Only with such widespread use of economic instruments will it be possible to tackle the more complex, interrelated and international environmental problems of the future, says the organization which groups 30 member countries that produce two-thirds of the world's goods and services. Large tuna like this one caught in 1998 in Stintino, Sardinia, Italy, are becoming increasingly rare. In this, environmental pressures, environmental states and society's responses are classified as red light, yellow light or green light issues. The main conclusions were finalized over a year ago.

Tropical deforestation continues at alarming rates.
Non-OECD regions will lose another 10 percent of their forests by 2020. Human induced climate change already affects weather patterns worldwide. This will worsen as OECD CO2 emissions increase by a projected one-third to 2020. Urban air quality and associated health problems are deteriorating in many OECD countries. Energy use and transportation are already the main contributors to greenhouse gas emissions and air pollution.
