warming due to increases in greenhouse gases. One study suggests that the early warming could be due to a combination of anthropogenic effects and a highly unusual internal variation. Thus the early century warming could be due to some combination of natural internal variability, changes in solar irradiance and some anthropogenic influence. The additional warming in the second half-century is most likely to be due to a substantial warming due to increases in greenhouse gases, partially offset by cooling

Unilever has diversified in other food businesses, and uses innovation with his launch of Cornetto Love Discs (a cone with a thick chocolate disc) and according to the website mintel mars is “developing an ambient ice cream in an attempt to reduce greenhouse gas emissions. The low-carbon product which is being designed with Cambridge University”. (Website mintel oxygen) Another example of innovation is Ben &Jerry’s latest launch of a frozen yogurt extention to the Phish food ice cream in 2009. (Website

method, we assessed the environmental impact of virgin PET (produced from oil in Saudi Arabia) and recycled PET. Results for recycled PET were extremely positive: • Production of 1 kg virgin PET Ǡ 5.2 kg greenhouse gas (CO2 equivalent) • Production of 1 kg recycled PET* Ǡ 1.9 kg greenhouse gas (CO2 equivalent) Use of fossil resources: 1 kg of recycled PET saves approximately 2.3 kg of fossil resources over production of 1 kg virgin PET. The resource saving applied to the output of the Freudenberg

such, the usual procedures of European decision-making did not apply at this stage, but the interest groups exclusively dealt with the European Commission. The main purpose of the ECCP was to come up with cost-effective measures to reduce greenhouse gas (GHG) emissions, enabling the European Union to fulfil the Kyoto requirements. It was to consist of a steering committee and a number of working groups (Commission of the European Communities 2000a). These working groups were to concentrate initially

and reverse land degradation processes. Climate Change is the most serious global environmental issue and a potential threat to human survival in the long-term. The global climate is undergoing rapid change due to the increasing concentration of greenhouse gases (GHGs)- chiefly Carbon Dioxide -- in the atmosphere. The increase in global temperatures will be accompanied by rising sea levels and a potential increase in climate variability, such as extremes of temperature, precipitation and storm activity

If emissions are not reduced to levels significantly lower than those currently registered, warming

outside the barn in a pit of concrete for one year. Thereafter, the material will be applied in the field to fertilize farmland. The manure produced odors and toxic gases, composed mainly of methane, which is part of the main greenhouse gas. To reduce these greenhouse gases, a processing technique called natural substrates (Methanisation) was developed to treat various types of waste and this, in anaerobic conditions without oxygen. This technique of methanisation proceeds in called isolated
