Lightouse city: Cologne
A website about the GrowSmarter project is also available in German on the Koeln site, click here.
Situated on the banks of the river Rhine, Cologne is the fourth largest city in Germany and home to key players in business and industry. The city is committed to the European Union’s goal of achieving a 20% reduction in greenhouse gas emissions, a 20% increase in the share of renewable energy and a 20% increase in energy efficiency by 2020 based on 1990 levels. It aims to reduce carbon dioxide even further, with a 50% reduction target by 2030.
In order to achieve these goals, Cologne is looking to work closely with local industry. Areas of focus include sustainable mobility, energy efficiency of buildings, low-emission heating facilities and ensuring an integrated infrastructure as the city expands.
In 2018, the Stegerwaldsiedlung area of Cologne's smart district was awarded as being part of 100 Climate Protection Housing Estates in North Rhine-Westphalia.
