International maritime law conventions concerned with cargo liabilities have sought to achieve solutions which will be acceptable to a wide range of states. The Rotterdam Rules was approved by the UN Assembly on 11 December 2008. The Rotterdam Rules are intended to replace The Hague and Hamburg Rules. This paper is comparing The Rotterdam Rules with The Hague and Hamburg Rules for the carrier' liabilities and exceptions in order to find carrier' liability System, the burden of proof and exceptions in the International maritime Rules. The purpose of this paper is considering the carrier's principal recourse for defending himself inmost cargo claims. The first area analyze the transfer of carrier's fundamental Liability system in the International Rules. The second is the matter on the appointment of proof in order to establish liability or to be relieve of liability. And the third is the change of the carrier's possible exclusions from liability in the International maritime Rules. From the result of the said analysis, my paper suggests differences of the exclusions in the Rotterdam Rules comparing with the Hague and Hamburg Rules, and features of the Rotterdam Rules appling exceptions on the basis of the Hague and Hamburg Rules with regard to carrier's liability and burden of proof. The former is the inclusion of three exclusions, the deleted natural fault, and The provision making the carrier responsible for the acts of its servants or agents in the 'fire on the ship' of the Rotterdam Rules. The latter is deleting the principle of overriding obligation related to carrier's obligation of seaworthiness in the Rotterdam Rules, the burden of proof being diverted from the carrier to the carrier and the shipper in the cargo damage caused by two factors(one for which the carrier was liable and the other for which it was excusable) in the new rules.

This study investigated the reference case in the UK where legality and sustainability were systematically established for forest biomass represented by wood pellets. The UK is the country that best utilizes the trade value of wood pellets based on sustainability, with bioenergy accounting for 31% of total renewable energy production. The UK imported wood pellet, estimated 8,697 thousand tons in 2019. The UK government has continuously improved the renewable generation policy system to ensure the sustainability of wood pellets. The weighted average greenhouse gas emissions of a UK biomass power plant that received a Renewable Obligation Certificate (ROC) in 2018-19 was 26.71 gCO2e/MJ. These power plants are expected to meet the upper limit of 72.2 gCO2e/MJ by 2025. To issue an ROC, the biomass power plant must demonstrate that 70% of its total biofuel usage is sustainable. The UK uses the Sustainable Biomass Program (SBP) certification system, which is gradually expanding to other European countries, to prove the sustainability of biomass energy fuels. Global wood pellet production with SBP certification in 2019 was 10.5 Mt. This trend has significant implications for introducing additional sustainability into the wood pellet policy of South Korea.

This study set out to devise an optimized system to take into account life cycle cost(LCC) and ton of carbon dioxide($TCO_2$) by applying the weighted coefficient method(WCM) to "public-purpose" facility buildings according to the mandatory 5% and 11% of new renewable energy in total construction costs and anticipated energy consumption, respectively, based on the changes of the public obligation system. (1) System installation capacity is applied within the same new renewable energy facility investment according to the mandatory 5% of new renewable energy in total construction costs. Both LCC and $TCO_2$ recorded in the descending order of geothermal, solar, and photovoltaic energy. The geothermal energy systems tended to exhibit an excellent performance with the increasing installation capacity percentage. (2) Optimal systems include the geothermal energy(100%) system in the category of single systems, the solar energy(12%)+geothermal energy(88%) system in the category of 2-combined systems, and the photovoltaic energy(12%)+solar energy(12%)+geothermal energy(76%) system and the photovoltaic energy(12%)+solar energy(25%)+geothermal energy(63%) system in the category of 3-combined systems. (3) LCC was the highest in the descending order of photovoltaic, geothermal and solar energy due to the influences of each energy source's correction coefficient according to the mandatory 11% of new renewable energy in anticipated energy consumption. The greater installation capacity percentage photovoltaic energy had, the more excellent tendency was observed. $TCO_2$ recorded in the descending order of geothermal, photovoltaic and solar energy with the decreasing installation capacity of photovoltaic energy. The greater installation capacity percentage a geothermal energy system had, the more excellent tendency it demonstrated. (4) Optimal systems include the geothermal energy(100%) system in the category of single systems, the photovoltaic energy(62%)+geothermal energy(38%) system in the category of 2-combined systems, and the photovoltaic energy(50%)+solar energy(12%)+geothermal energy(38%) system and the photovoltaic energy(12%)+solar energy(12%)+geothermal energy(76%) system in the category of 3-combined systems.
