Environmental law is a complex legal field involving the protection and use of natural resources in both private and public spaces. Policies and regulations vary and intersect across regional, national and international levels; relevant issues can range from energy and pollution to climate change and wildlife conservation.

Given its multifaceted and evolving nature, it's important to receive accurate and up to date information on this subject. So, we've compiled a list of some of the best environmental law feeds on Twitter that will help keep you informed.

The list is based on Twitter data culled according to content, follower/following ratios, frequency of tweets, blog popularity, the opinions of other environmental law experts and influencers, as well as our own subjective judgment.

Note that some influential voices are not included, either because they don't have active Twitter accounts or because they only tweet about environmental law sporadically. Here, our goal is to provide the best possible stream of environmental law news, analyses and insight.
