In 2013, Kaine supported oil and gas exploration off the coast of Virginia, saying, "I have long believed that the moratorium on offshore drilling, based on a cost-benefit calculation performed decades ago, should be reexamined." In April 2015, Kaine reiterated his opposition to the moratorium on offshore drilling. In March 2016, Kaine signaled that his position was softening, saying he was "particularly struck by the material objections of the Department of Defense to the incompatibility of drilling with naval operations off Virginia's coast... I have participated in this debate for over a decade as a governor and member of the Senate Armed Services Committee. The DOD has been relatively quiet during this public debate and has never shared their objections with me before." By August 2016, Kaine stated his support for a ban on offshore drilling, bringing his position in line with Hillary Clinton's and the Obama administration's. Kaine supports the development of solar energy and offshore wind turbines. Based on his votes on environmental issues in the Senate, the League of Conservation Voters has given Kaine a 95% score for 2018, and a 94% lifetime score. (At the time of his vice-presidential campaign, Kaine had an 88% score for 2015, and a 91% lifetime score.) In March 2019, Kaine was one of 11 senators to sponsor the Climate Security Act of 2019, legislation forming a new group within the State Department that would be responsible for developing strategies to integrate climate science and data into operations of national security as well as restoring the post of special envoy for the Arctic, which Trump had dismantled in 2017. The proposed envoy would advise the president and the administration on the potential effects of climate on national security and be responsible for facilitating all interagency communication between federal science and security agencies. In April 2019, Kaine was one of 12 senators to sign a bipartisan letter to top senators on the Appropriations Subcommittee on Energy and Water Development advocating that the Energy Department be granted maximum funding for carbon capture, utilization and storage (CCUS), arguing that American job growth could be stimulated by investment in viable options to capture carbon emissions released into the atmosphere and expressing disagreement with the Trump's 2020 budget request to combine the two federal programs that include carbon capture research. Financial regulation Kaine strongly supports financial regulation and the Dodd–Frank Wall Street Reform and Consumer Protection
