Sustainability, the triple bottom line of economic profitability, respect for the environment and social responsibility: these are the new buzzwords of many a corporate annual report. Global companies everywhere are falling over themselves to declare their adherence to the principles of sustainable development. Is this a new moral crusade on the part of big business, or simply the result of pressure from demonstrators like those in Seattle and Genoa?
As the ocean covers three quarters of the surface of the earth, little wonder people see it as a possible source of freshwater. That basically means desalinating it to make it at least clean enough for agriculture and even good enough to drink. How does it work? Distillation is the cheap option, responsible for most desalinised water, but a newer filtering process using membranes, called reverse osmosis, now accounts for nearly half the world’s capacity to turn ocean into freshwater.
Every Thursday at noon the Tribunal de las aguas (water court) meets outside the cathedral in the city of Valencia along Spain’s Mediterranean coast. For more than a thousand years, it is believed, the court has ruled on disputes affecting the irrigation of the arable lands known as huertas, which nourish the lemon trees, the oranges and other crops that give this region its distinctive scents and flavours, and for many, livelihoods as well.
Achieving the Millennium Development Goal on water should not only require extension of access, but proper maintenance of existing infrastructure, too. It is a long-term challenge.
In the current financial crisis, risk-weary investors worry more about keeping their own boats afloat than in pumping money into a sector noted for high upfront costs, long pay back periods and low rates of return. Add to that an inefficient use of resources, weak regulation and lack of up-to-date information, and the water sector faces what may prove to be a dry season for investment.
The private water sector is larger than many people think, with thousands of businesses working every day, for the most part, to implement government policies. Are those businesses doing enough and how might they do more?
Pressures on the earth’s resources are building, but is the current economic model reaching breaking point? What can be done?
Transition to new energy sources is unavoidable, but here are five sobering first principles to remember along the way.
Global electricity demand declined in 2009 for the first time since the end of World War II according to OECD estimates. Electricity demand experienced a constant climb over the second half of the 20th century through the oil crises of the 1970s, the Black Monday crash of 1987, and on through the dot-com bubble bursting at the turn of the millennium as development countered all downward forces. The credit crunch of 2008 though, has resulted in a drop of as much as 1.6% based on OECD figures derived from the IMF’s latest GDP growth forecast for 2009.
Energy planning is not easy, and when governments shop around for energy sources, they must balance costs and benefits of available options.
Nuclear energy could help in the battle to reduce greenhouse gas emissions, but for many the production of nuclear waste outweighs this advantage. One important challenge is to convince an often reluctant public that with new waste disposal techniques, nuclear energy is worth a second look in the interests of sustainable development.
Fighting global warming means reducing dependency on oil. But though supply is insecure, it remains plentiful. Keeping oil in the energy mix makes sense.
Energy production and consumption patterns are shifting. So are the challenges for investment and global energy policy.
OECD countries share the same goals of sustainable development, but differ in their views on the role of nuclear energy in achieving those goals. Indeed, few energy sources have been scrutinised in the public spotlight over the years quite as much. The question is simple: is nuclear really a sustainable energy?
While bemoaning the global impact of rich countries’ subsidies on poorer economies, environmentalists are taking a closer look at how the elimination of some subsidies may be detrimental to the environment.
Can biofuels truly compete with petrol? Recent projections suggest that ethanol could represent up to 5% of the world’s transport fuel by 2010. That figure may seem modest at first glance, but it is significant, considering no other alternative fuel has had an equivalent impact on the gasoline market in over 100 years.
Can anything be done to tackle transport problems and steer them to a more manageable level? There has been no shortage of trying.
Global warming, finite fossil fuels and geopolitical risks make a shift to renewable energies inevitable. Though it is a challenge fraught with uncertainties, no action would be worse. An alternative, workable energy strategy is within reach.
Can taxation help governments achieve environmental goals with respect to energy use and emissions? Yes, with conditions.
By 2020 transport will account for more than half the world’s oil demand, and will generate nearly a quarter of the world’s energy-related CO2 emissions. According to projections in this book from the International Energy Agency, a sister organisation of the OECD, the rate of increase in transportation oil use is expected to be three times higher in developing countries than in the OECD, though the latter will still account for the lion’s share of emissions.
The possibility of using renewable energy to produce electricity on a significant scale is a heated debate.
As biofuel production grew fourfold from 2000 to 2008, criticism of the industry seemed to increase nearly as dramatically. Production of these transport fuels, which are based on food crops such as grains, sugar cane and vegetable oils, competes with food crops and drives up food prices, experts argue. Also, from land-clearance needed for cultivation, production and use, these biofuels may actually increase, rather than reduce, greenhouse gas emissions.
Once hailed as the imminent successor to fossil fuels, biofuels are hitting some rough patches. Is it time to apply the brakes?
Energy has moved to the top of our policy agendas, and with good reason. First, there is the price of oil, which though easing a little in recent months, remains historically high. This has pushed up costs for producers and consumers alike.
Water holds huge potential for economic, social and individual betterment. There are challenges to confront, but also opportunities. With the right approach, water could be a harbinger of progress.
