(ANSAmed) - BRUSSELS, 26 APRIL - The EU Commission gave an ultimatum to Italy and Malta on the fight to climate change: the two countries must comply with the laws on fluorinated gases, powerful greenhouse gases contained in air conditioners, refrigerators and isolating foams. The European executive has asked to send a reasoned opinion: if Rome and Valletta fail to give a satisfactory response within two months, the cases might be referred to the EU Court of Justice. Contrary to the Regulation's requirements, Italy and Malta have not notified the Commission of their training and certification requirements for companies and personnel involved in activities concerning fluorinated greenhouse gases. Italy has also failed to notify its rules on penalties in case a provision of the Regulation is infringed. The EU is acting on two fronts: avoiding fluorinated greenhouse gases in some applications in which more environment-friendly and cost-effective alternatives are available and reducing leakage from equipment containing fluorinated greenhouse gases. Measures include: labelling of equipment, training and certification of companies and personnel handling such gases, containment and recovery. (ANSAmed).
