Emissions from tractors and construction equipment

Background

Mobile machinery (such as tractors) used in agriculture and forests emit about 1 200 000 ton of CO₂ each year; together with other large non road mobile machinery (NRMM) they emit about 2 800 000 ton CO₂ [1] . Agricultural machinery also emits 2 600  ton of CO (5 900 ton if all NRMM are included), 1 000 (2 200) ton of HC, 9 700 (23 700) ton of NO_X and 470 (1 020) ton of particulate matter.

In total Sweden emits about 64 000 000 ton CO₂-equivialents (that also includes other greenhouse gases, however, greenhouse gas emissions from NRMM are almost exclusively CO₂), 154 000 ton NO_X och 174 000 ton flyktiga organiska ämnen (vari HC ingår). Emissions from NRMM constitute such a large fraction of the total emissions that it is imperative to investigate what can be done to reduce the emissions (further reading)
