Estonia needs to move faster to reduce its dependence on oil shale so it can advance towards a greener economy and reduce air pollution and waste generation, according to a new OECD report. The OECD’s first recommends working to improve energy efficiency, buying more
clean energy from the European grid, and stepping up investment in renewable energy sources. Estonia’s attachment to oil shale mining for energy generation means it has the most carbon intensive economy in the OECD and the third most energy intensive.
“Reducing its dependence on oil shale is Estonia’s number one economic, environmental and social challenge, and it cannot afford to wait until the shale runs dry to make a start,” said OECD Environment Director Simon Upton, presenting the Review in Tallinn. “For the sake of its economy and for the health and well-being of its people, Estonia needs to find a way today to get onto a green growth path.”
Oil shale provides 70% of the energy supply in Estonia, which produced 533 tonnes of CO2 emissions per USD 1,000 of GDP in 2014, compared with an OECD average of 226 tonnes.
Estonia’s greenhouse gas emissions rose by 23% from 2000 to 2014, well below its economic growth of 64% over the period but still the third-highest increase in the OECD area after Turkey and Korea.
Estonia reached its 2020 EU target of 25% of renewable energy in gross final energy consumption early in 2011, helped by government subsidies for biomass and wind power generation and the extensive use of biomass for heating. Yet the rate of renewable electricity generation remains among the lowest in the OECD, and the economic viability of new wind projects is uncertain at today’s carbon and electricity prices.
An ambitious green tax reform agenda which aims to shift part of the tax burden from income to consumption, natural resource use and pollution is on-going. Revenues from environment-related taxes rose to a peak of 2.9% of GDP in 2010 then declined to 2.6% in 2014, leaving Estonia in the upper third of OECD member countries on this indicator. There is still ample room, however, to raise taxes on emissions and other environmental impacts.
Estonia boasts good air quality nationwide, but oil shale mining and processing in the north-eastern Ida-Viru region pollutes the air, soil and water, and people there suffer higher rates of respiratory and cardiovascular disorders.
Estonia generates 35 times the EU average in hazardous waste per capita, 98% of which comes from oil shale combustion and refining. Leachate from landfills where it is deposited, particularly Soviet era ones, contaminates groundwater. Generation of non-hazardous mining waste has risen by 40% since 2005 as the declining quality of shale requires higher volumes to be extracted.
Estonia joined the OECD in 2010 and as a member of the European Union since 2004 is now integrated into the European electricity grid. The Review’s recommendations include: Develop and implement specific climate change mitigation measures in order to achieve Estonia’s GHG reduction goals for 2030 and 2050; Lower emission intensity by tapping into European electricity markets, using more renewables in place of oil shale for energy generation, and increasing energy efficiency; Ensure that any diversification away from shale oil is socially responsible, with retraining, employment promotion and social guarantees for affected oil shale workers; Strengthen measures to reduce emissions of SOx, NOx and NH3 from the industrial power generation sector, transport and agriculture; Strengthen eco-innovation by raising firms’ (and particularly SMEs’) awareness of options for financial support and simplifying the application process.
