We need to reduce our carbon emissions – that much we know. But how? We already know that too – through numerous different measures. The European Commission has calculated that the building sector alone is responsible for 36 percent of energy consumption and around 25 percent of carbon emissions in the EU. That is a huge amount, and it’s a lever we need to be using. So in 2020 the EU called for a “renovation wave” with the aim of lifting the rate of renovation from 1 percent a year to 3 percent a year by 2030. And where are we now? According to current statistics, the annual renovation rate is 1.2 percent. To put this in perspective, that equates to a comprehensive renovation every 100 years or so. In other words, much too slow if we want to reach climate targets. And now? It is high time for efficient refurbishment methods, such as Finstral’s slide-in installation. Because simply replacing old windows saves up to 90 million tonnes of CO2 a year. And that represents 20 percent of all potential savings in the building sector. Across Europe.
