Major Initiatives


Paris agreement

The United Nations Framework Convention on Climate Change (the "Paris Agreement") brings together 197 countries under a common framework for reducing greenhouse gas emissions, limiting global temperature rise to well below two degrees Celsius above preindustrial levels.

The Paris Agreement embodies a global response to the decades-long scientific consensus that human activity is causing global temperatures to rise at unprecedented rates; and calls upon individual countries to establish Nationally Determined Contributions towards greenhouse gas emissions reductions and climate resilience.

Mayor's Commitment to 35% Canopy Cover by year 2035

The City and County of Honolulu has committed to a goal of obtaining a 35 percent canopy cover in urban areas by the year 2035. Currently, the island’s urban areas have a canopy cover of approximately 25 percent. This goal is accelerated by Mayor Caldwell’s commitment as a signatory to the Chicago Climate Charter in December 2017, with the additional specific commitment to plant 100,000 new trees by 2025.

President Trump's decision to withdraw the United States from the Paris Agreement spurred over 380 cities in the U.S., numerous cities in other parts of North America, and countless organizations worldwide to commit themselves to the Agreement. 

These commitments championed and organized by Climate Mayors, the We Are Still In Campaign, and the Global Covenant of Mayors for Climate & Energy ("Global Covenant") demonstrate strong local leadership to citizens at home and abroad.

Cities in North America, together with their counterparts around the globe, are engaged and ready to act.

The Global Covenant has called for member cities to set targets that are at least as ambitious as their respective countries' Nationally Determined Contributions, and through their commitments cities within North America are already on target to reduce emissions by 2.72 Gigatons CO2e by 2030 or the equivalent of taking over 585 million cars off the road.

Honolulu Becomes a Member of Powering Past Coal Alliance

Honolulu is part of the “We Are Still In” initiative, which brings together over 2500 subnational governments, private businesses, and public organizations in the U.S. that are committed to upholding the goals of the Paris Agreement. The Honolulu Office of Climate Change, Sustainability and Resiliency is developing the city’s first-ever climate action and adaptation plan. Mayor Kirk Caldwell has been an advocate for climate action, and highlighted energy conservation as one of his top priorities for mayor.

Hawai‘i's Mayors commit to shared goal of 100% renewable ground transportation by 2045

Honolulu Mayor Kirk Caldwell, Maui County Mayor Alan Arakawa, Kauaʻi County Mayor Bernard P. Carvalho Jr. and Hawaiʻi County Managing Director Wil Okabe, representing Mayor Harry Kim, have pledged to transform Hawaiʻi’s public and private ground transportation to 100 percent renewable fuel sources by 2045.

Ground transportation accounts for over one-quarter of Hawaiʻi’s imported fossil fuel consumption and greenhouse gas emissions. It also represents a significant financial gain for our residents as operating and maintaining an electric vehicle costs about one-third less than a comparable vehicle powered by fossil-fuel.

The signed proclamations solidify Hawaiʻi’s role as a global renewable energy leader, with the state and all four counties becoming the first in the nation to commit to a 100 percent renewable transportation future.

The four Hawaiʻi mayors join leaders in France, Great Britain, India, China, Dublin, Madrid, Oslo, Milan, Paris, and Brussels who have also committed to transition their transportation systems away from fossil fuels.
