EU member states are providing limited information on the actual effects and costs of their policies to reduce greenhouse gas emissions.
That’s according to the European Environment Agency (EEA), which found their reports often lack quantitative information on the results of the regulations and measures that aim to mitigate climate change.
Last year, only nine member states reported information on the emissions reductions “over a mere 65 policies and measures”, which means there is not enough data to calculate the exact impacts of current national mitigation policies across the EU, it warns.
The EEA adds it is necessary to combine several different sources of information to properly analyse the effectiveness of individual schemes or the aggregate impact of sectoral measures in curbing emissions.
It believes the effective evaluation of current policies is important to support “better and more informed” decision-making for future policies.
Most reported policies and measures are economic, such as direct subsidies or Feed-in Tariffs or regulatory such as energy efficiency standards. Three out of four (74%) national policies had a direct link to EU legislation.
The EEA’s data also reveals 28 member states have jointly reduced greenhouse gas emissions by 22.4% from 1990 to 2016.
The joint EU target is to cut emissions by at least 20% by the end of the decade and by at least 40% by 2030.
