Greenhouse Gas Emission Reduction Benefits of Natural Gas for Transportation Confirmed by New NGVA Europe Study

Vancouver, British Columbia (ots/PRNewswire) -

~Westport Fuel Systems Next-Generation Natural Gas Engine and
Vehicle Technologies Validated as a Key Solution for De-carbonizing
the Transport Sector~

Westport Fuel Systems Inc. ("Westport Fuel Systems") (TSX: WPRT /
Nasdaq: WPRT) today announced the publication of a new study by
Natural Gas Vehicles Association Europe ("NGVA Europe") that
quantified the greenhouse gas ("GHG") emission reduction benefits of
natural gas for light duty and heavy duty transportation. Alongside
data from the major European vehicle and engine makers, Westport Fuel
Systems made GHG emissions data specific to the Volvo V60 Bi-Fuel
passenger car that uses its advanced natural gas technology from
Westport, and Westport High Pressure Direct Injection 2.0
("Westport(TM) HPDI 2.0") for heavy duty trucks available for the
study, enabling state of the art vehicle technologies to be included
in the assessment.

The detailed well-to-wheels lifecycle analysis concluded that
natural gas fueled passenger cars offer a 23% GHG emission reduction
benefit compared with petrol, and 7% compared with diesel assuming an
European Union ("EU") average upstream gas mix for compressed natural
gas ("CNG"). In heavy-duty applications, trucks fueled by CNG or
liquefied natural gas ("LNG") offer GHG emission reduction benefits
of 15-16% using EU average gas mix. When the highest upstream carbon
intensity originating source of LNG (from Algeria) is removed and
Westport(TM) HPDI 2.0 technology is used, reductions of 18% to 22%
were identified. These GHG benefits are significantly amplified when
blends of renewable natural gas ("RNG") or biomethane are used with
well-to-wheel emissions being reduced by 80-95% depending on the fuel
source and production pathway.

The study analysis was performed by Thinkstep, a leading global
consultant specializing in lifecycle analysis, who collected and
scrutinized the most up to date data from more than 50 industry
participants across the natural gas value chain to determine the
potential of natural gas engines and vehicles to deliver GHG emission
reductions and contribute to the de-carbonization of the transport
sector.

"Lifecycle emissions from the transport sector and the
sustainability impacts of fuel are complex calculations that depend
on different inputs and variables," said Karen Hamberg,
Vice-President of Natural Gas Industry and Government Relations.
"This study represents a significant effort to quantify lifecycle
emissions in an evolving industry already deploying new technology to
dramatically reduce or eliminate the largest sources of GHG emissions
from both upstream and vehicle sources. As major metropolitan areas
are facing increasing air quality concerns, natural gas vehicles in
all segments represent an immediate opportunity to improve air
quality and reduce GHG emissions."

"Next generation natural gas technology such as Westport(TM) HPDI
2.0, which is being launched in Europe later this year, is optimal
for heavy-duty vehicles. Westport(TM) HPDI 2.0 is the only natural
gas engine technology that provides a "no-compromise" performance
value proposition while achieving diesel engine efficiency within 1%
with inherently low engine-out unburnt methane emissions."
