Sulfur dioxide (SO 2 ), carbonyl sulfide (OCS), and dimethyl sulfide (DMS) are the dominant surface emissions which contribute to aerosol formation. The team concluded that models miss an important cooling factor if they don’t account for the influence of stratospheric aerosol, or don’t include recent changes in stratospheric aerosol levels.
By including upstream emissions from fuels, GHG emissions from cities exceed those attributed to direct end-use by up to 24% (for Toronto). By including upstream emissions from fuels, the researchers found that GHG emissions attributable to cities exceed those from direct end use by up to 24%. Tonnes CO 2 e/capita.

From Denver smog to jammed mountain highways, Colorado is focusing on transportation to solve congestion, pollution, and climate problems. The first in a series of stories based on RMI analysis of how key US states are deploying real climate solutions. See more at State Climate Scorecards.
The presence of ammonia was first discovered in the upper troposphere in 2016 using the analysis of averaged MIPAS (Michelson Interferometer for Passive Atmospheric Sounding) infrared limb-emission spectra. The emission sources are limited up there. This is important, especially in the relatively clean upper troposphere.

Lilac Solutions has developed a new ion exchange technology to address the challenges face by lithium producers.
Today, we interviewed BMW's electric-car powertrain head, looked at tire swaps for Chevy Bolt EVs, covered some state news on emission limits and charging stations, and offered a PSA on climatechange. All this and more on Green Car Reports. Low-rolling-resistance tires boost electric-car range, but don't do much for handling.

Cassotis said.
And it was the seemingly impossible goal of cutting Berkeley’s greenhouse gas emissions by a full 80% by 2050 – as required by a referendum vote of the Berkeley citizens. Another great model is being set outside of California’s borders by Boulder County, Colorado. No matter the motivation, these people get it.
A new study shows that Plug-ins can both reduce driving expenses and vehicle emissions. With Smart Grid, Plug-In Hybrid Cars Could Have System Benefits Physorg Feb 28, 2007 Xcel Energy announced the results of a six-month study related to plug-in hybrid electric vehicles (PHEVs) and how an increase in their popularity may affect Colorado.
Great news for drivers looking to purchase an electric vehicle in Colorado! On May 11, 2023, Colorado Governor Jared Polis signed House Bill 23-1272 into law. With the upcoming changes being put in place by the new law, Colorado will have the highest state EV tax credit in the country. 4 , and more.

The Creative Greenius says you can now expect a bold United States policy on cutting greenhouse gas emissions, a rapid shift away from carbon-based fuels to renewables and a science-based approach to water policy and other critical resources. Change is but mere weeks away. And again, if that bugs you - so much the better.

Army Corps of Engineers Construction Research Lab Commercial truck and locomotive engine maker Cummins , which has pledged to make all its heavy-duty road and rail vehicles zero-emission by 2050, won a $1 million competitive award to build the H2Rescue, which gets its power from a hydrogen fuel cell that charges its lithium-ion batteries.
Imagine a transportation option that has the fun and flexibility of a bike, is a fraction of the price of a car, can park almost anywhere for free, and produces almost zero climate-changingemissions. Another two-wheeled option for a different type of travel: zero-emission motorcycles. Sounds too good to be true, right?
In what the city is calling a national first, Louisville, Colorado officials held a “ribbon cutting” last Tuesday to celebrate the launch of a new, all-electric residential recycling and waste collection fleet, which is already the city’s streets. Electrek’s Take First off, who even knew they had a Louisville in Colorado!?
Heat pumps can reduce emissions and cut energy costs The DOE is pushing for wider adoption of heat pumps because of their potential to reduce greenhouse gas emissions. It’s generally well known that heat pumps can save money, but there’s a lot of confusion around whether they’re a good idea in all climates,” he says.
With climatechange awareness increasing, gas prices continuing to climb, EV charging stations expanding, and tons of new EV options hitting the market each year, it’s no surprise that electric vehicle purchases are skyrocketing. By offsetting purchase costs, these incentives make emissions-free vehicles attainable for more residents.
In addition to helping the nation meet ambitious carbon-neutral goals, the development and implementation of the proposed technology can help reduce the cost of and emissions from hydrogen production to mitigate the effects of climatechange while creating new jobs and revitalizing our economy.
Adding a metallic film to help reflect radiation skyward makes the emissions—and the cooling—even more effective. One group of researchers at the University of Colorado , Boulder, designed an emitter by embedding a polymer film with microscopic glass beads and coating the back of it with a thin layer of silver.
Doing so, he reasoned, would ensure that the rail corridor didnt exacerbate the areas air quality issues with emissions from diesel engines while also avoiding the high cost of electrifying the line with an overhead catenary system. Thompson: The first one was the development of the first hydrogen mining locomotive, in Colorado.
At issue is the 2012 expiration of the Kyoto Protocol, a binding but effectively unenforceable 1997 treaty that had set greenhouse gas (GHG) emission reduction targets for 40 industrialized countries, referred to as Annex 1 countries, yielding an average GHG reduction of 5.2%
The study shows that Americans face the risk of a 70% increase in unhealthy summertime ozone levels by 2050, assuming continued greenhouse gas emissions with resultant significant warming (IPCC Scenario A2 and RCP (Representative Concentration Pathway) 8.5.). In the other, emissions would be cut by 60-70%. Scenario A2 and RCP 8.5.
As legislation worked its way through Congress, Jenkins’s team provided elected officials, staffers, and stakeholders with a running tally of the possible trade-offs and payoffs in emissions, jobs, and economic growth. The target of reducing emissions by 50 percent by 2030 was established through an executive order in 2021.
