Foto ANP / Lex van Lieshout Wetenschap Biobrandstof is minder goed voor natuur en milieu dan in brede kring wordt aangenomen. Dat meldt NRC Handelsblad vandaag. De productie van biobrandstof uit gewassen als koolzaad, tarwe en soja leidt waarschijnlijk zelfs tot een netto verhoging van de uitstoot van broeikasgas. Dat komt onder meer doordat de benodigde akkergrond, bemest met stikstofhoudende kunstmest, een deel van die stikstof weer uitstoot in de vorm van N2O, lachgas. Die uitstoot is volgens recente berekeningen van onder anderen de Nederlandse Nobelpijswinnaar Paul Crutzen (Scheikunde, 1995) zo’n twee keer zo groot als tot nu toe in berekeningen als richtwaarde werd aangenomen.
De Europese Unie streeft tot nader order naar 10 procent vervanging van benzine en diesel door “hernieuwbare brandstoffen” in het jaar 2020. Lees meer over: atmosfeer. Carbon group seeks to open U.S. to global offsets. NEW YORK (Reuters) - A greenhouse emissions business group hopes to shape U.S. climate change legislation to include broad use of international carbon offsets, like wind and solar power farms in developing countries, that are not currently in the leading climate bill. In a letter sent on Wednesday to Rep. John Dingell, a Michigan Democrat, the International Emissions Trading Association, a carbon business group, said clean project offsets encourage developing countries to participate in international carbon markets, leading to "greater climate protection at lower cost. " Dingell, the chairman of the House of Representatives Energy and Commerce Committee, said in January he hoped to draft climate change legislation as soon as possible.
In greenhouse gas markets, polluters can buy credits representing emissions reductions in order to meet limits mandated by governments where they operate. But others believe the quality of offsets has been regulated well through methods used by the U.N.' US Ready To Accept Binding Emissions Obligations · Environmental. The U.S. is ready to accept “binding international obligations” on reducing greenhouse gas emissions, according to James Connaughton and Daniel Price, environmental and economics advisers to President Bush, BBC reports. The Bush administration wants some kind of binding commitment from major developing countries such as China, India and Brazil. “The U.S. is prepared to enter into binding international obligations to reduce greenhouse gases as part of a global agreement in which all major economies similarly undertake binding international obligations,” said Price, the president’s deputy national security adviser for international economic affairs.
On the heels of this announcement, EU environment commissioner Stavros Dimas has traveled to the U.S. for talks on a possible binding international agreement on reducing greenhouse gases, The Australian reports. An agreement could be announced “in conjunction” with the G8 summit of the world’s must industrialized nations in Japan in July. CO2-uitstoot verkeer rijst de pan uit.
