The Biggest Footprint: Eight billion humans. One clumsy giant.

Product Information

In its report on the CO 2 Emissions from Commercial Aviation, the International Council on Clean Transportation provides a nice breakdown of how the carbon intensity (grams CO 2 emitted per passenger kilometer) varies depending on flight distance. 10 To achieve these goals, the report recommends starting by establishing a robust due diligence obligation on businesses that also applies to the finance sector, and to both illegal and legal deforestation and conversion. In the chart here we see the comparison of travel modes by their carbon footprint. These are measured by the amount of greenhouse gases emitted per person to travel one kilometer. Millennium Dome".

We can calculate the contribution of the average citizen of each country by dividing its total emissions by its population. This gives us CO 2 emissions per capita. In the visualization we see the differences in per capita emissions across the world.

Ecological footprint is a metric computed by the Global Footprint Network and used to determine the impact humans are having on the environment in a given place or country. Ecological footprint measures the natural resources humans are consuming in the environment through activities such as forestry, farming, fishing, mining, and manufacturing. Especially when considered alongside complementary metrics such as biocapacity, ecological footprint can help individuals understand their impact on the planet; guide countries in improving sustainability and well-being, and inform local leaders allocating funding for public projects. Rising emissions and living standards in North America and Oceania followed soon after developments in the UK.Land Use, Land-Use Change, and Forestry in the United States is a net sink and offsets 12% of these greenhouse gas emissions. This net sink is not shown in the above diagrams. All emission estimates from the Inventory of U.S. Greenhouse Gas Emissions and Sinks: 1990–2021. Emissions and sequestration of CO 2 are presented under the Land Use, Land-Use Change, and Forestry sector in the Inventory. Emissions of methane (CH 4) and nitrous oxide (N 2O) also occur as a result of land use and management activities in the LULUCF sector. Other emissions from CH 4, and N 2O are also presented in the Energy sector. Emissions and Trends If you can’t walk or cycle, then public transport is usually your best option. Trains are particularly low-carbon ways to travel. Taking a train instead of a car for medium-length distances would cut your emissions by around 80%. 4 Using a train instead of a domestic flight would reduce your emissions by around 86%. 5

Etminan et al. (2016) estimated the radiative forcing of the change in methane concentration from 1750 to 2011 to be 0.62 watts per meter squared. The total radiative forcing over this period has been estimated at 2.75 watts per meter squared. Methane was therefore responsible for 23% [0.62 / 2.75 *100] of warming. Estimates on the footprint of cycling therefore vary. Some estimates put this figure at around 16 grams CO 2e per kilometer based on the average European diet. In his book ‘ How bad are bananas: the carbon footprint of everything’, Mike Berners-Lee estimates the footprint based on specific food types. He estimates 25 grams CO 2e when powered by bananas; 43 grams CO 2e from cereal and cow’s milk; 190 grams CO 2e from bacon; or as high as 310 grams CO 2e if powered exclusively by cheeseburgers. Modernist university building (built 1970–1976) aspiring to bring all faculties together into one huge building. The emissions shown here relate to the country where CO 2 is produced (i.e.production-based CO 2) , not to where the goods and services that generate emissions are finally consumed. We look at the difference in each country’s production vs. consumption (trade-adjusted) emissions here.

Reducing Emissions from Electric Power Production

Walk, cycle or run when possible – this comes with many other benefits such as lower local air pollution and better health;

As an example: the global mean emissions for one kilogram of beef from non-dairy beef herds is 100 kilograms of CO 2eq. Methane accounts for 49% of its emissions. So, if we remove methane, the remaining footprint is 51 kgCO 2eq (shown in red). Researchers – David Lee et al. (2020) – estimate that aviation accounts for around 2.5% of global CO 2 emissions, but 3.5% of radiative forcing/warming due to these altitude effects. Ecological footprint is often subtracted from biocapacity to determine an environment's "biocapacity reserve," which displays the supply/demand comparison as a single number. A positive biocapacity reserve means the environment is producing or replenishing resources faster than humans are currently consuming them. A negative reserve means that humans are using the resources faster than the environment can replenish them.

Geophysical Research Letters, 43(24), 12-614. Drinking water and wastewater systems account for approximately 2% of energy use in the United States. By incorporating energy efficiency practices into their water and wastewater plant, municipalities and utilities can save 15 to 30% in energy use.

Fluorinated gases (mainly hydrofluorocarbons, or HFCs) used in air conditioning and refrigeration systems can be released during servicing or from leaking equipment. Suvarnabhumi Airport fact sheet".
