Transcripts

you know you should probably reduce it

but what exactly is

your carbon footprint

[Music]

a carbon footprint refers to the total

amount of greenhouse gases released into

the earth's atmosphere

as a result of the activities of an

individual or an organization

remember greenhouse gases trap heat

inside the atmosphere

and that's overheating the planet so if

you want to work out your own carbon

footprint

you need to know the amount of

greenhouse gases like carbon dioxide

you're responsible for creating it's a

difficult thing to measure precisely and

there are different definitions

about how best to calculate it but

roughly speaking

there's the direct impact of using

energy when we travel

or to power our homes and there's the

indirect impact of the energy that's

used to create all the things we use or

consume

in the developed world in particular

transport is a big part of your carbon

footprint

cutting down on the use of petrol or

diesel cars

and taking fewer flights is one of the

most effective ways of reducing it

the place you live also contributes to

your personal footprint

it's important to make sure your home is

heated or cooled efficiently

and is well insulated the more you can

use sustainable energy like

solar or wind power the more you cut

your emissions

the stuff you use at home also adds to

the problem

all that plastic metal and cardboard

takes a lot of energy

to produce and dispose of so recycling

can help reducing your carbon footprint

but not as much as how you travel or

heat and cool your home

then there's your diet above all red

meat makes your carbon footprint bigger

because cows produce so much methane

another greenhouse gas

and huge numbers of trees are cut down

to create pastures

on which cattle can graze in the

developing world

polluting stoves are a real problem too

so

it's important to try to replace them

with more efficient methods of cooking

but overall people in poorer countries

produce

far smaller amounts of greenhouse gases

than people in richer countries do

so if you look at just what a country

produces the average amount of carbon

dioxide emissions per person

in the united states is about 16.1

tonnes per year

in china it's 7.1 tonnes and in the uk

it's about 5.5 tonnes but in the

democratic republic of

congo it's only naught point nought

three tonnes

while in qatar which has a really small

population

but produces so much oil and gas it's

38.6 tonnes

now that's just production it doesn't

take account of all the other things

we've talked about how much you consume

but obviously the more money you have

the more you tend to consume

so if people in richer countries really

want to reduce their carbon footprint

they need to make huge changes in their

lifestyles

it can be done and new technologies to

make things greener

are coming on stream all the time but it

is a reminder that the declared aim in

many countries

of going carbon neutral by the middle of

this century

means a revolution in the way we live
