NEWS Pontifical Academy of Sciences: Declaration of Health
DECLARATION: OUR PLANET, OUR HEALTH, OUR RESPONSIBILITY
This declaration is based on the data and concepts presented at the workshop:
Some forms of pollution are part of people’s daily experience. Exposure to atmospheric pollutants produces a broad spectrum of health hazards, especially for the poor, and causes millions of premature deaths. People take sick, for example, from breathing high levels of smoke from fuels used in cooking or heating. There is also pollution that affects everyone, caused by transport, industrial fumes, substances which contribute to the acidification of soil and water, fertilizers, insecticides, fungicides, herbicides and agrotoxins in general. Technology, which, linked to business interests, is presented as the only way of solving these problems, in fact proves incapable of seeing the mysterious network of relations between things and so sometimes solves one problem only to create others.
O God of the poor,
Help us to rescue the abandoned and forgotten of this earth, So, precious in your eyes. Bring healing to our lives,
That we may protect the world and not prey on it,
That we may sow beauty, not pollution and destruction.
Pope Francis, Laudato si’
Statement of the Problem
With unchecked climate change and air pollution, the very fabric of life on Earth, including that of humans, is at grave risk. We propose scalable solutions to avoid such cat– astrophic changes. There is less than a decade to put these solutions in place to preserve our quality of life for genera– tions to come. The time to act is now.
We human beings are creating a new and dangerous phase of Earth’s history that has been termed the Anthro– pocene. The term refers to the immense e ects of human activity on all aspects of the Earth’s physical systems and on life on the planet. We are dangerously warming the planet, leaving behind the climate in which civilization developed. With accelerating climate change, we put ourselves at grave risk of massive crop failures, new and re-emerging infectious diseases, heat extremes, droughts, mega-storms, oods and sharply rising sea levels. The economic activities that contribute to global warming are also wreaking other profound damages, including air and water pollution, deforestation, and massive land degrada– tion, causing a rate of species extinction unprecedented for the past 65 million years, and a dire threat to human health through increases in heart disease, stroke, pulmo– nary disease, mental health, infections and cancer. Climate change threatens to exacerbate the current unprecedent– ed ow of displacement of people and add to human mis– ery by stoking violence and con ict.
The poorest of the planet, who are still relying on 19th century technologies to meet basic needs such as cooking and heating, are bearing a heavy brunt of the damages caused by the economic activities of the rich. The rich too are bearing heavy costs of increased ooding, mega-storms, heat extremes, droughts and major forest fres. Climate change and air pollution strike down the rich and poor alike.
- Burning of fossil fuels and solid biomass release haz– ardous chemicals to the air.
- Climate change caused by fossil fuels and other hu– man activities poses an existential threat to Homo sapiens and contribute to mass extinction of species. In addition, air pollution caused by the same activi– ties is a major cause of premature death globally.
Supporting data are summarized in the attached background section. Climate change and air pollution are closely interlinked because emissions of air pollutants and climate-altering greenhouse gases and other pollutants arise largely from humanity’s use of fossil fuels and bio– mass fuels, with additional contributions from agriculture and land-use change. This interlinkage multiplies the costs arising from our current dangerous trajectory, yet it can also amplify the benefits of a rapid transition to sustainable energy and land use. An integrated plan to drastically reduce climate change and air pollution is essential.
- Regions that have reduced air pollution have achieved marked improvements in human health as a result.
We have already emitted enough pollutants to warm the climate to dangerous levels (warming by 1.5°C or more). The warming as well as the droughts caused by climate change, combined with the unsustainable use of aquifers and surface water, pose grave threats to availability of fresh water and food security. By moving rapidly to a zero-car– bon energy system – replacing coal, oil and gas with wind, solar, geothermal and other zero-carbon energy sources, drastically reducing emissions of all other climate altering pollutants and by adopting sustainable land use practices, humanity can prevent catastrophic climate change, while cutting the huge disease burden caused by air pollution and climate change.
- We advocate a mitigation approach that factors in the low probability-high impact warming projections such as the one in twenty chances of a 6°C warming by 2100.
We declare that governments and other stakeholders should urgently undertake the scalable and practical solu– tions listed below:
1. Health must be central to policies that stabilize climate change below dangerous levels, drive ze– ro-carbon as well as zero-air pollution and prevent ecosystem disruptions.
2. All nations should implement with urgency the glob– al commitments made in Agenda 2030 (including the Sustainable Development Goals) and the Paris Climate Agreement.
3. Decarbonize the energy system as early as possible and no later than mid-century, shifting from coal, oil and gas to wind, solar, geothermal and other ze– ro-carbon energy sources;
4. The rich not only expeditiously shift to safe energy and land use practices, but also provide nancing to the poor for the costs of adapting to climate change;
5. Rapidly reduce hazardous air pollutants, including the short-lived climate pollutants methane, ozone, black carbon, and hydro uorocarbons;
6. End deforestation and degradation and restore de– graded lands to protect biodiversity, reduce carbon emissions and to absorb atmospheric carbon into natural sinks;
7. In order to accelerate decarbonization there should be e ective carbon pricing informed by estimates of the social cost of carbon, including the health ef– fects of air pollution;
8. Promote research and development of technologies to remove carbon dioxide directly from the atmos– phere for deployment if necessary;
9. Forge collaboration between health and climate scienc– es to create a powerful alliance for sustainability;
10. Promote behavioral changes bene cial for human health and protective of the environment such as increased consumption of plant-based diets;
11. Educate and empower the young to become the leaders of sustainable development;
12. Promote an alliance with society that brings togeth– er scientists, policy makers, healthcare providers, faith/spiritual leaders, communities and founda– tions to foster the societal transformation necessary to achieve our goals in the spirit of Pope Francis’s en– cyclical Laudato Si’.
To implement these 12 solutions, we call on health professionals to: engage, educate and advocate for cli– mate mitigation and undertake preventive public health actions vis-à-vis air pollution and climate change; inform the public of the high health risks of air pollution and cli– mate change. The health sector should assume its obliga– tion in shaping a healthy future. We call for a substantial improvement in energy e ciency; and electri cation of the global vehicle eet and all other downstream uses of fossil fuels. Ensure clean energy bene ts also protect so– ciety’s most vulnerable communities. There are numerous living laboratories including tens of cities, many universi– ties, Chile, California and Sweden, who have embarked on a pathway to cut both air pollution and climate change. These thriving models have already created 8 million jobs in a low carbon economy, enhanced the wellbeing of their citizens and shown that such measures can both sustain
economic growth and deliver tangible health bene ts for their citizens.
