MESA offers services that aim to reduce mobile source emissions through intelligent test plan design, partnerships with cutting edge test equipment providers, field & lab-based testing programs, project management, and applied technology – while aggressively pursuing client opportunities for diversification, penetration, and expansion in clean air markets.  MESA provides its customers with the ability to compare their current risk /asset management strategies with state-of-the art methodologies. 

MESA Emissions Testing + Analytical Services include:

Testing:MESA provides engine and chassis tests through a network of U.S. laboratory-based facilities as well as on-board, Portable Emissions Measurement System (PEMS) to evaluate environmental performance through measured emissions. These tests can help evaluate the environmental performance of alternative and biodiesel fuels, renewable energy and emission-reducing technologies and provide independent third-party verification of vehicle and greenhouse gas emissions.

  • Field testing (PEMS, iPEMS, etc.) as well as in-house engine dyno and chassis dyno capabilities;
  • Analysis in laboratory test facilities and with portable emissions measurement systems to determine the effectiveness of energy efficiency and emissions remediation strategies;
  • State-of-the-art technical services that effectively meet the requirements of complex energy and emissions regulations.

Sustainable Transportation: Transportation fleet managers now have an important means of managing the complex and critical risks associated with complex fleet asset management by harnessing the power of the MESA data exchange system.  This powerful information platform leverages the analytical comparison of Big Data along with resident customer vehicle performance data.  The process of employing a “three-dimensional” comparison & analysis of transportation performance data in real time results in the ability of fleet managers to more effectively design, maintain and manage one of corporate America’s largest financial assets.

The bottom line: creating multi-phase plans for transportation and logistics oriented businesses that reduce an organization's carbon footprint and emissions such as greenhouse gases while using technologies that increase efficiency while creating fuel savings encompasses MESA's Sustainable Transportation Services.

MESA helps clients obtain U.S. Environmental Protection Agency (USEPA) SmartWay certification through the implementation of the program's Action Plan, including model calculations and guide development. 

Strategic Advisory: MESA constantly monitors clean air markets, to identify and predict opportunities for market penetration, development and expansion. By assessing the impact of emissions-related legal regulations, MESA can relay the relevant impacts to paying clientele.

Advanced Vehicle Technology: Harnessing available and original technology, MESA provides emissions solutions and technology demonstrations for on-road, non-road, marine and locomotive vehicles and equipment including exhaust after-treatment retrofits and idle reduction in addition to biodiesel and alternative fuels.

Environmental Compliance: MESA helps clients meet environmental regulatory compliance standards as set by organizations like the California Air Resource Board (CARB), the EPA and the Mine Safety and Health Administration (MSHA).

Incentive Program Guidance: Guiding clients through the constantly-changing rules of State and Federal incentive guidance grant programs (such as the Texas Emissions Reductions Program) represents a significant portion of the company's services. MESA helps clients receive grant funding for vehicle and equipment upgrades, retrofits, and replacements, as well as renewable and clean energy projects.

Project Management: With special concentration on vehicular retrofits, MESA puts into effect extensive projects utilizing relationships with dealers and lawmakers with the company's own technical know-how.
