对话 Mathis Wackernagel:如何才能让不同的受众更清楚地理解资源安全的重要性

By | 未分类 | No Comments

Why did you write “Ecological Footprint: Managing Our Biocapacity Budget” now?

Bill Rees and I wrote our first Ecological Footprint book in 1995 at a time when our resource-use estimates were still crude. The book summarized my Ph. D. dissertation, including a presentation of the basic premises of the idea as well as some basic applications. After this first book, I shifted strategy. I started to disseminate Ecological Footprint thinking through other organizations, including WWF, international agencies and national governments, to give it wider visibility and accelerate its mainstream adoption. Now, 25 years later, the time has come to provide an updated introduction to the whole approach. With a clear goal in mind: How to make Ecological Footprint accounting accessible, relevant, and fresh.

What are the main findings since you published the first Ecological Footprint book 25 years ago?

In 1995 we only had a rough estimate for Canada and an overly crude one for humanity. By 1997 we started to do more systematic national calculations. Global Footprint Network started in 2003 with annual updates for (nearly) every country on the planet and time series all the way back to 1961. Those accounts kept getting more and more refined. They are now so refined, as a matter of fact, that we gave them their own independent organization: www.FoDaFo.org. Back in 1995, I was expecting a faster evolution of the sustainability debate than we actually witnessed over the past 25 years. Furthermore, unsustainable trends have continued nearly unabated – from using 1.3 Earths in 1995 to using 1.75 Earths now. Most policy makers still miss or choose to ignore the fact that without resource security, humanity – and every country with it – is putting its own ability to operate at risk. And I am perpetually stunned to observe how hard it is to make this unavoidable reality obvious to wider audiences. So this has been a challenge we set ourselves: how can we make the need for resource security more obvious to diverse publics?

Can you share with us the key 3 take-away messages in this book?

  1. Biocapacity is the ultimate currency. Earth’s renewal capacity is the most limiting of all material resources. That is why mapping all our demands against biocapacity not only makes sense but is imperative. Embracing this biological perspective allows us to clearly distinguish which strategies may be successful and which ones are doomed to fail.
  2. We live in unusual times. Our enormous dependence on fossil fuel seems normal to most of us. After all, “hasn’t it always been this way?” In reality, it is highly abnormal. Of all the fossil fuel ever burnt in the entire human history, 80% was burnt during my short lifetime. The book tells you how much was burnt during yours. It was 46% since Justin Bieber was born.
  3. It is the economy, stupid. That was Clinton’s presidential stump-speech. And he might be right on the money. In fact, we’ve been striving to make the case that embracing sustainability is economically superior and advantageous for humanity at large, starting with those who put their decision-making through a sustainability lens. Without this lens, we put our businesses, our cities, our countries even, into ever more inescapable traps.

What did you learn writing the book?

There is so much we want to tell, but ultimately including too much may not be helpful. It is more important to make the stories digestible. Bert and I challenged ourselves to translate complex ideas into examples that anybody could relate to. And to make sure the book is not just filled with theoretical ideas, but practical examples and applications. Also, when working on the acknowledgments, I started to realize how many people have contributed to this work. That is rather humbling. And I am particularly embarrassed about all the people I forgot to mention.

How confident are you that humanity’s Ecological Footprint can be brought in balance with Earth’s capacity to renew biological resources?

In this instance, I try to avoid thinking about probability – rather I focus on possibility. Is it possible to get out of ecological overshoot by design and not by disaster? The answer is a resounding yes. It is possible if enough people want to. It seems to me, however, that too few of us are convinced that we have personal “skin in the game” – that this context truly matters to our own lives. Fortunately, those high-schoolers boycotting school on Fridays around the world show us the way: they know that climate action is essential for their own ability to choose the life they want to live. They accuse the older generation for having failed them for a reason: too many decision makers – national and regional policy, large scale investments, urban planning – believe indeed that sustainability is merely a noble cause, not a necessary condition for prosperity. I’m afraid they are betting on the wrong horse. I predict that their blindness is undercutting their own chances at being successful. This book explains why.

中国是否能实现生态文明转型?

By | Guizhou Initiative, 未分类 | No Comments

构建与自然和谐共处的经济发展模式是习近平主席关于国家向生态文明转型美好愿景的重要体现。

中国是否可以实现这样的文明?

为了寻求答案,我们与贵州省达成了合作关系。我们于7月6日在贵阳举办的“生态文明贵阳国际论坛2016年年会”中发布了合作的重要成果《贵州生态足迹报告:生态文明量化标准》。

毋庸置疑的是,中国正面临着极大的挑战:迅速增长的资源需求已经超过其可以提供的生态资源和服务;对石油燃料的严重依赖;人们对经济发展的期望,尤其是欠发展地区人民渴望脱离经济发展的困境。

贵州足迹报告受到瑞士政府的鼎力支持。作为中国独特拥有山地生态系统,丰富生物多样性和多民族群体的地区,贵州和瑞士却有着相似的地理环境。报告中分析对比了两个国家的情况。

接下来是我们关于贵州面临挑战的重要发现:

  • 贵州人均年收入为18700元(约2852美元),人均生态足迹为72gha与中国其他省区相比,贵州的人均收入排名倒数第五,人均生态足迹排名倒数第六。中国人均生态足迹为3.4gha而瑞士的为5.8gha。而报告的最终研究表明,贵州人均生态足迹已经达到1.98gha。
  • 在贵州,生态足迹的51%来自政府和民间对耐用资产的投资, 其余 49% 则来自于家庭日常消费, 包括食品, 住房, 交通, 商品和服务。在中国,47% 的足迹来自私人和政府投资,而53% 来自家庭消费。相反,在瑞士,29% 的足迹来自私人和政府投资,而71% 来自家庭消费。
  • 根据联合国的人类发展指数计算,测量人类幸福,贵州为62。低于0.7的高发展水平也低于中国平均值0.73。

我们与贵州合作的成果基于世界自然基金会中国(WWF China)与全球足迹网络合作的《中国生态足迹报告》。我们共同热切盼望中国更多省份加入我们。我们下一站将前往四川省。

全球足迹网络和中国科学院(IGSNRR)有着密切合作关系。中国专家学者已经在国际学科刊物上发表许多有关生态足迹的论文。全球足迹网络希望加速促成中国学术在生态足迹核算方面的领导地位。

世界粮食价格波动将对中国和印度GDP造成最大影响

By | Ecological Limits, 未分类 | No Comments

Report published by UNEP and Global Footprint Network ranks countries on the economic risks they face from a hike in food prices

(London 18 May 2016) – If global food prices double then China could lose $161 billion in GDP and India could lose $49 billion, according to a new report released today by the United Nations Environment Programme (UNEP) and Global Footprint Network.

The UNEP-Global Footprint Network report, entitled ERISC Phase II: How food prices link environmental constraints to sovereign credit risk, features a table that ranks countries according to how badly they will be affected if global food commodity prices double.

In the future, the world will likely suffer from higher and more volatile food prices as a result of a growing imbalance between the supply and demand of food, the report notes. Rising populations and incomes will intensify the demand for food while climate change and resource scarcity will disrupt food production.

The report, which was published in collaboration with Cambridge Econometrics and several leading financial institutions, models the impact of a global food price shock on 110 countries to assess which countries face the greatest economic risk from this growing imbalance.

In terms of the highest percentage loss to GDP, the five countries that will be worst hit if food commodity prices double are all in Africa – Benin, Nigeria, Cote d’Ivoire, Senegal and Ghana. But China will see the most amount of money wiped from its GDP of any country – $161 billion, equivalent to the total GDP of New Zealand. India will see the second highest loss to GDP – $49 billion, equivalent to the total GDP of Croatia.

Among the report’s other key findings are:

  • Overall, Egypt, Morocco and Philippines could suffer the most from a doubling of food prices in terms of the combined impact on GDP, current account balance and inflation.
  • 17 out of the 20 countries most at risk from a food price shock are in Africa.
  • Paraguay, Uruguay, Brazil, Australia, Canada and the US would benefit the most from a sharp increase in food commodity prices.
  • Globally, negative effects of a food price shock massively outweigh positive effects in absolute terms. While China could see an absolute reduction in GDP of $161 billion, the highest absolute positive effect on GDP, seen in the United States, is only $3 billion –50 times smaller than the impact on China.
  • In 23 countries, a doubling in food prices leads to a 10 per cent (or more) rise in the consumer price index.
  • Countries with higher sovereign credit ratings tend to be less exposed to risks resulting from a food price spike.
  • Countries whose populations have the highest consumption of natural resources and services, and are therefore most responsible for the environmental constraints that make future food prices higher and more volatile, tend to face the lowest risk exposure.

UNEP Executive Director Achim Steiner said, “Fluctuations in food prices are felt directly by consumers and reverberate throughout national economies. As environmental pressures mount, it is important to anticipate the economic impact of these stresses so that countries and investors can work on mitigating and minimizing risk. And as the global population continues to rise, food prices can be a bellwether for how environmental risk translates to economic risk and vulnerability.”

Susan Burns, co-founder of Global Footprint Network and director of its Finance Initiative, said: “Now more than ever, in this era of climate change, identifying all relevant environmental risks is crucial to investing not only in equities but also sovereign bonds.

“As this latest research shows, disruptions to our food system represent one substantial environmental risk that both investors and governments may be largely overlooking but would be well-served to integrate into their risk analysis.”

The ERISC Phase II report was published in collaboration with Cambridge Econometrics and several financial institutions: Caisse des Dépôts, First State Investments, HSBC, Kempen Capital Management, KfW, and S&P Global Ratings.

The report builds on the first Environment Risk Integration in Sovereign Credit (ERISC) report published in 2012 by UNEP FI and GFN.

The overall objective of the ERISC project is to assesses how environmental risks such as deforestation, climate change and water scarcity affect economies, given that GDP, inflation and current account balances underpin some of the criteria that determine a country’s sovereign credit rating and the cost of borrowing on international capital markets.

UNEP and GFN would like to invite interested parties, governments, banks, investors and rating agencies to work with them to further decipher the link between environmental constraints and sovereign credit risk.

Today’s ERISC report comes ahead of the release of a landmark report on food systems and natural resources written by the International Resource Panel (IRP), a consortium of 34 internationally renowned scientists, over 30 national governments and other groups hosted by UNEP.

The IRP report, which lists a series of solutions that will improve the world’s food system, will be released in Nairobi on 25 May at the United Nations Environment Assembly – the world’s de facto Parliament for the Environment.

人类对我们星球的需求已超过了自然可以再生能力的一半还多,这正在威胁人类的福祉和哺乳动物、鸟类、爬行动物及鱼类的数量。这是全球足迹网络、世界自然基金会和伦敦动物学会今天发布的数据。(足迹网络2015年9月29日于美国奥克兰)

Every two years, Global Footprint Network, WWF and the Zoological Society of London publish the Living Planet Report, the world’s leading, science-based analysis on the health of our planet and the impact of human activity. The Living Planet Report uses the Ecological Footprint and additional complementary measures to explore the changing state of global biodiversity and human consumption. The report documents the extent of human pressure on the planet, how that compares across nations, and how it is impacting the natural world.

Humanity’s Demand on Nature Climbs as Biodiversity Suffers Major Decline

Click to view full reportThe Living Planet Report 2014, released September 30, 2014, shows that humanity’s demand on the planet is more than 50 percent larger than what nature can renew, jeopardizing the well-being of humans as well as populations of mammals, birds, reptiles, amphibians and fish.

Humanity’s Ecological Footprint has more than doubled since 1961, according to the Living Planet Report. At the same time, vertebrate wildlife populations have declined, on average, by more than half in just four decades, as measured by the Living Planet Index.

It would take 1.5 Earths to produce the resources necessary to support humanity’s current Ecological Footprint. This global overshoot means, for example, that we are cutting timber more quickly than trees regrow and releasing CO2 faster than nature can sequester it.

Growth in the Ecological Footprint is largely attributable to the carbon Footprint, which has increased to comprise 53 percent of our Footprint in 2010 from 36 percent in 1961. Carbon emissions (in particular) and food demand are the major drivers of the escalating Footprint. In addition, from 1961 to 2010, the global human population increased from 3.1 billion to 6.9 billion, and the per capita Ecological Footprint increased from 2.5 to 2.6 global hectares.

科学研究表明更多投资需求以达到2020年生物多样性目标

By | 未分类 | No Comments

发表在《科学》、全球足迹网络研究人员作为作者之一的一项新的研究成果表明,尽管取得了一些进展,但要达到国际达成的2020年生物多样性的目标还需要做更多努力。(《科学》,2014年10月,奥克兰)

(OAKLAND, CA, USA) — OCTOBER 2, 2014 —A new study published in Science today and co-authored by Global Footprint Network’s researchers reveals that, despite some progress, more needs to be done to reach an internationally agreed set of biodiversity targets by 2020.

Ecosystems and the biodiversity that underpin them are vital for sustaining human life. Recognizing this, in 2010, 193 nations agreed on a set of 20 biodiversity-related goals, known as Aichi Biodiversity Targets.

At this mid-way point to the 2020 deadline, a team of 51 experts from over 30 institutions have assessed progress towards the Aichi Biodiversity Targets, and projected whether or not they will be met. They reveal that despite increasing management efforts and financial investment in protecting biodiversity, and a remarkable expansion in protected areas on land and at sea, accumulated and increasing pressures on the natural world mean it is unlikely that most of the targets will be met by 2020 if we remain on our current trajectory.

To assess progress towards the Aichi Biodiversity Targets, experts used a broad range of data on biodiversity and human indicators such as global bottom-trawl fishing pressure, efforts to manage invasive species, financial investment, and public understanding of biodiversity. They then projected these trends to assess the state of biodiversity in 2020.

“The Aichi Biodiversity Targets represent the most important international commitment towards preserving biodiversity,” says Derek Tittensor, Lead Author and Senior Marine Biodiversity Scientist at United Nations Environment Programme World Conservation Monitoring Centre and Adjunct Professor at Dalhousie University. “However, our projections show that the impact of current management and policy efforts is not enough to halt biodiversity declines and meet most of the targets by 2020.”

Global Footprint Network’s Ecological Footprint is one of the pressure indicators included in the analysis. “Over the past five decades, the biosphere’s ecosystems have been put under increasing pressure due to humanity’s growing demand for resources and ecological services,” says Alessandro Galli, a Global Footprint Network senior scientist and director of the organization’s Mediterranean-MENA Program.

“Although evidence exists that actions taken to protect biodiversity might have slowed the decline in biodiversity, the growing societal responses have not contributed to major reductions in human-induced pressures,” Galli adds. “Among various factors, this might be due to the fact that most of these responses have focused on addressing the state of biodiversity rather than the pressures upon it.”

As shown in the Science paper, increased pressures on biodiversity suggest that the situation is worsening. The consumption of natural resources is increasing. Decreasing wetland extent and declining coral cover reflect large-scale habitat loss. At current rates, Aichi Biodiversity Targets to halve the rate of natural habitat loss and sustainably harvest all fish stocks will not be achieved – but there remains sufficient time to change this outcome.

“The Aichi Biodiversity Targets are still within reach,” says Dr Braulio Ferreira de Souza Dias, Executive Secretary of the Secretariat of the Convention on Biological Diversity. “We have numerous examples of successful policy efforts to halt or slow biodiversity loss. This study acts as a wake-up call that these efforts should become more widespread.”

Substantial progress is being made on individual targets. Certification schemes for forests and fisheries are becoming more widespread. Policy interventions have resulted in reduced deforestation and led to better managed fisheries stocks in some regions. There is also growing public awareness of biodiversity. Financial resources are being made available to address the biodiversity crisis, but more investment is needed to fulfill all targets.

The results of this study feed into a global assessment of the status and trends of biodiversity – the fourth edition of the Global Biodiversity Outlook (GBO-4) – which is being released on 6 October during the upcoming meeting to the Conference of the Parties to the Convention on Biological Diversity in Pyeongchang, Republic of Korea. During this meeting the necessary actions and novel solutions required to meet the Aichi Biodiversity Targets and preserve biodiversity will be discussed.

About the Aichi Biodiversity Targets
The Aichi Biodiversity Targets for 2011-2020 were adopted at the Convention on Biological Diversity’s tenth meeting of the Conference of the Parties in October 2010 in Nagoya, Aichi Prefecture, Japan. They formed part of the revised and updated Strategic Plan for Biodiversity which provides an overarching framework on biodiversity for biodiversity-related conventions, the United Nations system, and all partners engaged in biodiversity management and policy development.

The mission of the plan is to “take effective and urgent action to halt the loss of biodiversity in order to ensure that by 2020 ecosystems are resilient and continue to provide essential services, thereby securing the planet’s variety of life, and contributing to human well-being, and poverty eradication. To ensure this, pressures on biodiversity are reduced, ecosystems are restored, biological resources are sustainably used and benefits arising out of utilization of genetic resources are shared in a fair and equitable manner; adequate financial resources are provided, capacities are enhanced, biodiversity issues and values mainstreamed, appropriate policies are effectively implemented, and decision-making is based on sound science and the precautionary approach.”

全球超载日:2015年8月13日

还不到八个月,人类就用完了今年全年的自然预算,其中碳封存占对自然需求的一半以上。(全球足迹网络2015年8月12日于美国奥克兰)

Carbon emissions continue pushing the Ecological Footprint further above the planet’s annual budget

(OAKLAND, CA, USA) — AUGUST 13, 2015 —In less than eight months, humanity has used up nature’s budget for the entire year, with carbon sequestration making up more than half of the demand on nature, according to data from Global Footprint Network, an international sustainability think tank with offices in North America, Europe and Asia.

Global Footprint Network tracks humanity’s demand on the planet (Ecological Footprint) against nature’s ability to provide for this demand (biocapacity). Earth Overshoot Day marks the date when humanity’s annual demand on nature exceeds what Earth can regenerate in that year. Earth Overshoot Day has moved from early October in 2000 to August 13th this year.

The costs of this ecological overspending are becoming more evident by the day, in the form of deforestation, drought, fresh-water scarcity, soil erosion, biodiversity loss and the buildup of carbon dioxide in the atmosphere. The latter will significantly amplify the former, if current climate models are correct. Consequently, government decision-makers who factor these growing constraints in their policy making will stand a significantly better chance to set their nation’s long-term economic performance on a favorable track.

“Humanity’s carbon footprint alone more than doubled since the early 1970s, when the world went into ecological overshoot. It remains the fastest growing component of the widening gap between the Ecological Footprint and the planet’s biocapacity,” said Mathis Wackernagel, president of Global Footprint Network and the co-creator of the Ecological Footprint resource accounting metric. “The global agreement to phase out fossil fuels that is being discussed around the world ahead of the Climate Summit in Paris would significantly help curb the Ecological Footprint’s consistent growth and eventually shrink the Footprint.”

The carbon footprint is inextricably linked to the other components of the Ecological Footprint — cropland, grazing land, forests and productive land built over with buildings and roads. All these demands compete for space. As more is being demanded for food and timber products, fewer productive areas are available to absorb carbon from fossil fuel. This means carbon emissions accumulate in the atmosphere rather than being fully absorbed.

A Second Chance

The climate agreement expected at the United Nations Conference of Parties (COP) 21 this December will focus on maintaining global warming within the 2-degrees-Celsius range over pre-Industrial Revolution levels. This shared goal will require nations to implement policies to completely phase out fossil fuels by 2070, per the recommendations of the Intergovernmental Panel on Climate Change (IPCC), directly impacting the Ecological Footprints of nations.

Assuming global carbon emissions are reduced by at least 30 percent below today’s levels by 2030, in keeping with the IPCC’s suggested scenario, Earth Overshoot Day could be moved back on the calendar to September 16, 2030 (assuming the rest of the Footprint would continue to expand at the current rate), according to Global Footprint Network.

This is not impossible. In fact, Denmark has cut its emissions over the last two decades at this rate: Since the 1990s, it reduced its carbon emissions by 33 percent. Had the world done the same (while not changing the rest of the Footprint), Earth Overshoot Day would be on October 3 this year.

This is not to say that Denmark has already reached a sustainable Ecological Footprint.  Humanity would require the resources of 2.85 planets if everyone lived like the Danes, which would move Earth Overshoot Day to May 8.

Business As Usual

By contrast, business as usual would mean using the resources equivalent to two planets by 2030, with Earth Overshoot Day moving up on the calendar to the end of June.

This projection assumes that biocapacity, population growth and consumption trends remain on their current trajectories. However, it is not clear whether a sustained level of overuse is possible without significantly damaging long-term biocapacity, with consequent impacts on consumption and population growth.

Tipping Point

“We are encouraged by the recent developments on the front line of renewable energy, which have been accelerating worldwide, and by the increasing awareness of the finance industry that a low-carbon economy is the way of the future,” said Wackernagel. “Going forward, we cannot stress enough the vital importance of reducing the carbon footprint, as nations are slated to commit to in Paris. It is not just good for the world, but increasingly becoming an economic necessity for each nation. We all know that the climate depends on it, but that is not the full story: Sustainability requires that everyone live well, within the means of one planet. This can only be achieved by keeping our Ecological Footprint within our planet’s resource budget.”

只有8个国家满足联合国采纳的可持续发展目标中的两个关键条件

目前世界有八个国家达到了全球可持续发展的两项主要最低条件,即联合国量化的国民满意生计指标和生态足迹量化的符合星球资源预算约束的生存指标。(全球足迹网络2015年9月23日于美国奥克兰)

OAKLAND, SEPTEMBER 23, 2015—Eight countries in the world currently meet two key minimum conditions for global sustainable development: satisfactory well-being for their residents, as measured by the U.N., and living within the planet’s resource budget, according to Global Footprint Network, an international sustainability think tank with offices in North America, Europe and Asia. Global Footprint Network monitors this second condition by tracking humanity’s demand on the planet (Ecological Footprint) against nature’s ability to provide for this demand (biocapacity).

The findings come as 193 nations are meeting this week in New York to adopt Sustainable Development Goals (SDGs) to secure well-being for all on this one planet, regardless of income level, gender or ethnicity.

Mapping the sustainable development of nations

“Caring for the Earth,” the seminal 1991 report jointly issued by the International Union for the Conservation of Nature (IUCN), the U.N. Development Programme and WWF, provided the most specific definition of sustainable development: “improving the quality of human life while living within the carrying capacity of supporting eco-systems.”

“Fulfilling this universal dream requires progress without any additional costs for future generations. This means it will be crucial to manage natural resources carefully so that we live within the means of nature,” said Mathis Wackernagel, president of Global Footprint Network.

The concept of “well-being for all” has its own U.N.-developed metric: the Human Development Index. HDI is based on the life expectancy, education and income of a nation’s residents. On a scale of zero to one, the U.N. Development Programme defines 0.7 as the threshold for a high level of development (0.8 for very high development.)

The concept “within the means of nature” is measured by the Ecological Footprint. The Footprint adds up the competing demands on productive surfaces, including food, fiber, timber, carbon dioxide sequestration and space for infrastructure.

At current population levels, our planet provides only 1.7 global hectares (gha) of biologically productive surface area per person. Thus, the average Ecological Footprint per person worldwide needs to fall significantly below this threshold if we want to accommodate larger human populations and also provide space for wild species to thrive.

Each nation’s endowment and ability to trade vary enormously. However, to achieve global sustainable development, with an HDI of at least 0.7, humanity’s demand on nature has to fall below an average of 1.7 gha per person, based on current population levels.

While the HDI of most nations has been steadily increasing over the past decades, their Ecological Footprint has been growing as well. Humanity’s annual demand on nature currently exceeds what Earth can regenerate in that year by 60 percent.

Algeria, Colombia, Cuba, Ecuador, Georgia, Jamaica, Jordan and Sri Lanka are the only countries that currently meet the two minimum criteria for global sustainable development. They enjoy “high human development” (even “very high human development” in the case of Cuba) while keeping their Ecological Footprint lower than 1.7 global hectares per person, according to Global Footprint Network and United Nations data.

By contrast, both the United States and China meet the minimum HDI requirement, while missing the second criteria by exceeding the 1.7 gha per person Ecological Footprint level. In India, meanwhile, the Ecological Footprint per person is 0.9 gha, substantially lower than the 1.7 gha per person global threshold, and its HDI is only 0.58. (See sortable HDI-Footprint Chart for more than 150 countries.)

Resource risk is acute for 71 percent of the global population

However, growing population and increasing consumption continue adding pressure on ecological constraints and contributing to climate change, compounding resource risks for every country’s economy. Such risks are most evident in countries whose Ecological Footprints are larger than what their ecosystems can renew—these countries are running “ecological deficits”—and who have low incomes, and therefore can less easily afford to buy their way out of resource scarcity.

A staggering 71 percent of the world population now lives in countries with this double-challenge: ecological deficits AND lower-than-world-average income. That’s up from less than 15 percent in the early 1960s.

“Putting natural resource security squarely into the development equation will be essential to ensuring that sustainable development is achieved,” said Wackernagel. “We hope the Sustainable Development Goals will spur all of us to move forward along this path.”
