Mayor Caldwell pledges continued support of solar energy as report ranks Honolulu #1 in nation

Honolulu – Mayor Kirk Caldwell has co-signed a public letter with the Mayors for Solar Energy to reiterate his support for clean, renewable energy (letter attached). The bipartisan group of 180 U.S. mayors, representing cities large and small in 42 states, resolve to make solar power a key element of their communities’ energy plans and call on others to embrace clean energy from the sun.

“Solar on thousands of homes and government buildings is helping Honolulu reach our sustainable energy goals,” said Mayor Caldwell. “We are on the front lines of sea level rise and other climate change effects and we must drastically reduce our use of fossil fuels. My administration is working to expedite permits for photovoltaic and battery storage systems and the results are clear.”

The move by mayors to promote solar power comes at a time when the federal administration is rolling back Obama-era policies aimed at reducing climate emissions and encouraging renewable energy.

“Oʻahu moved up to 21 percent renewable in 2017 from 19 percent the year before, and the lion’s share of that growth came from private rooftop solar installation,” said Josh Stanbro, the City and County of Honolulu’s Chief Resilience Officer. “Local governments and cities are leading on climate change policy right now, and our residents are also stepping in to help build a solar future from the ground up.”

The commitment from Mayor Caldwell to accelerate the transition to solar comes on the heels of a new report released by Environment America called “Shining Cities: How Smart Local Policies are Expanding Solar Power in America.” The report found that Honolulu ranks first in the nation for installed solar capacity per capita in the United States. Honolulu also jumped up to the No. 3 slot for total solar installed in a city. For a link to the Environment America report, click here.

“It is really exciting to see Honolulu rise in the rankings of volume of overall solar capacity,” said Aki Marceau of Elemental Excelerator, a nonprofit that has funded 35 clean energy, transportation, water, and agriculture projects with startups in Hawai‘i.  “Local businesses, utilities, and state and city agencies have stepped up to make this possible. We hope to see this kind of engagement with new, clean technologies beyond solar.”

In 2016, nearly 2,000 people were employed in solar jobs on Oʻahu, and solar permits issued in February 2018 on Oʻahu were 26 percent higher than the previous year – signaling the potential for expanded growth in the sector through 2018. Mayor Caldwell and the city’s Department of Planning and Permitting have been working with the renewable energy industry to streamline battery storage and photovoltaic (PV) approvals, which helped lead to the expansion.

William Giese, Executive Director of the Hawaiʻi Solar Energy Association, lauded the commitment by Mayor Caldwell and pledged to continue to keep Honolulu at the top of the list. “The Hawaiʻi Solar Energy Association will continue to work with Mayor Caldwell and the City and County of Honolulu to bring more solar to Oʻahu, lower electric bills, increase customer choice, and drive Hawaiʻi towards 100 percent clean energy.”

While residents can save money with solar panels on their roof, the entire community benefits from increased renewable energy production.

“Cities everywhere should take steps to switch to solar energy,” said Emma Searson, Environment America’s Go Solar Campaign Coordinator. “By tapping into the power of the sun, cities can benefit from cleaner air and improved public health, while simultaneously tackling climate change.”

Bill 15 (2018)- Support for Office of Climate Change, Sustainability, and Resiliency

Testimony needed to support Bill 15 (2018)- the Office of Climate Change, Sustainability, and Resiliency budget, which has a hearing on Wednesday, April 11th at 9 AM!

In 2016, O‘ahu residents voted to establish an “Office of Climate Change, Sustainability, and Resiliency” through a City Charter Amendment. Last year, the O‘ahu Group diligently advocated for the Honolulu City Council to fully fund this new office, and we succeeded! With 7 full-time positions, the Office has already been making progress on climate change planning, community and stakeholder outreach, clean energy projects, and improving the resiliency of our coastal zones and waterways. This Office also supports the work of the City’s Climate Change Commission and spearheaded efforts for the 4 County Mayor’s commitment towards a 100% Renewable Transportation goal by 2045. Woohoo!

but the 2019 budget for this Office needs to be approved by the Honolulu City Council and we need testimony submitted in support once again! 

How you can help:

Please submit online testimony in support for Bill 15 (2018) before April 11th, when it will be heard in the City Council’s Budget Committee. Bill 15 (2018) is an Executive Operating Budget bill that includes a request of $1,148,764 for the Office of Climate Change, Sustainability, and Resiliency, which is focusing efforts on implementing the Paris climate agreement, improving energy efficiency in City buildings and fleets, and developing a Resilience Strategy for Honolulu, including a Climate Action Plan.

Revised Comments for the O‘ahu General Plan

Below are some of the comments the Sierra Club O‘ahu Group gave before the Honolulu Planning Commission at their March 21, 2018 meeting in regards to the updated proposed O‘ahu General Plan. The O‘ahu General Plan is a document that helps guide future development throughout the island and it is long overdue for an update. Mahalo to Honolulu Planning Commission under the leadership of Chair Ka‘iulani Sodaro for taking in consideration many of the concerns the O‘ahu Group provided on the O‘ahu General Plan in relations to population, short-term vacation rentals, and renewable energy. We are pleased that the plan continues to emphasize language relating to climate change, sea level rise, renewable energy, agriculture, and transit-oriented development. Major amendments to the O‘ahu General Plan that were adopted by the Planning Commission include:

  • Reinstate language to “Publicize the desire of the City and County to limit population growth.”
  • Retain language: “manage” instead of “facilitate” for “the development of secondary resort areas: Ko‘olina Resort, Turtle Bay Resort, Hoakalei Resort at Ocean Point, Mākaha Valley, and La‘ie, in a manner which respects existing lifestyles and the natural environment, and avoids substantial increases in the cost of providing public services in the area.”

According to DPP, these areas were named specifically because they have already been authorized as secondary resort areas.

  • Strike language to “Consider small-scale community oriented visitor accommodations in non-resort areas with attention to community input, compatibility of uses, infrastructure adequacy, and the ability to enforce effectively.”

Essentially this would help prevent the further proliferation of short term vacation rentals in residential communities.

  • Combine policy language: “Support and encourage programs and projects, including economic incentives, regulatory measures, and educational efforts, which will reduce O‘ahu’s dependence on fossil fuels as its primary source of energy. Promote and assist efforts to establish safe and adequate fossil fuel supply reserves within Hawai’i’s boundaries until Hawai’i reaches its renewable energy goals.

This took into consideration our issue that we should not be promoting any more fossil fuels for O‘ahu, as our State has already committed to 100% clean energy by 2045.

7 changes were made and adopted at this meeting, including the four above. The next step for the O‘ahu General Plan is to be adopted by the City Council. We will continue to advocate for sound environmental policy to be included in the O‘ahu General Plan.

Below are our written comments which we used as a basis for our oral testimony during the public meeting:

Mahalo for your support.

Hawaiʻi’s mayors oppose Trump Administration repeal of Clean Power Plan

Hawaiʻi’s mayors oppose Trump Administration repeal of Clean Power Plan

Honolulu, Hilo, Wailuku, and Līhuʻe — Leaders from the City and County of Honolulu, Hawaiʻi County, Maui County, and Kauaʻi County have joined 233 mayors, from 46 US states and territories, representing over 51 million Americans to oppose the Trump Administration’s proposed repeal of the Clean Power Plan (CPP).

Honolulu Mayor Kirk Caldwell, Hawaiʻi County Mayor Harry Kim, Maui County Mayor Alan Arakawa, and Kauaʻi County Mayor Bernard P. Carvalho Jr. all signed onto a letter in opposition to the Environmental Protection Agency’s proposed Repeal of Carbon Pollution Emission Guidelines for Existing Stationary Sources: Electric Utility Generating Units.[1]

“The Clean Power Plan is a fundamental building block in the nation’s response to climate change, and was a hallmark achievement of the EPA under the Obama Administration,” said Mayor Caldwell. “The Clean Power Plan encourages communities to embrace a future that will lead to new opportunities, cutting edge technology and higher paying jobs. This is a vision the City and County of Honolulu has embraced and it’s already paying dividends through sound planning for new infrastructure.”

With over a third of global greenhouse gas (GHG) emissions coming from the electricity sector, the four mayors recognize that the Clean Power Plan is essential to the United States’ ability to curb future GHG emissions and live up to its commitments under the Paris Agreement. All four mayors previously joined Governor David Ige on June 5, 2017 to commit to uphold the Paris Agreement just days after President Donald J. Trump announced he would withdraw the United States from the international accord to address global warming.

“It is important for the federal government to lead our transition to a cleaner, healthier, more affordable, and more resilient energy future,” said County of Hawai‘i Mayor Kim. “The Clean Power Plan is a step in the right direction and is aligned with local efforts to reduce greenhouse gases, improve energy efficiency, and use renewable energy sources. This is a mission that we must all be a part of.”

Signing the letter signals Hawaiʻi’s continued commitment to transition away from dependence on fossil fuels and reinforces a 2015 state law that requires 100 percent of Hawaiʻi’s electricity to be generated by renewable sources by 2045. Hawaiʻi’s 2045 goal was the nation’s first such benchmark.

“The benefit of the Clean Power Plan is twofold: Providing direct health benefit from avoiding air pollutants from combustion, along with reducing greenhouse gas emissions,” stated Maui Mayor Arakawa. “It is gratifying to stand in solidarity with so many mayors at the local level, where power plants pollute, and continue down the path of a cleaner future.”

Hawaiʻi is the only state that entirely supports the Climate Mayors network through its four mayors’ participation. In signing this letter opposing repeal of the CPP, they are joined by other members of the Climate Mayor’s network (, which includes Los Angeles, Houston, Portland, New York, and Puerto Rico.

“Kaua‘i County is working hard to reduce our greenhouse gas emissions because we understand the cost of inaction. Everyone – at all levels of government, from small towns, to states, all the way up to our federal government, needs to be a part of this,” stated Mayor Carvalho Jr. “The Clean Power Plan is a key piece of that effort across the U.S.”

The actions announced today by the chief executives of the four counties are in alignment with the state of Hawaiʻi’s recent commitment to the goals of the Paris Agreement that seeks to reduce GHG emissions and keep global warming below 1.5 degrees Celsius. Sea level rise is contributing to coastal erosion that recently destroyed part of a historic cemetery on Maui and caused a bike path on the North Shore of Oʻahu at Sunset Beach to partially collapse; and according to the recently published Hawaiʻi Sea Level Rise Vulnerability and Adaption Report, the expected future sea level rise is estimated to cost $19 billion in “loss of land and structures” along with 6,500 flooded structures, 38 miles of flooded major roads, and 19,800 displaced people.[2]

On December 12, 2017, the four mayors came together on the Polynesian voyaging canoe Hōkūleʻa in committing to transform Hawaiʻi’s public and private ground transportation to 100 percent renewable fuel sources by 2045.


The Clean Power Plan was originally proposed in August 2015. It was a signature policy achievement of the EPA under the Obama Administration, and was shaped by years of unprecedented outreach and public engagement.

Shortly after issuance of the final rule, 27 states, led by current EPA Administrator Scott Pruitt in his prior capacity as Attorney General of Oklahoma, challenged the CPP on a range of legal and technical concerns. The U.S. Supreme Court stayed the CPP in response, immediately halting implementation in February 2016.

On October 10, 2017, the EPA filed its proposal to repeal the Plan. Governor Ige posted a statement opposing the Trump Administration’s proposal to repeal on October 11, 2017.

Climate Change Commissioners sworn in






Honolulu – A swearing in ceremony was held today in Honolulu Hale for the five members of the new Climate Change Commission: Rosanna ‘Anolani Alegado, Makena Coffman, Charles ‘Chip’ Fletcher, Victoria Keener, and Bettina Mehnert. Mayor Kirk Caldwell appointed all five commission members, who were confirmed by the Honolulu City Council earlier in the day.

Mayor Caldwell, Managing Director Roy K. Amemiya Jr. and Deputy Managing Director Georgette Deemer attended the ceremony after the oath of office was administered to the five commission members, thus affirming their positions as officers of the city.

The Climate Change Commission was created after O‘ahu voters approved an amendment to the City Charter in the 2016 general election that mandated the creation of the new panel. The role of the Climate Change Commission is to gather the latest science and information on climate change impacts to Hawai‘i and provide advice and recommendations to Mayor Caldwell, executive departments and the City Council as they look to draft policy and engage in planning for future climate scenarios.

“The five members of the Climate Change Commission are experts in their respective fields and will have a tremendous impact on our island city as we embark on a new era of sustainability and resiliency in the face of sea level rise and increased storm risk,” said Mayor Caldwell. “I thank each of them for taking on this volunteer role and I know their hard work will result in progress that will benefit our residents for decades to come.”

Commission members have agreed to meet at least once every month with the first meeting scheduled on Wednesday, February 7, at 3 p.m. in the City Council Meeting Room in Honolulu Hale.

“Our office is thrilled that Mayor Caldwell has selected a diverse group of global and local climate experts to this important commission and that the City Council confirmed all of them unanimously,” said Josh Stanbro, executive director of the city’s Office of Climate Change, Sustainability and Resiliency, who also serves as the city’s Chief Resilience Officer. “It is critical that we base our policies on data and the latest science in order to protect our quality of life and O‘ahu’s economy for the long-term.”
