An extensive data set on energy, economy, environmental pollution and institutional quality in the petroleum-reliant developing and transition economies.

Petroleum-reliant developing and transition economies account for 15-20% of global greenhouse gas emissions. This group of countries have a disproportionately high share of oil and natural gas in their energy mix and a relatively high carbon footprint over their petroleum value chains. The present data set is an extensive compilation of the essential indicators related to economy, energy, environmental pollution, and institutional quality of 37 oil and gas producing developing and transition economies in the time interval spanning between 1989 and 2019. The data set can serve as a basis for the macroeconomic analysis of energy, environment, social and institutional issues in this group of countries and draft further industry explorations as well as sustainable development policy analyses and recommendations. Furthermore, based on the mentioned data series, we propose three novel indexes - i.e. Energy Sector Development Indexes I, II, and III. Those indexes are developed in the context of fossil fuel abundant settings. Despite focusing on the fossil fuel abundant settings, the Energy Sector Development Indexes could be expanded for petroleum and coal scarce countries as well.
