and invite other countries to follow suit. · (d) We welcome particularly the IPCC workshop to be held in London, which will discuss, in fulfilment of the remit of the Noordwijk declaration, the feasibility of achieving targets to limit or reduce co2 and other energy-related greenhouse gas emissions, and the technical and methodological issues involved in setting such targets. With respect to the differences between nations and regions, the economic impacts of imple"-enting these proposals must be evaluated. One· promising approach in formulating national commitments seems to be to consider a trade-off in reduction targets between different greenhouse gases and the sustainable use of the biotic carbon reservoirs. United Nations ECE Governments should w, in the context of the framework convention to include the examination of pos~ , mechanisms for achieving agreed targets for co2 emissions and other / ...

(e) Some policies are justified in their own right and should be pursued. All countries of the ECE region should pursue actions to phase-out CFCs; vigorously promote energy efficiency; encourage shifts to less polluting energy sources such as natural gas and renewable sources; · and give high priority to promoting ecologically sound net forest growth.

(f) All ECE countries should wc,rk towards the reduction of SO2 and NOx emissions and other transboundary air pollutants to ensure that local and regional 
**Analysis**
The text appears to be focused on environmental issues, particularly climate change and air pollution, and the need for international cooperation to address these issues. It also touches on economic aspects, such as the evaluation of economic impacts and the need for increased funding for research and development. The text does not seem to be primarily concerned with social or cultural issues.
