Reducing your personal carbon footprint

Household consumption indirectly accounts for over 70% of total U.S. emissions, with the average American household producing approximately 48 tonnes of carbon dioxide equivalent per year. This makes individual choices surprisingly impactful when multiplied across millions of people.

Cutting electricity use at home

Residential electricity use generated 582.2 million tonnes of carbon dioxide equivalent in 2022, representing nearly 9% of total U.S. emissions. Heating and cooling systems account for 41% of energy used in residential buildings. Simple changes like adjusting your thermostat by five degrees-cooler in winter and warmer in summer-can meaningfully reduce energy consumption.

Other effective steps include switching to LED lighting, unplugging electronics when not in use (standby mode accounts for 5-10% of residential energy use), and washing clothes in cold water. Simply using cold water for one laundry load per week can cut household emissions by about 70 pounds of carbon dioxide equivalent annually.

Minimizing air travel

Aviation has an outsized impact on emissions. A single long-haul flight from New York to Tokyo produces nearly 2 tonnes of carbon dioxide per person-almost matching the global average annual footprint of 5.9 tonnes per individual. A round-trip flight across the United States produces roughly 2 tonnes of carbon dioxide per person, representing about 10% of an American’s annual carbon footprint.

Where possible, consider alternatives like trains, which emit only 14 grams of carbon per kilometre compared to 285 grams for planes. When flying is unavoidable, purchasing carbon offsets or choosing direct flights (takeoffs and landings use the most fuel) can reduce the impact.

Adopting plant-rich diets

Food systems generate approximately one-third of global greenhouse gas emissions. Switching to a plant-based diet can reduce an individual’s annual carbon footprint by up to 2.1 tonnes with a vegan diet or 1.5 tonnes for vegetarians. Research published in Frontiers in Nutrition found that vegan diets reduce carbon emissions by 46% compared to omnivorous diets, while also cutting land use by 33%.

According to Project Drawdown, if 50-75% of people adopt a healthy diet with reduced meat consumption, at least 54-78 gigatonnes of emissions could be avoided from dietary change alone. You don’t need to go fully vegan-even reducing red meat consumption and incorporating more legumes, nuts, and vegetables makes a significant difference. Meat and dairy production significantly contributes to greenhouse gas emissions, with cattle producing substantial methane as part of their digestive process.

Advocating for systemic change

While personal choices matter, individual action alone cannot solve the climate crisis. Research indicates that just 100 companies are responsible for 71% of all global greenhouse gas emissions. This reality underscores the need for systemic transformation through policy advocacy and collective pressure.

Campaigning for city-wide renewable energy

Transitioning cities to renewable energy is one of the most impactful systemic changes possible. The World Resources Institute emphasizes working with utilities and policymakers to develop climate-resilient infrastructure that supports renewable energy and electric transport. Municipal governments can commit to 100% renewable energy targets, install solar infrastructure on public buildings, and support community solar programs.

Citizens can push for these changes by attending city council meetings, supporting local climate action plans, and voting for candidates who prioritize clean energy. Studies of German cities show that sustained public pressure led 64% of municipalities to introduce new climate policy instruments, including more ambitious emissions reduction targets.

Demanding better public transport

Transport produces a quarter of all energy-related emissions, with 95% of transport energy still coming from fossil fuels. Expanding public transit, creating safe cycling infrastructure, and improving walkability are essential systemic solutions.

Solutions must bring jobs and services closer to where people live while promoting public transportation, walking, cycling, and other low-carbon alternatives. Advocate for your city to invest in electric bus fleets, protected bike lanes, and frequent, affordable transit service. The UN Climate Champions framework calls for investing at scale in public and collective transport, railway, safe walking, cycling, and micro-mobility networks.

Spreading climate awareness

Education and awareness-building are crucial multipliers of climate action. When more people understand the urgency of the crisis, political will for systemic change grows stronger.

The power of youth voices

Fridays for Future, sparked by Greta Thunberg’s solitary protest outside the Swedish parliament in 2018, grew to mobilize nearly 6 million people during the Global Week of Climate Action just one year later. The movement demonstrates how young people can shape public discourse and policy.

Research published in Humanities and Social Sciences Communications notes that youth-led movements have successfully utilized legal avenues and formed alliances with NGOs to challenge political objectives through litigation. Young climate activists today perceive climate change as connected to the same economic and political roots that produce other forms of injustice-their demand is climate justice and systemic transformation.

Studies show that Fridays for Future activists effectively use personalisation as a powerful tool in climate storytelling, making global issues feel local and actionable. By establishing localised social media channels and highlighting community-specific environmental challenges, activists enhance feelings of self-efficacy among their audiences.

You can contribute by sharing accurate climate information, highlighting local environmental victories, and amplifying the voices of climate scientists and frontline communities. Social platforms allow direct communication with the public, bypassing traditional media gatekeepers.

Supporting environmental movements

Local environmental struggles often represent the front lines of the global climate fight. Supporting these movements connects individual action to broader systemic change.

Connecting local struggles to climate justice

Race-even more than class-is the leading indicator for the placement of toxic facilities in the United States. Communities of colour and low-income neighbourhoods disproportionately bear the burden of pollution from coal plants, incinerators, and industrial facilities that also emit greenhouse gases.

The environmental justice movement, originating from protests in Warren County, North Carolina in 1982, recognized that environment is another front in the struggle for justice. Today, activists understand that fighting against a local coal plant or protecting a threatened wetland directly contributes to reducing emissions while advancing social justice.

Examples of impactful local action

The Alliance for Appalachia works to end mountaintop removal coal mining while supporting a sustainable, just economy in the region. Research shows that coal extraction has occurred disproportionately in low-income, higher-poverty areas, even as the energy produced benefits the rest of the country.

A just transition to a green economy requires policies that retrain displaced workers and shield vulnerable communities from the economic impacts of phasing out fossil fuels. By supporting environmental justice organizations, participating in local campaigns, and advocating for policies that protect both people and planet, individuals can help build the broad coalition necessary for meaningful change.

Taking action in your community

The Climate Reality Leadership Corps has trained over 31,000 activists worldwide, equipping them with climate science knowledge and organizing skills. Consider joining or supporting organizations working on local environmental issues-whether opposing polluting facilities, protecting green spaces, or advocating for environmental regulations.

Pressuring leaders and businesses to act boldly is essential, and campaigns like the UN’s ActNow encourage civic engagement. Sharing knowledge empowers communities and drives the cultural shifts necessary for lasting change.

The path forward

Combating climate change requires action at every level-from individual lifestyle changes to collective advocacy for systemic transformation. Each choice to reduce emissions, every voice raised for policy change, and all support given to environmental movements contributes to the larger effort. The EAT-Lancet Commission concluded that without substantial changes to the food system alone, the worst effects of climate change will be unavoidable, even with a successful energy transition.

The climate crisis demands urgency, but it also offers opportunity-to build cleaner cities, healthier communities, and a more just world. The tools exist; what’s needed now is the collective will to use them.

What do you think? Which actions-personal or systemic-do you believe would have the greatest impact in your community? How might you connect with local environmental movements to amplify your efforts?
