In 2015, we saw two fantastic, hopeful breakthroughs for humanity.
0
12580
5313
00:17
First, the adoption of the Sustainable Development Goals,
1
17917
3198
00:21
the collective, universal plan for humanity
2
21139
2994
00:24
to eradicate hunger,
3
24157
1304
00:25
[promote] good economic development and good health,
4
25485
2476
00:27
within global environmental targets.
5
27985
1738
00:29
Secondly, after 21 years of negotiations,
6
29747
2869
00:32
we adopted the legally binding Paris Agreement,
7
32640
3050
00:35
all nations in the world keeping global warming under two degrees Celsius,
8
35714
3553
00:39
aiming at 1.5 degrees Celsius.
9
39291
2261
00:41
Today, three years down the line, we're still in the hand-waving business.
10
41576
5537
00:47
Now, I think it's time to step back one step
11
47745
2625
00:50
and recognize that I wonder if the world leaders really knew what they signed
12
50394
4486
00:54
at the General Assembly three years ago.
13
54904
2114
00:57
These are universal, aspirational, transformational goals
14
57519
3383
01:00
for inclusive, prosperous humanity on a stable earth system.
15
60926
4959
01:05
But there are underlying problems.
16
65909
2031
01:07
We have inherent contradictions between these goals,
17
67964
3205
01:11
where there's the risk of pursuing one favored goal at the expense of others.
18
71193
4868
01:16
Take, for example, Goal 8, on decent work and economic growth.
19
76084
3336
01:19
If we continue doing that by exploiting natural resources
20
79444
2696
01:22
and burning fossil fuels,
21
82164
1216
01:23
it will be impossible to reach Goal 13.
22
83404
3038
01:26
Three years down the line, we simply must admit
23
86466
2516
01:29
we're seeing limited action to really, really address this
24
89006
4157
01:33
as an inclusive, collective, universal package.
25
93187
3372
01:37
Now, this requires us to step back one step.
26
97143
3319
01:40
I think we have to ask ourselves some hard questions:
27
100486
2686
01:43
Do we have any chance of accomplishing the Sustainable Development Goals by 2030?
28
103196
4978
01:49
Are there actually inherent trade-offs
29
109000
1927
01:50
that are not compatible with our current development paradigm?
30
110951
4394
01:55
But are there, perhaps, synergies where we can really accelerate change?
31
115369
3443
01:58
And is it really a people-planet agenda,
32
118836
2172
02:01
really taking seriously the social and economic aspirational goals
33
121032
5568
02:06
within the life-support systems on earth?
34
126624
3339
02:10
Now, citizens across the world have started to recognize
35
130755
2757
02:13
that we're facing global rising environmental risks;
36
133536
3047
02:16
in fact, that a stable planet is a prerequisite
37
136607
2957
02:19
to have good human well-being on earth.
38
139588
3030
02:22
We need to define a safe operating space on a stable earth system,
39
142642
4477
02:27
and the planetary boundary framework was introduced
40
147143
2854
02:30
by the scientific community in 2009
41
150021
2101
02:32
to do exactly that.
42
152146
1818
02:34
It has now been widely embraced across the world
43
154393
2866
02:37
in policy, business and communities
44
157283
2351
02:39
as a framework for sustainable development
45
159658
2330
02:42
in the Anthropocene.
46
162012
1351
02:43
This slide really shows the framework with the nine environmental processes
47
163387
6048
02:49
that regulate the stability of the earth system,
48
169459
2316
02:51
providing a safe operating space,
49
171799
1802
02:53
where we'll have a high chance of having good human well-being
50
173625
3407
02:57
and prosperity and equity.
51
177056
1507
02:58
If we move into the yellow zone, we enter a dangerous uncertainty zone;
52
178587
4351
03:02
and into the red, we have a high likelihood of crossing tipping points
53
182962
3457
03:06
that could take us irreversibly away from the ability of the earth system
54
186443
4048
03:10
to provide social and economic well-being for humanity.
55
190515
3940
03:15
Now, we can today, scientifically, quantify these boundaries,
56
195295
4818
03:20
providing us a stable earth system for humanity.
57
200137
3578
03:24
But we have to go beyond this
58
204192
1733
03:25
and recognize the Sustainable Development Goals --
59
205949
2338
03:28
if we really want to seriously accomplish them --
60
208311
2337
03:30
must now occur within this safe operating space.
61
210658
3240
03:33
We need to achieve SDGs within PBs.
62
213922
3520
03:38
But dear friends, not even this is enough.
63
218159
2962
03:41
We need to recognize that the Sustainable Development Goals
64
221145
2810
03:43
is 12 years away.
65
223979
1492
03:45
It's only a milestone.
66
225495
1688
03:47
It is the bull's-eye that we need to go through
67
227207
2954
03:50
and zoom ourselves towards transformations
68
230185
2899
03:53
where we can have a good future for all co-citizens on earth,
69
233108
3726
03:56
nine billion plus,
70
236858
1265
03:58
within a stable earth system in 2050 and beyond.
71
238147
3602
04:02
This is a quest,
72
242405
1784
04:04
and in order to really explore this and not have only opinions about it,
73
244213
3538
04:07
we gathered the scientific community, the best thinkers and modelers
74
247775
3312
04:11
and started to develop a completely new complex systems dynamic model,
75
251111
3822
04:14
the Earth-3 model,
76
254957
1166
04:16
building on models that have been around for the last 50 years.
77
256147
4227
04:20
And here it is.
78
260815
2150
04:22
This is a fantastic piece of work.
79
262989
2112
04:25
This has a climate module, a biosphere module, a global economic model;
80
265125
4103
04:29
it has algorithms, it has the whole room of fantastic accomplishments.
81
269252
5090
04:34
This is what turns us scientists on.
82
274366
2161
04:36
(Laughter)
83
276551
1062
04:37
I mean, this is just a beautiful piece of work?
84
277637
2223
04:39
And I'd just love to spend the whole evening walking this through with you,
85
279884
3806
04:43
but I'll make you disappointed.
86
283714
1944
04:45
I cannot do that.
87
285682
1570
04:47
In fact, the only thing I can do with you is just to assure you
88
287276
3215
04:50
that this is the first time it's done.
89
290515
2247
04:52
Nobody has ever tried to really analytically combine
90
292786
3007
04:55
the Sustainable Development Goals with planetary boundaries.
91
295817
2863
04:58
And we were able to find patterns and really convergent trends
92
298704
5369
05:04
that gives us a lot of confidence in our ability to now project
93
304097
3969
05:08
economic development,
94
308090
1321
05:09
resources use from water, food and energy,
95
309435
3054
05:12
population growth, income per person,
96
312513
2351
05:14
yet along these consistent and systemic pathways.
97
314888
3771
05:18
So, it's the first time we have a robust opportunity
98
318683
2822
05:21
to really explore the futures of ability of attaining the SDGs within PBs.
99
321529
4985
05:26
Now, how do we do this?
100
326538
1184
05:27
Well, look at this.
101
327746
1156
05:28
Here, you have the data coming from the real world,
102
328926
3225
05:32
calibrated from 1970-2015:
103
332175
2604
05:34
100,000 data points around the world,
104
334803
2643
05:37
building on seven regions' ability,
105
337470
2556
05:40
of really picking on all these Sustainable Development Goals.
106
340050
2989
05:43
Now, one example of how we calibrated this,
107
343063
2012
05:45
here you have [data] for Sustainable Development Goals
108
345099
2757
05:47
on eradicating poverty, health, education and food.
109
347880
3537
05:51
And here you have in the bubbles the seven regions of the world,
110
351441
3971
05:55
how they move up until 2015 in our empirical observations
111
355436
4427
05:59
in relation to GDP per capita,
112
359887
2177
06:02
giving these universal convergent trends,
113
362088
2581
06:04
which enabled us to create regressions
114
364693
3085
06:07
that could make us able to do simulations into the future,
115
367802
3655
06:11
all the way until 2050,
116
371481
1957
06:13
showing the ability along the lines here to attain the SDGs.
117
373462
4815
06:18
Now, this gave us the opportunity of doing several scenarios,
118
378734
4633
06:23
testing different possible futures:
119
383391
2515
06:25
business as usual, global transformations,
120
385930
2555
06:28
investment schemes in business, different governance options,
121
388509
3369
06:31
policies, finance --
122
391902
2273
06:34
really, to explore what the future can look like
123
394199
3146
06:37
in our ability to attain the SDGs within PBs.
124
397369
2905
06:40
And the results, I can tell you, really surprised us.
125
400659
3103
06:43
And this will be the first time it's shown.
126
403786
2058
06:45
It should actually not even be referenced outside of this room.
127
405868
3153
06:49
Now, it actually is presented along two axes.
128
409045
3784
06:52
The y-axis here shows our ability to stay within planetary boundaries.
129
412853
3954
06:56
The higher up, the closer you are to the safe operating space.
130
416831
3777
07:00
On the x-axis are the Sustainable Development Goals;
131
420632
2522
07:03
the further to the right, the more of the SDGs we fulfill.
132
423178
3125
07:06
We all want to be in the upper right-hand corner,
133
426327
2418
07:08
the safe and just world for the future.
134
428769
3015
07:11
Now, the point you see there is 1980.
135
431808
2477
07:14
We were in a situation where we actually were in a safe operating space
136
434309
3474
07:17
but not meeting so many of the SDGs.
137
437807
2104
07:19
Here's the trend up until 2015.
138
439935
2972
07:22
So this is the conventional world,
139
442931
1826
07:24
which is actually delivering on an increasing number of SDGs,
140
444781
3115
07:27
lifting millions of people out of poverty,
141
447920
2208
07:30
but doing it at the expense of the safe operating space on earth.
142
450152
4693
07:35
Now, this is the scenario business as usual, into the future.
143
455327
3525
07:38
If we just move on as today,
144
458876
1854
07:40
we will be able to deliver on some of the SDGs,
145
460754
2767
07:43
but we'll do it at the expense of the stability of the earth system.
146
463545
3812
07:48
Now, what if we go faster on economic growth
147
468061
2714
07:50
and really ally on one percent increase per year of income
148
470799
4924
07:55
and an even tripling of the world economy by 2050?
149
475747
3360
07:59
That would give us the following trajectory.
150
479131
2216
08:01
We would, yes, go a little bit further on SDG accomplishments,
151
481371
3819
08:05
but still at the expense of the risk of destabilizing the planet.
152
485214
4294
08:10
But what if we really go harder?
153
490119
2000
08:12
What if we increase our ability to deliver on our promises by 30 percent
154
492143
4701
08:16
across all sectors in society,
155
496868
2642
08:19
from climate to our trade agreements?
156
499534
3243
08:23
A harder scenario would take us a little bit better,
157
503188
4240
08:27
but still, we're failing on the SDGs,
158
507452
2971
08:30
and we are not accomplishing a safe operating space for humanity.
159
510447
3987
08:34
So this really led us to a quite disappointing conclusion,
160
514458
4526
08:39
that we will actually, even if we go conventional futures, fail on the SDGs
161
519008
5449
08:44
and transgress planetary boundaries.
162
524481
1964
08:46
We need some radical thinking.
163
526469
1472
08:47
We need to go into a transformative, disruptive future,
164
527965
4072
08:52
where we start thinking outside of the box.
165
532061
3094
08:55
The modeling and engagement and dialogues enable us to identify
166
535179
3345
08:58
five transformations that could actually potentially take us there.
167
538548
3982
09:02
The first one is to cut emissions by half every decade
168
542554
3218
09:05
along the scientific pathway to Paris,
169
545796
2266
09:08
doubling investments in renewable energy,
170
548086
2422
09:10
creating a global energy democracy,
171
550532
2413
09:12
allowing us to meet several of the SDGs.
172
552969
2650
09:16
The second is a rapid shift towards sustainable food systems,
173
556157
4775
09:20
investing one percent per year in sustainable intensification
174
560956
3872
09:24
and really moving towards implementing and investing in solutions
175
564852
3119
09:27
that we already have available today.
176
567995
2673
09:31
The third is really to shift our development paradigm
177
571286
3948
09:35
and learn from many of the developing countries
178
575258
2238
09:37
that have moved very fast.
179
577520
1259
09:38
What if we could have an economic growth such as in China,
180
578803
3349
09:42
while doing it within the environmental parameters
181
582176
3023
09:45
of an ecological civilization?
182
585223
2150
09:47
Fourth, a redistribution of wealth.
183
587889
2622
09:50
What if we could [agree] that the richest 10 percent
184
590535
3078
09:53
could not allow themselves to amass more than 40 percent, maximum,
185
593637
3240
09:56
of national incomes --
186
596901
1165
09:58
a drastic redistribution of wealth,
187
598090
2132
10:00
reforming the ability of equity across regions?
188
600246
3574
10:03
And finally, fifth, a radical increase in more education, health,
189
603844
3795
10:07
access to work, contraception,
190
607663
1533
10:09
investing largely in women across the world,
191
609220
3285
10:12
allowing us to deliver on SDGs on gender, inequality,
192
612529
4976
10:17
economics and urban development.
193
617529
2485
10:20
Now, if we would push ourselves across all these five --
194
620038
3883
10:23
we tested this, and it would give us an amazing journey
195
623945
5143

towards the safe and just operating space on earth.

It shows us that even with a conservative, empirically based,
197
633445
4207
10:37
complex system dynamics model,
198
637676
1772
10:39
we are at a state where we can actually think of transformations
199
639472
3991
10:43
over the next 12 years and beyond
200
643487
1916
10:45
that can take us up into the safe operating space
201
645427
3205
10:48
and deliver on aspirational social and economic goals.
202
648656
3470
10:52
This is actually quite uplifting,
203
652598
2701
10:55
despite the fact that we're not moving along this trajectory.
204
655323
3309
10:58
So, in summary:
205
658656
1407
11:00
we now, three years into the operational delivery on the SDGs,
206
660087
4161
11:04
must draw a line
207
664272
2107
11:06
and conclude that we're not delivering on our promises,
208
666403
3472
11:09
and not only that, we're running the risks
209
669899
2472
11:12
of future generations having an even tougher ability,
210
672395
3327
11:15
because of the risk of pushing the earth system beyond tipping points.
211
675746
3643
11:19
In fact, we are facing even a risk of a hothouse earth,
212
679413
3817
11:23
where we will undermine and create geopolitical instabilities
213
683254
3611
11:26
that could actually make life even more tough
214
686889
2319
11:29
for billions of people on earth.
215
689232
2414
11:31
This, in all honesty, really, really scares me.
216
691670
3637
11:35
But that's also why I'm standing here tonight,
217
695998
2578
11:38
because the window of success is still open.
218
698600
3118
11:41
The earth system is still resilient.
219
701742
2441
11:44
She is still providing us with ecosystem services and functions
220
704207
3831
11:48
that can allow us a transition back into a safe operating space.
221
708062
3370
11:51
But we need radically different thinking.
222
711456
2562
11:54
We need to see this as an incredible wake-up call
223
714042
3963
11:58
but also an opportunity for transformative change,
224
718029
2755
12:00
where we shift gears
225
720808
1300
12:02
and really start thinking of the SDGs as a transformative agenda
226
722132
3451
12:05
within a safe operating space on earth.
227
725607
2305
12:07
In other words, we can build a safe and just world.
228
727936
4232
12:12
We just have to really, really get on with it.
229
732192
3006
12:15
And let's do it. Thank you.
