Since the Paris Agreement's adoption in 2015, a majority of the world's largest investors have begun to take action on climate change. According to a new report, the 2016–2017 year showed an average improvement in decarbonization within all major investor categories except pension funds.

The outcome of the December 2011 United Nations climate negotiations in Durban, South Africa, provides an important new opportunity to move toward an international climate policy architecture that is capable of delivering broad international participation and significant global CO2 emissions reductions at reasonable cost. This paper addresses an important component of potential climate policy architecture for the post-Durban era: links among independent tradable permit systems for greenhouse gases.

This paper offers a detailed plan to set quantitative national limits on emissions of greenhouse gases, building on the foundation of the Kyoto Protocol. It attempts to fill in the most serious gaps: the absence of targets extending as far as 2100, the absence of participation by the United States and developing countries, and the absence of reason to think that countries will abide by commitments. The plan elaborates on the idea of a framework of formulas that can assign quantitative limits across countries, one budget period at a time. Unlike other proposals for century-long paths of emission targets that are based purely on science (concentration goals) or economics (cost-benefit optimization), this plan is based partly on politics.

The Harvard Project on International Climate Agreements has agreed to help the Office of the Danish Prime Minister, in its role as incoming President of the 2009 Conference of the Parties, to prepare background papers and on-site briefings for a series of very high-level dialogues on climate change policy, hosted by the Prime Minister. These dialogues will each include about 25 participants, including CEOs of European and U.S. corporations, key officials from national governments and intergovernmental organizations, and leaders of major environmental NGOs. This paper on the subject of economic incentives was prepared by the Harvard Project leadership for the first dialogue.

The Bali climate change conference was a qualified success. Before we went to Bali, we observed that it will be good news if there’s no bad news coming out of the negotiations.  This was achieved, and then some.

"With tradable permit systems for greenhouse gas (GHG) emissions in place in some parts of the world and actively being considered in others, increasing attention has been given to the opportunity to link these systems. Linking occurs when the government that maintains one system allows regulated entities to use allowances or credits from another system to meet domestic compliance obligations."
