emissions

A tire concept uses 70% sustainable materials—including carbon black derived from a process creating hydrogen gas from natural gas.

So much of the responsibility for CO2 reductions is falling on the auto industry. Should more of it rest on the oil industry?

Given typical driving patterns, there isn't a single gasoline vehicle you can buy today that, on a national basis, promises to be cleaner than an all-electric one.

The NHTSA under President Biden will resume the higher fine schedule for gas-guzzling fleets approved in 2016. Should they be applied retroactively?

Dementia is the latest health issue potentially tied to the fine particulate emissions produced by vehicle tailpipes.

Another study confirms that electric vehicles are cleaner over their lifecycles than cars powered by internal combustion engines.

Tightening rules for plug-in hybrids by 2030 and an ell-electric new-car fleet are part of proposed rules in Europe—but 27 member nations will need to approve.

It doesn't take EVs long to make up for their higher carbon emissions from manufacture, U.S. DOE modeling and analysis helps show.

The global warming emissions advantages of big electric trucks might be seen as even more pronounced next to gasoline models.

If Clean Cars Minnesota is enacted, Minnesota would follow California's stricter emissions rules mandating electric vehicles.

With the NHTSA, it proposes to rescind rules that took away California's authority to set its own emissions framework and to mandate EVs.

Tallow, of the sort that used to go toward making fries, will be used to make fuel that's claimed to be chemically identical to petroleum diesel.

The EPA expressed "concerns" about the process used to create the Trump-era rules that relaxed fuel-efficiency targets.

As tires wear from driving, they shed particles that can be carried far away, contributing to pollution in the ocean and atmosphere.

The Biden EPA chief plans to restore stricter auto-emissions standards—and perhaps lay out targets for going all-electric.

The 2021 Toyota Mirai claims to have better than zero-emissions by filtering the outside air, but it ignores the emissions of hydrogen sourcing.

Airstream is offering carbon offsets as well as pushing ahead with plans for an electric trailer that could make towing more feasible with an EV.

An RMI analysis frames it clearly: In order to make meaningful cuts in CO2, people need to drive less.

Five of the top 10 non-gasoline models with the steepest sales gains in 2019 and 2020 were diesels, according to an industry group.

Although EV sales increased 50%, a massive shift to less-efficient SUVs offset any carbon reduction.
