Citi has established combatting climate change as the top priority in our Sustainable Progress strategy, launched in February of this year. Our signature effort to combat climate change is our $100 Billion Environmental Finance goal, a goal to lend, invest and facilitate $100 billion over 10 years toward climate and environmental solutions, and we're making significant progress towards that goal. In addition to our core business activities, we are also focused on the greening of our own operations. We have set science-based environmental footprint goals to reduce our greenhouse gas (GHG) emissions by 35% by 2020 and by 80% by 2050 and to have 33% of our real estate portfolio to be LEED green building certified by 2020.
Citi's businesses are collaborating to develop innovative climate financing solutions, with all of these efforts being done to help support our clients. One example is a transaction from earlier this year, when Citi provided construction finance, tax equity and commodity hedging to support the development of the Shannon Wind Project, which will provide clean, renewable energy to Facebook's new 110-acre data center in Irving, Texas. Citi has also been a leader in the green bond market. So far this year, we have participated in over $3 billion in green bond offerings, including the recent EDF Group green bond for $1.25 billion to support their construction of renewable energy projects.
As the United Nations Framework Convention on Climate Change (UNFCCC) COP21, also known as the 2015 Paris Climate Conference, takes place in Paris through December 11, Citi continues to be engaged and supportive of strong global action on climate. Our activities this fall have included:
Through our combined efforts, we believe that Citi can play a meaningful role in climate mitigation and adaptation and in driving forward smart climate policies.
