New WHO has issued new Global Air Quality Guidelines (AQGs) that reduce levels of key air pollutants, some of which also contribute to climate change. Since WHO’s last 2005 global update, there has been a marked increase of evidence that shows how air pollution affects different aspects of health. Source: WHO.
Jacobson, professor of civil and environmental engineering at Stanford University, suggests that carbon capture technologies are inefficient and increase air pollution. All sorts of scenarios have been developed under the assumption that carbon capture actually reduces substantial amounts of carbon. —Mark Jacobson.
An international team of scientists, led by NTU Singapore, has linked increased air pollution to an uptick in cases of lung adenocarcinoma (LADC) worldwide. g/m 3 ) increment of black carbon is associated with a 12% increase in LADC incidence globally. Black carbon is a pollutant that is classified as under PM 2.5.

In an open-access report in the journal Environmental Pollution , researchers from UCLA and the University of Chicago estimate that California’s wildfire carbon dioxide equivalent (CO 2 e) emissions from 2020 (~127 mmt CO 2 e ) are approximately two times higher than California’s total greenhouse gas (GHG) emission reductions since 2003.
The study, set in Singapore, suggests that better air quality will bring about climate co-benefits in reducing electricity generation via lower household demand, and thus mitigating carbon emissions. This is important for policymakers when forecasting and influencing future emissions paths in the context of climate change.
California’s air quality programs have forced a reduction in black carbon despite a significant increase in diesel fuel consumption. If California’s efforts in reducing black carbon can be replicated globally, we can slow down global warming in the coming decades by about 15 percent, in addition to protecting people’s lives.
HFCs are considered to be super pollutants because they trap heat in the atmosphere thousands of times more effectively than carbon dioxide, the most prevalent greenhouse gas. Technology exists that makes it possible for new facilities to use refrigerants with very low-GWP today, such as carbon dioxide or ammonia.

The human health benefits associated with improvements in air quality related to the reduction in greenhouse gas emissions improvements can offset 26–1,050% of the cost of US carbon policies, depending upon the type of policy, according to a new study by a team from MIT. Carbon-reduction policies significantly improve air quality.
signed SB 1383 , establishing the nation’s toughest restrictions on super pollutants including black carbon, fluorinated gases and methane. The law is in addition to California’s existing raft of climate legislation. Black carbon, for example, has a global warming potential 3200 times that of CO 2 on a 20-year time scale.
Tenneco is putting its 100-plus years of powertrain expertise in improving vehicle fuel efficiency and reducing emissions to work to explore synthetic fuels (e-fuels) as a viable near-term solution to further maximize the efficiency and minimize the carbon footprint of internal combustion engines (ICE).
Through 2042, EPA estimates the net climate and health benefits of the standards on new gas and existing coal-fired power plants are up to $85 billion. The proposals would also result in cutting tens of thousands of tons of particulate matter (PM 2.5 ), sulfur dioxide, and nitrogen oxide.
General Motors for the first time achieved perfect scores on both climate change data disclosure and performance submitted to CDP , the world’s only global environmental disclosure system. The CDP program enables management of greenhouse gas emissions and risks and opportunities associated with climate change. —GM CEO Mary Barra.
According to the R&D engineer of this project, hydrogen fuel cell construction vehicles have five important advantages: The realization of zero pollution with only water and heat being discharged. The latter is the first hydrogen-powered mixer truck in the world.
The review is the latest product of WHO’s Health in the Green Economy initiative, which is considering available evidence on health impacts from climate mitigation strategies for key economic sectors, as reviewed by the UN’s Intergovernmental Panel on Climate Change. Carlos Dora of WHO’s Department of Public Health and Environment.
However, while greenhouse gases cause warming by trapping heat in the atmosphere, some aerosols can have a cooling effect on the climate because the aerosol particles cause more of the sun’s light to be reflected away from the planet. In many cases, the strongest climate effects of aerosols are felt far from where the aerosols are emitted.
The Administration said that the ambitious target is grounded in analysis of cost-effective carbonpollution reductions achievable under existing law and will keep the United States on a trajectory to achieve deep economy-wide reductions on the order of 80% by 2050.
Now I want to be clear: I am inspired by the Administration’s commitment to phasing out carbon emissions. We do have a climate crisis that needs to be addressed. Heavier vehicles also generate more particulate pollution from tyre wear. The Mustang Mach-E, Volvo XC40 EV, and RAV4 EV are all roughly 33% heavier. Shaffer et al.

The Government of Canada has proposed a pan-Canadian approach to pricing carbon emissions; under the new plan, all Canadian jurisdictions will have carbon pricing in place by 2018. To accomplish this, Canada will set a benchmark for pricing carbon emissions—set at a level that will help Canada meet its greenhouse gas emission targets.
On the first day of a two-day board meeting—the second day of which (Friday 24 March) will consider the Advanced Clean Cars Midterm Review—the California Air Resources Board (ARB) took a number of climate and air quality actions. This plan will also help reduce nitrous oxide, a potent greenhouse gas, and fine particle pollution.

In addition to CARB, the South Coast Air Quality Management District, San Joaquin Valley Air Pollution Control District, and the Sacramento Metro Air Quality Management District provided funding for the project. liter engine.
California will meet its 2030 climate targets more than three decades late, in 2061, and could be more than 100 years late in meeting its 2050 target if the average rate of emissions reductions from the past year hold steady, according to a new study tracking more than a decade of environmental and economic indicators in the state.
The Transportation and Climate Initiative Program (TCI-P) expects to cut greenhouse gas emissions from motor vehicles in the region by an estimated 26% from 2022 to 2032, and generate a total of more than $3 billion dollars over ten years for the participating jurisdictions to invest.
Flameless combustion eliminates all pollutant emissions such as NO x , CO, and PM, and enables the fuel-flexibility that is crucial in creating demand for clean alternative fuels, accelerating the transition to a net-zero carbon economy. Not only can IPG’s technology deliver low-emission, pollutant-free energy on today’s cleaner fuels.
All the participating jurisdictions are members of the Transportation and Climate Initiative (TCI), a regional collaboration of Northeast and Mid-Atlantic states and the District of Columbia that seeks to improve transportation, develop the clean energy economy, and reduce carbon emissions from the transportation sector.
The people whose business model is to wreck the ecology and the climate and profit from it. Even when we reach the limit of our carbon budget, when burning any more oil, coal or gas will push global temperatures beyond 2 degrees celsius, the E&B business model is to harvest more oil so that it can be burned as fuel.
