ZETs Deliver Climate & Health Benefits
Representing less than four percent of the global on-road fleet, trucks are responsible for about 27% of global on-road fuel and greenhouse gas emissions.
They are also responsible for more than 60% of on-road nitrogen oxides (NOx), which can cause decreased lung function and exacerbate dangerous respiratory ailments.[infographic for above data]
Without ZETs, climate emissions from trucks are projected to grow exponentially over the next three decades.[infographic for above projection]
ZETs can reduce pollution and improve air quality – especially in lower income communities and communities of color where dangerous air pollution causes a disproportionate risk of asthma, heart and lung disease and even early death.
DATA POINT: When compared to white people, people of color in the United States are 61% more likely to live in a county with unhealthy air. People of color are three times more likely to live in a county that fails air quality grades for particulate matter and ozone pollution.

DATA POINT: The global share of diesel in overall oil-based road fuel consumption rose from 38% in 2000 to nearly 45% in 2019, due to greater road freight activity. (COURTESY IEA)
Representing only four percent of the global on-road fleet, trucks are responsible for roughly 27 percent of global on-road greenhouse gas emissions. Many nations, even those considered climate leaders, fear big trucks are too challenging to regulate. Those fears, however, are based on outdated information. Zero-emission heavy-duty trucks are coming on the market faster than expected, battery prices are dropping quickly, price parity with diesel vehicles is on the horizon, and current ranges meet the needs of many fleets today.
