Environmental risks, in particular climate change and environmental pollution, are among the key challenges faced by modern governments nowadays. Environmental risks are associated with specific costs and expenditures necessary to mitigate their negative effects. In this context, the financial system plays a significant role, particularly the public financial system, which allocates and redistributes public resources and has an impact on market participants by imposing environmental taxes. This study assessed the interdependence between environmental degradation and public expenditure, financial sector development, environmental taxes, and related socioeconomic policies. The aim was to diagnose and define the relationship between environmental degradation and sustainable fiscal instruments used in the financial system. The original research approach adopted in the study is the inclusion of variables representing a sustainable approach to assessment of the financial system. Two groups of European Union countries were analyzed for the period 2008–2017, namely, converging economies from Central and Eastern Europe and the largest developed economies of Western Europe. The authors found a strong relationship between greenhouse gas emissions and fiscal instruments, especially expenditure on research and development, and the development of the financial sector. In the case of environmental taxes, their impact differed depending on the country, being predominantly beneficial in countries with higher greenhouse gas emissions but unfavorable in countries with lower emissions levels.

Several studies have examined the relationship between environmental performance and economic development. However, most of them did not take sustainable development and financial development into account. The study argues that sustainable financial and economic development contributes to reducing greenhouse gas emissions. We use the panel data regression model to capture the relationship between greenhouse gas emission and sustainable economic and financial development. The panel data refers to the period of 2007–2017. The EU 25 countries were analysed. The results show that the relationship between sustainable financial development and environmental degradation is more relevant for converging economies than developed countries. We found that the variable “energy productivity” has the strongest impact on greenhouse gas emissions for both country groups (converging and developed); however, it increases for developed countries and it decreases the greenhouse gas emissions for converging economies. We also found that environmental taxes are an efficient instrument that mitigates greenhouse gas emissions, especially in developed countries group.

The local government (LG) sector plays an important role in the EU economies. Besides providing a vast range of public services, it accounts for over 8% of total investment. The crisis, which started in 2008, resulted in increased LG indebtedness and raised concerns over the sector's debt repayment capacity. This paper proposes an alternative methodology of risk assessment of LGs to statutory debt limits, the Altman model and non-financial indicators. Firstly, it employs a corporate finance approach to evaluate the financial standing of individual entities. The measures are based on free operating cash flow and net debt. Next, Data Envelopment Analysis is used to derive the relative performance of LGs in debt utilization. The indicators used are available from the LG financial reports and also allow risk to be monitored on a quarterly basis. The proposed approach allows the ranking of the risk of individual LGs according to both their debt service capacity and long-term ability to manage costs and carry out a rational investment policy. The results obtained using the DEA method also enable the identification of LGs with persistently inferior risk profile. The quantitative analysis is conducted for the local governments in Poland for the period 2008-2015.

The financial standing of local governments across the European Union was strongly affected by the economic crisis. The local government sector conducted vast investment policies reaching 10.2% of all investments in the EU countries in 2010. However, at the same time its indebtedness expanded significantly. The current low interest rate environment makes the sector vulnerable to future interest rate increases. The presented research analyses the impact of several scenarios of interest rate changes in Poland on the local governments’ ability to service their current debt burdens. Simulations are conducted with the Monte Carlo method. Some scenarios indicate a high vulnerability of local governments to adverse changes in market interest rates, but only if they are combined with a reduction of sector’s operating surplus. Such an economic setup may give rise to systemic problems for the whole public sector.
