An economic case for protecting the planet Naoko Ishii

Good evening, everyone.

I am from Japan,

so I’d like to start with a story
about Japanese fishing villages.

In the past, every fisherman was tempted
to catch as many as fish as possible,

but if everybody did that,

the fish, common shared resource
in the community, would disappear.

The result would be hardship
and poverty for everyone.

This happened in some cases,

but it did not happen in other cases.

In these communities,

the fishermen developed
a kind of social contract

that told each one of them
to hold back a bit to prevent overfishing.

The fisherman would keep
an eye on each other.

There would be a penalty
if you were caught cheating.

But once the benefit of a social contract
became clear to everyone,

the incentive to cheat
dramatically dropped.

We find the same story around the world.

This is how villagers in medieval Europe

managed pasture and forests.

This is how communities in Asia
managed water,

and this is how indigenous peoples
in the Amazon managed wildlife.

These communities realized
they relied on a finite, shared resource.

They developed rules and practices
on how to manage those resources,

and they changed their behavior

so that they could continue
to rely on those shared resources tomorrow

by not overfishing,

not overgrazing,

not polluting or depleting
water streams today.

This is a story of the commons,

and also how to avoid
the so-called tragedy of the commons.

But this is also a story of an economy

that was mainly local,

where everybody had
a very strong sense of belonging.

Our economies are no longer local.

When we moved away from being local,

we started to lose
our connection to the commons.

We carried economic objectives,
goals and systems beyond the local,

but we did not carry the notion
of taking care of the commons.

So our oceans, forests,

once very close to us
as our local commons,

moved very far away from us.

So today, we pump millions of tons
of greenhouse gases into the air,

we dump plastics, fertilizers
and industrial waste

into the rivers and oceans,

and we cut down forests that absorb CO2.

We make the wild biodiversity
much more fragile.

We seem to have totally forgotten

that there is such a thing
as global commons:

air, water, forests and biodiversity.

Now, it is modern science

that reminds us how vital
the global commons are.

In 2009, a group of scientists proposed

how to assess the health
of the global commons.

They defined nine planetary boundaries
vital to our survival,

then they measured how far we could go

before we cross over
the tipping points or thresholds

that would lead us to the irreversible
or even catastrophic change.

This is where we were in the 1950s.

We broadly remained
within safe operating space,

marked by the green line.

But look at where we are now.

We have crossed four of those boundaries,

and we will be crossing others
in the future.

How did we end up in this situation?

Well, my personal story
may tell us something.

Five years ago, I was appointed

as CEO of the GEF,
Global Environment Facility,

but I am not a conservationist

or an environmental activist.

I am an economist,

and for the last 30 years,

I had worked for public finance
in my home country and around the world.

I can tell you one thing for sure:

during these 30 years,

the notion of the global commons
never crossed my mind.

I didn’t have a single conversation
about the global commons

with my colleagues.

This tells me that the notion
of the global commons

was not really entering
into the big money decisions

like state budgets or investment plans.

And I’m wondering,
why do we have this sheer ignorance

about the global commons,

including me, myself?

One possible explanation might be

that until recently,
it didn’t really matter too much.

Even if we mess up
some part of the environment,

we were not fundamentally changing
the functions of the earth system.

The global commons
had still enough capacity

to take the punches we gave them.

In fact, the fish were still plentiful,

the fields for grazing were still vast.

Our mistake was to assume

that the capacity
of the earth for self-repair

had no limits.

It does have limits.

The message from
the science is very clear:

we humans have become
an overwhelming force

to determine the future
living conditions on earth,

and what’s more,
we are running out of time.

If we don’t act on them,

we will be losing the global commons.

It’s only our generation
who are able to preserve it –

preserve the commons as we know them.

Now is the time we start managing
the global commons

as our parents or our grandparents
managed their local commons.

The first thing we need to do

is to simply recognize
that we do have the global commons

and they are very, very important.

Then we need to build
the stewardship of the global commons

into all of our thinking,

our business, our economy,

our policy-making –

in all of our actions.

We need to recreate the social contract
of the fishing villages

on the global scale.

But what does it mean in practice?

Where to start with?

I see there are four key economic systems

that fundamentally need to change.

First, we need to change our cities.

By 2050, two thirds of our population
will live in cities.

We need green cities.

Second, we need to change
our energy system.

The world economy
must sharply decarbonize,

essentially in one generation.

Third, we need to change
our production-consumption system.

We need to break away from current
take-make-waste consumption patterns.

And finally, we need
to change our food system,

what to eat and how to produce it.

And all of those four systems

are putting enormous pressure
on the global commons,

and it’s also very difficult to flip them.

They are extremely complex,

with many decision-makers,
actors involved.

Let’s take the example of the food system.

Food production is currently responsible

for one quarter
of greenhouse gas emissions.

It is also a main user
of the world’s water resources.

In fact, 70 percent of today’s water
is used to grow crops.

Vast areas of tropical forest
are used for agriculture.

This deforestation drives extinction.

In fact, we are losing species
1,000 times faster

than the natural rate.

And on top of all of that bad news,

one third of food produced today globally

is not eaten.

It’s wasted.

But there is the good news,

good signs.

Coalitions of stakeholders

are now coming together
to try to transform the food system

with one shared goal:

how to produce enough
healthy food for everyone,

at the same time,

to try to cut, to sharply reduce,

the footprint from the food system
on the global commons.

I had an opportunity

to fly over the Indonesian
island of Sumatra,

and I saw with my own eyes

the massive deforestation

to make room for palm oil plantations.

By the way, palm oil is included
in thousands of food products

we eat every day.

The global demand for palm oil
is just increasing.

In Sumatra, I met smallholder farmers

who need to make a day-to-day living
from growing oil palm.

I met global food companies,

financial institutions

and local government officials.

All of them told me that they can’t
make the change by themselves,

and only by working together
under a kind of new contract,

or a new practice,

do they have a chance
to protect tropical forests.

So it’s so encouraging to see,
at least for the last few years,

this new coalition among these committed
actors along the supply chain

come together to try
to transform the food system.

In fact, what they are trying to do

is to create a new kind of social contract
to manage the global commons.

All changes start at home,

at your place and at my place.

At GEF, Global Environment Facility,

we have now a new strategy,

and we put the global commons
at its center.

I hope we won’t be the only ones.

If everybody stays on the sidelines,
waiting for others to step in,

the global commons
will continue to deteriorate,

and everybody will be much worse off.

We need to save ourselves
from the tragedy of the commons.

So, I invite all of you
to embrace the global commons.

Please do remember
that global commons do exist

and are waiting for your stewardship.

We all share one planet in common.

We breathe the same air,

we drink the same water,

we depend on the same oceans,
forests, and biodiversity.

There is no space
left on earth for egoism.

The global commons must be kept
within their safe operating space,

and we can only do it together.

Thank you so much.

(Applause)

大家晚上好。

我来自日本,

所以我想先讲一个
关于日本渔村的故事。

过去,每个渔民都想
尽可能多地钓到鱼,

但如果每个人都这样做,

那么
作为社区共有资源的鱼就会消失。

结果将是
每个人的困难和贫困。

这在某些情况下发生,

但在其他情况下没有发生。

在这些社区中

,渔民们制定
了一种社会契约

,告诉他们每个人
都要有所保留,以防止过度捕捞。

渔夫会
互相注视。

如果你被发现作弊,将会受到处罚。

但是,一旦每个人都清楚社会契约的好处,

作弊的动机就会
急剧下降。

我们在世界各地发现了同样的故事。

这就是中世纪欧洲的村民

管理牧场和森林的方式。

这就是亚洲社区
管理水资源的方式,

也是亚马逊地区土著人民管理野生动物的方式。

这些社区意识到
他们依赖于有限的共享资源。

他们制定了
有关如何管理这些资源的规则和实践,

并改变了他们的行为,

以便他们
明天可以继续依赖这些共享资源

,不过度捕捞,

不过度放牧,

不污染或耗尽
今天的水流。

这是一个公地的故事

,也是如何
避免所谓公地悲剧的。

但这也是一个

主要是地方经济的故事

,每个人
都有很强的归属感。

我们的经济不再是地方性的。

当我们远离本地人时,

我们开始
失去与公地的联系。

我们将经济目标、
目标和制度带到了地方之外,

但我们没有
承担照顾公地的概念。

所以我们的海洋、森林,

曾经
作为我们当地的公地

离我们很近,现在离我们很远了。

所以今天,我们将数百万吨
的温室气体排放到空气中,

我们将塑料、化肥
和工业废物

倾倒到河流和海洋中

,我们砍伐了吸收二氧化碳的森林。

我们使野生生物多样性
更加脆弱。

我们似乎完全忘记

了存在
全球公域之类的东西:

空气、水、森林和生物多样性。

现在,是现代科学

提醒我们
全球公域的重要性。

2009 年,一群科学家提出了

如何评估
全球公域的健康状况。

他们定义了
对我们的生存至关重要的九个行星边界,

然后他们测量了

我们在

跨越将导致我们发生不可逆转
甚至灾难性变化的临界点或阈值之前能走多远。

这就是我们在 1950 年代所处的位置。

我们大致保持
在安全的运营空间内,

以绿线为标志。

但是看看我们现在的位置。

我们已经跨越了其中四个界限

,未来我们还将跨越
其他界限。

我们是怎么落到这种境地的?

好吧,我个人的故事
可能会告诉我们一些事情。

五年前,我被任命

为 GEF
全球环境基金的首席执行官,

但我不是保护主义者

或环境活动家。

我是一名经济学家

,在过去的 30 年里,

我一直
在本国和世界各地的公共财政部门工作。

我可以肯定地告诉你一件事:

在这 30 年里,

全球公域的概念
从未出现在我的脑海中。

我没有与同事
就全球公域

进行过一次谈话。

这告诉我,
全球公域的概念

并没有真正参与

国家预算或投资计划等大笔资金决策中。

我想知道,
为什么我们对包括我自己

在内的全球公域如此无知

一种可能的解释是

,直到最近,
它并没有太大的影响。

即使我们
破坏了环境的某些部分,

我们也没有从根本上改变
地球系统的功能。

全球公域
仍有足够的

能力承受我们给他们的打击。

其实鱼还是很

丰富的,放牧的地方还是很大的。

我们的错误是假设

地球的自我修复能力是

无限的。

它确实有限制。

来自科学的信息非常明确:

我们人类已经成为

决定地球未来
生存状况的压倒性力量

,而且
我们的时间已经不多了。

如果我们不对它们采取行动,

我们将失去全球公域。

只有我们这一代
人能够保护它——

保护我们所知道的公地。

现在是我们开始
管理全球公地的时候了,

就像我们的父母或祖父母
管理他们的地方公地一样。

我们需要做的第一件事

就是简单地认识
到我们确实拥有全球公域

,它们非常非常重要。

然后,我们需要
将全球公域的管理

纳入我们所有的思想、

我们的业务、我们的经济、

我们的政策制定——

在我们所有的行动中。

我们需要在全球范围内重建渔村的社会契约

但这在实践中意味着什么?

从哪里开始?

我看到有四个关键的经济体系

需要从根本上改变。

首先,我们需要改变我们的城市。

到 2050 年,我们三分之二的人口
将居住在城市。

我们需要绿色城市。

其次,我们需要改变
我们的能源系统。

世界经济
必须大幅脱碳,

基本上需要一代人的时间。

第三,我们需要改变
我们的生产消费体制。

我们需要摆脱
当前的浪费消费模式。

最后,我们
需要改变我们的食物系统,

吃什么以及如何生产。

而这四个体系都给全球公域

带来了巨大的
压力,

也很难翻转它们。

它们极其复杂,

涉及许多决策者和
参与者。

让我们以食物系统为例。

目前,食品生产

占温室气体排放量的四分之一。

它也是世界水资源的主要用户

事实上,当今 70% 的
水用于种植农作物。

大片热带
森林用于农业。

这种森林砍伐导致灭绝。

事实上,我们正在以比自然速度
快 1000 倍的速度失去物种

除了所有这些坏消息之外,

今天全球生产的三分之一的食物

没有被食用。

浪费了。

但是有好消息,

好兆头。

利益相关者联盟

现在正齐聚一堂
,试图改变食品系统

,实现一个共同目标:

如何为每个人生产足够的
健康食品,

同时

努力减少

、大幅减少食品系统
对 全球公域。

我有

机会飞越印度尼西亚
的苏门答腊岛,

亲眼目睹

了大规模的森林砍伐

,为棕榈油种植园腾出了空间。

顺便说一句,我们每天吃
的数千种食品中

都含有棕榈油。

全球对棕榈油的需求
正在增加。

在苏门答腊,我遇到了

需要以
种植油棕为生的小农。

我会见了全球食品公司、

金融机构

和当地政府官员。

他们都告诉我,他们自己无法
做出改变

,只有
在一种新的合同

或新的实践下共同努力,

他们才有
机会保护热带森林。

因此,
至少在过去几年中,看到供应链上

这些坚定的参与者之间的新联盟

走到一起,
试图改变食品系统,这是非常令人鼓舞的。

事实上,他们试图做的

是创建一种新的社会契约
来管理全球公域。

所有的改变都从家里开始,

在你的地方,在我的地方。

在 GEF,全球环境基金,

我们现在制定了一项新战略

,我们将全球公域置于
其中心。

我希望我们不会是唯一的。

如果每个人都袖手旁观,
等待其他人介入

,全球公域
将继续恶化

,每个人的处境都会变得更糟。

我们需要
从公地悲剧中拯救自己。

所以,我邀请你们所有人
拥抱全球公域。

请记住
,全球公域确实存在

并且正在等待您的管理。

我们都共享一个共同的星球。

我们呼吸同样的空气

,喝同样的水,

我们依赖同样的海洋、
森林和生物多样性。 地球上

已经没有任何空间
留给利己主义了。

全球公域必须保持
在其安全的操作空间内

,我们只能一起做。

太感谢了。
