According to the Massachusetts Department of Environmental Protection, food waste makes up one-quarter of our state’s trash. That means your biodegradable apple cores and other plant based materials are needlessly taking up space in landfills and causing negative environmental impacts. But there’s an easy fix. Enter composting.

Composting is not new. In fact, as long as plants have been growing, compost has been happening. What do you think happens to all those leaves that fall off the trees in the forests? That’s right –- Mother Nature is the original compost queen!

Any good farmer will tell you that good compost is one of the best soil amendments around. What you should also know is that composting helps alleviate climate change.

It Works Like This

When organic materials like food and yard waste break down in a compost pile, with plenty of air and water present, the carbon that is released is stored in the new compost, instead of being sent out into the atmosphere. This carbon sequestration –- keeping the carbon “locked up” — helps reduce the greenhouse gasses that contribute to climate change.

If those same organic materials break down in a landfill, greenhouse gases like carbon dioxide and methane are released, contributing to warming our planet.

An Easy to Access Solution

According to calculations from Project Drawdown, an estimated 38% of food waste was composted in the U.S. in 2015. In the European Union, that number is much higher: nearly 57%.

Compost can happen on large or small scales. Some cities already collect household food waste. In 2009, San Francisco passed an ordinance that makes composting the city’s food waste mandatory. In Copenhagen, Denmark they have not sent organic waste to landfill for more than 25 years

Many towns in Massachusetts have a compost facility or “stump dump” for yard waste that homeowners and landscapers can use. They won’t take your kitchen waste of course, but it’s not hard to compost in your own yard.

How to Compost at Home

There are a few ways to compost. If you want reduce your waste and get all of the resulting “black gold” dirt, you can set up a compost pile relatively easily at home — find out how. Or, you can take advantage of curbside composting with companies like Black Earth, Dirty Boys, and Bootstrap Compost. In some towns, you can even drop off diverted food materials.

Pledge to Compost

If each one of us reduces our personal carbon footprint through composting, it can lead to significant reductions in greenhouse gas emissions across the state.  

I pledge to start composting at my home or in my garden. If I am already composting as an individual, I will work with my school, employer, or community group to set up a pilot composting program in the next 6 months.

Nature’s Way of Fighting Climate Change

We are now living in a world where scientists are telling us that urgent and unprecedented changes are needed if we are to avoid the most catastrophic impacts of climate change. Global average temperatures today are 1°C warmer than pre-industrial levels, and we are in the fight of our lives to avoid surpassing 1.5°C in the coming decades.

Often times, people ask “where is the technology that will save us?” When will scientists figure out how to build a magic vacuum that sucks all the excess carbon dioxide out of the atmosphere and help us continue living our lives as we do right now?

Instead of waiting for technology and innovation to save us, we need to look at one of the most historically significant, but underrepresented solutions to climate change: trees.

Why Trees?

Trees are vital to life on our planet for many reasons. They give us oxygen, store carbon, stabilize the soil, and provide habitat for our wildlife.

When it comes to climate change, trees not only help us by absorbing carbon dioxide (CO2) and other pollutant particulates, they also help us build resiliency to the increasing impacts of climate change such as increased precipitation, increased temperature, and more.

Maintaining the Massachusetts Tree Canopy

According to a 2017 Harvard study, more than half of Massachusetts is covered by forest, but the state loses about 7,000 acres of forest each year to development.

Our forests and lands offset about 15 percent of the carbon emissions that we emit each year. Carbon storage is just one of the many benefits provided by the world’s forests. With the right management practices, forests filter air and water and provide a home for a diverse range of species.

In addition to our large forested areas, Massachusetts also benefits from the Greening the Gateway Cities Tree Planting Program, which aims to increase the urban tree canopy 5-10% in select neighborhoods of former industrial cities. Thus far this program has planted over 8,000 trees across 13 Gateway Cities.

Trees vs Climate Change

Trees fight climate change in many ways, from the small scale (home & community) to the big scale (national parks and other conserved land).

At Your Home

  • Trees or shrubs planted to shade air conditioners help cool a home more efficiently, using less electricity.
  • According to the US Forest Service, just three trees properly placed around a house can save up to 30% of energy use.

In Your Community

  • Neighborhoods with well-shaded streets can be up to 6-10°F cooler than neighborhoods without street trees, thus reducing the need for increased energy usage.
  • Shaded parking lots also help keep automobiles cooler, reducing emissions from fuel tanks and engines.

Across Protected Lands

  • Forests store large amounts of carbon in their leaves, stems, and other parts of the plant. According to the USDA, forests make up 90% of the natural environments in the US that absorb carbon (otherwise known as the carbon sink) and sequester approximately 10% of US CO2 emissions.
  • For each area of forest protected, the threat of deforestation and degradation is removed, leading to reduced CO2 emissions.

Be a Climate Hero: Pledge to Plant a Tree

Planting trees is a strategy that can be implemented now and offers more additional benefits than nearly any other climate change solution.

Ready to be a climate hero? Sign our pledge and commit to planting a new climate resilient tree at home, in your community, or at your school this spring or fall.
