Quantitative NO x
and VOC
Emission Reductions
In the Ozone Annex, the United States provided NO x
and VOC emission reduction estimates associated
with the application of the control strategies identifi ed
under Part III B and Part IV of the Annex. The EPA
has updated these estimates using national data sets
that were completed in late 2007.
The specifi c emission reduction obligations
(see Figure 17) are now estimated to reduce annual
NO x
emissions in the PEMA by 53% (versus the
predicted overall emission reduction rate of 43%)
and annual VOC emissions in the PEMA by 41%
(versus the predicted overall emission reduction rate
of 36%) by 2010, from 1990 levels. Note that the U.S.
emissions projections are based on implementation
of the Clean Air Interstate Rule. A CAIR replacement
rule has not been fi nalized, thus revised emissions
projections that refl ect this new regulation are not
currently available. Since CAIR remains temporarily
in effect until it is replaced, the U.S. anticipates that
the 2010 projected emissions reductions will be
comparable to those shown in Figure 17.

VOC
Reporting PEMA Emissions
Provide information on all
anthropogenic NOx and all
anthropogenic and biogenic
VOC emissions within the PEMA
from a year that is not more than
two years prior to the year of the biennial progress
report, including:
JOINT COMMITMENT
• annual ozone season (May 1 to September 30)
estimates for VOC and NO x
emissions by the
sectors outlined in Part V, Section A, of the
Ozone Annex; and
• NO x
and VOC five-year emission trends for the
sectors listed above, as well as total emissions.
Canada and the United States have complied with
emission reporting requirements in the Ozone Annex.
Canada’s National Pollutant Release Inventory
(NPRI) provides a comprehensive emissions
inventory for pollutants such as NO x
, VOCs, SO 2
,
total PM, PM 10
, PM 2.5
, and CO that contribute to
acid rain, ground-level ozone and components of
smog. This comprehensive inventory is based on
two components:
• mandatory annual reporting of emissions by more
than 8,700 facilities; and
• emission estimates compiled for various sources
such as motor vehicles, residential heating, forest
fi res and agricultural activities.
The information reported by facilities is publicly
available on the Environment Canada website
at .
