Give me 30 seconds,

And I can give you a list of 
30 terrifying challenges

facing humanity and the planet 
at this point in history.

And we wouldn't sleep tonight.

There are so many of them, 
and they seem to be so frightening

It's not really surprising

that many of us are feeling 
a little bit disheartened,

and a little bit anxious at the moment.

But the way I see it -

There are really only two things

stopping the world working at the moment

The first one is the fact that 
the countries don't collaborate enough.

We know the solutions 
to most of those challenges.

But we don't implement them
because we don't work together.

And the second thing 
that stopping the world working properly

is the fact that every single 
one of those challenges

has been caused by the behaviour
of human beings.

And if we can change that
we can change everything.

Now those sound like 
big tasks and they are.

But I'm optimistic.

For the last 10 years, I've been working
on projects and plans and policies.

to try and attack those two barriers
to making the world work better.

Some of them I tried to encourage
countries to implement.

But the coolest ones, I keep
and I try to do them myself.

So I'd like to tell you two of those
in the few minutes that I've got today.

The first one is more of an update.

It's a project called the Good Country Index,
which I launched back in 2014.

I haven't spoken about it for a while,
but it has been through 4 different editions.

And I thought it would be good
to give an update.

So the Good Country Index is an attempt
to measure what every country on earth

gives to the rest of the world

outside of its own borders,

a kind of balance sheet
for the world if you like.

A lot of people, when I 
originally launched it said

not another country index, surely 
there are enough of those around already.

But the interesting thing is that
almost all of the others look inwards.

They treat countries as if they were little islands

inhabiting their own private oceans.

But surely that doesn't really make sense.

Because everything everybody does
has an impact on all of us, always.

If one country pollutes the air or water,
that's our air and our water.

If they go to war, 
drags other countries in

and the refugees pour out.

There is really nothing you can do any more

So what the good country 
index attempts to do

is to make a start towards 
helping people to understand

that this is an interconnected system.
