what could be the potential solutions to climate change
Currently, family-planning programs receive just one percent of all overseas development assistance. These landscapes have the potential to capture and store vast amounts of carbon – thus helping reduce the harmful impacts of climate change. These impacts are expected to intensify in the coming decades. Wind energy is part of a system. And this one: The food we waste contributes 4.4 gigatons of CO2-equivalent into the atmosphere each year—roughly eight percent of total anthropogenic greenhouse-gas emissions. Nor is it about agencies or activists in rich countries, where emissions are highest, telling people elsewhere to stop having children. ... why we need to act promptly to mitigate its effects, and how each of us can contribute to a solution. Cost (Plausible Scenario): $41.6 billion net cost. Those outside experts would include students or just about anybody who is interested in contributing to climate change solutions, Kimbrough said. The fundamental need is for a “normative change” where society as a whole makes it abundantly clear that climate change is unacceptable, according to Coglianese. Climate change in Africa is an increasingly serious threat for Africans as Africa is among the most vulnerable continents to climate change. Sitemap. Below are the top ten solutions, ranked in terms of emissions reduction potential over a 30-year period. and Carbon Farming: These campaigns aim to promote regenerative agriculture—through encouraging farmers to practice it, retailers to sell products farmed in this manner, and consumers to look for products grown through regenerative methods. GHG reduction (Plausible Scenario): 59.6 GT of reduced CO2 by 2050. GHG reduction (Drawdown Scenario—requires providing more women with family-planning access): 59.6 GT of reduced CO2 by 2050. 2) Help girls overcome health barriers. Savings (Plausible Scenario): $5.02 trillion in net savings. Currently, “sell by” or “best before” dates and the like are largely unregulated designations, indicating when food should taste best. The problem: A third of the food raised or prepared does not make it from farm or factory to fork. But the data had some surprises in store. Campaign urges supermarkets to curb their extremely harmful HFC use, starting with the biggest offender: Walmart. Trees may be clustered, evenly spaced, or used as living fencing. In higher-income regions, major interventions are needed at the retail and consumer levels. Coglianese noted that the number of actors responsible for climate change “vastly exceeds” that of any other environmental problem. Kimbrough said a carbon tax is just one side of a coin. The Wharton School, University of Pennsylvania, 16 September, 2019. Scientists map soils’ potential to combat climate change ... which means that making strategic changes to how soil systems are used could play a major role in combating climate change. Roof modules are spreading around the world because of their affordability. He noted that these views reflect those of the wider Penn faculty, whom he represents this year as the Faculty Senate chair. Unabated climate change could one day look like bikinis outpacing parkas at booming tiki bars surrounding the world’s former glaciers. That situation provides “enormous opportunities for Wharton students, and for engineering students, to start thinking about ways of innovating in transportation,” such as with road structures, autonomous vehicles, electric vehicles and so forth, he said. GHG reduction (Drawdown Scenario—requires higher rate of adoption): 47.5 GT of reduced CO2-e by 2050.. For the other 90 solutions, we highly recommend you read Drawdown: the Most Comprehensive Plan Ever Proposed to Reverse Global Warming (Penguin Books, 2017), edited by Paul Hawken. Radical change from one state, or even the whole United States, won’t address climate change on its own, but taking these actions could help start the planet down a … In simpler words, climate change is the change in weather patterns which can last for extended period of time, even millions of years. Solutions in progress: Restoration of tropical forests, both passive and intentional, is now a growing trend. Cost (Plausible Scenario): Too variable to be determined. GHG reduction (Drawdown Scenario—requires more restoration): 89 GT of reduced CO2 by 2050.. Savings (Plausible Scenario): Data too variable to be determined. Many nations have put laws into place to fight climate change -- here’s what you can do. “There’s just so much that needs to be done and so many challenges with doing it,” she added. Climate change is fueling wildfires. Business-as-usual emissions could be reduced by as much as 70 percent through adopting a vegan diet and 63 percent for a vegetarian diet (which includes cheese, milk, and eggs). Eating too much of it can lead to certain cancers, strokes, and heart disease. It … The International Monetary Fund estimates that the fossil-fuel industry received more than $5.3 trillion worldwide in direct and indirect subsidies in 2015. Cost (Plausible Scenario): Data too variable to be determined. This is based on the United States. Growing the Green Economy for People and Planet, Adapted with permission from Drawdown: The Most Comprehensive Plan Ever Proposed to Reverse Global Warming (Penguin Books, 2017), edited by Paul Hawken, Top 10 Solutions to Reverse Climate Change. “We’re also putting it on our children.”. New research, led by The Nature Conservancy and 15 other institutions*, and published in the Proceedings of the National Academy of Sciences, demonstrates that nature-based solutions can provide up to 37 percent of the emission reductions needed by 2030 to keep global temperature increases under 2°C—30 percent more than previously estimated.. Loosely defined, climate is the average weather at a distinct place that incorporates temperature, precipitation, and … Cities around the world are the “main cause of climate change” but can also offer a part of the solution to reducing the harmful greenhouses gases that are causing global temperatures to rise according to UN-Habitat Executive Director Maimunah Mohd Sharif. Re(Store) It! Because the land is diversely productive, farmers are better insulated from financial risk due to weather events. Get Knowledge@Wharton delivered to your inbox every week. Cost (Plausible Scenario): By closing an annual financing gap of $39 billion, universal education in low- and lower-middle-income Three-quarters of that land would be best suited to a “mosaic” forest-restoration approach, blending forests, trees, and agricultural land uses. Natural climate solutions have the potential to reduce CO 2 emissions by an estimated 11.3 billion tons a year – equal to a complete halt in burning oil, according to our study. Work to be done: In 2011, the journal Science published a demographic analysis of the impact of girls’ education on population growth. The Wharton School is committed to sharing its intellectual capital through the school’s online business journal, Knowledge@Wharton. The weather is not the same everywhere. Tackling climate change calls for action on dozens, if not hundreds or thousands, of fronts, from developing new government policies, to planting trees and educating consumers. “Much of climate change is often sold as painful and difficult, and very unpleasant,” said Kimbrough. HFC substitutes are already on the market, including natural refrigerants such as propane and ammonia. Project Drawdown’s Plausible Scenario assumes restoration could occur on 435 million acres, resulting in: GHG reduction (Plausible Scenario): 61.2 GT of reduced CO2 by 2050. Kousky identified to-do plans for “three audiences” for the Penn report. Work to be done: “More than 4.9 billion acres [of forests] worldwide offer opportunities for restoration—an area larger than South America,” a team of researchers from the World Resources Institute reports. Cocoa Barometer 2020: No Meaningful Progress Made in 20 Years of Business Model That Ensures Poverty For Farmers, Trump Labor Department’s rule discouraging ESG investing in retirement plans is, Success! In places where income is low and infrastructure is weak, food loss is typically unintended and structural in nature—bad roads, lack of refrigeration or storage facilities, poor equipment or packaging, a challenging combination of heat and humidity. When placed on a grid-connected roof, they produce energy at the site of consumption, avoiding the inevitable losses of grid transmission. The connections between COVID-19 and climate change are real. Carbon reduction (Plausible Scenario): 24.6 GT of reduced CO2 by 2050. ️ Help us meet our Matching Gift Challenge! National goals and policies can encourage widespread change, as well. For the world, the decision is simple: Invest in the future or in the past. Some studies show that ruminants can better digest silvopastoral forage, emitting lower amounts of methane in the process. Their rates of maternal mortality drop, as do mortality rates of their babies. This solar panel replaced kerosene and provided electricity to the family for the first time. Making restoration a collaborative process can ensure it is done with and for local communities, and that root causes of forest damage are addressed. Above: Robin Rue Simmons at a press conference about equity in education in Evanston, Illinois. Polar ice shields are melting and the sea is rising. Courtesy of OCI Solar Power (OCISolarPower.com). In the poorest countries, per capita greenhouse-gas emissions are low. Between rapidly improving products, research at top universities, venture-capital investment, and mounting consumer interest, experts expect markets for non-meats to grow rapidly. “[However], climate risk solutions will demand those who are contributing to the problem to ‘internalize their externalities,’ [which means] they must start paying costs to reduce the spillover harms they impose on those who suffer the ravages of climate change.”, “The U.S. already has a climate tax,” noted Coglianese, who along with Penn Law fellow Mark Nevitt wrote an op-ed article in The Washington Post earlier this year on that subject. It is most essentially about freedom and opportunity for women and the recognition of basic human rights. Overconsumption of animal protein also comes at a steep cost to human health. Producing uneaten food squanders a whole host of resources—seeds, water, energy, land, fertilizer, hours of labor, financial capital—and generates greenhouse gases at every stage—including methane when organic matter lands in the global rubbish bin. Our new campaigns put pressure on AT&T, Verizon, and Amazon to power their massive servers with clean energy. From one-tenth of a ton of carbon dioxide per person in Madagascar to 1.8 tons in India, per-capita emissions in lower-income countries are a fraction of the US rate of 18 tons per person per year. The problem: Fossil fuels sidelined zero-emission wind energy during the mid-twentieth century. Another impediment to wind power is inequitable government subsidies. As mentioned, The decline in price has always outpaced predictions, and drops will continue. "Curbing Climate Change: 30 Solutions That Could Make an Impact." It will soon be much more. Carbon reduction (Drawdown Scenario—requires more solar rooftops): 43.10 GT of reduced CO2 by 2050. OCI Solar Power’s 60-acre Alamo 3 solar farm in Converse, TX, generates 5.5 megawatts (AC) of power for nearly 1,240 homes. Economic barriers include lack of family funds for school fees and uniforms, as well as prioritizing the more immediate benefits of having girls fetch water or firewood, or work a market stall or a plot of land. In regions of higher income, unintentional losses tend to be minimal; willful food waste dominates farther along the supply chain. Authoritative research indicates that Nature-Based Solutions can provide over one-third of the cost-effective climate mitigation needed between now and 2030 to stabilize warming to below 2 °C, achieving nature’s mitigation potential of 10-12 gigatons of CO2 per year. Coglianese pointed out that the transportation sector makes up about a quarter of greenhouse gas emissions in the U.S., including roads and materials used in them such as asphalt. Work to be done: The process of phasing out HFCs will unfold over many years, and they will persist in kitchens and condensing units in the meantime. The model also calculates a reduction in global mortality of six to ten percent. Saving tropical forests ranks #5 (see p. 23), and saving temperate forests ranks #12, with 22.61 GT of CO2-e. Fair Trade: Our Fair Trade program empowers women and girls by increasing family income, allowing girls to go to use. Ongoing cost reductions will soon make wind energy the least expensive source of installed electricity capacity, perhaps within a decade. Increased morbidity and health care costs go hand in hand. Most prominently was that even when the solutions are modeled in terms of what they call a “Plausible Scenario”—a conservative measure of projected solution implementation that is “reasonable yet optimistic”—society still makes great strides toward achieving drawdown, the point where greenhouse-gas levels in the atmosphere begin to decline. The historically large Camp Fire of 2018 caused at least ninety deaths, destroyed more than 18,000 structures, and covered an area roughly the same size as the Chicago metropolitan area. The IPCC made this forecast in 2007. Public investment, tax incentives, technology evolution, and brute manufacturing force have chipped away at the cost of creating PV, bringing it down to 65 cents per watt today. women (#62), composting (#60), saving water (#46), buying an electric car (#26), eating less meat (#4), reducing food waste (#3), and more. Using the scenario that gets us to drawdown—which requires ramping up the solutions a bit more than the conservative measure, particularly renewable energy—they reduce or sequester carbon by 1,442 gigatons by 2050. As a result, fertility rates halved in just one decade. GHG reduction (Drawdown Scenario—requires further reduction of meat consumption): 78.65 GT of reduced CO2-e by 2050. Investment in energy storage, transmission infrastructure, and distributed generation is essential to its growth. For example, offer child-care programs for mothers. 4) Make schools more girl-friendly. The World Economic Forum COVID Action Platform. Each year Schroders’ team of economists helps investors take a truly long-term view with 30-year return forecasts for a range of asset classes around the world. ... We mapped the global potential tree coverage to show that 4.4 billion hectares of canopy cover could … Solutions in progress: The United Nations’ Sustainable Development Goals call for halving per capita global food waste at the retail and consumer levels by 2030, as well as reducing food losses along production and supply chains. However, attempts to penalize emitters with a carbon tax have always faced political hurdles, said Coglianese. “What has to be done is convince people that it’s too expensive not to move forward. The encyclopedic book What Works in Girls’ Education (Brookings Institution Press, 2015) maps out seven areas of interconnected interventions: 1) Make school affordable. Cost (Plausible Scenario): –$80.6 billion. top 100 climate-change solutions. Electric vehicles, already increasingly common on the roadways, and rows of wind turbines generating clean energy are two of the more recognizable technological solutions for climate change… Tropical forest loss alone is responsible for 16 to 19 percent of greenhouse-gas emissions caused by human activity. The problem: Securing the fundamental right to voluntary, high-quality family-planning services, so women can have children by choice rather than chance and can plan their family size and spacing, is a matter of autonomy and dignity. The 2014 New York Declaration on Forests affirmed that aim and added a cumulative target of 865 million acres restored globally by 2030. The Knowledge@Wharton radio show on SiriusXM discussed some of the climate change solutions and major takeaways from the Penn report with Cary Coglianese, Penn law professor and political science professor and director of the Penn Program on Regulation; Steven O. Kimbrough, Wharton professor of operations, information and decisions, and Carolyn Kousky, executive director at the Wharton Risk Management and Decision Processes Center. Newer turbine designs address concerns over bird and bat deaths with slower-turning blades and siting practices to avoid migration paths. So-called geoengineering, radical interventions to either block sunlight or reduce greenhouse gases, is a potential last resort for addressing the challenge of climate change. The housing sector, land development patterns and living patterns are other areas where fresh solutions will be needed. The connections between COVID-19 and climate change are real. Savings (Plausible Scenario): $3.46 trillion net savings. Reducing greenhouse gas emissions is more important than reducing fossil fuel combustion, according to a paper in the Penn report by Mark Alan Hughes, professor of practice at Penn’s Weitzman School of Design and the founding faculty director of the Kleinman Center for Energy Policy. Nevertheless, changes in fertility rates in those countries would have multiple benefits for girls and women, families, communities, and society. In that effort, Hughes emphasized the importance of “negative emissions” technologies that help in carbon capture and removal. Transition: How do we minimize the transition risks for businesses and communities as we shift to a carbon-free economy in the face of uncertainty. Global energy consumption is increasing and we will face a shortage of fossil fuels in the coming decades. It details a “fast track” scenario, based on South Korea’s actual climb from one of the least to one of the most educated countries in the world. 04. Though not focused on safety, these markers often confuse consumers about expiration. top 100 climate-change solutions. And we could ask if having children is necessarily a bad thing for solving climate change: our challenges may mean we will need more problem-solvers in future generations, not fewer. Family planning requires social reinforcement—for example, the radio and television soap operas now used in many places to shift perceptions of what is “normal” or “right.”. “You can do that by making the fossil fuels more expensive and/or the replacements cheaper. Drawdown ranks 100 areas of climate change action according to their potential to avoid emissions between today and 2050, as well as associated costs and savings. Solutions in progress: The success stories in family planning are striking. Wastage occurs earlier in the supply chain, rotting on farms or spoiling during storage or distribution. (See #6 for statistics on per capita emissions.) These systems are more expensive to establish, requiring higher up-front costs in addition to the necessary technical expertise. Savings (Plausible Scenario): $699.4 billion net savings. Silvopasture can also cut farmers’ costs by reducing the need for feed, fertilizer, and herbicides. And climate change exacerbates other threats like habitat destruction, overexploitation of wildlife, and disease. In that paper, Orts makes a case for businesses to “get political” about climate change and “come together to counter the influence of reactionary business forces.”. It’s a tax that people are incurring already. What will it take to cut global climate pollution, despite an administration in Washington determined to ignore this dangerous threat? The solutions are ranked by the amount of greenhouse gases they reduce by 2050. He also pointed to an article by Nevitt, which advocates for a fresh look at regulatory restrictions that hamper climate control efforts. They are win-win solutions that involve protecting, restoring and sustainably managing ecosystems to address society's challenges and … Work to be done: Though the advantages of silvopasture are clear, its growth has been limited by both practical and cultural factors. Innovation around the pathways to a carbon-free world would also help. If a crop is unprofitable to harvest, it will be left in the field. Cattle and other ruminants require 30 to 45 percent of the world’s arable land, and livestock produce roughly one-fifth of greenhouse gas emissions. With that in mind, two Cornell soil scientists have helped develop a powerful new tool that will help researchers and policymakers map the global potential for carbon sequestration.
