Radical! It's the New Sensible

Yes, let's be radical. It’s the only sensible option. We cannot wait a hundred years to see if theories about climate change are correct. It'll be too late. When people buy insurance to protect themselves or their property, it’s not because they’re certain a disaster is coming. Uncertainty is bad enough.

Don't Excuse Brazil's Deforestation

The Brazilian government is wrong in its climate change diplomacy. It has been supporting the idea that developing countries have no obligation to put a cap on greenhouse gases emissions. China and India take the same position. Their point is that the gasses accumulated in the Earth’s atmosphere today were generated by industrialized countries since the first Industrial Revolution and, therefore, rich countries have to assume responsibility for them.

Olympic Spirit Needed for Air

China is not seriously concerned about the quality of air. If it were so, the country would take stronger measures to mitigate its emissions of greenhouse gases and other air pollutants; it would cooperate with the international community to face the problem and protect its population from the terrible effects of pollution. China’s air pollution levels are among the world’s highest. According to the Worldwatch Institute, 16 out of the world’s 20 most polluted cities are Chinese and the consequences of air pollution are causes of 400,000 premature deaths in the country.

China is more concerned about its image, than its air quality. It would like to seem to be cleaner when thousands of foreigners arrive there to participate in the Olympic Games. As usually in authoritarian regimes the tendency is to ban the reality far way from the foreigners’ eyes, to makeup reality. The government wants to avoid embarrassments during the games. China has a huge and fast growing pollution problem. It will not be solved by temporarily banning cars from Beijing during the Olympic Games.

In Brazil, we also have problems with the quality of air. In part, the means to cope with air pollution has been a biofuel program. Brazil had started biofuel production in the 1970’s when oil prices skyrocketed, enlarging the Brazilian external deficit. Today, the country is self-sufficient in oil supply, but the biofuel program has been increasing. Brazilian ethanol has a well-structured distribution chain. Consumers can find ethanol in every gas station. Vegetal fuel, with no emissions of carbonic and nitrogen gases represents 40% of domestic fuels consumption. Nowadays, Brazilian auto industry produces only hybrid cars, able to run 100% on ethanol or any mix of ethanol and gas. All gasoline used in the country has 25% of ethanol added to it.

However, it is not enough. Despite its achievements, Brazil has had many of the problems of air pollution in its six major metropolitan areas, especially in São Paulo. A recent survey made by an environmental website, O Eco, founded that 55% of the population complained about the quality of air and a third of respondents reported respiratory diseases attributed to air pollution.

Air pollution travels, and effects areas far from where the site of emissions. That is why pollution is a global problem. The Chinese government is strongly investing to make the Olympic Games a success, but its concern with the problem is limited only to the worries about the athletes’ performance and criticism from Olympic authorities.

The only way to be sincerely responsible about this problem is to adopt here, there and everywhere mandatory measures to mitigate the emissions of gases that are affecting both human’s health and the Earth’s future.

Emissions Don’t Equal Development

**Editor's Note: This piece was written in response to a question asking panelists to choose the best of six proposals on how to move forward on climate change. Read More Panelist Views**


The final accord in Bali saved countries from a different deadlock that would have been even harder to break. That was encouraging, because the alternative was a total breakdown of the negotiation process. We needed the roadmap to move ahead to a safer future. However, that doesn’t entice too much celebration. To keep the U.S. in the negotiations, it was necessary to reduce the emphasis and goals; to bring the emerging powers to the target system was necessary a diplomatic change of words. Instead of “mandatory targets” they will take “measurable, reportable and verifiable” measures. That’s something, but far less than what is necessary to reduce our risk.

Stop Wasting Corn on Ethanol

Let's start with good news. One part of the problem is that more people have gotten used to eating. The sustainable growth in many countries such as China, India, many African countries and throughout Latin America has increased income levels. This has delivered food security to millions of human beings who have never had it -- and, of course, has had the consequence of higher prices.

If rising demand and prices for food were the only problem, the simple solution would be to increase production. However, there are other factors at play. Two of them are climate change and the attempt to mitigate it.
