Delegates from around the world are meeting in Rio de Janeiro to discuss how to make the planet more sustainable, despite a rapidly growing population. The reprise of the 1992 Rio Earth Summit dubbed "Rio+20" has so far drawn mixed reactions: some call it an "opportunity"; others say it is another step on a long, complicated road to realizing a more sustainable society. William K. Reilly, former U.S. Environmental Protection Agency (EPA) Administrator and chairman of the Nicholas Institute for Environmental Policy Solutions Board of Advisors chose to reflect on then and now, noting the two decades since leaders first met in Rio the "concept of sustainable development has evolved from theory to increasingly common practice." BBC News illustrates just how much the world has changed since the first Earth Summit.
Late Monday night, negotiators did agree on a draft framework for sustainable development goals. The text is not expected to change much when heads of state convene to discuss it, according to U.S. Special Envoy for Climate Change Todd Stern.
As the Washington Post reported, many of the concrete steps needed to move toward a more sustainable future are already being take on by major cities regardless of the outcome at Rio+20. The efforts of these 58 cities will cut greenhouse gas emissions by 248 million tons in 2020. U.N. Secretary General Ban Ki-moon hopes energy has a big role and introduced the "Sustainable Energy for All Plan" in Rio, which would end energy poverty by 2030.
Japan Sets Sights on Solar Future
As it shifts from nuclear power following the Fukushima radiation disaster, Japan is positioning itself to become the second largest market for solar power. The country introduced incentives for renewable energy that could expand revenue in this area to more than $30 billion by 2016. In the U.K., energy from renewable sources accounted for roughly 12.4 percent of the European Union's overall consumption, with Estonia recording the largest increase between 2006 and 2010.
Germany, who also opted to move away from nuclear by 2022, is feeling the burden of its decision. Miranda Schreurs, director of the Environmental Policy Research Center at Berlin Free University, said, "The way for Germany to compete in the long run is to become the most energy-efficient and resource-efficient market, and to expand on an export market in the process." If Germany succeeds, Technology Review reported, it could provide a workable blueprint for other industrialized nations.
A new report by the National Renewable Energy Laboratory finds the prospects for renewable energy, at least in the U.S., to be promising -- concluding it could supply 80 percent of the country's electricity by 2050.
Moratorium Mulled after Defeat of NC Sea Level Rise Bill
The North Carolina House of Representatives this week rejected a Senate bill that would have prohibited policy makers from using projections of accelerated sea level rise for coastal development planning purposes. This may lead lawmakers to enact a moratorium on such predictions pending further study by the state, which could take years. NewScientist breaks down the evidence of sea level rise in the state.
The EPA has turned down a demand by U.S. environmental groups to issue new regulations on greenhouse gas emissions from aircraft, ships and off-road vehicles, saying it "does not have the resources to consider all possible sources of climate change in the near or medium term." Meanwhile, the Senate on Wednesday defeated a proposed measure that would have overturned EPA's Mercury and Air Toxics Standard, or MATS, a rule aimed at limiting emissions of mercury, arsenic and other toxic air pollutants from coal-fired power plants. It will be the first federal standard to regulate toxic emissions from these plants, and is projected to result in coincident greenhouse gas reductions. A recent poll suggests most Americans favor the rule -- provided that companies are given enough time to comply.
Public companies in the UK -- some 1,600 in all -- may soon have to divulge all details about the greenhouse gases they emit, according to the Guardian. More companies may face the requirement, beginning as early as April 2013, after the policy is reviewed in 2015.
