UPSTREAM METHODS
Embodied Energy Analysis Accounts for the total commercial energy directly and indirectly used up over the production chain of a product. It is also a proxy for a process contribution to the depletion of fossil fuels. (Herendeen, 1998)
Emergy SynthesisEmergy is the total amount of available energy of one kind (usually solar) that is directly or indirectly required to make a given product or to support a given flow. Due to its reference to solar energy, it is also used as a measure of environmental support. (Odum, 1996)
Material Flow Accounting Accounts for the materials directly and indirectly supplied to a process, and diverted from their natural pattern. TMR has been suggested as a measure of environmental disturbance, so-called “environmental backpack”. (Hinterberger and Stiller, 1998)
CML 2 (baseline 2000) Method Withdrawals and emissions are assigned to ecological impact categories. Environmental impacts associated to airborne, liquid and solid emissions by a process are evaluated and described by means of appropriate indicators. Indicators are based on equivalency factors to reference compounds, the contribution of which to the relative impact category is well known. (Centre of Environmental Science of Leiden University, NL, 2001)
Eco-indicator 99 method. Withdrawals and emissions are assigned to three main impact categories (Human health, Ecosystem Integrity and Resource depletion). Indicators are based on impact factors from previous ecological, ecotoxicological and resource availability studies.

CONCLUSIONS:
Monitoring energy and material costs over time would allow to ascertain to what extent the Park management is resource-efficient
The Bory Tucholskie National Park showed a good environmental performance but a problem arises when the focus is placed on the economic self-sufficiency. Nevertheless assessing the benefits of a park only in terms of economic return prevents a proper understanding of the complexity of ecosystem services
If the emergy equivalent value of the investment from Government, is compared with the emergy value of the business generated (fishery, hunting, forestry and tourism) as well as the emergy values of the ecosystem services, and biomass standing storage, it comes out that business, ecosystem services and biomass storage are respectively 3.7, 2.4 and 91 times the governmental investment. This result confirms the advantage and benefits of investing into natural capital conservation.
