One of the more lasting contributions we can make in our community is to protect the environment by reducing ozone-forming emissions wherever possible. These trucks run cleaner and quieter, and will help to make the local environment healthier for future generations.
The engine is 90% cleaner than the current Environmental Protection Agency’s most stringent 0.2 Last year, we introduced a propane autogas engine that was 75% cleaner than the EPA’s emissions standard. grams per brake horsepower-hour (g/bhp-hr). Earlier post.). g/bhp-hr heavy-duty engine standard.
Use of electric vehicles would achieve greater reductions in GHG emissions, corresponding to the rate that the electric grid becomes cleaner, through greater reliance on renewables and low- and non-emitting generation. This research points to the importance of two fundamental and parallel trends in energy and the environment.
The European Community’s air pollutant emission inventory report released by the European Environment Agency finds that in 2007, sulphur oxides (SO x ) emissions were down by 72 % from 1990 levels. Energy use by households (the burning of wood, gas, coal etc) is the most important source of PM 2.5
A new report from the European Environment Agency (EEA) warns that the health of Europe’s most vulnerable citizens remains disproportionately affected by environmental hazards such as air and noise pollution and extreme temperatures, especially in Europe’s eastern and southern regions, despite overall improvements in Europe’s environmental quality.
Emissions from automobile exhaust systems have decreased in recent years due to the introduction of cleaner fuels and new control technologies on internal combustion engines, as well as increases in numbers of hybrid and electric vehicles.
in 2018 (2000-2018 average year-over-year increase is 6.8%), continuing the increasing trend as they replace Ozone Depleting Substances (ODS) being phased out under the 1987 Montreal Protocol. Because of the enormous potential impact of these products, reducing their emissions has a disproportionate benefit to the environment.
A longer service life reduces the fleet’s turnover rate to cleaner, lower-emitting engines, therefore increasing future-year emission estimates. The incentive funds give boat operators a brand new, more efficient, fuel-saving and lower-emitting engine at a fraction the cost.
Bolden said air travel is one of the safest modes of transportation and vital to the US economy, but increasing air traffic is taking a toll on the environment and the nation’s aviation infrastructure. said at the Green Aviation Summit under way through Thursday at NASA’s Ames Research Center.
FTA’s Low-No Program supports transit agencies in purchasing or leasing low- or no-emission buses and other transit vehicles that use technologies such as battery electric and fuel-cell power to provide cleaner, more efficient transit service in communities across the country.
In particular, TPS technology offers a groundbreaking approach to reducing emissions from combustion engines and improving the environment. We feel confident that our technology is ready to usher in the benefits of lower emissions, and lead the industry’s push toward cleaner mobility. hp diesel engine.
Mikhail Chester and Arpad Horvath inventoried on-road, rail, and air travel to determine energy consumption, greenhouse gas (GHG) emissions, and criteria air pollutant (CAP) emissions (excluding PM, lead, and ozone due to lack of data). 83% of rail passenger kilometers are performed by metropolitan systems (with Amtrak serving the remaining).
As the trend toward cleaner technologies with reduced exhaust emissions continues through the use of catalytic converters, diesel particulate filters (DPF), and improved fuels and engines, non-exhaust PM will soon surpass exhaust emissions and may well become dominant by 2020 both in terms of emissions and contributions to air quality.
And so back in, I believe it was the 80s, it might have been earlier than that, Paul Knutson who famously identified the ozone whole problem, he put forward the idea that putting material in the stratosphere might be an interesting way to reflect sunlight to cool the planet. And that was based on observations of volcanoes.
Neutral richii @ Apr 19th 2009 5:28PM @ everyone, I can see what your trying to say, that without gas powered vehicles that a much larger strain will be put on electrical facilities that also contribute to air pollution and degrade our environment. but its never even been close to the amount of garbage that gas power vehicles produce.
The US Environmental Protection Agency (EPA) is proposing to retain, without changes, the existing, more stringent 2015 National Ambient Air Quality Standards (NAAQS) for ozone. From 2017 to 2019, ozone concentrations fell 4%. During that same time, national average ozone concentrations have dropped 25%. Background.
