By 2015 the CO2 emissions from the capital of Denmark will according to the plan be reduced by 20 percent, leading to a carbon neutral capital ten years later.

The city suggests several ways to reach its goal: Streets are to be humming with electric and hydrogen-powered cars which park for free and recharge on street corners, roofs are to be covered by plants, wind power capacity will grow, schools will teach climate end private enterprises will be offered counselling on CO2 reductions.

Thirteen percent of Copenhagen’s electricity is produced by wind turbines today. By 2025 the ambition is that wind turbines will be producing it all.

2015:

Objective: Copenhagen has resolved to reduce its CO2 emissions by 20 % in the period 2005-2015.

• This equates to a reduction from approx. 2.5 million tons to approx. 2 million tons of CO2.

• The objective will be achieved through the 50 specific initiatives outlined in the climate plan.

2025:

Vision: Copenhagen to be CO2 neutral by 2025.

•  Copenhagen will be CO2 neutral when the city’s net emissions of CO2 are zero. In other words, when Copenhagen has reduced its CO2 emissions to a minimum and offset the remaining emissions through initiatives outside the city (e.g. via wind turbines).

•  The vision will be realised by implementing even more measures than those in the climate plan. For example, by installing even more wind turbines, doing even more to limit emissions from cars and buses, or by encouraging even more inhabitants of Copenhagen to save energy.
