Sentences with phrase «emissions during driving»

Of course, the goal of a sustainable transport system demands not only zero carbon emissions during driving but also during the production and distribution of the fuel, be it electricity or hydrogen.

Not exact matches

It is also possible to test emissions during real - world driving, using a portable emissions measurement system, though the process is cumbersome.

«A real impact on people» The scientists say their calculations are preliminary and don't account for emissions from forest fires, to which the forest is more vulnerable during drought years, and drought - driven changes in soil decomposition.

During the early 2000s, environmental scientists studying methane emissions noticed something unexpected: the global concentrations of atmospheric methane (CH4)-- which had increased for decades, driven by methane emissions from fossil fuels and agriculture — inexplicably leveled off.

A study recently published in Nature suggests that an extreme global warming event 56 million years ago known as the Palaeocene - Eocene Thermal Maximum (PETM) was driven by massive CO2 emissions from volcanoes during the formation of the North Atlantic Ocean.

These engines reportedly have a warmup strategy that makes emissions controls heat up faster, which is in itself not a violation, but may prove so if the system only activates during emissions test cycles instead of real - world driving.

I used it because I drove the car for very short distances (3 km) for long time during winter, that is when the car failed the emission test.

The start - stop system is a highly effective engine management program that can help lower fuel consumption * as well as CO2 emissions by shutting off the engine while waiting at a traffic signal or during certain stop - and - go driving.

Featuring an immediate restart with virtually no engine sound or vibration, the system delivers significant reductions in CO2 emissions during urban driving, and can lower average fuel consumption by up to 3 %, depending on driving conditions.

But, this potent internal combustion engine also benefits from a regenerative - powered electric motor driving the rear wheels either automatically when required during cornering and in strong acceleration — giving a power boost of as much as 45 ps — or in a button - activated creep - mode at low speeds to avoid emissions in city traffic or when «stealth» is required.

Now standard across the full F - 150 lineup, Auto Start - Stop Technology can help reduce fuel consumption and vehicle emissions during city driving.

In RDE tests, exhaust gas emissions — NOx (nitrogen oxide), particles (fine dust) and other — are measured during an actual drive on the road using a Portable Emissions Measurement Systeemissions — NOx (nitrogen oxide), particles (fine dust) and other — are measured during an actual drive on the road using a Portable Emissions Measurement SysteEmissions Measurement System (PEMS).

Extrapolating from their forest study, the researchers estimate that over this century the warming induced from global soil loss, at the rate they monitored, will be «equivalent to the past two decades of carbon emissions from fossil fuel burning and is comparable in magnitude to the cumulative carbon losses to the atmosphere due to human - driven land use change during the past two centuries.»

3 claims that the GHG human emission rate is approximately 2 times larger than the observed rate during the last decades, so if the Sun drives a little bit the CO2 and CH4 cycle mechanisms (which in this case are absorbing large amount of CO2 and CH4 from the atmosphere) it might leave a signal in the CO2 and CH4 record as well.

They promote spending $ 22 billion just in federal money during FY - 2014 on climate change studies; costly solar projects of every description; wind turbines that blight scenic vistas and slaughter millions of birds and bats annually, while wind energy developers are exempted from endangered species and other environmental laws that apply to all other industries; and ethanol programs that require millions of acres of farmland and vast quantities of water, fertilizer, pesticides and fossil fuel energy to produce a gasoline additive that reduces mileage, harms engines, drives up food prices... and increases CO2 emissions.

Reducing CO2 Emissions • Drive a fuel - efficient car, walk, bike, carpool, and use mass transit • Use energy - efficient windows • Use energy - efficient appliances and lights • Heavily insulate your house and seal all drafts • Reduce garbage by recycling and reuse • Insulate your hot water heater • Use compact fluorescent bulbs • Plant trees to shade your house during summer • Set water heater no higher than 49 °C (120 °F) Figure 20.16 Individuals matter: ways to reduce your annual emissionEmissions • Drive a fuel - efficient car, walk, bike, carpool, and use mass transit • Use energy - efficient windows • Use energy - efficient appliances and lights • Heavily insulate your house and seal all drafts • Reduce garbage by recycling and reuse • Insulate your hot water heater • Use compact fluorescent bulbs • Plant trees to shade your house during summer • Set water heater no higher than 49 °C (120 °F) Figure 20.16 Individuals matter: ways to reduce your annual emissionsemissions of CO2.

Similarly, emission reductions in the UK power sector were largely driven by the retirement of old, inefficient coal plant during the 1990s, through sulphur regulations which meant plant owners were faced with the choice of either retrofitting stock or retiring it (Eyre, 2001).

Using the latest data about how electricity is generated around the country, as well as crunching the numbers on the energy and materials required to build the batteries that power electric cars, UCS analysts examined all global warming emissions created during an electric car's lifetime — from its production and years of driving to its eventual retirement.

Hence, atmospheric GEM concentrations inferred from Greenland firn air and global anthropogenic Hg emissions have exhibited consistently similar trends during the most recent decades (Fig. 2), suggesting that the atmospheric reservoir of mercury at mid - and high - northern latitudes has been driven mainly by anthropogenic emissions during the last decades.

Finally, the Escape will be easier on L.A.'s notoriously bad smog: according to one Ford sales manager,» [the Escape Hybrid] releases fewer smog - forming emissions into the atmosphere during a three - hour drive (about 180 miles) than grilling one hamburger in your back yard.»

According to Car and Driver magazine, the software, which was able to activate emissions - control devices when a testing environment was detected and deactivate them during normal driving, somehow ended up in production vehicles.

These vehicles produce near zero emissions, ensuring that the thousands of miles driven during the behind the wheel instruction process are driven cleanly and efficiently.
