A key objective of TAIEX is to accelerate the enlargement process, helping candidates align with EU laws and implement the essential reforms required for EU membership. Classical TAIEX assistance or support via the Environment and Climate Regional Accession Network (ECRAN) is provided to the beneficiaries in all fields covered by the environmental legislation (air quality, waste management, nature protection, chemicals, industrial pollution and climate change). Environment and energy are key policies closely linked as production of energy has an impact on the environment and the climate. The topics addressed go from renewable energy and energy savings to market liberalisation in the oil, gas and electricity sectors. In the area of transport, sectors covered include maritime, inland and aviation including joint programmes with the European Maritime Safety Agency (EMSA) and the European Civil Aviation Conference (ECAC).
