Growing Global Trend: Lower Sulfur Content in Diesel

Stratas Advisors Ranks Top 100 Countries

Sweden continues to reign at number one with advancements in policies followed by Germany, Japan and Finland. European countries dominate the top 40

HOUSTON, March 16, 2016 /PRNewswire/ -- Stratas Advisors' annual top 100 rankings report affirms a continued global movement toward lower sulfur content in diesel. For decades, policymakers and industry leaders have placed emphasis on reducing sulfur limits in fuels. Sulfur compounds (naturally found in crude oil) have adverse environmental and health effects when emitted into the air through fuel combustion. Diesel de-sulfurization dramatically improves tailpipe emissions.

Stratas Advisors' report cites a number of countries that have positioned themselves through policy initiatives to make advances in the near future. Sweden continues to reign at number one followed by Germany, Japan and Finland. European countries dominate the top 40. Since January 2009, they have been required to implement 100-percent market penetration of sulfur-free (less than 10 ppm) fuels. Sweden led the way with full market penetration in 1990. Sixteen countries moved up or were newly added to the 2016 rankings.

"Sulfur continues to be a key parameter in diesel quality improvement around the world," said Huiming Li, Director - Global Fuel Specifications. "Eight countries moved up the ranking because of reductions in diesel sulfur limits in 2015-2016. These 8 countries came from the emerging economies of Asia Pacific, Latin America and the CIS, including Russia which moved to a diesel sulfur limit of 10 ppm starting January 1, 2016."

Kyrgyzstan, Macau, Paraguay, Philippines, Russia, Sudan, Ukraine and Vietnam moved up because of changes in sulfur limits over 2015-2016.

Bahrain, Belarus, Fiji, Kazakhstan, Lesotho, Malawi, Mozambique and Papua New Guinea did not see changes in their sulfur limits during 2015-2016, but moved up as a result of Azerbaijan, Qatar, Turkmenistan and U.A.E. moving down the rankings.

Other than sulfur reduction, these elements are also important in determining diesel quality: cetane, lubricity, polyaromatics, density and cold flow.

To establish the rankings, four primary criteria were used (in order of importance):

  1. Maximum allowable limits in national standards and legislation
  2. Year of implementation for sulfur limits as required by legislation, and year of voluntary implementation — if any
  3. Limits in local or regional standards (such as specifications for cities or states)
  4. Market levels are also used wherever available to more accurately rank countries sharing the same legislated limit
