The Salt River Pima-Maricopa Indian Community (SRPMIC) is a sovereign nation located in the metropolitan area of Phoenix, Arizona. The community is made up of two distinct tribes, the Pima and the Maricopa, who have lived in the area for thousands of years. The SRPMIC operates in the Regional Government sector and is committed to promoting sustainable development and protecting the environment. The community has made significant strides in decarbonisation and is a leader in renewable energy.

One of the key areas of focus for the SRPMIC is corporate energy. The community has implemented a number of initiatives to reduce its energy consumption and promote the use of renewable energy sources. One of the most significant projects undertaken by the SRPMIC is the installation of a 3.6-megawatt solar array on tribal land. The solar array generates enough electricity to power over 700 homes and has reduced the community's carbon footprint by over 5,000 metric tons of CO2 per year.

In addition to the solar array, the SRPMIC has also implemented a number of other renewable energy projects. The community has installed several small-scale wind turbines, which generate electricity for tribal buildings and facilities. The SRPMIC has also partnered with local utilities to develop a corporate power purchase agreement (PPA) for renewable energy. Under the PPA, the community purchases renewable energy credits from local utilities, which helps to support the development of new renewable energy projects in the region.

The SRPMIC has also implemented a number of energy efficiency measures to reduce its energy consumption. The community has retrofitted tribal buildings with energy-efficient lighting and HVAC systems, and has implemented a building automation system to better manage energy use. The SRPMIC has also implemented a green building policy, which requires all new tribal buildings to meet LEED certification standards.

The SRPMIC's commitment to renewable energy and decarbonisation is not limited to its own operations. The community has also implemented a number of initiatives to promote renewable energy development in the region. The SRPMIC has partnered with local utilities to develop a community solar program, which allows residents and businesses to purchase solar energy from a shared solar array. The community has also established a renewable energy fund, which provides financing for renewable energy projects in the region.

In addition to its renewable energy initiatives, the SRPMIC is also committed to protecting the environment and promoting sustainable development. The community has implemented a number of initiatives to reduce waste and promote recycling. The SRPMIC has also implemented a water conservation program, which includes the use of low-flow fixtures and the implementation of xeriscaping in tribal landscaping.

The SRPMIC's commitment to sustainability and renewable energy has earned it recognition from a number of organizations. In 2018, the community was awarded the Sustainable Communities Award from the Arizona Forward Foundation. The award recognized the SRPMIC's leadership in sustainable development and its commitment to reducing its carbon footprint.

In conclusion, the Salt River Pima-Maricopa Indian Community is a leader in renewable energy and sustainable development. The community has implemented a number of initiatives to reduce its energy consumption and promote the use of renewable energy sources. The SRPMIC's commitment to decarbonisation and corporate energy has earned it recognition from a number of organizations and serves as a model for other communities in the region. The SRPMIC's commitment to sustainability and renewable energy is a testament to its dedication to protecting the environment and promoting sustainable development.
