Abstract Natural gas resources production in Russia is profitable, both economically and in terms of the energy produced. In 2017, the Gazprom Return on Energy Investment (further- EROI) for the production, transportation, and processing was 79:1 that is a high level of the coefficient, and Energy Savings' scale (further – ES) constantly under enhancing. However, nowadays for Russian gas companies, there is an urgent question about EROI and ES transversal links with other sustainable factors. Which financial and non-financial factors can lead to the highest level of energy sustainability? In the Research Authors regard Energy efficiency growth as the result of the transversal processes with financial resources affecting the Company's technical innovation state, ecological environment, and social responsibility. Three energy efficiency models with forecasts till 2030 were built. The optimal EROI model shows a forecast trend under the influencing Return on Labor, Net Profit growth, and Research and Development expenses. Energy Savings models' forecast were built under the influencing Higgins sustainable growth rate, social and environmental expenses, and Research and Development expenses.
