==The US ETV Program==

The Environmental Technology Verification (ETV) Program of the [[United States Environmental Protection Agency|Environmental Protection Agency]] (EPA) in the [[United States]] develops testing protocols and verifies the performance of innovative environmental technologies that can address problems that threaten human [[health]] or the [[natural environment]].<ref name="WHO">{{cite web |title=Ten threats to global health in 2019 |url=https://www.who.int/vietnam/news/feature-stories/detail/ten-threats-to-global-health-in-2019 |website=www.who.int |language=en}}</ref> ETV was created to accelerate the entrance of new environmental technologies into the domestic and international marketplace by providing objective technology information on commercial-ready technologies. ETV is a voluntary program. Developers/vendors of environmental technologies are not required to participate in the program, nor are they required to seek verification. ETV does not pass or fail and does not rank technologies. All verification reports and statements are made publicly available on the [https://green-business.ec.europa.eu/eu-environmental-technology-verification_en ETV Website].

===Centers===
ETV has five centers called verification organizations, which are run through a cooperative agreement: Advanced Monitoring Systems center, Air Pollution Control Technology center, Drinking Water Systems center, Greenhouse Gas Technology center, and Water Quality Protection center.{{Cn|date=December 2024}}

====Environmental and Sustainable Technology Technology Verifications (ESTE)====
A component of ETV which was added in 2005 to address priority environmental technology categories for meeting the USEPA needs for credible performance information. Priority is given to technologies that can address high-risk environmental problems.

===ETV Accomplishments, impacts, and outcomes===
ETV has verified over 400 technologies and developed more than 90 protocols. A survey of participating vendors completed in 2001 showed overwhelming support for the ETV program. Responses indicated that 73 percent of the vendors were using ETV information in product marketing, and 92 percent of those surveyed responded that they would recommend ETV to other vendors. {{Cn|date=September 2022}}

In 2006, EPA published a two-volume set of case studies which document actual and projected outcomes from verifications of technologies in 15 technology categories ([http://www.epa.gov/nrmrl/std/etv/pubs/600r06001.pdf ETV Program Case Studies Vol 1 EPA/600/R-06/001] and [http://www.epa.gov/nrmrl/std/etv/pubs/600r06082pv.pdf ETV Program Case Studies Vol II EPA/600/R-06/082]).

An Association of State Drinking Water Administrators (ASDWA) survey showed that 34 states recognize and use ETV reports. ASDWA and its members rely heavily on these evaluations to support the use of new technologies and products in the drinking water industry. {{Cn|date=September 2022}}

Designating a product or technology as ETV “verified” does not mean a given technology reduces every [[Air pollution|emission]], has no drawbacks, or outperforms solutions ''not'' on the “verified” list.

Designating a product or technology as “verified” means that a given technology produced “X” outcome, when tested according to a specific protocol.

===Verified diesel emission reduction technologies and their outcomes===
*[[Biodiesel]]: Reduced inorganic (soot) carbon emissions, Increased NOx emissions - Increased organic carbon (SOF / VOC) emissions.
*[[Diesel Particulate Filter]] (various manufacturers): Reduces TPM, Does Not Address NOx.
*[[Diesel Oxidation Catalyst]] (various manufacturers) : Reduces TPM, Does Not Address NOx.
*Clean Diesel Technologies fuel borne catalyst: potential fine metallic emissions & potential resulting health effects - need PM filter - minimal NOx reduction.
*Purinox - water / diesel fuel emulsion: PM/HC/CO emissions can increase as a result of tuning to compensate for decreased power- only summer blend verified.
*Envirofuels Diesel Fuel Catalyzer: verified on tier 0 locomotive engine - verification report specifies an increase in total particulate (TPM) emissions on the treated fuel, as compared to the baseline fuel, even though the gaseous emissions and visible smoke opacity decreased significantly.
*Envirofuels diesel fuel catalyzer showed a verified fuel consumption reduction.
=== Composition of total diesel particulate matter and the relation to smoke opacity===
The composition of TPM (total [[diesel particulate matter]]) is the sum of "dry" particulates, and "wet" particulates.

"Dry" Particulate emissions are also known as inorganic soot, black carbon, or elemental carbon.

"Wet" particulates are also known as [[organic carbon]], [[soluble organic fractions]] (SOFs) and [[volatile organic compounds]] (VOCs).

The exact ratio of "wet to dry" diesel particulate matter will vary by engine load, duty cycle, fuel composition and specification, and engine tuning.

An opacity reading is a measurement of the level of ''visible'' inorganic carbon, also known as soot. Opacity measurements cannot detect organic carbon emissions, VOC / SOF emissions, or NOx emissions.

Specialized instrumentation is required to determine organic carbon levels, and to detect other unseen particulates. When used in conjunction with an opacity meter, the technician can detect (for example) an increase in TPM, and detect a decrease in visible smoke (opacity) emissions.

=== Function as a neutral clearinghouse ===
The ETV verification program (and other verification pathways) publish the verification reports, technology options charts, and technical summaries, once testing has been completed.

The ETV testing facility will issue press releases on behalf of the technology vendor, upon completion of testing.

The ETV verification program reports all outcomes, and leaves the ultimate decision regarding the suitability and applicability of a given technology to the discretion of the end user. Additional research may be necessary in order to adequately address specific situations.

The European Commission has taken the decision to discontinue its work on the ETV programme as of November 2022, following an internal assessment.<ref>{{Cite web |title=EU Environmental Technology Verification |url=https://green-business.ec.europa.eu/eu-environmental-technology-verification_en |access-date=2023-01-23 |website=green-business.ec.europa.eu |language=en}}</ref>

===The European Union ETV Pilot program===
Environmental Technology Verification (ETV) is a new tool to help innovative environmental technologies reach the market. Claims about the performance of innovative environmental technologies can be verified by qualified third parties called "[http://iet.jrc.ec.europa.eu/etv/verification-bodies Verification Bodies] {{Webarchive|url=https://web.archive.org/web/20141201024618/http://iet.jrc.ec.europa.eu/etv/verification-bodies |date=2014-12-01 }}". The "[http://iet.jrc.ec.europa.eu/etv/verified-technologies Statement of Verification] {{Webarchive|url=https://web.archive.org/web/20150210051343/http://iet.jrc.ec.europa.eu/etv/verified-technologies |date=2015-02-10 }}" delivered at the end of the ETV process can be used as evidence that the claims made about the innovation are both credible and scientifically sound. With proof of performance credibly assured, innovations can expect an easier market access and/or a larger market share and the technological risk is reduced for technology purchasers.
