The article states that in the conditions of climate crisis aggravation the decarbonisation of the economy acquires the status of a global initiative aimed at achieving zero CO2 emissions by 2050. It is emphasised that this initiative is closely accompanied by legislation, business modernisation programmes and the creation of equal conditions for both domestic producers and exporters of carbon-intensive products (in particular, through the introduction of the carbon border adjustment mechanism – CBAM) and new rules of the world market. The consequences of CBAM implementation into Ukrainian metallurgical enterprises and the development of their foreign economic activity are determined in the example of Metinvest Group (Ukraine) enterprises. The ambivalence of CBAM is proven. It is substantiated that CBAM implementation will not accelerate, but, on the contrary, will slow down the process of decarbonisation, which will eventually lead to the loss of domestic metallurgical enterprises’ competitive position in the European market of metal products. Regarding the need to take transitional measures to decarbonise the metallurgical business (first of all, to ensure proper investment), the decision should be based on the expected decoupling effect – positive dynamics of economic growth while reducing the negative impact on the environment. The estimating method of the decoupling effect has been modified according to the integrated approach. A trend analysis of the integrated decalin effect indicator and its components was performed in Metinvest Group companies (Ukraine). Based on the results of econometric analysis of the impact of investment on greenhouse gas emissions, the author’s model for determining the volume of investment in the process of decarbonisation of metallurgical enterprises for the period up to 2050 is proposed. Comparative analysis is performed regarding investment in the process of decarbonisation under the scenarios by GMK Center, IEA, McKinsey and Roland Berger, as well as the author’s model.

Population of Indonesian around 265,015,300 people, so they need a huge amount of food. Rice is the most important food staple, but it is still imported around 500,000 t to stabilize the price in Indonesia. However, the country’s import of wheat is approximately is greater than 10,000,000 t. Hunger reduction and poverty eradication are the top priorities under SDGs (Sustainable Development Goals). Production of food based on cereals and grains was inert. Thus to meet the global claims root-crops, particularly cassava, has the potential to be explored. Cassava originated from tropical Latin America; it was distributed to Asia and Africa after Columbus discovered America in the 15th century. Early distribution of cassava was only across the longitude; recently its distribution is athwart the latitude. Literature review as well as arena reflection were used to gather information to meet the methodology in this research. Increasing productivity to meet the demand of food, feed, and other industrial needs with prosperous communities is considered an endless charity which requires a solid global cooperation. Price fluctuation was a factor affecting cassava progress; however, it was neglected by the government.
