Bruxelas – A comissária europeia do clima, Connie Hedegaard, reafirmou esta quinta-feira o desejo da União Europeia de obrigar as companhias aéreas a pagar um imposto pelas emissões de poluentes sobre seu território, apesar da oposição do organismo especializado da ONU para a aviação civil.

Hedegaard se disse “decepcionada de que as discussões no âmbito da Organização da Aviação Civil Internacional (OACI) se refiram uma vez mais ao que os Estados devem fazer”.

A OACI, uma instituição das Nações Unidas criadas em 1944 para promover o desenvolvimento seguro e ordenado da aviação civil no mundo, adotou esta quarta-feira, em Montreal, uma resolução não vinculante na qual recomenda isentar as companhias estrangeiras do imposto sobre as emissões de CO2.

O texto foi apoiado por 26 dos 36 membros da OACI, entre eles Estados Unidos, China, Rússia, destacou na quinta-feira o secretário-geral da Associação de Companhias Aéreas Europeias (AEA), Ulrich Schulte-Strathaus.

“A OACI infelizmente perdeu mais uma vez a oportunidade de dizer ao mundo o que custa fazer para reduzir as emissões de CO2 da aviação e quando pensa fazê-lo”, criticou Connie Hedegaard.

“Esta decisão não afeta, em nenhum caso, a decisão da UE, nem seu compromisso de trabalhar com a OACI para buscar uma solução global ao problema proposto pelas emissões da aviação”, afirmou.

A União Europeia decidiu em 2008 obrigar todas as companhias aéras que entram ou saem da UE a comprar o equivalente a 15% de suas emissões de CO2 a partir de 1º de janeiro de 2012 para combater o aquecimento global.

The larger the gulf between rich and poor the harder it is to find solutions for problems such as climate change


Inequality is the real issue for the world’s growing population. (Photography: Bloomberg/Bloomberg via Getty Images)

Is no-win politics on the rise? Unemployed protesters campaigning against a failed financial system are thought feckless, but employed ones get condemned as part-time and fair-weather. Economic growth drives environmental destruction, but without it, we’re told the economy will fall apart. A rising global population is deemed a threat, but so is a falling national one. All brilliantly confusing.

Anyone pondering the right way ahead feels paralysed by choices and apparent contradictions, but only the status quo benefits if we get frozen in the headlights. Several half-relegated issues, such as the population debate, have ridden the issue of climate change back into the centre of public debate. Population, of course, is about much more than that.

Germany, for example, is paranoid about the economic implications of a shrinking, aging population, while anti-immigration activists in the UK fan a range of scares about our rising population. The fact that UK population size is now on an apparent trend to overtake Germany is meant to be hugely symbolic, exactly how, though, is less clear. The difference between Germany and the UK is largely explained by different migration patterns, immigration history and average age of population (we’re much younger in the UK meaning more women are still likely to have children: the median age of women differs by a significant five years between the two countries).

Immigration compensated for the UK’s declining domestic birthrate and has brought a wide range of economic benefits. Taxes paid by migrant workers, for example, outweigh their costs. And “regularising” undocumented migrants already resident and working in the country could bring a £3bn economic benefit, according to a study by the London School of Economics.

But what benefits the UK in terms of the thousands of trained health and education professionals who migrate here to staff our schools and hospitals, can be a damaging drain on the sending countries.

Globally, fertility rates have fallen at such a rate that it is hard to imagine any socially acceptable policy intervention making any significant impact. About half a century ago, the average woman had between five and six children; now she has 2.6. At the level of 2.1 populations stabilise, and below that begin to decline.

High birth rates are crucially a function of poverty, related to lack of basic education (particularly for girls); lack of access to reproductive health services; high infant/child mortality rates; and dependence on adult children for income (not least as migrants). Whatever undermines health and education services in poor countries with high birth rates – the economic policies of international financial institutions or the drain of skilled professionals to rich countries – exacerbates the problem. In a less unequal world, the pressure to migrate would be greatly reduced.

The current economic system against which the “occupation” protest across the industrialised world are directed, both creates and depends on unsustainable consumption, and has driven income and asset inequality within and between nations. Fred Pearce, author of Peoplequake, argues that an obsession with population distracts from the real issue, overconsumption among the rich.

He quotes Stephen Pacala, director of the Princeton Environment Institute, who calculated that the world’s richest half a billion people – about 7% of the global population – account for half of the world’s emissions. Whereas, the poorest half of the world’s population account for just 7% of emissions.

Inequality is at the heart of the problem, whether the split is between the 99% majority and the 1% minority in whose interests the financial system operates, or the 7% representing half the world’s emissions and the rest.

Contrastingly, a huge range of problems, including over-consumption, become easier to solve in societies that are more equal (inequality drives status competition which in turn fuels consumption). The evidence of the last three decades is that redistribution is far more effective at tackling poverty than waiting for trickle-down from increasingly unequal growth. When the New Economics Foundation modelled the impact on the UK economy of reducing consumption to meet our climate change targets, we found that moving to Danish levels of equality compensated for the impact on GDP.

Which brings us full cycle to the protests in favour of financial reform (employed or not). Andrew Haldane at the Bank of England estimates that the ratio of CEO pay at the biggest seven banks compared to the national median wage in the US was 100:1 in 1989 and rose to 500:1 in 2007.

Reversing such startling polarisation, with active economic policy designed to increase equality at the national and global level, might not solve everything, but if it helps tackle economic stability, population concerns and climate change, that would be a good start.

A racha no glaciar Pine Island. (Fotografia: NASA / DMS)

Já é uma linha de 30 quilómetros que pode ser vista do ar, e que está a cortar mais um pedaço de gelo do glaciar Pine Island, na região Oeste da Antárctida. O fenómeno foi registado pela IceBridge, um projecto da Agência Espacial Norte Americana (NASA), quando ficar formado pode ter mais de 800 quilómetros quadros, o equivalente à área da capital alemã.

A IceBridge analisa o estado e as dinâmicas dos gelos polares para ajudar a estimar com mais correcção o aumento dos níveis médios do oceano. A NASA utiliza um avião que voa por cima das vastas áreas geladas da Antárctida que tem aparelhos para medir as características dos glaciares e permite aos cientistas avaliarem as dinâmicas dos gelos.

A 14 de Outubro os cientistas descobriram a racha no meio do glaciar. Desde 2001 que o Pine Island não produzia um iceberg tão significativo. A região tem um ciclo de cerca de uma década na produção de grandes glaciares. Os cientistas calculam que o iceberg irá desprender-se do continente no final deste ano ou no início de 2012.

Para já a racha tem 30 quilómetros de comprimento e 60 metros de altura. Mas quando se desprender, a profundidade do iceberg pode chegar aos 500 metros e ter uma área equivalente a dez vezes o concelho de Lisboa.

São Paulo – Para a Volkswagen, a mobilidade urbana do futuro é minimalista, ágil e, principalmente, amiga do meio ambiente. Exemplo disso é o modelo conceito que a fabricante alemã levará ao Salão de Frankfurt este mês. Inspirado nos carros de corrida da Fórmula 1, o Nils une design arrojado e agilidade no deslocamento.

Com um único assento, o do motorista, vem com um motor elétrico de 20cv alimentado por baterias de íons de lítio que podem se recarregadas em uma tomada comum por duas horas. Por se limitar a apenas um ocupante, ele é mais leve – com chassis em alumínio, pesa apenas 460 kg – e também consome menos energia.

O protótipo acelera dos 0 aos 100 km/h em 11 segundos e alcança 130 km/h de velocidade máxima. A autonomia é estimada em 25km – suficiente para viagens curtas e rotineiras, como a de casa ao trabalho e vice-versa.

Construction has begun on the world’s largest solar bridge.

Due for completion in 2012, the bridge, which spans the Thames at Blackfriars Station in London, will feature more than 4,400 solar panels, generating an estimated 900,000kWh of power a year.

The station, which is currently undergoing a multi-million pound redevelopment, will be powered by the panels, which are being installed above the station platform and out across the existing Blackfriars Bridge, which was built in 1886.

According to the Solarcentury, the company behind the project, the energy generated will reduce annual CO2 emissions by around 500 tonnes.

A Solarcentury statement read: “Blackfriars Bridge is an ideal location for solar; a new, iconic large roof space, right in the heart of London.”

“Station buildings and bridges are fixed parts of our urban landscape and it is great to see that this one will be generating renewable energy every day into the future.”

Speaking to the Huffington Post UK, Derry Newman, Solarcentury’s chief executive, said: “Not since the 16th century when our bridges were lined with shops and homes have we considered using these fantastic spaces in a more productive way.

“Blackfriars roof will not only protect the bridge, trains and passengers but produce 50 per cent of the stations energy.

“This project is symbolic of a new energy era, and shows what can be achieved if we put our built environment to work with 21st century clean technology.”

Desenvolver um ‘Mercado Global de Carbono Azul’ como uma forma de criar ganhos econômicos diretos através da proteção de habitats, é uma das ações propostas por um grupo de cinco agências das Nações Unidas.

Analisando os atuais desafios para o gerenciamento costeiro e oceânico, as cinco agências – Comissão Oceanografica Intergovernamental, UNESCO, FAO, PNUD e Organização Marítima Internacional – apresentaram na terça-feira um plano que visa contextualizar as discussões para a Rio +20.

O objetivo de uma das ações propostas é que instrumentos políticos sejam construídos no âmbito das negociações climáticas internacionais para criação de mecanismos que permitam no futuro o uso de créditos de carbono para a captura e armazenamento do carbono por ecossistemas marinhos e costeiros.

Para desenvolver e implementar uma estratégia global para o ‘carbono azul’, o grupo defende que padrões sejam construídos visando o monitoramento e a certificação e que metas sejam assumidas para a proteção dos habitats.

Além disso, é necessário o desenvolvimento de metodologias para valoração econômica dos serviços ecossistêmicos das ‘florestas azuis’.

Mudanças climáticas, acidificação, poluição e superexploração fizeram dos oceanos um dos ecossistemas terrestres mais ameaçados, colocando em risco não apenas a vida no planeta, mas também as aspirações da para prosperidade e crescimento econômico da humanidade no contexto do desenvolvimento sustentável, disse o grupo enfatizando que apenas 1% é protegido.

Os oceanos, que cobrem 70% da superfície terrestre, absorvem cerca de 26% das emissões de dióxido de carbono, sendo o maior sumidouro do planeta para este gás do efeito estufa.

O grupo enfatiza que 60% dos principais ecossistemas marinhos já foram degradados ou estão sendo usados insustentavelmente, sendo que os manguezais já perderam entre 30% e 50% da sua cobertura original enquanto os recifes de coral perderam 20%, aumentando a vulnerabilidade de muitas áreas costeiras superpovoadas.

BEIJING — Membership in the upper ranks of the Chinese Communist Party has always had a few undeniable advantages. There are the state-supplied luxury sedans, special schools for the young ones and even organic produce grown on well-guarded, government-run farms. When they fall ill, senior leaders can check into 301 Military Hospital, long considered the capital’s premier medical institution.

But even in their most addled moments of envy, ordinary Beijingers could take some comfort in the knowledge that the soupy air they breathe on especially polluted days also finds its way into the lungs of the privileged and pampered.

Such assumptions, it seems, are not entirely accurate.

As it turns out, the homes and offices of many top leaders are filtered by high-end devices, at least according to a Chinese company, the Broad Group, which has been promoting its air-purifying machines in advertisements that highlight their ubiquity in places where many officials work and live.

The company’s vice president, Zhang Zhong, said there were more than 200 purifiers scattered throughout Great Hall of the People, the office of China’s president, Hu Jintao, and Zhongnanhai, the walled compound for senior leaders and their families. “Creating clean, healthy air for our national leaders is a blessing to the people,” boasts the company’s promotional material, which includes endorsements from a variety of government and corporate leaders, among them Long Yongtu, a top economic official who insists on bringing the device along for car rides and hotel stays. “Breathing clean air is a basic human need,” he says in a testimonial.

In some countries, the gushing endorsement of a well-placed official would be considered a public relations coup. But in China, where resentment of the high and mighty is on the rise, news of the company’s advertising campaign is stirring a maelstrom of criticism. “They don’t have to eat gutter oil or drink poisoned milk powder and now they’re protected from filthy air,” said one posting on Sina Weibo, the country’s most popular microblog service. “This shows their indifference to the lives of ordinary people.”

News that Chinese leaders are largely insulated from Beijing’s famously foul air comes at a time of unusually heavy pollution in the capital. In recent weeks, the capital has been continuously shrouded by a beige pall and readings from the United States Embassy’s rooftop air monitoring device have repeatedly registered unsafe levels of particulate matter.

But those very readings, posted hourly on Twitter or through an iPhone app, have prompted a public debate over whether the Chinese government is purposely obscuring the extent of the nation’s air pollution. Unlike the American Embassy readings, Chinese environmental officials do not publicly release data on the smallest particulates, those less than 2.5 micrometers, which scientists say are most harmful because they are able to penetrate the lungs so deeply. Instead, government data covers only pollutants larger than 10 micrometers — a category that includes sand blown in from the arid north and dust stirred up from construction sites.

Environmental officials prefer to focus on air quality improvements of recent years, largely achieved by replacing coal-fired stoves with electric heaters and closing heavy industry in and around the capital. Driving restrictions have slightly eased the environmental injury of the 700,000 new vehicles that last year joined the capital’s jammed roadways.

But when pressed, those same officials acknowledge that their pollution metrics willfully ignore the smaller particles, much of them generated by car and truck exhaust. In fact, the American Embassy’s monitor has become an unwelcome intrusion into China’s domestic affairs, according to a diplomatic cable released this year by WikiLeaks, which said a Foreign Ministry official had requested that the Americans stop publicizing the data.

The director of the Institute of Public and Environmental Affairs, a nonprofit organization in Beijing, said many government officials feared that publicly revealing such data could stymie development or dent the image of cities that had been trumpeting their environmental bona fides.

“I don’t agree with this philosophy,” said the director, Ma Jun. “The government’s more urgent priority should be to warn the public when the air quality is dangerous so people susceptible to poor air quality, like children or the elderly, can make decisions to protect their health.”

The government does appear to be moving in that direction. In September, the Ministry of Environmental Protection said it planned to amend the nation’s air quality standards to include the smallest particulates, although it has not released a timetable for adopting the new standards.

Officials in Beijing, however, are apparently not quite ready to embrace it. In response to criticism over the heavy smog of recent weeks, a spokesman for the city’s environmental protection bureau, Du Shaozhong, assured the public that they should feel secure in the government’s own readings, which termed the city’s air “slightly polluted” even as the embassy monitor found it so hazardous that it exceeded measurable levels. “China’s air quality should not be judged from data released by foreign embassies in Beijing,” he said.

According to the Broad Group’s Web site, it did not take much to convince the nation’s Communist Party leaders that they would do well to acquire the firm’s air purifiers, some of which cost $2,000. To make their case, company executives installed one in a meeting room used by members of the Politburo Standing Committee. The deal was apparently sealed a short while later, when technicians made a show of cleaning out the soot-laden filters. “After they saw the inklike dirty water, Broad air purifier became the national leaders’ appointed air purifier!” the Web site said.
