies; and for countries to recognize each other’s climate policies and reflect them in trade measures.
Other examples might include extending battery life, developing better surfactants for hydrocarbon extraction, or making refrigerants that don’t impact on the ozone layer. Does that mean that quantum technology has matured to the point where you don’t need to be a physicist to start a quantum computing company?
EPA states that Metalmark indicates that its initial testing in a small chamber using cigarette smoke resulted in “steep reductions in PM concentrations within 20 minutes, without the creation of byproducts such as ozone or volatile organic compounds.” The technology also removes volatile organic compounds (VOC) carried with smoke.
Read more here. -- The Department of Environmental Protection published notice in the February 24 PA Bulletin the final technical guidance on using trenchless technology to construct natural gas, other pipelines and underground utilities is now available and effective.
The IRA gave us effective tools for cleaning up the power sector through dedicated support for the rapid and widescale deployment of renewable resources and the technologies that support them. Which means the consequences of these polluters unabashedly continuing to pollute aren’t just severe—they’re compounding.
Studies have also shown that fireworks can create a ‘burst’ of ozone formation, also harmful to human health. In the coming year, expect to see a drive towards integrated indoor air management systems and ventilation technologies that focus on preventing the spread of COVID-19 indoors and indoor air contamination.
Today, physics is undergoing a second quantum revolution, with new technology allowing scientists to study ever more weird and wonderful systems. The metals are then captured from the vapour and further refined in an overall process that is described as quicker and cleaner than existing methods.
NOx is a contributor to the formation of summer ozone, and particulate matter smaller than 2.5 EPA regulations require that rebuilt locomotive engines use the latest technology (for that model year locomotive) to reduce emissions. microns has been shown to cause lung damage and cancer.
This post focuses on Ohio EPA’s anticipated regulatory changes to address non-attainment of the 2015 Ozone NAAQS. On January 20, 2021, the Ohio EPA’s Division of Air Pollution Control (DAPC) hosted a “Program Advisory Group” (PAG) meeting via Microsoft Teams to inform interested stakeholders of recent and upcoming DAPC activities.
By replacing older polluting engines and equipment with new technologies, funded projects remove nitrogen oxide, carbon monoxide, particulate matter, and hydrocarbon pollution from the air. “This comprehensive approach to reducing vehicle emissions will help improve Pennsylvanians’ health while also helping to slow climate change.”

Ramamurthy also said the final regulation does not change the substance of how Reasonably Available Control Technology requirements are set for unconventional and conventional oil and gas facilities. It is applied equally to both, not making it a substantively different rulemaking. The Preamble to the revised rulemaking says “.
