--> 00:00:25,400 It's a pleasure to be here. 10 00:00:25,400 --> 00:00:27,105 So I'm going to talk about Greenometry. 11 00:00:27,105 --> 00:00:31,500 Greenometry is a new nonprofit that enlists the market 12 00:00:31,500 --> 00:00:33,420 in solving climate change. 13 00:00:33,420 --> 00:00:36,510 Enlisting the market means that we 14 00:00:36,510 --> 00:00:38,610 want to allow everyone to know the carbon 15 00:00:38,610 --> 00:00:40,200 footprint of everything. 16 00:00:40,200 --> 00:00:42,280 And for that, we need to fix carbon footprint. 17 00:00:42,280 --> 00:00:44,650 So that's what I want to talk about. 18 00:00:44,650 --> 00:00:47,730 And it's not a secret to you that the country 19 00:00:47,730 --> 00:00:50,340 took like a different trajectory than reality. 20 00:00:53,050 --> 00:00:56,220 16 of the last 17 years were the hottest on record. 21 00:00:56,220 --> 00:01:01,080 And then policy is going on the opposite direction. 22 00:01:01,080 --> 00:01:06,450 So if we would expect the emitters, the supply side, 23 00:01:06,450 --> 00:01:09,700 to be a major part of the solution, 24 00:01:09,700 --> 00:01:12,180 they have less incentive to be a major part of the solution 25 00:01:12,180 --> 00:01:14,910 right now because they're not forced to. 26 00:01:14,910 --> 00:01:18,570 So the power that we want to engage is the market. 27 00:01:18,570 --> 00:01:20,820 And if you think about it, the market 28 00:01:20,820 --> 00:01:24,360 is maybe the largest force on the planet. 29 00:01:24,360 --> 00:01:28,620 Think about nearly 7 billion buyers, trillions 30 00:01:28,620 --> 00:01:29,970 of dollars of investors. 31 00:01:29,970 --> 00:01:34,080 About 400 companies control 70% of the commodity trading. 32 00:01:34,080 --> 00:01:37,620 Think about the decision power these entities have. 33 00:01:37,620 --> 00:01:40,800 Universities, every university, including this one, 34 00:01:40,800 --> 00:01:42,900 has a climate action plan. 35 00:01:42,900 --> 00:01:46,170 Cities, about 70% of the carbon emission on the planet 36 00:01:46,170 --> 00:01:49,210 is related to cities and so on. 37 00:01:49,210 --> 00:01:51,900 So we want to engage the market. 38 00:01:51,900 --> 00:01:54,390 The oxygen of markets is metrics. 39 00:01:54,390 --> 00:01:57,600 Markets need to be run by numbers. 40 00:01:57,600 --> 00:02:00,480 And the problem is that carbon footprint is broken. 41 00:02:00,480 --> 00:02:03,120 The system doesn't add up. 42 00:02:03,120 --> 00:02:06,360 If I would ask any of you what the carbon footprint of nearly 43 00:02:06,360 --> 00:02:08,610 anything, you wouldn't know. 44 00:02:08,610 --> 00:02:09,780 It's so vague. 45 00:02:09,780 --> 00:02:11,700 So we need to fix carbon footprint 46 00:02:11,700 --> 00:02:14,870 to activate the market to be part of the solution. 47 00:02:14,870 --> 00:02:17,800 And I want to talk more about this point. 48 00:02:17,800 --> 00:02:21,260 So if you look at how many searches 49 00:02:21,260 --> 00:02:24,100 are done for the term carbon footprint on Google, 50 00:02:24,100 --> 00:02:27,380 you would see the rise and fall of carbon footprint. 51 00:02:27,380 --> 00:02:29,470 It was high and then went low. 52 00:02:29,470 --> 00:02:32,730 If you look at newspaper articles, it also went lower. 53 00:02:32,730 --> 00:02:36,210 On the other hand, academic publications went up. 54 00:02:36,210 --> 00:02:40,220 So there's a gap between knowledge and actual public 55 00:02:40,220 --> 00:02:42,470 engagement in the actual information of what 56 00:02:42,470 --> 00:02:44,030 is a carbon footprint. 57 00:02:44,030 --> 00:02:46,115 And part of the mission of Greenometry, 58 00:02:46,115 --> 00:02:47,990 in order to allow everyone to know the carbon 59 00:02:47,990 --> 00:02:49,880 footprint of everything, is to bridge 60 00:02:49,880 --> 00:02:54,630 this gap between knowledge and actual behavior. 61 00:02:54,630 --> 00:02:57,920 So what makes a good metric? 62 00:02:57,920 --> 00:03:00,320 So how do we build a good carbon footprint? 63 00:03:00,320 --> 00:03:04,050 To answer this question, a few years ago, 64 00:03:04,050 --> 00:03:07,310 I went to meet Daniel Kahneman, the Nobel Prize 65 00:03:07,310 --> 00:03:09,500 winner in Economics. 66 00:03:09,500 --> 00:03:13,100 And we had a long conversation about what makes a good metric. 67 00:03:13,100 --> 00:03:16,650 And essentially you need to think of two components. 68 00:03:16,650 --> 00:03:17,690 One is simplicity. 69 00:03:17,690 --> 00:03:18,720 It needs to be simple. 70 00:03:18,720 --> 00:03:21,500 We need to be able to make estimations, 71 00:03:21,500 --> 00:03:24,980 to make back-of-the-envelope quantitative reasoning. 72 00:03:24,980 --> 00:03:26,285 And you need accuracy. 73 00:03:27,780 --> 00:03:30,770 In most decisions in life, we use this ability 74 00:03:30,770 --> 00:03:31,700 to make estimations. 75 00:03:31,700 --> 00:03:32,840 We estimate distances. 76 00:03:32,840 --> 00:03:34,522 We estimate price. 77 00:03:34,522 --> 00:03:36,230 We estimate the probability that the jury 78 00:03:36,230 --> 00:03:39,230 will be more in our favor. 79 00:03:39,230 --> 00:03:41,210 We do those estimations all the time. 80 00:03:41,210 --> 00:03:43,280 Someone on a diet can estimate calories 81 00:03:43,280 --> 00:03:44,840 with pretty good accuracy. 82 00:03:44,840 --> 00:03:46,520 If you like sports, then you would 83 00:03:46,520 --> 00:03:48,740 know that an Olympic athlete will run 84 00:03:48,740 --> 00:03:51,796 100 meters at about 10 seconds. 85 00:03:51,796 --> 00:03:53,420 But then you need the accuracy in order 86 00:03:53,420 --> 00:03:55,640 to have a race to the top. 87 00:03:55,640 --> 00:03:56,330 Who is the best? 88 00:03:56,330 --> 00:03:59,330 It's fractions of seconds. 89 00:03:59,330 --> 00:04:01,460 And if you think about carbon footprint 90 00:04:01,460 --> 00:04:04,940 and you want to compare two products that are the same, 91 00:04:04,940 --> 00:04:07,190 two running shoes, you need the accuracy 92 00:04:07,190 --> 00:04:09,180 in order to determine between the two of them. 93 00:04:09,180 --> 00:04:11,780 So you need simplicity, and you need accuracy. 94 00:04:11,780 --> 00:04:14,030 The simplicity is this quantitative reasoning 95 00:04:14,030 --> 00:04:17,480 or quantitative intuition, which is sort of vague or sort 96 00:04:17,480 --> 00:04:18,680 of elusive. 97 00:04:18,680 --> 00:04:20,209 But quantitative intuition, the way 98 00:04:20,209 --> 00:04:23,570 to build it, according to this beautiful book, Thinking 99 00:04:23,570 --> 00:04:28,840 of Fast and Slow, is by thinking about two things, practice 100 00:04:28,840 --> 00:04:30,020 and consistency. 101 00:04:30,020 --> 00:04:33,620 If you have a consistent signal, like the calories of food, 102 00:04:33,620 --> 00:04:37,280 and you think about it daily, it becomes intuitive. 103 00:04:37,280 --> 00:04:40,190 So how well are we doing on carbon footprint? 104 00:04:40,190 --> 00:04:43,790 And the easiest thing to think about is a gallon of gas. 105 00:04:43,790 --> 00:04:45,740 This is like the one major decision 106 00:04:45,740 --> 00:04:49,170 that we really make daily, put gas in our car. 107 00:04:49,170 --> 00:04:51,920 It's very energy dense, and this is like the largest emission 108 00:04:51,920 --> 00:04:52,990 that we do. 109 00:04:52,990 --> 00:04:54,950 And about two hours a year, we have 110 00:04:54,950 --> 00:04:57,770 nothing better to do, just fuel our cars and look at the price. 111 00:04:57,770 --> 00:05:00,020 That's why the price is presented 112 00:05:00,020 --> 00:05:02,030 with fractions of cents. 113 00:05:02,030 --> 00:05:06,320 So how well can we tell the carbon content, 114 00:05:06,320 --> 00:05:08,750 how much the carbon emission of a gallon of gas? 115 00:05:08,750 --> 00:05:11,120 So we were curious about this question. 116 00:05:11,120 --> 00:05:14,300 And with a friend at Northeastern University, 117 00:05:14,300 --> 00:05:20,120 we've asked 300 people, how much carbon they emit when they put 118 00:05:20,120 --> 00:05:22,950 one gallon of gas in their car? 119 00:05:22,950 --> 00:05:26,600 The variation of the answer was two to three orders 120 00:05:26,600 --> 00:05:28,790 of magnitude between grams and tons, 121 00:05:28,790 --> 00:05:30,940 sort of, or tens of grams of tons. 122 00:05:30,940 --> 00:05:33,350 Think about going into a Starbucks wanting 123 00:05:33,350 --> 00:05:35,270 to buy a cup of coffee and don't know 124 00:05:35,270 --> 00:05:40,100 if it's going to cost you $300 or 0.3 cents. 125 00:05:40,100 --> 00:05:41,880 That's how bad we are. 126 00:05:41,880 --> 00:05:44,540 So what does the market have to fix this problem? 127 00:05:44,540 --> 00:05:49,610 If we look at numbers in an anecdotal way, it's adjectives. 128 00:05:49,610 --> 00:05:51,980 Grams, tons, everything is confused. 129 00:05:51,980 --> 00:05:54,740 It's either that we don't care, or that we're 130 00:05:54,740 --> 00:05:56,720 too lazy to actually do the math, 131 00:05:56,720 --> 00:05:59,630 or something else is wrong in the system that we want to fix. 132 00:05:59,630 --> 00:06:02,510 By the way, we were so surprised by this result, 133 00:06:02,510 --> 00:06:05,810 that we asked 1,000 people and got the same result. 134 00:06:05,810 --> 00:06:07,490 This is a log scale. 135 00:06:07,490 --> 00:06:10,910 The x-axis are questions that are also 136 00:06:10,910 --> 00:06:13,640 relevant to the daily life, like what's the weight of the car? 137 00:06:13,640 --> 00:06:14,880 You don't lift your car. 138 00:06:14,880 --> 00:06:17,300 And still it's orders of magnitude better estimation 139 00:06:17,300 --> 00:06:18,260 than carbon. 140 00:06:18,260 --> 00:06:23,120 Something is fundamentally wrong with carbon footprint. 141 00:06:23,120 --> 00:06:29,350 If you put the same data in different carbon calculators 142 00:06:29,350 --> 00:06:34,200 online, the result varies by 300%. 143 00:06:34,200 --> 00:06:37,880 So MIT wants to reduce its carbon footprint by, let's say, 144 00:06:37,880 --> 00:06:39,420 30%. 145 00:06:39,420 --> 00:06:43,310 And we use a system with uncertainty of 300%. 146 00:06:43,310 --> 00:06:47,570 So where is the math? 147 00:06:47,570 --> 00:06:50,200 And that obviously gives rise to all kinds of anecdotes. 148 00:06:50,200 --> 00:06:52,970 We can see newspaper articles about saving the planet 149 00:06:52,970 --> 00:06:57,620 by sending less emails because an email is 0.3 grams. 150 00:06:57,620 --> 00:07:00,360 And in the world of anecdotes of adjectives, a gram and a ton 151 00:07:00,360 --> 00:07:01,580 is the same. 152 00:07:01,580 --> 00:07:03,600 So you don't bother to do the math. 153 00:07:03,600 --> 00:07:07,779 It's 0.00003 a gallon of gas, right? 154 00:07:07,779 --> 00:07:09,320 If you look at the way that companies 155 00:07:09,320 --> 00:07:11,550 are handling this problem, look at Timberland. 156 00:07:11,550 --> 00:07:14,540 Timberland is probably one of the companies 157 00:07:14,540 --> 00:07:18,170 that were the best geared to have a good sustainability 158 00:07:18,170 --> 00:07:19,330 program. 159 00:07:19,330 --> 00:07:22,600 They had a committed CEO, committed shareholders. 160 00:07:22,600 --> 00:07:25,220 The customers are the outdoor people. 161 00:07:25,220 --> 00:07:26,330 So it's better. 162 00:07:26,330 --> 00:07:29,030 So they wanted to reduce their carbon footprint. 163 00:07:29,030 --> 00:07:31,660 And they built great sustainability reports. 164 00:07:31,660 --> 00:07:34,200 They were prize winners in terms of the sustainability 165 00:07:34,200 --> 00:07:35,260 performance. 166 00:07:35,260 --> 00:07:37,580 The way carbon footprint is built, 167 00:07:37,580 --> 00:07:43,160 so they looked at only their own site 168 00:07:43,160 --> 00:07:45,350 emissions, what they're responsible for, 169 00:07:45,350 --> 00:07:48,740 which turns out to be about 4% of the total emission. 170 00:07:48,740 --> 00:07:50,570 The other about 20% is electricity, 171 00:07:50,570 --> 00:07:52,580 and then the rest is supply chain. 172 00:07:52,580 --> 00:07:57,510 So they did phenomenal work reducing 20% of the 4%. 173 00:07:57,510 --> 00:08:00,170 And that's the best company. 174 00:08:00,170 --> 00:08:03,060 And then they said, let's engage our customers, 175 00:08:03,060 --> 00:08:05,270 our outdoor people. 176 00:08:05,270 --> 00:08:11,040 So they had a label, a product label on the shoes. 177 00:08:11,040 --> 00:08:15,110 An average Timberland shoe is about two kilowatt hour. 178 00:08:15,110 --> 00:08:16,850 The accuracy was such that all the shoes 179 00:08:16,850 --> 00:08:18,290 were two kilowatt hour. 180 00:08:18,290 --> 00:08:20,810 And who is the consumer that knows 181 00:08:20,810 --> 00:08:23,820 what's a kilowatt hour in the context of a shoe? 182 00:08:23,820 --> 00:08:26,100 What buying decisions it make? 183 00:08:26,100 --> 00:08:29,180 So after 18 months of building this program, 184 00:08:29,180 --> 00:08:31,980 they had the label, and they took it out. 185 00:08:31,980 --> 00:08:34,760 So something is fundamentally wrong with the way 186 00:08:34,760 --> 00:08:38,150 we try to fix the problem of climate change 187 00:08:38,150 --> 00:08:41,000 through the market because the market doesn't have metrics, 188 00:08:41,000 --> 00:08:42,642 because carbon footprint doesn't work. 189 00:08:42,642 --> 00:08:44,600 So let's look at how carbon footprint is built. 190 00:08:44,600 --> 00:08:46,460 What are we doing? 191 00:08:46,460 --> 00:08:49,490 So it's divided to a few scopes. 192 00:08:49,490 --> 00:08:52,550 Scope one is what we do on site. 193 00:08:52,550 --> 00:08:54,980 Scope two is the electricity that we purchase. 194 00:08:54,980 --> 00:08:59,180 And it's divided to scope to avoid a double counting. 195 00:08:59,180 --> 00:09:01,160 Then supply chain is hugely complex. 196 00:09:01,160 --> 00:09:02,320 It is scope 3. 197 00:09:02,320 --> 00:09:04,310 It is complex because how do I know 198 00:09:04,310 --> 00:09:07,850 what the supply in China or in Vietnam or in Malaysia 199 00:09:07,850 --> 00:09:11,420 is doing, and how do I allocate their emissions 200 00:09:11,420 --> 00:09:13,255 to the different other customers? 201 00:09:13,255 --> 00:09:15,380 And then there are things that are really important 202 00:09:15,380 --> 00:09:19,190 and are not included, like water or land use. 203 00:09:19,190 --> 00:09:23,060 Next step is to convert this consumption to a metric, which 204 00:09:23,060 --> 00:09:25,010 is tons of CO2. 205 00:09:25,010 --> 00:09:27,680 And then we need to read the tons of CO2. 206 00:09:27,680 --> 00:09:30,830 So what needs fixing? 207 00:09:30,830 --> 00:09:33,380 The on-site emission is pretty well. 208 00:09:33,380 --> 00:09:34,440 We can measure it. 209 00:09:34,440 --> 00:09:38,360 We can measure our natural gas, that you'll hear about soon. 210 00:09:38,360 --> 00:09:42,380 Everything that's on site is OK. 211 00:09:42,380 --> 00:09:45,890 Electricity is a very complex problem 212 00:09:45,890 --> 00:09:49,850 because we need to solve the inverse problem. 213 00:09:49,850 --> 00:09:52,270 I'm here consuming electricity in this room. 214 00:09:52,270 --> 00:09:54,710 Some of it might come from the co-gen plant down the road. 215 00:09:54,710 --> 00:09:58,280 Some of it might come from New England ISO, from solar panels, 216 00:09:58,280 --> 00:09:59,660 from Hydro-Québec. 217 00:09:59,660 --> 00:10:01,670 How do I solve this problem? 218 00:10:01,670 --> 00:10:03,650 It's a problem that wasn't solved yet. 219 00:10:03,650 --> 00:10:05,495 Supply chain, as I said, is hugely complex. 220 00:10:05,495 --> 00:10:06,930 It needs to be fixed. 221 00:10:06,930 --> 00:10:09,240 And then water needs to be fixed. 222 00:10:09,240 --> 00:10:12,510 And then I need a metric which is intuitive. 223 00:10:12,510 --> 00:10:15,440 So we won't talk with those anecdotes. 224 00:10:15,440 --> 00:10:17,870 So it's a hugely complex system, because 225 00:10:17,870 --> 00:10:21,020 agricultural and gradual waste and where 226 00:10:21,020 --> 00:10:24,620 everything comes from is-- 227 00:10:24,620 --> 00:10:28,430 solving for the infrastructure is very complex. 228 00:10:28,430 --> 00:10:31,860 And as I mentioned, we need to solve the inverse problem. 229 00:10:31,860 --> 00:10:35,480 We're in the end receiving electricity. 230 00:10:35,480 --> 00:10:37,190 And we need to work out all the way 231 00:10:37,190 --> 00:10:39,530 upstream to see where this electricity is coming from. 232 00:10:39,530 --> 00:10:41,750 And electricity is one example. 233 00:10:41,750 --> 00:10:46,340 And the other problem is that your generation is busy doing 234 00:10:46,340 --> 00:10:48,590 something else, clicking ads. 235 00:10:48,590 --> 00:10:52,820 The best data scientists in this country 236 00:10:52,820 --> 00:10:56,630 are busy doing not solving social problems, 237 00:10:56,630 --> 00:10:59,340 but solving other problem. 238 00:10:59,340 --> 00:11:01,670 So part of the things that we're doing with Greenometry 239 00:11:01,670 --> 00:11:05,060 is just trying to build a tech company, nonprofit, 240 00:11:05,060 --> 00:11:07,400 nonprofit that acts like a tech company. 241 00:11:07,400 --> 00:11:08,790 But the success criteria, instead 242 00:11:08,790 --> 00:11:10,290 of being building shareholder value, 243 00:11:10,290 --> 00:11:17,070 it will be just abated CO2, just reducing a carbon footprint. 244 00:11:17,070 --> 00:11:22,255 So we want to fix the electricity, the supply chain, 245 00:11:22,255 --> 00:11:24,380 obviously with the others-- we cannot do everything 246 00:11:24,380 --> 00:11:28,290 ourselves-- water, and have a very simple unit, 247 00:11:28,290 --> 00:11:29,990 which we call an energy point. 248 00:11:29,990 --> 00:11:33,680 An energy point is simply 10 kilograms of CO2, very simple. 249 00:11:33,680 --> 00:11:36,200 But it's equivalent to one gallon of gas. 250 00:11:36,200 --> 00:11:41,865 So if I bought a shoe that is three energy points. 251 00:11:41,865 --> 00:11:44,240 I know that it's equivalent to about three gallons of gas 252 00:11:44,240 --> 00:11:47,180 in my car, start building this intuition. 253 00:11:47,180 --> 00:11:49,880 And it's a huge path, and we're in the beginning of this road 254 00:11:49,880 --> 00:11:53,360 because creating a new language, a new quantitative way 255 00:11:53,360 --> 00:11:56,310 of thinking about things is a huge path. 256 00:11:56,310 --> 00:11:59,750 So let me show you a few ways that we've handled 257 00:11:59,750 --> 00:12:03,890 this problem with data science. 258 00:12:03,890 --> 00:12:07,670 So thinking about electricity, the carbon 259 00:12:07,670 --> 00:12:10,280 footprint of electricity is measured in this country 260 00:12:10,280 --> 00:12:11,090 right now. 261 00:12:11,090 --> 00:12:13,400 And the US, by the way, is leading in the world. 262 00:12:13,400 --> 00:12:14,990 And God bless the EPA, and I hope 263 00:12:14,990 --> 00:12:19,770 that they'll exist and be safe for a long time. 264 00:12:19,770 --> 00:12:24,380 So the EPA divides the US to 24 regions, 265 00:12:24,380 --> 00:12:28,280 provides an annual average information, 266 00:12:28,280 --> 00:12:29,600 with two years delay. 267 00:12:29,600 --> 00:12:33,020 So just two weeks ago, we got the 2014 information, 268 00:12:33,020 --> 00:12:34,740 which is an annual average. 269 00:12:34,740 --> 00:12:39,580 Now, as we know, electricity is traded in 10 minutes intervals. 270 00:12:39,580 --> 00:12:42,350 And there's about 20,000 power plants in the US. 271 00:12:42,350 --> 00:12:44,450 So it's a hugely complex problem that needs 272 00:12:44,450 --> 00:12:48,410 to be solved with more details. 273 00:12:48,410 --> 00:12:51,380 So we've developed a data science model, where 274 00:12:51,380 --> 00:12:53,010 we didn't solve it entirely. 275 00:12:53,010 --> 00:12:54,150 We just improved it. 276 00:12:54,150 --> 00:12:56,690 And then published and made the data available. 277 00:12:56,690 --> 00:13:01,070 We improved the cadence from annual to monthly or hourly-- 278 00:13:01,070 --> 00:13:03,260 it depends on the data available from the power 279 00:13:03,260 --> 00:13:07,070 plants-- and the spatial resolution from 24 to 138. 280 00:13:07,070 --> 00:13:08,480 So it's progress. 281 00:13:08,480 --> 00:13:12,990 And we're not providing this information to all developers 282 00:13:12,990 --> 00:13:15,830 through an API that will be launched next week. 283 00:13:15,830 --> 00:13:18,080 So every developer that would like 284 00:13:18,080 --> 00:13:21,800 to develop an app that uses electricity 285 00:13:21,800 --> 00:13:25,460 can use our information and develop cool apps. 286 00:13:25,460 --> 00:13:27,620 Because the developers market is kind of 287 00:13:27,620 --> 00:13:31,640 stagnant in carbon footprint if the data is so boring 288 00:13:31,640 --> 00:13:36,070 and in such a low cadence. 289 00:13:36,070 --> 00:13:38,510 Another example of solving carbon footprint 290 00:13:38,510 --> 00:13:41,421 is how to introduce water into carbon footprint. 291 00:13:41,421 --> 00:13:42,920 So as someone who grew up in Israel, 292 00:13:42,920 --> 00:13:45,272 I'm very sensitive to the water issue. 293 00:13:45,272 --> 00:13:46,730 Just like you have college football 294 00:13:46,730 --> 00:13:50,100 in the newspaper in the US, you have water issues in Israel, 295 00:13:50,100 --> 00:13:51,650 along with other issues. 296 00:13:51,650 --> 00:13:56,120 So the way we developed it, we looked at the energy intensity 297 00:13:56,120 --> 00:13:57,030 of water. 298 00:13:57,030 --> 00:14:00,330 How much energy is invested in water in each location? 299 00:14:00,330 --> 00:14:02,330 And then what's the source of this energy, which 300 00:14:02,330 --> 00:14:03,680 is the previous problem? 301 00:14:03,680 --> 00:14:08,330 And together we mapped water into energy. 302 00:14:08,330 --> 00:14:10,010 Now, there's a huge remaining work 303 00:14:10,010 --> 00:14:12,740 to do because it's very local. 304 00:14:12,740 --> 00:14:15,680 Last summer farmers in Massachusetts 305 00:14:15,680 --> 00:14:17,904 had to truck water into their fields. 306 00:14:17,904 --> 00:14:19,070 How do you account for that? 307 00:14:19,070 --> 00:14:20,990 How do you account for scarcity? 308 00:14:20,990 --> 00:14:23,390 So what we do is we try to solve this problem, 309 00:14:23,390 --> 00:14:27,650 publish papers in academic journals or other places, 310 00:14:27,650 --> 00:14:29,600 engage into a dialogue. 311 00:14:29,600 --> 00:14:32,630 So let's see how the world, if we have this carbon footprint 312 00:14:32,630 --> 00:14:34,730 2.0, if we have like a quantitative way 313 00:14:34,730 --> 00:14:39,570 to think about climate, how the world looks like. 314 00:14:39,570 --> 00:14:43,400 So think about the possibility that each of you 315 00:14:43,400 --> 00:14:46,940 will have a carbon budget. 316 00:14:46,940 --> 00:14:49,610 In very simple terms, EP equivalent to a gallon of gas, 317 00:14:49,610 --> 00:14:51,109 as we've discussed. 318 00:14:51,109 --> 00:14:52,400 So you have a household budget. 319 00:14:52,400 --> 00:14:54,233 You have a city budget, a university budget, 320 00:14:54,233 --> 00:14:56,270 a company budget in your EP. 321 00:14:56,270 --> 00:14:58,200 And you have a context. 322 00:14:58,200 --> 00:15:00,930 If you're in Texas in the summer, 323 00:15:00,930 --> 00:15:05,390 it will be about 200 EPs, equivalent to a gallon of gas, 324 00:15:05,390 --> 00:15:10,640 or 2,000 kilos of CO2 per month for your household. 325 00:15:10,640 --> 00:15:14,180 And part of it is water just because a lot of energy 326 00:15:14,180 --> 00:15:15,730 goes into water. 327 00:15:15,730 --> 00:15:17,750 In New England in the winter will be less. 328 00:15:17,750 --> 00:15:20,199 But it can be very specific. 329 00:15:20,199 --> 00:15:21,740 And you start thinking quantitatively 330 00:15:21,740 --> 00:15:23,360 about your impact. 331 00:15:23,360 --> 00:15:25,350 So if you have, just like we've discussed, 332 00:15:25,350 --> 00:15:30,500 a home energy device, so a home energy device, like a sense, 333 00:15:30,500 --> 00:15:33,240 will give you a reading in kilowatt hours. 334 00:15:33,240 --> 00:15:35,300 So we have, let's say, 29 kilowatt hours. 335 00:15:35,300 --> 00:15:38,510 It doesn't have any carbon context 336 00:15:38,510 --> 00:15:42,470 unless you translate it to what happens on the grid right now. 337 00:15:42,470 --> 00:15:45,450 So using our API, you can have this translation. 338 00:15:45,450 --> 00:15:47,660 So you can see that if I'm in Brookline 339 00:15:47,660 --> 00:15:50,510 and I have in my energy sources solar, 340 00:15:50,510 --> 00:15:54,470 this 29 kilowatt hours is less than 1 EP. 341 00:15:54,470 --> 00:15:57,050 But on the other hand, if I'm in Wyoming 342 00:15:57,050 --> 00:16:00,500 and my electricity source happens to be coal, 343 00:16:00,500 --> 00:16:05,030 it can be significantly more, maybe five times more. 344 00:16:05,030 --> 00:16:06,950 So I can have a budget that allows 345 00:16:06,950 --> 00:16:08,300 me to think quantitatively. 346 00:16:08,300 --> 00:16:10,850 Just like a diet, I think about calories, 347 00:16:10,850 --> 00:16:13,700 think about my carbon footprint. 348 00:16:13,700 --> 00:16:16,610 If I happen to drive a Tesla, so the Tesla 349 00:16:16,610 --> 00:16:18,350 doesn't have an MPG rating because it 350 00:16:18,350 --> 00:16:20,270 doesn't consume gasoline. 351 00:16:20,270 --> 00:16:24,170 But if you think about this conversion of 10 kilograms 352 00:16:24,170 --> 00:16:28,250 of CO2 is a gallon of gas, so I can convert the same 10 353 00:16:28,250 --> 00:16:31,670 kilograms of CO2 to the energy sources that 354 00:16:31,670 --> 00:16:33,830 feed the Tesla right now. 355 00:16:33,830 --> 00:16:36,020 Instead of having just watt hours 356 00:16:36,020 --> 00:16:38,690 per mile, which is the reading on the Tesla dashboard, 357 00:16:38,690 --> 00:16:40,610 I can have the Tesla MPG. 358 00:16:40,610 --> 00:16:43,430 So I can actually compare the Tesla to other cars. 359 00:16:43,430 --> 00:16:46,760 Tesla versus Lexus, if I'm in Wyoming 360 00:16:46,760 --> 00:16:49,120 and I have an energy-intensive grid, 361 00:16:49,120 --> 00:16:51,230 actually the Lexus is better. 362 00:16:51,230 --> 00:16:54,140 If I'm in California, most of California 363 00:16:54,140 --> 00:16:57,010 or most of Massachusetts, actually Tesla is better. 364 00:16:57,010 --> 00:16:59,510 And if I have a cleaner power source, obviously it's better. 365 00:16:59,510 --> 00:17:00,801 But everything is quantitative. 366 00:17:00,801 --> 00:17:02,480 It's not anecdotal. 367 00:17:02,480 --> 00:17:04,920 It's the actions actually add up. 368 00:17:04,920 --> 00:17:07,339 So I can see how much money I need 369 00:17:07,339 --> 00:17:11,339 to invest per unit of carbon. 370 00:17:11,339 --> 00:17:13,700 One of my favorite examples is the running shoe. 371 00:17:13,700 --> 00:17:16,579 If I buy and Nike, Nike is very proud of the Flyknit 372 00:17:16,579 --> 00:17:18,290 because they have this great innovation 373 00:17:18,290 --> 00:17:21,349 of having one thread that ties the entire shoe. 374 00:17:21,349 --> 00:17:25,160 But the Flyknit reduces about 20% 375 00:17:25,160 --> 00:17:29,120 of the material in the shoe, which is a huge accomplishment. 376 00:17:29,120 --> 00:17:31,550 But if you think about the climate impact 377 00:17:31,550 --> 00:17:33,770 and you add the energy and water, which 378 00:17:33,770 --> 00:17:37,790 are pretty similar to the competing issue, the Pegasus, 379 00:17:37,790 --> 00:17:39,290 the accomplishment is not that huge. 380 00:17:39,290 --> 00:17:42,270 It's like about, let's say, 10%. 381 00:17:42,270 --> 00:17:45,320 What's interesting, especially with those conversations 382 00:17:45,320 --> 00:17:48,770 on domestic manufacturing, is that if I 383 00:17:48,770 --> 00:17:50,760 will know the entire infrastructure, 384 00:17:50,760 --> 00:17:52,950 I'll solve this reverse problem and understand 385 00:17:52,950 --> 00:17:57,207 the infrastructure, and look at what does it 386 00:17:57,207 --> 00:17:58,790 mean for the climate, not financially? 387 00:17:58,790 --> 00:18:05,120 To move manufracturing to Portland, Oregon, Nike's 388 00:18:05,120 --> 00:18:08,810 headquarter, I will reduce the impact of these shoes 389 00:18:08,810 --> 00:18:11,990 significantly, by about 30%, because they have cleaner 390 00:18:11,990 --> 00:18:14,150 water and cleaner power. 391 00:18:14,150 --> 00:18:15,750 And I have this quantitative notion. 392 00:18:15,750 --> 00:18:18,526 I step into a shop, want to buy a running shoe. 393 00:18:18,526 --> 00:18:20,150 And I know that it's about three energy 394 00:18:20,150 --> 00:18:23,660 points, which is equivalent to about three gallons of gas. 395 00:18:23,660 --> 00:18:28,730 So I can know how much it relates to my other activities. 396 00:18:28,730 --> 00:18:30,590 I start having a budget. 397 00:18:30,590 --> 00:18:32,240 Just like people that are athletes 398 00:18:32,240 --> 00:18:34,190 that run their lives with a Fitbit, 399 00:18:34,190 --> 00:18:35,460 I can have a "carbon bit." 400 00:18:35,460 --> 00:18:37,760 There are endless possibilities. 401 00:18:37,760 --> 00:18:41,530 And I'll end with the last example, investors. 402 00:18:41,530 --> 00:18:43,090 There are trillions of dollars that 403 00:18:43,090 --> 00:18:45,440 claim to be impact investors. 404 00:18:45,440 --> 00:18:48,110 And they're thirsty for data. 405 00:18:48,110 --> 00:18:49,820 For one example, imagine that you want 406 00:18:49,820 --> 00:18:52,280 to invest in a solar project. 407 00:18:52,280 --> 00:19:02,000 Now, a solar project, if you take a mono-silicon panels 408 00:19:02,000 --> 00:19:05,270 produced in China, installed in a relatively clean grid 409 00:19:05,270 --> 00:19:10,250 in California, it can take up to nine years just 410 00:19:10,250 --> 00:19:13,220 to pay back the carbon. 411 00:19:13,220 --> 00:19:18,975 If the lifetime of these panels is 20 years, it's nearly half. 412 00:19:18,975 --> 00:19:22,250 It's a serious time just paying back the carbon. 413 00:19:22,250 --> 00:19:26,540 So the MPG of solar using Carbon Footprint 2.0 414 00:19:26,540 --> 00:19:27,860 can be calculated. 415 00:19:27,860 --> 00:19:30,200 On the other hand, if I take cadmium telluride produced 416 00:19:30,200 --> 00:19:32,990 in Malaysia installed in Wyoming, 417 00:19:32,990 --> 00:19:35,340 it returns its carbon within two years. 418 00:19:35,340 --> 00:19:38,010 So it won't drive the decisions, but it needs 419 00:19:38,010 --> 00:19:40,100 to be an additional factor. 420 00:19:40,100 --> 00:19:41,850 The economics will drive the decisions. 421 00:19:41,850 --> 00:19:44,310 But if I have a carbon budget, I start 422 00:19:44,310 --> 00:19:46,960 thinking in numbers and not in adjectives. 423 00:19:46,960 --> 00:19:48,900 So these things start to be meaningful. 424 00:19:48,900 --> 00:19:53,640 Because today, investors can calculate their financial ROI. 425 00:19:53,640 --> 00:19:56,160 They're totally lost on their social ROI. 426 00:19:56,160 --> 00:19:56,970 What's the climate? 427 00:19:56,970 --> 00:19:57,810 Everything is renewable. 428 00:19:57,810 --> 00:19:58,530 Everything is great. 429 00:19:58,530 --> 00:20:00,446 And we're having a great party, and everything 430 00:20:00,446 --> 00:20:03,520 is green except the planet. 431 00:20:03,520 --> 00:20:08,320 So only three points that I want you to remember. 432 00:20:08,320 --> 00:20:12,810 We must engage the market because the polluters 433 00:20:12,810 --> 00:20:15,600 will be less engaged. 434 00:20:15,600 --> 00:20:18,540 The market lives on metrics. 435 00:20:18,540 --> 00:20:22,330 And to have a good metric, we need to fix carbon footprint. 436 00:20:22,330 --> 00:20:26,940 So the privilege of knowledge brings a duty to act. 437 00:20:26,940 --> 00:20:28,740 So let's all act about it. 438 00:20:28,740 --> 00:20:30,747 Thank you very much. 439 00:20:30,747 --> 00:20:32,703 [APPLAUSE] 440 00:20:42,972 --> 00:20:44,928 AUDIENCE: So I have solar panels, 441 00:20:44,928 --> 00:20:48,740 and I pay for wind power. 442 00:20:48,740 --> 00:20:53,160 But by my address, I think I know Google, at some point, 443 00:20:53,160 --> 00:20:55,510 it would tell you where your coal is coming from, right, 444 00:20:55,510 --> 00:20:58,130 based on your zip code or something like that? 445 00:21:01,900 --> 00:21:04,040 So there's a market in my neighborhood. 446 00:21:04,040 --> 00:21:05,044 I would have Pepco. 447 00:21:05,044 --> 00:21:06,650 It would probably be coal. 448 00:21:06,650 --> 00:21:08,856 But I've opted for wind power. 449 00:21:08,856 --> 00:21:11,600 I've had some people tell me that's not really 450 00:21:11,600 --> 00:21:13,742 doing anything. 451 00:21:13,742 --> 00:21:17,810 ORY ZIK: So obviously it does. 452 00:21:17,810 --> 00:21:20,510 Having wind is better than not having wind. 453 00:21:20,510 --> 00:21:22,340 The way it works today, since once 454 00:21:22,340 --> 00:21:23,990 you have an electron on the grid, 455 00:21:23,990 --> 00:21:27,080 it doesn't run with an ID card, you don't know. 456 00:21:27,080 --> 00:21:30,440 So people are loading wind electricity on their, 457 00:21:30,440 --> 00:21:34,040 let's say, New England IOS, and then it's assumed to be shared. 458 00:21:34,040 --> 00:21:37,460 I think we can do a better job with science 459 00:21:37,460 --> 00:21:41,310 for you to allow you to know your actual carbon footprint. 460 00:21:41,310 --> 00:21:43,910 So you can have a budget that actually 461 00:21:43,910 --> 00:21:46,700 relates to your activity. 462 00:21:46,700 --> 00:21:50,480 And I think that those numbers will create extra motivation. 463 00:21:50,480 --> 00:21:52,580 But obviously, your solar panels and the wind 464 00:21:52,580 --> 00:21:55,460 is a contribution, especially if the benchmark is coal. 465 00:21:55,460 --> 00:21:59,240 I mean, there's no argument about that. 466 00:21:59,240 --> 00:22:02,220 It's almost like the lemon problems in economics, 467 00:22:02,220 --> 00:22:08,290 that more transparency provides better value.
