International Cooperation

Collaboration with Mexico to Reduce Emissions from Ships

The Maersk Line ship "Roubaix."
Through ongoing, joint work with EPA, the Mexican government has been actively exploring international actions to reduce air pollution from ships near local communities. Mexico has been learning from the United States' experience, and is now working toward the ratification of MARPOL Annex VI (an international air pollution agreement), and establishment of a Mexican Emission Control Area (ECA). Shared work between the United States and Mexico began in 2009, and now includes Canada. 
 
As part of the International Convention for the Prevention of Pollution from Ships (MARPOL), Annex VI requires ships to reduce air pollution. MARPOL Annex VI also enables countries to designate more stringent international standards in an ECA. Countries must be party to MARPOL Annex VI to establish an ECA. In the U.S., the NA ECA became enforceable on August 1, 2012. 
 
Throughout this effort to reduce air pollution from ships, EPA and Mexico’s Ministry of Environment and Natural Resources (SEMARNAT) have been reaching out to other relevant Mexican ministries and stakeholders, initially to raise their awareness of the benefits of reducing ship emissions and, as the significant benefits to Mexico became clearer, to gain their support for this effort. 
 
In June 2016 at the North American Leaders Summit, President Obama and his counterparts from Mexico and Canada made a joint commitment to work together to support finalization and submission to the IMO of a Mexican Emission Control Area designation proposal. The action plan calls on the ongoing CEC work to implement this high level commitment.   
 
In support of this effort, EPA, SEMARNAT, Transport Canada and Environment Canada are working together under the Commission for Environmental Cooperation on two projects:
 
  • Reducing Emissions from Goods Movement via Maritime Transportation in North America

In the first phase of this project (2013-2014), Exitthe US, Mexico and Canada developed the needed analyses for Mexico’s possible ratification of MARPOL Annex VI and establishment of an ECA. The second phase (2015-2016) Exit is focusing on to facilitate the establishment and implementation of an ECA in Mexico.

  • Enhancing North American Enforcement of the IMO Maritime Fuel Sulfur Limits

The goal of this project Exitis to enhance North American capacity to assess compliance with, and enforce as appropriate, the International Maritime Organization’s fuel sulfur standards, particularly those applicable in Emission Control Areas (ECAs).

Emission Control Areas, or ECAs, set strict international standards which require that ships reduce emissions. A North American ECA was adopted and began in August 2012. ECAs are also in place for the North Sea and the Baltic Sea.

What are the requirements of the North American ECA?

Within the North American ECA, ships must switch the fuels they are using when operating within up to 200 nautical miles of the majority of U.S and Canadian Atlantic and Pacific coastal waters, French territories off the Canadian Atlantic coast, the U.S. Gulf Coast, and the main, populated islands of Hawaii.

The North American ECA also requires the reduction of nitrogen oxides from new ships after 2016.
 

Why are we implementing an ECA for North America?

The international standards will bring important benefits for human health through reducing emissions from ships.

Sulfur dioxides emissions from the combustion of high sulfur fuel are converted to sulfate particles in the air. These particles are a significant component of PM2.5, which can trigger asthma and worsen heart and lung disease, and are a significant threat to marine and terrestrial ecosystems.
 
Nitrogen dioxide emissions are a component of ground-level ozone, which forms smog.

Fuel-Switching Demonstration

Fuel Switching Demonstration

 
This report presents the results of the fuel switching demonstration, as well as port emission inventory development and emissions dispersion modeling for several ports in the Gulf of Mexico.

The U.S.-Mexico fuel switch demonstration showed the human health and environmental benefits of ships switching from high sulfur marine fuel (with fuel sulfur levels of about 35,000 ppm) to lower sulfur marine fuel (with fuel sulfur levels of 1,000 ppm).

The project engaged the maritime shipping industry and government representatives from Mexico, to raise awareness about the environmental benefits of implementing an Emission Control Area (ECA) and the North American ECA in August 2012. The demonstration program helped ports and maritime carriers gain experience in using low sulfur fuel, in accordance with the strict new international standards.
 
The results were presented at a technical workshop held in April 2010 to raise Mexican government and industry awareness of the benefits of fuel switching.
 
An outreach video on the project was produced to raise public awareness. It is currently playing at an outreach kiosk at the Veracruz Aquarium (link to Veracruz Aquarium web site), which receives millions of visitors a year.

The demonstration consisted of the following activities:

panel presentation
EPA and SEMARNAT jointly hosted a technical workshop with local and federal Mexican agencies and stakeholders to discuss the fuel switch demonstration.
  • In Fall 2009, an initial fuel switching demonstration was conducted on a small container vessel of Maersk Lines traveling between the Port of Houston, TX and the Port of Progreso, Mexico. Emissions reductions were estimated based on fuel used.
  • In April 2010, a second demonstration was undertaken with a vessel of the German-based shipping line Hamburg Süd. EPA installed monitors to measure stack air emissions before and after fuel switching, and calculated emissions reductions based on a trip from Veracruz, MX to Altamira, MX and finally to Houston. EPA also developed port emissions inventories and conducted dispersion and deposition modeling to show impacts to air quality and pollutant loadings to the Gulf of Mexico.
  • In addition to the Mexico and U.S. fuel switches, the Hamburg Süd vessel also switched fuels in Houston in July 2010 and then also conducted a fuel switch when it called on Santos, Brazil in August. View the press release from Hamburg Süd. Exit
  • EPA produced a Final Report (above) presenting the results of the fuel switching demonstration, as well as port emission inventory development and emissions dispersion modeling for several ports in the Gulf of Mexico. The fuel switching project yielded valuable emissions data to show U.S. and Mexican policy makers in the Gulf specific reductions achieved from burning lower-sulfur fuels near land in U.S. and Mexican waters. 
 

Collaboration with Mexican Stakeholders

An important early effort of the EPA-SEMARNAT collaboration on ship emissions was to raise the awareness of the Mexican public and key Mexican government agencies about the benefits of reducing these emissions through MARPOL Annex VI. Most recently the US, Mexico and Canada are working together through the Commission for Environmental Cooperation (CEC) to develop a Mexican ECA designation proposal to the IMO. The following activities have been undertaken:

May 2016: The CEC held a kick-off meeting for the Phase II Project on Reducing Emissions from Goods Movement via Maritime Transportation and the Project on Enhancing North American Enforcement of the IMO Maritime Fuel Sulfur Limits in North America in Mexico City.  The meeting was attended by Mexican government ministries (including SEMARNAT, PEMEX, the Secretariat of Communications and Transportation, the Navy, the Ministry of Economy), the US EPA, and Environment Canada.

June 2015:  The CEC completed Phase I of the Reducing Emissions from Goods Movement via Maritime Transportation in North America project. This project developed the technical tools and analyses needed to assist Mexico in establishing an ECA, including a draft ECA designation proposal to the IMO.

May 2015: EPA published the results of the first Mexican ship emissions inventory, which was used as the basis of technical analyses by the CEC. 

In September 2012, Mexican Environment Secretary Juan Elvira and EPA Administrator Lisa Jackson sign a Memorandum of Understanding for cooperation between EPA and Mexico’s Environment Agency, which includes work on ship emissions.

June 2013: At the Third Environmental Congress of PEMEX, Mexico's state-owned petroleum company, EPA presented about the North American ECA. SEMARNAT presented results of the first Mexican ship emission inventory.

September 2012: EPA and SEMARNAT signed a Memorandum of Understanding (MOU) on cooperation in coastal and aquatic environments to promote such joint work, including work on ship emissions.   EPA assisted with outreach to Mexican government and industry stakeholders through a ship emission control technology seminar.

February 2012: To demonstrate EPA’s appreciation for this partnership, EPA’s Administrator Lisa Jackson presented Minister of Environment Elvira the Gulf Guardian Award for this work.

April 2010: EPA and SEMARNAT conducted a technical workshop on the outcomes of the fuel switching demonstrations to further government and industry awareness of the benefits of fuel switching and ECAs. Explore report, news, articles and presentations from the technical workshop.

Ship Technology Seminar

On September 26, 2012, a ship technology seminar was held to provide Mexican stakeholders with information about some of the ship technologies needed to meet the requirements of MARPOL Annex VI and an ECA.

Morning session presentation by representative from Mexico’s health ministry.
The seminar was jointly sponsored by EPA, the U.S. Department of Commerce, and the Manufacturers of Emission Controls Association to increase the capacity of foreign entities to address environmental concerns while fostering export opportunities for the U.S. environmental industry. The seminar helped to raise the awareness of public and private stakeholders about the benefits of an ECA, including learning more about the technologies required to reduce pollution from shipping.
 
A broad set of over 40 stakeholders attended the seminar, including key Mexican government agencies, industry representatives and technology representatives.
 
The morning session included discussion of:
  • MARPOL Annex VI and ECAs,
  • the U.S. and Mexican government experience,
  • a shipping industry view, and
  • how this environmental policy is driving the development of ship emission control technologies.

The afternoon session focused on the available ship emissions technologies and implications for Mexican shipping and economic development. Both sessions increased the stakeholder awareness of the importance of addressing ship emissions, and the available technological options to do so.

Technical Workshop on Fuel Switching Demonstration

The Hamburg Sud demonstration vessel leaves Veracruz port on lower sulfur marine fuel.
To further Mexican government and industry awareness of the benefits of fuel switching and the ECA, EPA and the Mexican federal government conducted a technical workshop in April 2010 at the Port of Veracruz in Mexico.
 
Following on the demonstration, this workshop provided Mexican government and industry stakeholders and opportunity to learn first hand about this issue and to gather information on how to address marine emissions in the future. It was well attended by officials from local, municipal, state and federal agencies, including the State of Veracruz, SEMARNAT and PEMEX.
 
It also showcased a practice that will help the international shipping industry meet the new ECA regulations -- improving air quality and human health in coastal states.
