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 ...
average Emissions per capita (tons per year) % change from 2000 2023 2000 World: 100%: 4.86: 4.19 +16%
This is one of the highest per capita figures in the world. [90] The footprints per capita of countries in Africa and India were well below average. Per capita emissions in India are low for its huge population. But overall the country is the third largest emitter of CO 2 and fifth largest economy by nominal GDP in the world. [91]
Every car has an optimal speed range that results in minimum fuel consumption, but this range differs between vehicle types, design and age. ... (and therefore emissions) by driving more smoothly ...
Earth is speeding to 2.5 to 2.9 degrees Celsius (4.5 to 5.2 degrees Fahrenheit) of global warming since pre-industrial times, set to blow well past the agreed-upon international climate threshold ...
However, the main disadvantage of measuring total national emissions is that it does not take population size into account. China has the largest CO 2 and GHG emissions in the world, but also the second largest population. Some argue that for a fair comparison, emissions should be analyzed in terms of the amount of CO 2 and GHG per capita. [7]
The following table lists the 1970, 1990, 2000, 2010, 2020, 2021, 2022, and 2023 annual GHG [n 1] emissions estimates (in kilotons of CO 2 equivalent per year) along with a list of calculated emissions per capita (in metric tons of CO 2 equivalent per year).
Emissions generated by all the travel, gifts, energy, decorations, food, drink and waste associated with Christmas Day amount to 513kg of CO2 equivalent (CO2e) per person - compared to 22kg a day ...
