Answer: The EU has a number of directives and regulations related to climate change as part of its ambitious environmental policy. Here are some of the key documents:

1. European climate policy:
   • European Green Deal: This ambitious plan sets the goal of achieving climate neutrality by 2050. It contains various measures to promote a sustainable economy, biodiversity protection, clean energies and a circular economy.
2. Regulation on the European Climate Law (European Climate Law):
   • Adopted in 2021, this law legally enshrines the goal of achieving climate neutrality by 2050.
3. EU Emissions Trading System (EU ETS):
   • One of the EU's main strategies for reducing greenhouse gas emissions. This system sets a limit on the total amount of emissions and enables the trading of emission quotas.
4. Energy Efficiency Directive:
   • It establishes binding measures to improve energy efficiency and the goal of achieving at least 32.5 % improvement in energy efficiency by 2030.
5. Renewable Energy Directive:
   • It sets the goal of achieving a 32 % share of renewable energy sources in total energy consumption in the EU by 2030.
6. Regulation on the reduction of greenhouse gas emissions (Effort Sharing Regulation):
   • It sets binding targets for individual member states to reduce greenhouse gas emissions in sectors outside the EU ETS, such as transport, buildings and agriculture.
7. Air Quality Directive:
   • It sets limits for concentrations of harmful substances in the air to protect human health and the environment.
8. Package of measures "Fit for 55":
   • The package includes various legislative proposals to put the EU on track to reduce greenhouse gas emissions by 55 % by 2030 compared to 1990 levels.

These regulations and directives are only the tip of the iceberg when it comes to the EU's comprehensive approach to tackling climate change.
