Xiuhtezcatl Martinez

Martinez was born in Colorado, but moved to Mexico in his infancy. As of 2019, he lives with his family in Boulder, Colorado. His mother, Tamara Roske, was the one of the founders of the Earth Guardian Community Resource Center, a high school in Maui, Hawaii. Roske serves as Executive Director of Earth Guardians. Martinez has two younger siblings, sister Tonantzin, and brother Itzcuauhtli. His father, Siri Martinez, is of Aztec heritage, and he has raised his children in the tradition of the Mexica (one of the native peoples of México). His family has transferred the traditional knowledge of seeing an individual as part of a greater whole, and emphasizing connection between all aspects of the natural world.

Martinez asserts that education and young people are key elements of the movement for significant social and environmental change: "The marching in the streets, the lifestyle changes haven’t been enough so something drastic needs to happen. The change that we need is not going to come from a politician, from an orangutan in office, it’s going to come from something that’s always been the driver of change – people power, power of young people.” When addressing the criticism of young people overusing technology in a 2016 interview with Bill Maher, Martinez noted that technology also brings people together to focus on a shared concern: "I think it’s an important tool that we have for networking and connecting with people. Social media and technology – it’s either a downfall and distraction for our generation, or a powerful tool we can use.”

In April 2019, Martinez wrote an op-ed in TeenVogue endorsing Bernie Sanders for President, stating, "I believe Bernie Sanders has our back on climate change". In December 2018, Martinez spoke with Sanders at a town hall event called "Solving the Climate Crisis".

In 2018, he and 13 other youths filed another lawsuit, this time against the state government of Washington. He is the lead plaintiff in this Martinez v. Colorado Oil and Gas Conservation Commission case. The lawsuit has been dismissed by King County Superior Court Judge Michael Scott.

In December 2018, Remezcla named Martinez in their list of "30 Latinxs Who Made an Impact in Their Communities in 2018".

Martinez recently released his first solo album, Break Free was released in the spring of 2018 featuring songs like "Sage Up" and "Young". He worked with artists such as Nakho, Shaliene Woodley, and Tru along with his younger sister who is featured in most of his music, Tonantzin Martinez.

In 2018, he received a Generation Change Award at the MTV Europe Music Awards.

In 2017, he was included on Rolling Stone's "25 under 25 list"' of young people who will change the world.

Martinez has spoken to large crowds about the effects of fossil fuels on the indigenous and other marginalized communities. He has spoken at the United Nations several times, and he gained popularity after delivering a 2015 speech at the United Nations General Assembly in English, Spanish and his native language, Nahuatl.

Martinez is one of 21 plaintiffs involved in Juliana v. United States, a lawsuit filed against the U.S. government for failing to act on climate change. The lawsuit was filed in 2015, and a federal court rejected the government's move to dismiss the case in November 2016. Martinez is also one of seven plaintiffs in the Martinez v. Colorado Oil and Gas Conservation Commission case; that case is a state-level lawsuit similar to Juliana v. United States.

As a teenager, Martinez has given three TED talks and was invited to speak before the United Nations on environmental policy. In June of 2015, he spoke at the age of 15 in English, Spanish, and Nahuatl before the UN General Assembly on Climate Change. Martinez urged immediate climate action saying, “What’s at stake right now is the existence of my generation."

In 2015, Martinez and 21 other youths filed a lawsuit against the US Federal government, Juliana et al. v United States et al. They argue that the federal government is denying their constitutional right to life, liberty and property by ignoring climate change. The plaintiffs also included parties from the fossil fuel industry as defendants in the lawsuit, but said parties were removed as defendants during pre-trial proceedings. The plaintiffs range in age from 9 to 20 and ten of the children have either Black or Indigenous backgrounds. The lawsuit was launched while Obama was still in office, but in 2017 the plaintiffs substituted Trump's name for that of the former president.

Martinez along with his brother and sister, together the Earth Guardians, are on all music streaming platforms. Their first album, Generation Ryse, was released in August of 2014, and it includes eco hip-hop tracks like "What the Frack" and "Speak for the Trees". Through his music, he was highlighting specific environmental issues relevant to his state (Colorado) and facing the entire nation. Additionally, the album was aimed at today's youth in hopes of spreading their message of environmental awareness to their own generation.

In 2013, Martinez was awarded the U.S. Volunteer Service Award by President Barack Obama.
