A European study of nearly 2000 participants showed that an average person cycling 1 trip/day more and driving 1 trip/day less for 200 days a year would decrease mobility-related lifecycle CO 2 emissions by about 0.5 tonnes over a year, representing a substantial share of average per capita CO 2 emissions from transport (which are about 1.5 to ...
Emissions from all non-road engines are regulated by categories. [48] In the United States, the emission standards for non-road diesel engines are published in the US Code of Federal Regulations, Title 40, Part 89 (40 CFR Part 89). Tier 1–3 Standards were adopted in 1994 and was phased in between 1996 and 2000 for engines over 37 kW (50 hp ...
In more recent studies, the average fuel economy for new passenger car in the United States improved from 17 mpg (13.8 L/100 km) in 1978 to more than 22 mpg (10.7 L/100 km) in 1982. [6] The average [a] fuel economy for new 2020 model year cars, light trucks and SUVs in the United States was 25.4 miles per US gallon (9.3 L/100 km).
By 2027, CO2 emissions must drop about 50% to 170 grams of CO2 per mile on average. CO2 emissions from vehicles have led to the concentration of greenhouse gases in the atmosphere, trapping heat ...
In 2012, Drayson Racing introduced the Lola B12 69/E: a modified a Lola prototype chassis, [9] [10] [11] and set a world record for electric cars in 2013. [12] In 2019, ACO has announced Mission H24 to bring hydrogen-powered racing car to 24 Hours of Le Mans in 2024. [13] The Volkswagen I.D. R has set various records from 2018 to 2020.
HBEFA computes the selected emission factors either as weighted emission factors per vehicle category, per emission stage (e.g. EURO-5-passenger cars, etc.), per fuel type (gasoline, diesel, alternatives) or per sub-segment (= vehicle category/size class/emission stage, such as passenger cars with engine size <1.4 l EURO-3, etc.) and per traffic situation.
The world record in Diesel efficiency was achieved by a team from the Universitat Politècnica de Valencia (Politechnical University of Valencia, Spain) in 2010 with 1396.8 kilometres per litre. In contrast, the most efficient production Diesel passenger cars achieve 60 mpg ‑US (4 L/100 km; 72 mpg ‑imp ), and some high-powered sports cars ...
Maximum limits are 2.7 grams per kilometre (4.35 g/mi) of CO, 0.39 grams per kilometre (0.63 g/mi) of HC, and 0.48 grams per kilometre (0.77 g/mi) of NO x. One interesting detail of the Japanese emissions standards was that they were introduced in a soft manner; that is, 1978 model year cars could be sold that did not meet the 1978 standards ...
