Environmental Policy and Law, 49/(4-5) (2019) that the emission reduction outcome of a carbon tax is not pre-defined, but the carbon price is". See http://www.worldbank.org/en/programs/pricing-carbon. The first instance of a carbon tax was in January 1990 in Finland. Finland's initiative was followed by Sweden, Norway, the Netherlands, Denmark, Italy and the UK. Some Canadian provinces have followed with carbon taxes (e.g., Quebec in 2007 and British Columbia in 2008), as well as a few areas in the US (e.g., Boulder, Colorado in 2007 and Bay Area Air Quality Management District, California in 2008). 18 One interpretation of environmental integrity is the sustenance of important biophysical processes which support plant and animal life, and which must be allowed to continue without significant change. The objective is to assure the continued health of essential life-support systems of nature, including air, water and soil, by protecting the resilience, diversity and durability of the ecosystem. It is difficult to argue that a carbon tax, which could discourage pollution, would distort the balance of nature. 19 Lang, C. 2016. "Why not put a carbon tax on aviation rather than relying on REDD offsets? Because a tax lacks 'environmental integrity', says ICAO's Jane Hupe". REDD, 12 April.

Investment law is an urgently required regulation to regulate an investment activity. Hence the formulation within those laws has not yet provided a balance protection for all parties; those are the home countries, host countries and investors. The investment law itself regulate by 3 different kinds of laws, that is the customary international law, national law and contract law. Regulating investment activities in host states will have to consider the customary international law, as the international framework. This law is applicable due to the different jusrisdiction involved within the business activities. Indonesia investment law regulation firstly introduced by law number 1/1967 concerning foreign direct investment. Subsequently, it was amended by law number 25/2007 concerning Investment Law. However, some research has to be carried out regarding the protection of the parties. This research analysed the principle of proportionality interest protection to provide a fair protection of parties. Eventually, the protection of the state as host country and investors as the alien in host country.This research is a normative legal research, which use statute approach, historical approach and conceptual approach to determine the principle that could be used to maximize the protection of actors within the investment activities in Indonesia.

Law No 11/2020 concerning Job Creation (Omnibus Law’) mandates the use of domestic raw materials for all industries in Indonesia. Following the passage of the Omnibus Law, Indonesia issued Government Regulation No 28/2021 concerning Industrial Management and Presidential Regulation No 12/2021 concerning the amendment of Presidential Regulation No 16/2018 concerning Government Procurement of Goods and Services. Both regulations oblige all industries in Indonesia to use domestic raw materials pursuant to the Omnibus Law. In investment law, this kind of policy could lead to indirect expropriation because when an investor makes an investment in a host country, the raw material and machines for production might come from their home state or other states. Furthermore, a public-private partnership contract with investors funding infrastructure projects for at least 50 years using materials agreed upon in advance will lead to indirect expropriation. The method used in this research was legal research theory with statute and conceptual approaches. From this research, the policy of the Indonesian government can be described as indirect expropriation because the regulation is effective and enforced.
