Chapter 1 offers an overview of the book and summarizes the state and trends in climate change legislation. Making use of a unique global database, Climate Change Laws of the World, the chapter identifies over 1,200 climate change laws and policies of similar stature in the 164 countries the data covers. This stock of laws is the result of over 20 years of policy making and speaks to the growing attention that legislators are devoting to climate change. In 1997, at the time the Kyoto Protocol was signed, there were only about 60 relevant laws and policies. Countries use different routes to address climate change. In some countries the primary avenue is acts of parliament, that is, formal laws passed by the legislative branch. In others, the policy direction is defined through executive orders, decrees and strategies. Climate change laws also differ in scope and ambition. Some laws are specifically focused on climate change, advancing explicitly emissions reduction or adaptation targets. Others introduce climate concerns into sector policies, such as those on energy, or broader development plans. Understanding these different approaches becomes increasingly important as countries implement their pledges under the Paris Agreement.

While carbon tax measures have not yet met with success at the federal level in the United States, proposals for carbon taxes emerged in a handful of states in 2015 and 2016. The proposals address the shared challenge of climate change, but each has its own unique features and setting. Drawing on proposals in Oregon, Massachusetts, Vermont and Washington as case studies, this chapter explores how state constitutions can affect the design of state-level carbon taxes and their legislative route toward enactment. For example, the Oregon constitution imposes limits on tax rates and use of the revenue when taxing certain fossil fuels. The constitutions in three of the four states require that some types of revenue measures must originate in the legislative House of Representatives, not the Senate, raising the question whether carbon taxes can be designed in a manner that will avoid this procedural constraint. In Washington, the carbon tax proposal came forward as a ballot initiative that went to voters in the general election, following a procedure permitted under the state constitution. These case studies serve as an important reminder of how constitutional provisions that were not created with climate change in mind can influence the design features of subnational carbon taxes and political strategies.

The current global economic system, which is fueled by externalizing environmental costs, growing exponentially, consuming more, and a widening wealth gap between rich and poor, is misaligned to meet the climate imperative to rapidly reduce greenhouse gases (GHGs). Amidst this system breakdown as we reach the end of the Industrial Age, the new economy movement has emerged to provide an alternative approach where ecological balance, wealth equity, and vibrant democracy are central to economic activity. Laws are the fundamental infrastructure that undergirds our economic and political system. Environmental law is typically conceived as a set of rules that establish pollutant limits for specific waterbodies, protect an identified species, or direct an industry to use a required technology. Although necessary, these types of law do not address the fundamentals of our political economy, and the most dramatic failure of environmental law is seen in increasing amounts of GHGs and global climate disruption. In order to develop a new economic system that is aligned with a climate and economic justice imperative, we need laws that will facilitate the new system and discourage the old. This chapter discusses systems thinking and systems change, highlighting leverage points to achieve change. It gives an overview of the new economy movement that has emerged to provide a new narrative, and using a systems lens, identifies areas where the law needs to evolve to facilitate building a more sustainable, equitable, and democratic future.
