Energy and environmental issues relating to greenhouse gas emissions in Turkey

States have played a leading role in protecting the environment by reducing emissions of greenhouse gases (GHGs). State emissions are significant on a global scale. CO2 and CO are the main GHGs associated with global warming. At the present time, coal is responsible for 30-40% of the world CO2 emissions from fossil fuels. SO2 and NOx contribute to acid rain. Carbon assessments can play an important role in a strategy to control carbon dioxide emissions while raising revenue. In 1992, Turkish Ministry of Environment issued a regulation providing for emissions testing for cars, trucks and vans. (C) 2002 Elsevier Science Ltd. All rights reserved.
