How much carbon dioxide do busses produce?
How much carbon dioxide do busses produce?
the average passengers per bus is 9.2 (from 5.2 billion vehicle km and 48 billion passenger km) the average CO2 emission for the buses is 822 g / km.
How much CO2 is released by transportation?
1.9 billion tons
How much CO2 does a bus emit per kilometer?
The report states that a cyclist expels 5g/km of CO2 per passenger, and this compares with 11g/km CO2 per passenger on the Dart and 15g/km on an Intercity bus.
Which trees absorb the most pollution?
Silver birch, yew and elder trees were the most effective at capturing particles, and it was the hairs of their leaves that contributed to reduction rates of 79%, 71% and 70% respectively.
What trees clean the air the best?
Birch, the best-performing tree, removed 79 percent of these ultrafine particles from the air, while yew and elder each captured around 70 percent. Such trees could be planted at pollution hotspots to quickly improve air quality, the scientists suggest.
What is the biggest carbon sink on the planet?
The ocean, atmosphere, soil and forests are the world’s largest carbon sinks. Protecting these vital ecosystems is essential for tackling climate change and keeping our climate stable. But they’re increasingly under threat. The world’s forests absorb 2.6bn tonnes of carbon dioxide every year.
Which of the following is the largest sink for carbon dioxide gas?
ocean
What are the 5 carbon sinks on the planet?
The carbon cycle is the biogeochemical cycle by which carbon is exchanged among five spheres of the Earth, carbon (C) sinks: the biosphere, pedosphere, lithosphere, hydrosphere, and atmosphere (These are not mutually exclusive, see Glossary).
What plants soak up the most CO2?
- Pine (Ponderosa, red, white and Hispaniolan pines)
- Oake (Scarlet, Red and Virginia Live Oak)
- Douglas fir.
- Bald Cypress.
- Common Horse-chestnut.
- Black Walnut.
- London Plane.
Will higher temperatures increase or decrease CO2 solubility?
The solubility of gases decreases with increasing temperature, so the air space inside the cylinder when cold water was used will be less compared to warm water. When the water reaches the surface, it is warmed decreasing gas solubility leading to the degassing of CO2.
What is the relationship between CO2 and temperature?
When the carbon dioxide concentration goes up, temperature goes up. When the carbon dioxide concentration goes down, temperature goes down.
What increases the solubility of CO2?
When carbon dioxide reacts with water it forms carbonic acid. Increasing the pressure of carbon dioxide makes the reaction feasible in the forward direction and hence solubility of CO2 increases.
Why is there a lag between CO2 and temperature?
The time lag between CO2 and temperature is caused by a temporal offset between the oceans heating up and the constant release of oceanic CO2. Through this accumulating effect, CO2 became the primary driver of temperature during the glacial-interglacial warming.
Does temperature increase before CO2?
Although the increase in temperature occurs prior to an increase in carbon dioxide, carbon dioxide plays an important role in the retreat of an ice age. As carbon dioxide in the atmosphere increases, the greenhouse effect is strengthened, and a greater degree of warming occurs.
How hot can CO2 get?
CO2 cylinder, 68% full by water capacity, warms up to room temperature (70 oF), the pressure inside the cylinder increases to 837 psi. When the same cylinder reaches 87.9 oF the entire charge becomes a gas no matter what the pressure.
Does CO2 rise or drop?
So normally CO2 doesn’t rise in air. But when CO2 is produced by combustion, its temperature is higher than that of air. So CO2 become lighter than air at that time. Because with increasing temperature, the density of any gas decrease.
