Organised by the International Energy Agency Greenhouse Gas Research and Development Programme, the International Conference on Technologies for Activities Implemented Jointly was held in Vancouver, British Columbia, Canada, May 26-29 (1997). The papers presented at the conference and published in these proceedings reflect the theme that Activities Implemented Jointly (AIJ) is a major tool to facilitate practical demonstration and development of greenhouse gas mitigation technologies. Published in a single volume under the title Greenhouse Gas Mitigation, the proceedings cover the following key areas: Key Note Presentations; International Initiatives; Enhancing Sinks and Stores; Maximising Joint Benefits; Improved Energy Technology; Asian Development Bank; Transport; Transmission and End Use. The concept of AIJ will facilitate international cooperation to reduce greenhouse gas concentrations and mitigate effects of climate change. In publishing these internationally-relevant conference proceedings, Greenhouse Gas Mitigation is likely to prove an invaluable reference tool for those engaged in research and application of initiatives to combat climate change.
