Most European countries have signed the United Nations Framework Convention on climate change and its Kyoto Protocol. Because the European Union is a party to the convention just like the individual countries, there is a need for harmonizing emissions reporting. This specifically applies to the Land Use, Land-Use Change, and Forestry sector, for which harmonized reporting is complex and generally challenging. For example, parties use a variety of different methods for estimating emissions and removals, ranging from application of default factors to advanced methods adapted to national circumstances, such as ongoing field inventories. In this study, we demonstrate that without harmonization, national definitions and methods lead to inconsistent estimates. Based on case studies in Finland, Germany, Norway, Portugal, Slovenia, and Sweden, we conclude that common reference definitions and country-specific bridges are means to harmonize the estimates and make greenhouse gas reporting from forests comparable across countries.

In the present study we evaluated the effect of phenological stage at harvest and drying temperature on the content of secondary metabolites in six year old cultivatedclones of Rhodiola rosea. The experimental work was performed in cooperation between MTT in Finland and Bioforsk in Norway. In spite of the differences in growing season, we found similar development in biomassproduction and content of secondary metabolites in the two field experiments.During the period with intensive shoot growth the dry weight of the rootdecreased until budding / full flowering followed by an increase towards thelast harvest after wilting. The % dry matter followed the same development. The content of total rosavins in the dry rhizomes was highest at flowering at both sitesand the average content for spring was 24 % respectively 21% higher than inautumn in Finland and Norway (P=0,002). In Finland the average content of salidroside in spring of the dry rhizomewas 68 % higher than in autumn. While in Norway there were no differences insalidroside content at the different phenological stages (P = 0,097), lowvariation in the content of cinnamic alcohol at both sites was observed, but atendency to a small increase after flowering. The content of total rosavins was significantly higher at drying temperatures at or below 50˚C (P
