Act on Climate Change

Green Cities and Local Governments

Local Leaders Making the Difference

Cities have the greatest capacity to impact the quality of the air, water, land, and climate we depend on for survival. Primarily responsible for the wellbeing of their citizens, local governments have a responsibility to respond to these challenges by taking climate action.

The Green Cities and Local Governments campaign engages with cities to respond to climate change by providing resources, partnerships and a platform to take climate action. Cities are uniquely positioned to directly respond to community needs and bring people together.

EARTHDAY.ORG calls on local officials to join over 200 cities and counties nationwide who have prioritized public health and sustainable economic growth by declaring a climate emergency

Use the resources below to call or email your local officials demanding swift and comprehensive action on climate:

The first and most essential step to become a Green City is to form a comprehensive sustainability plan. Implementing the following policies in municipal buildings and institutions will not only save up to millions of dollars in taxpayer funds but will also assist in scaling these initiatives up for city-wide adoption.

Policy Recommendations for Local Sustainability

EARTHDAY.ORG recommends including the following policies to help reach net-zero emissions:

• Developing and implementing a plan for all public transportation to run on renewable energy.
• Mandating green roofs for all buildings.
• Planting trees to protect human health, conserve natural spaces, and mitigate climate impacts.
• Significantly expanding or creating pedestrian and bicycle-only zones in the city.
• Establishing a carbon pricing or taxing scheme.
• Launching a major clean energy or green infrastructure project, taking climate justice into account.
• Setting high building efficiency standards for development projects and building upgrades.

Natural spaces are essential to a healthy human habitat in which citizens can prosper. EARTHDAY.ORG suggests the following policy measures to ensure that constituents’ conservation needs are met:

• Planting trees to protect human health, conserve natural spaces, and mitigate climate impacts.
• Developing a biodiversity protection strategy & establishing green corridors for wildlife in your city.
• Expanding or creating significant stretches of new green spaces, especially in marginalized and low-income areas.
• Launching a major clean energy or green infrastructure project, taking climate justice into account.
• Revitalizing waterfronts.

The following measures can be taken to improve efficiency and reduce strain on city trash services:

• Banning or taxing any or all the ten most common single-use plastics.
• Creating a Zero Waste or Circular Economy plan.
• Passing stricter clean water and clean air ordinances.
• Revitalizing waterfronts.
• Expanding access to recycling and composting services.

Earth Day 2021 Global Day of Conversation Toolkit

We ask that you sign the proclamation within this toolkit and submit a short 1-2 minute video from Government officials to include

  • Commit to mandatory climate and environmental literacy training for 100 percent of your government staff. 
  • Commit to lowering your jurisdiction’s carbon emissions with a goal of lowering your emissions in half by 2030 and net zero emissions by 2050.
  • Commit to integrating climate and environmental justice into all community decision making.

Videos will be highlighted on our Green Cities webpage and social media on a rolling basis.   

Cities around the world are leading the way and developing innovative plans — ordinances, citywide strategies, public outreach and education campaigns — to drive climate action and resilience, and we’re here to help. Cities and local governments can implement climate action when state and federal governments drag their feet. 


Mayors and local officials can lead the climate effort by making Earth Day a community-wide affair, bringing together community partners and local stakeholders to showcase innovative solutions, launch bold new initiatives and support civic action for the environment. 

Earth Day campaigns build ambitious, inclusive movements that engage with every aspect of society. Mobilizations infuse people with a sense of purpose and enhance their ability to create meaningful change and participate in the success of local initiatives. These efforts focus on elevating science and promoting action and volunteerism on behalf of the environment and expanding environmental education. 

Cities are growing at a rapid pace; making cities green is a necessary step in preparing for a healthier, more sustainable future. Through a global network of local government partners, we hope to mobilize millions of people to show the collective impact of local action and amplify the demand for climate action from national governments.
